How are the app reviews queued?
Hi, I was wondering about Apple's review queues. I have an app that in waiting for review for almost a week now but review time trackers claim average waiting times less than a day: https://www.runway.team/appreviewtimes My previous experience is also quite inconsistent, can you please shed some light on how things work internally? In this time I have done some improvements on the app that I was considering for the next update, should I cancel and re-submit?

StoreKit returns no in-app subscriptions on TestFlight despite correct App Store Connect configuration
Hello Applet, I’m experiencing an issue with StoreKit on a TestFlight build. My app uses auto-renewable subscriptions through StoreKit and RevenueCat. Configuration already verified: App installed through TestFlight (not debug). Bundle Identifier: com.ciborgu.vytalai Paid Applications agreement is active. In-App Purchase capability is enabled. Three auto-renewable subscriptions exist in App Store Connect. Product IDs match exactly between App Store Connect, RevenueCat and the application. RevenueCat initializes successfully. A Sandbox test account has been created. Tested on a physical iPhone. Device restarted and app reinstalled from TestFlight. VPN and iCloud Private Relay disabled. When attempting to purchase a subscription, the Apple payment sheet never appears. Our diagnostics indicate that StoreKit does not return any available products for the configured Product IDs, preventing the purchase sheet from opening. Expected Product IDs: vytalai_premium_monthly vytalai_premium_yearly vytalai_premium_yearly_intro Could you please verify if there is any issue with the App Store Connect configuration, StoreKit availability, or the processing state of these subscriptions on Apple’s side? If additional logs or diagnostics are required, I can provide them. Thank you. I have already contacted Apple Developer Support regarding this same issue. Previously, I was advised to schedule a technical support meeting. However, when I requested the meeting, my request was declined because of the subject of my issue, so I was unable to speak with an Apple engineer. Since I have now completed all the recommended troubleshooting and the issue still persists, I would greatly appreciate it if this case could be reviewed by the appropriate technical team or a StoreKit engineer. Thank you for your assistance.

watchOS 27 Developer Beta: App Switcher no longer accessible via double-press of Digital Crown
Hello, I updated my Apple Watch SE 3 (GPS + Cellular, 44 mm) to watchOS 27 Developer Beta (Build 24R5289n) and noticed what appears to be a change in the Digital Crown behavior. After the update: • A single press of the Digital Crown now shows fewer applications, which seems consistent with the changes announced for watchOS 27. • However, a double press of the Digital Crown no longer opens the App Switcher as it did previously. • As a result, I can no longer access the interface that allowed users to view recent apps and force-close applications by swiping them away. Before updating, double-pressing the Digital Crown opened the App Switcher and provided a way to close running apps. That functionality now appears to be missing. I would like to know whether: This is an intentional design change in watchOS 27. This is a known issue in the current Developer Beta. There is a new gesture or workflow for accessing recent apps and force-closing applications. Device: Apple Watch SE 3 (GPS + Cellular) 44 mm Aluminum Model: MEPJ4LW/A Software: watchOS 27.0 Developer Beta Build: 24R5289n The behavior is reproducible after restarting the watch. Thanks.

Timestamp counter heap always returns zero
Hi, I am trying to use a timestamp counter heap, but it always seems to report timestamp zero. Consider this example program: #include <Metal/Metal.h> #include <assert.h> int main(int argc, char *argv[]) { auto device = MTLCreateSystemDefaultDevice(); assert(device); auto descriptor = [MTL4CounterHeapDescriptor new]; [descriptor setType:MTL4CounterHeapTypeTimestamp]; [descriptor setCount:1]; auto heap = [device newCounterHeapWithDescriptor:descriptor error:nullptr]; assert(heap); [heap invalidateCounterRange:NSMakeRange(0, 1)]; auto command_buffer = [device newCommandBuffer]; assert(command_buffer); auto allocator = [device newCommandAllocator]; assert(allocator); [command_buffer beginCommandBufferWithAllocator:allocator]; auto encoder = [command_buffer computeCommandEncoder]; assert(encoder); [encoder writeTimestampWithGranularity:MTL4TimestampGranularityPrecise intoHeap:heap atIndex:0]; [encoder endEncoding]; [command_buffer endCommandBuffer]; auto queue = [device newMTL4CommandQueue]; assert(queue); auto event = [device newSharedEvent]; assert(event); [queue commit:&command_buffer count:1]; [queue signalEvent:event value:1]; [event waitUntilSignaledValue:1 timeoutMS:UINT64_MAX]; auto data = [heap resolveCounterRange:NSMakeRange(0, 1)]; printf("size %lu: %llu\n", data.length, *(uint64_t*)data.bytes); return 0; } Trying to compile and run: % clang++ -g -O0 -o test test.mm -framework Metal -framework Foundation && MTL_DEBUG_LAYER=1 ./test 2026-06-23 14:44:48.006 test[26472:1588857] Metal API Validation Enabled size 8: 0 I would have expected to receive size 8: [some random non-zero number] that number being a GPU timestamp of when the command was executed, but I always get zero. Does anybody have an idea of what I am doing wrong?

SwiftUI 6 AttributeGraph warnings in console
On a MacBook Air M4 running macOS Sequoia 15.7.7, the following tiny code does warn inside the Xcode 26.3. Here is the whole console output: === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 110216 === === AttributeGraph: cycle detected through attribute 110216 === === AttributeGraph: cycle detected through attribute 110284 === === AttributeGraph: cycle detected through attribute 110284 === === AttributeGraph: cycle detected through attribute 110216 === === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 110216 === Here is the full code: import SwiftUI @main struct myApp: App { var body: some Scene { WindowGroup { BaseView() } } } struct BaseView: View { @State private var isWorking: Bool = false var body: some View { Button("Go") { Task { // AttributeGraph warnings await MainActor.run { isWorking = true } await MainActor.run { isWorking = false } // No warnings at all // DispatchQueue.main.async { isWorking = true } // DispatchQueue.main.async { isWorking = false } } } .disabled(isWorking) .padding() } } You can see with DispatchQueue.main.async {...}, warnings aren't there. After a few days struggling with different AI support (Claude, ChatGPT, Perplexity), I didn't find any way to fix my own code. This tiny code is just there to show the issue. I tested multiple workarounds without finding one that fits to my app context. Thanks in advance for your support.

Universal Links failing for some users but working for others
Hi, We are facing an issue where Universal Links are working for most users but failing for some of our clients. For affected users: Links open in Safari instead of the app, or Universal link routing does not work as expected For other users: The same links open the app correctly What we verified Associated Domains capability is configured correctly AASA file is valid and accessible App configuration and bundle ID mapping are correct AASA: https://www.gartner.com/apple-app-site-association Issue Since the problem is only affecting a subset of users, we are unable to: Reproduce the issue consistently Identify when or why the association breaks Ask Has anyone experienced: Universal Links failing only for certain users/devices? What are the possible causes and how can we debug or proactively identify the root cause in such cases? Any guidance would be helpful. Thanks!

Xcode Bug Installed Platforms
Hello, I’m using the latest version of Xcode, 26.6. I’m unable to permanently delete old installed iOS platform versions. I remove them from Xcode settings, and the deletion appears to complete successfully, but after rebooting my Mac they appear again, as if nothing had changed. Do you have any suggestions for how to remove them correctly and permanently?

Labels in toolbar menu get wrapped when upgrading from iOS 18 to 26
When upgrading an app from iOS 18 to iOS 26, some labels in a toolbar menu get wrapped unexpectedly. The issue can be reproduced through the sample below, which contains this label : "Envoyer une réaction" On iPhone with iOS 18, the label is displayed on 1 line. But on iPhone with iOS 26, the label is displayed on 2 lines. No improvement was obtained through these modifiers : .lineLimit, .frame and .fixedSize . . How to avoid this unnecessary label wrapping that disrupts the readability ? . . import SwiftUI struct SampleView: View { var body: some View { NavigationStack { Color.clear .toolbar { ToolbarItem { Menu { Button(action: {}) { Label("Envoyer une réaction", systemImage: "envelope") } } label: { Image(systemName: "ellipsis") } } } } } } #Preview { SampleView() }

M4 Mac Mini: Xcode generates private keys with wrong label - codesigning impossible
M4 Mac Mini: Xcode generates private keys with wrong label - codesigning impossible Background This is a follow up to my November 2024 thread "Keychain issues after installing backup on new Mac" which was closed because I had a temporary workaround. That workaround using my wife's MacBook Air for signing is not sustainable. I used AI assistance to determine the root cause. My DTS case 102877839447 is open but has not yet been forwarded to a DTS engineer.

PHPickerViewController: UI rendering failure and data retrieval errors on iOS 17 & 26.4
Description: I am encountering critical issues with PHPickerViewController using the "Zero-Permission" configuration. The behavior differs significantly between iOS 17 and iOS 26.4, but both prevent successful image selection. Observed Behaviors: On iOS 26.4 (iPhone 17 Pro Max): The PHPicker UI fails to render the photo grid entirely. Upon initialization, the system UI displays an "Unable to load photo" alert, preventing users from even viewing or selecting images. On iOS 17: The picker UI loads, but after the user selects an image and adds it, the subsequent itemProvider.loadObject call consistently fails, returning an error and preventing our app from retrieving the image data. Current Implementation: var config = PHPickerConfiguration() config.filter = .images config.selectionLimit = pickLimit // Problematic logic: if ABTestManager.shared.isPHPickerCurrent { config.preferredAssetRepresentationMode = .current } let pickerVC = PHPickerViewController(configuration: config) pickerVC.delegate = self user device Images: What I have tested: I have been using preferredAssetRepresentationMode = .current in my AB tests. I have not yet tested .compatible mode, as my application logic requires access to high-fidelity assets. However, the current behavior suggests a regression or a fundamental incompatibility with how the system handles image containers for high-end hardware (e.g., iPhone 17 Pro Max) in the out-of-process picker. Supporting Documentation: Minimal Reproducible Project: [Attached] Logs: [Attached sysdiagnose logs] My Questions: Is the "Unable to load photo" UI failure on iOS 26.4 a known limitation for certain high-resolution asset types when using .current mode? Are there specific handling requirements for NSItemProvider when the system fails to resolve the image data in .current mode on older iOS 17 devices? Given that these failures occur in a "Zero-Permission" context, are there specific metadata or image processing constraints I should be aware of to prevent the picker from entering a "failed" state?

iOS build stuck in "Waiting for Review" — macOS/tvOS of same version already approved (App ID 6763137740)
Hello App Review Team, I'm hoping someone can take a manual look or point me in the right direction. The iOS build of my app has been sitting in "Waiting for Review" with no status change, while the macOS and tvOS builds of the exact same version have already been reviewed and released. App: VixioTV - IPTV & M3U Player App ID: 6763137740 Platform: iOS (iPhone/iPad) Current status: Waiting for Review Most recent submission: [June 24, 2026] Time in queue: ~24 days with no status change Related case IDs: [your expedited review / Developer Support case numbers] Context I'd like to share proactively: This is an update to an app that is ALREADY LIVE on the App Store (current iOS version 1.2). It is not a new app. The macOS and tvOS versions of this same update have already passed review and are live — only the iOS build is stuck. VixioTV is a bring-your-own-content player: it provides no broadcasts or content of its own. Users connect their own IPTV subscription (API credentials or an M3U URL). There is no registration, subscription, or content sale inside the app. I have submitted expedited review requests and contacted Developer Support, but I've only received generic/automated replies with no change in status. I would really appreciate it if someone could: Confirm whether there is any issue with the build, metadata, agreements, or account that requires action on my side. Indicate whether this is queue congestion or a submission-specific hold. If possible, escalate or trigger a manual review. Thank you very much for your help. Selcuk Kaymaz

StoreKit 2: New offer code NOT in Transaction.currentEntitlements()
This is production issue with a user completely stuck: User entered an offer code for 1 year free --> validated under iOS > Apple Account > subscriptions: it correctly shows a 1 year free trial But the transaction is not listed in his Transaction.currentEntitlements() Even after a restore (App.sync()) The Apple Account has always been the same (no mix) This is with the new offer codes introduced in 2026 Also, user wanted to pay the subscription himself in order to unlock the situation, he cannot because of the 'active' offer.

Single Build / Archive for iOS and Catalyst Build
So I am adding Catalyst support to my iOS app. I went through and updated my code and Build Settings to add Catalyst support. I can build for any iOS build or macOS build. I went into App Store Connect and then added a macOS build. I am not able to do a single build and archive that uploads a build for both macOS and iOS. I can do a build and archive for "Any iOS Device (arm64)" and it shows up in the iOS test flight. I can do a build and archive for "Any Mac (Mac Catalyst, arm64, x86_64) and it shows in the macOS test flight. Maybe I'm making a bad assumption ( I could not find any documentation on it) but I assumed Catalyst was a single build and archive that showed up in BOTH macOS and iOS sections. The build settings seem to imply the build is good for a single build and archive process. I want this to be a universal app and my assumption doing it that way would keep everything in sync when you push to the App Store. You can already download the app through the App Store but it is a version of the iPad app. I was hoping to make it more native and available in the Mac App Store without the iPhone/iPad app option. Am I making bad assumptions? Will I just have to do two Build and Archives for every build? I just want to make sure I'm doing this correctly and the best way.

Latency critical DMA read via PCIe
Dear All, I am currently developing a high throughput audio system which operates via PCIe tunneled into a USB4 interface. This include a custom FPGA based hardware and custom Audio DriverKit driver. While performing read operation via the hw DMA (that is a Host to Device transfer), I am noticing sparse latency spikes into the read transfers. Specifically, 4KB operations (which I assume including MRd + CpID) take normally from 5us to 40us to be completed, perfectly fine for my case. However, in some rare occasions, they can end up to 400us, which causes me overruns. The measurements have been carried out from the FPGA and they include the overall request and transfer time. While trying to tackle the problem, I'm investigating the possible power saving options and performance constraint methods at my disposal. I currently use these methods to mitigate the problem. ChangePowerState(kIOServicePowerCapabilityOn); SetPowerOverride(true); RequireMaxBusStall(kIOMaxBusStall25usec); CreatePMAssertion(kIOServicePMAssertionCPUBit | kIOServicePMAssertionForceFullWakeupBit, &ivars->PMAssertionID, false); The buffers are currently about 16MB, single segment, 16KB aligned and, of course, "prepared" for DMA. The system run for 3 hours without any overrun, but I'm not still fully convinced about its reliability. May someone provide me some comments on this? Are there profiling tools that I can use? Feel free to request me any required detail. The testing system is a MacBook Pro M2 Pro. Many Thanks and Best Regards Francesco

DCAppAttestService.isSupported always returns false on macOS 27
I've been implementing App Attest on macOS 27 following the WWDC 2026 Session 201 announcement. DCAppAttestService.shared.isSupported always returns false on my M4 Mac running macOS 27.0 (26A5368g), even with the correct entitlement and a valid provisioning profile. What I have set up (correctly, as far as I can tell) com.apple.developer.devicecheck.app-attest-opt-in capability enabled in the Developer Portal (value CDhash) Entitlement present in both the binary and the embedded provisioning profile Developer ID signed, ProvisionsAllDevices: true The problem DCAppAttestService.shared.isSupported returns false from every process type I tested: An EndpointSecurity system extension A launchd daemon A sandboxed app running in user session generateKey() fails with com.apple.devicecheck.error code 1 (featureUnsupported). Root cause? (from devicecheckd logs) I see these logs devicecheckd: [com.apple.devicecheck:aai] FeatureFlagsManager.m:35 Mac feature flag enabled { enabled=1 }. devicecheckd: (AppAttestInternal) [com.apple.appattest:secl] SecurityController.swift:44 Failed to fetch value for entitlement. { entitlement=com.apple.devicecheck.daemon-client } devicecheckd: (AppAttestInternal) [com.apple.appattest:aahl] AppAttestHandler.swift:48 Client connection is ineligible. { clientUUID=nil } So the feature IS active in macOS 27 (Mac feature flag enabled=1), but devicecheckd immediately rejects any connecting process that doesn't hold the private entitlement com.apple.devicecheck.daemon-client. What is com.apple.devicecheck.daemon-client? Searching public entitlement databases shows this entitlement exists on iOSbut no macOS binary appears to hold it in any public database. It's not available to third-party developers via the Developer Portal. This check in SecurityController.swift:44 appears to be new in this beta. Questions Is com.apple.devicecheck.daemon-client the correct mechanism for third-party developers to use App Attest on macOS 27, or is this an internal gating mechanism that will be replaced/removed before GM? Is App Attest on macOS 27 fully available to third-party developers in this seed, or is it still restricted to Apple-internal testing? Is there a different entitlement or provisioning capability that third-party developers should request to allow DCAppAttestService.isSupported to return true?

AppIntents and String catalog: how can we support both singular and plural forms for TypeDisplayRepresentation (used by DeleteIntent in the Shortcuts app for example)
Hello, I’m implementing the AppIntents framework in my app. I want to translate the TypeDisplayRepresentation that is used in the Shortcuts app UI like in a DeleteIntent (see my feedback about this: FB23451186 for more context). In the “Accelerating app interactions with App Intents” sample code we can see that this is done using a .stringsdict file, as follows for the “Trail” key (singular and plural): <key>Trail</key> <dict> <key>NSStringLocalizedFormatKey</key> <string>%#@VARIABLE@</string> <key>VARIABLE</key> <dict> <key>NSStringFormatSpecTypeKey</key> <string>NSStringPluralRuleType</string> <key>one</key> <string>Trail</string> <key>other</key> <string>Trails</string> </dict> </dict> I want to use a String catalog instead of a .stringsdict file because all my strings are in a String catalog. I tried to migrate the AppIntents.stringsdict file manually but it failed with an error: “An error occurred when migrating AppIntentsSampleApp/Resources/AppIntents.stringsdict: This stringsdict cannot be migrated: Missing required key 'NSStringFormatValueTypeKey' inside 'Trail' -> 'VARIABLE’” So I manually added a NSStringFormatValueTypeKey like this in the .stringsdict file: <key>Trail</key> <dict> <key>NSStringLocalizedFormatKey</key> <string>%#@VARIABLE@</string> <key>VARIABLE</key> <dict> <key>NSStringFormatSpecTypeKey</key> <string>NSStringPluralRuleType</string> <key>NSStringFormatValueTypeKey</key> <string>lld</string> <key>one</key> <string>Trail</string> <key>other</key> <string>Trails</string> </dict> </dict> And then I’ve been able to migrate the .stringsdict file into a String catalog. The string catalog looks like this after migration: "Trail" : { "extractionState" : "stale", "localizations" : { "en" : { "stringUnit" : { "state" : "translated", "value" : "%#@VARIABLE@" }, "substitutions" : { "VARIABLE" : { "formatSpecifier" : "lld", "variations" : { "plural" : { "one" : { "stringUnit" : { "state" : "translated", "value" : "Trail (Catalog)" } }, "other" : { "stringUnit" : { "state" : "translated", "value" : "Trails (Catalog)" } } } } } } } } This works, which is nice. But I tried to reproduce the same result by having a %#@VARIABLE@ in my LocalizedStringResource defaultValue like this: TypeDisplayRepresentation( name: LocalizedStringResource( "Flower", defaultValue: "%#@VARIABLE@", table: "AppIntents" ), numericFormat: LocalizedStringResource( "\(placeholder: .int) flower", table: "AppIntents" ) ) But the String catalog doesn’t support that apparently, I can’t get a “substitution” object in my catalog, so I have to manually do it using the source code which is not ideal and painful. Is there a way to support this kind of substitution with no actual plural token in the string as we can see for the %#@VARIABLE@ for Trail? Thank you, Regards, Axel

Hello everyone, face with the issue after I download the builds it stuck. Delivery tool: Manually via Xcode Organizer. The same issue also appears when uploading via Fastlane 2.233.1. The issue appeared after only a minor change: one localized string was modified. The important point is that this problem is not limited to this specific app. The same processing/delivery issue is currently affecting multiple apps (24). Apple support team knows about it, but, unfortunately more than 2 weeks, no reply. Could you please help with this? Maybe any advise? Thank you.

XCode - Apple Watch Connectivity
Hi Devs, I'm working with WatchOS for the first time and am having a frustrating time with Xcode to Watch, to say the least. I have a Series 9 dev watch and Xcode does not reliably connect to it. Spending 15-20 min per build/run attempt just trying to get xcode to find and connect to the watch. It WILL sometimes recognize and allow a build to run, the issue is I can't tell any reliable way to establish the connection. It drops after every build and leaves me at square zero. Current solution is some amount of force quitting, reconnecting iPhone to USBC, disconnecting watch to wifi and back on. Devices Window usually reads: Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters - swapping to some attempting to connect state that never (reliably resolves). Is this why no one builds for WatchOS? Hoping someone has pro tips on this.

How are the app reviews queued?
Hi, I was wondering about Apple's review queues. I have an app that in waiting for review for almost a week now but review time trackers claim average waiting times less than a day: https://www.runway.team/appreviewtimes My previous experience is also quite inconsistent, can you please shed some light on how things work internally? In this time I have done some improvements on the app that I was considering for the next update, should I cancel and re-submit?

StoreKit returns no in-app subscriptions on TestFlight despite correct App Store Connect configuration
Hello Applet, I’m experiencing an issue with StoreKit on a TestFlight build. My app uses auto-renewable subscriptions through StoreKit and RevenueCat. Configuration already verified: App installed through TestFlight (not debug). Bundle Identifier: com.ciborgu.vytalai Paid Applications agreement is active. In-App Purchase capability is enabled. Three auto-renewable subscriptions exist in App Store Connect. Product IDs match exactly between App Store Connect, RevenueCat and the application. RevenueCat initializes successfully. A Sandbox test account has been created. Tested on a physical iPhone. Device restarted and app reinstalled from TestFlight. VPN and iCloud Private Relay disabled. When attempting to purchase a subscription, the Apple payment sheet never appears. Our diagnostics indicate that StoreKit does not return any available products for the configured Product IDs, preventing the purchase sheet from opening. Expected Product IDs: vytalai_premium_monthly vytalai_premium_yearly vytalai_premium_yearly_intro Could you please verify if there is any issue with the App Store Connect configuration, StoreKit availability, or the processing state of these subscriptions on Apple’s side? If additional logs or diagnostics are required, I can provide them. Thank you. I have already contacted Apple Developer Support regarding this same issue. Previously, I was advised to schedule a technical support meeting. However, when I requested the meeting, my request was declined because of the subject of my issue, so I was unable to speak with an Apple engineer. Since I have now completed all the recommended troubleshooting and the issue still persists, I would greatly appreciate it if this case could be reviewed by the appropriate technical team or a StoreKit engineer. Thank you for your assistance.

watchOS 27 Developer Beta: App Switcher no longer accessible via double-press of Digital Crown
Hello, I updated my Apple Watch SE 3 (GPS + Cellular, 44 mm) to watchOS 27 Developer Beta (Build 24R5289n) and noticed what appears to be a change in the Digital Crown behavior. After the update: • A single press of the Digital Crown now shows fewer applications, which seems consistent with the changes announced for watchOS 27. • However, a double press of the Digital Crown no longer opens the App Switcher as it did previously. • As a result, I can no longer access the interface that allowed users to view recent apps and force-close applications by swiping them away. Before updating, double-pressing the Digital Crown opened the App Switcher and provided a way to close running apps. That functionality now appears to be missing. I would like to know whether: This is an intentional design change in watchOS 27. This is a known issue in the current Developer Beta. There is a new gesture or workflow for accessing recent apps and force-closing applications. Device: Apple Watch SE 3 (GPS + Cellular) 44 mm Aluminum Model: MEPJ4LW/A Software: watchOS 27.0 Developer Beta Build: 24R5289n The behavior is reproducible after restarting the watch. Thanks.

Timestamp counter heap always returns zero
Hi, I am trying to use a timestamp counter heap, but it always seems to report timestamp zero. Consider this example program: #include <Metal/Metal.h> #include <assert.h> int main(int argc, char *argv[]) { auto device = MTLCreateSystemDefaultDevice(); assert(device); auto descriptor = [MTL4CounterHeapDescriptor new]; [descriptor setType:MTL4CounterHeapTypeTimestamp]; [descriptor setCount:1]; auto heap = [device newCounterHeapWithDescriptor:descriptor error:nullptr]; assert(heap); [heap invalidateCounterRange:NSMakeRange(0, 1)]; auto command_buffer = [device newCommandBuffer]; assert(command_buffer); auto allocator = [device newCommandAllocator]; assert(allocator); [command_buffer beginCommandBufferWithAllocator:allocator]; auto encoder = [command_buffer computeCommandEncoder]; assert(encoder); [encoder writeTimestampWithGranularity:MTL4TimestampGranularityPrecise intoHeap:heap atIndex:0]; [encoder endEncoding]; [command_buffer endCommandBuffer]; auto queue = [device newMTL4CommandQueue]; assert(queue); auto event = [device newSharedEvent]; assert(event); [queue commit:&command_buffer count:1]; [queue signalEvent:event value:1]; [event waitUntilSignaledValue:1 timeoutMS:UINT64_MAX]; auto data = [heap resolveCounterRange:NSMakeRange(0, 1)]; printf("size %lu: %llu\n", data.length, *(uint64_t*)data.bytes); return 0; } Trying to compile and run: % clang++ -g -O0 -o test test.mm -framework Metal -framework Foundation && MTL_DEBUG_LAYER=1 ./test 2026-06-23 14:44:48.006 test[26472:1588857] Metal API Validation Enabled size 8: 0 I would have expected to receive size 8: [some random non-zero number] that number being a GPU timestamp of when the command was executed, but I always get zero. Does anybody have an idea of what I am doing wrong?

SwiftUI 6 AttributeGraph warnings in console
On a MacBook Air M4 running macOS Sequoia 15.7.7, the following tiny code does warn inside the Xcode 26.3. Here is the whole console output: === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 110216 === === AttributeGraph: cycle detected through attribute 110216 === === AttributeGraph: cycle detected through attribute 110284 === === AttributeGraph: cycle detected through attribute 110284 === === AttributeGraph: cycle detected through attribute 110216 === === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 109592 === === AttributeGraph: cycle detected through attribute 110216 === Here is the full code: import SwiftUI @main struct myApp: App { var body: some Scene { WindowGroup { BaseView() } } } struct BaseView: View { @State private var isWorking: Bool = false var body: some View { Button("Go") { Task { // AttributeGraph warnings await MainActor.run { isWorking = true } await MainActor.run { isWorking = false } // No warnings at all // DispatchQueue.main.async { isWorking = true } // DispatchQueue.main.async { isWorking = false } } } .disabled(isWorking) .padding() } } You can see with DispatchQueue.main.async {...}, warnings aren't there. After a few days struggling with different AI support (Claude, ChatGPT, Perplexity), I didn't find any way to fix my own code. This tiny code is just there to show the issue. I tested multiple workarounds without finding one that fits to my app context. Thanks in advance for your support.

Universal Links failing for some users but working for others
Hi, We are facing an issue where Universal Links are working for most users but failing for some of our clients. For affected users: Links open in Safari instead of the app, or Universal link routing does not work as expected For other users: The same links open the app correctly What we verified Associated Domains capability is configured correctly AASA file is valid and accessible App configuration and bundle ID mapping are correct AASA: https://www.gartner.com/apple-app-site-association Issue Since the problem is only affecting a subset of users, we are unable to: Reproduce the issue consistently Identify when or why the association breaks Ask Has anyone experienced: Universal Links failing only for certain users/devices? What are the possible causes and how can we debug or proactively identify the root cause in such cases? Any guidance would be helpful. Thanks!

Xcode Bug Installed Platforms
Hello, I’m using the latest version of Xcode, 26.6. I’m unable to permanently delete old installed iOS platform versions. I remove them from Xcode settings, and the deletion appears to complete successfully, but after rebooting my Mac they appear again, as if nothing had changed. Do you have any suggestions for how to remove them correctly and permanently?

Labels in toolbar menu get wrapped when upgrading from iOS 18 to 26
When upgrading an app from iOS 18 to iOS 26, some labels in a toolbar menu get wrapped unexpectedly. The issue can be reproduced through the sample below, which contains this label : "Envoyer une réaction" On iPhone with iOS 18, the label is displayed on 1 line. But on iPhone with iOS 26, the label is displayed on 2 lines. No improvement was obtained through these modifiers : .lineLimit, .frame and .fixedSize . . How to avoid this unnecessary label wrapping that disrupts the readability ? . . import SwiftUI struct SampleView: View { var body: some View { NavigationStack { Color.clear .toolbar { ToolbarItem { Menu { Button(action: {}) { Label("Envoyer une réaction", systemImage: "envelope") } } label: { Image(systemName: "ellipsis") } } } } } } #Preview { SampleView() }

M4 Mac Mini: Xcode generates private keys with wrong label - codesigning impossible
M4 Mac Mini: Xcode generates private keys with wrong label - codesigning impossible Background This is a follow up to my November 2024 thread "Keychain issues after installing backup on new Mac" which was closed because I had a temporary workaround. That workaround using my wife's MacBook Air for signing is not sustainable. I used AI assistance to determine the root cause. My DTS case 102877839447 is open but has not yet been forwarded to a DTS engineer. Environment Mac Mini M4, macOS 15.4.1 (Build 25E253) Xcode 26.4.1 (17E202) Team ID: Q23726668V (Computerade Products) Working comparison machine: MacBook Air, macOS 15.3 Precise Bug — Reproducible Every Time Every time Xcode generates a new certificate and key pair on my Mac Mini: Certificate: Apple Development: Michael Birch (9KD5TCGGHG) ✅ Private key: Apple Development: Michael Birch (Computerade Products) ❌ The key uses the organization name instead of the certificate identifier. They never pair as a valid codesigning identity. security find-identity -v -p codesigning always returns 0 valid identities. Cryptographic Evidence The internal application labels confirm the keys are cryptographically unrelated to their certificates: Key internal application label: 53C26EB056997276B5E938258D00665ACABD1F0F Certificate public key hash: 57cd1af4a9162f26b1a6d750e05a63a2166b75ff These do not match ❌ Confirmed Eliminated As Causes Keychain search list corruption — found and fixed Partition list — set correctly Access control — set to allow all applications Full Disk Access — granted to Xcode Xcode caches and preferences — completely cleared Login keychain — completely reset Orphaned certificates and keys — all removed SIP enabled, system fully up to date Valid P12 Import Also Fails A p12 exported from the working MacBook Air and cryptographically verified as a matched pair also fails on the Mac Mini: security import returns MAC verification failed Keychain Access import returns OSStatus -2 Importing certificate and key separately as PEM files succeeds but they are not recognized as a valid identity pair despite matching application labels A3F3F193B7896DA9055353F59AB450778CB09AE7 Question Is there a known issue with M4 Mac Mini keychain infrastructure where private keys are generated with incorrect internal application labels? Is there a lower level diagnostic or fix beyond what the security command provides? The problem is specific to my Mac Mini M4 and persisted thru more than a year of Mac OS and xCode updates.

PHPickerViewController: UI rendering failure and data retrieval errors on iOS 17 & 26.4
Description: I am encountering critical issues with PHPickerViewController using the "Zero-Permission" configuration. The behavior differs significantly between iOS 17 and iOS 26.4, but both prevent successful image selection. Observed Behaviors: On iOS 26.4 (iPhone 17 Pro Max): The PHPicker UI fails to render the photo grid entirely. Upon initialization, the system UI displays an "Unable to load photo" alert, preventing users from even viewing or selecting images. On iOS 17: The picker UI loads, but after the user selects an image and adds it, the subsequent itemProvider.loadObject call consistently fails, returning an error and preventing our app from retrieving the image data. Current Implementation: var config = PHPickerConfiguration() config.filter = .images config.selectionLimit = pickLimit // Problematic logic: if ABTestManager.shared.isPHPickerCurrent { config.preferredAssetRepresentationMode = .current } let pickerVC = PHPickerViewController(configuration: config) pickerVC.delegate = self user device Images: What I have tested: I have been using preferredAssetRepresentationMode = .current in my AB tests. I have not yet tested .compatible mode, as my application logic requires access to high-fidelity assets. However, the current behavior suggests a regression or a fundamental incompatibility with how the system handles image containers for high-end hardware (e.g., iPhone 17 Pro Max) in the out-of-process picker. Supporting Documentation: Minimal Reproducible Project: [Attached] Logs: [Attached sysdiagnose logs] My Questions: Is the "Unable to load photo" UI failure on iOS 26.4 a known limitation for certain high-resolution asset types when using .current mode? Are there specific handling requirements for NSItemProvider when the system fails to resolve the image data in .current mode on older iOS 17 devices? Given that these failures occur in a "Zero-Permission" context, are there specific metadata or image processing constraints I should be aware of to prevent the picker from entering a "failed" state?

iOS build stuck in "Waiting for Review" — macOS/tvOS of same version already approved (App ID 6763137740)
Hello App Review Team, I'm hoping someone can take a manual look or point me in the right direction. The iOS build of my app has been sitting in "Waiting for Review" with no status change, while the macOS and tvOS builds of the exact same version have already been reviewed and released. App: VixioTV - IPTV & M3U Player App ID: 6763137740 Platform: iOS (iPhone/iPad) Current status: Waiting for Review Most recent submission: [June 24, 2026] Time in queue: ~24 days with no status change Related case IDs: [your expedited review / Developer Support case numbers] Context I'd like to share proactively: This is an update to an app that is ALREADY LIVE on the App Store (current iOS version 1.2). It is not a new app. The macOS and tvOS versions of this same update have already passed review and are live — only the iOS build is stuck. VixioTV is a bring-your-own-content player: it provides no broadcasts or content of its own. Users connect their own IPTV subscription (API credentials or an M3U URL). There is no registration, subscription, or content sale inside the app. I have submitted expedited review requests and contacted Developer Support, but I've only received generic/automated replies with no change in status. I would really appreciate it if someone could: Confirm whether there is any issue with the build, metadata, agreements, or account that requires action on my side. Indicate whether this is queue congestion or a submission-specific hold. If possible, escalate or trigger a manual review. Thank you very much for your help. Selcuk Kaymaz

StoreKit 2: New offer code NOT in Transaction.currentEntitlements()
This is production issue with a user completely stuck: User entered an offer code for 1 year free --> validated under iOS > Apple Account > subscriptions: it correctly shows a 1 year free trial But the transaction is not listed in his Transaction.currentEntitlements() Even after a restore (App.sync()) The Apple Account has always been the same (no mix) This is with the new offer codes introduced in 2026 Also, user wanted to pay the subscription himself in order to unlock the situation, he cannot because of the 'active' offer. Tried giving him another code, but it's refused by the system because there is only one active. Urgent help would be greatly appreciated. func readEntitlements(fromDeferredTransaction: Bool = false) async { var purchasedNonConsumables: [Product] = [] var purchasedSubscriptions: [Product] = [] var purchasedNonRenewableSubscriptions: [Product] = [] var activeSubTransactions: [Transaction] = [] //Iterate through all of the user's purchased products. for await result in Transaction.currentEntitlements { // currentEntitlements is a StoreKit2 useful feature that only gives us the relevant transactions (not the old & expired ones) do { //Check whether the transaction is verified. If it isn’t, catch `failedVerification` error. let transaction = try checkVerified(result) //Check the `productType` of the transaction and get the corresponding product from the store. switch transaction.productType { case .nonConsumable: if let nc = availableNonConsumables.first(where: { $0.id == transaction.productID }) { purchasedNonConsumables.append(nc) } case .nonRenewable: if let nonRenewable = availableNonRenewableSubscriptions.first(where: { $0.id == transaction.productID }) { let currentDate = Date() let expirationDate = Calendar(identifier: .gregorian).date(byAdding: DateComponents(year: 1), to: transaction.purchaseDate)! if currentDate < expirationDate { purchasedNonRenewableSubscriptions.append(nonRenewable) } } case .autoRenewable: if transaction.revocationDate == nil { activeSubTransactions.append(transaction) } if let subscription = availableSubscriptions.first(where: { $0.id == transaction.productID }) { DLog("Found valid entitlement. Subscription with exp date = \(String(describing: transaction.expirationDate))") purchasedSubscriptions.append(subscription) } else { DLog("Entitled to \(transaction.productID) but its Product is not loaded (product fetch failed/incomplete). Access will be granted from the transaction.") } default: break } } catch { print() } } //Update the store information with the purchased products. self.purchasedNonConsumables = purchasedNonConsumables self.purchasedNonRenewableSubscriptions = purchasedNonRenewableSubscriptions //Update the store information with auto-renewable subscription products. self.purchasedSubscriptions = purchasedSubscriptions //Authoritative entitlement transactions (independent of the product fetch succeeding). self.activeSubTransactions = activeSubTransactions subscriptionGroupStatus = try? await availableSubscriptions.first?.subscription?.status.first?.state // Callback IAPManager.shared.updateProStatus(isSureThatUserIsOnline: fromDeferredTransaction) }

Single Build / Archive for iOS and Catalyst Build
So I am adding Catalyst support to my iOS app. I went through and updated my code and Build Settings to add Catalyst support. I can build for any iOS build or macOS build. I went into App Store Connect and then added a macOS build. I am not able to do a single build and archive that uploads a build for both macOS and iOS. I can do a build and archive for "Any iOS Device (arm64)" and it shows up in the iOS test flight. I can do a build and archive for "Any Mac (Mac Catalyst, arm64, x86_64) and it shows in the macOS test flight. Maybe I'm making a bad assumption ( I could not find any documentation on it) but I assumed Catalyst was a single build and archive that showed up in BOTH macOS and iOS sections. The build settings seem to imply the build is good for a single build and archive process. I want this to be a universal app and my assumption doing it that way would keep everything in sync when you push to the App Store. You can already download the app through the App Store but it is a version of the iPad app. I was hoping to make it more native and available in the Mac App Store without the iPhone/iPad app option. Am I making bad assumptions? Will I just have to do two Build and Archives for every build? I just want to make sure I'm doing this correctly and the best way.

Latency critical DMA read via PCIe
Dear All, I am currently developing a high throughput audio system which operates via PCIe tunneled into a USB4 interface. This include a custom FPGA based hardware and custom Audio DriverKit driver. While performing read operation via the hw DMA (that is a Host to Device transfer), I am noticing sparse latency spikes into the read transfers. Specifically, 4KB operations (which I assume including MRd + CpID) take normally from 5us to 40us to be completed, perfectly fine for my case. However, in some rare occasions, they can end up to 400us, which causes me overruns. The measurements have been carried out from the FPGA and they include the overall request and transfer time. While trying to tackle the problem, I'm investigating the possible power saving options and performance constraint methods at my disposal. I currently use these methods to mitigate the problem. ChangePowerState(kIOServicePowerCapabilityOn); SetPowerOverride(true); RequireMaxBusStall(kIOMaxBusStall25usec); CreatePMAssertion(kIOServicePMAssertionCPUBit | kIOServicePMAssertionForceFullWakeupBit, &ivars->PMAssertionID, false); The buffers are currently about 16MB, single segment, 16KB aligned and, of course, "prepared" for DMA. The system run for 3 hours without any overrun, but I'm not still fully convinced about its reliability. May someone provide me some comments on this? Are there profiling tools that I can use? Feel free to request me any required detail. The testing system is a MacBook Pro M2 Pro. Many Thanks and Best Regards Francesco

DCAppAttestService.isSupported always returns false on macOS 27
I've been implementing App Attest on macOS 27 following the WWDC 2026 Session 201 announcement. DCAppAttestService.shared.isSupported always returns false on my M4 Mac running macOS 27.0 (26A5368g), even with the correct entitlement and a valid provisioning profile. What I have set up (correctly, as far as I can tell) com.apple.developer.devicecheck.app-attest-opt-in capability enabled in the Developer Portal (value CDhash) Entitlement present in both the binary and the embedded provisioning profile Developer ID signed, ProvisionsAllDevices: true The problem DCAppAttestService.shared.isSupported returns false from every process type I tested: An EndpointSecurity system extension A launchd daemon A sandboxed app running in user session generateKey() fails with com.apple.devicecheck.error code 1 (featureUnsupported). Root cause? (from devicecheckd logs) I see these logs devicecheckd: [com.apple.devicecheck:aai] FeatureFlagsManager.m:35 Mac feature flag enabled { enabled=1 }. devicecheckd: (AppAttestInternal) [com.apple.appattest:secl] SecurityController.swift:44 Failed to fetch value for entitlement. { entitlement=com.apple.devicecheck.daemon-client } devicecheckd: (AppAttestInternal) [com.apple.appattest:aahl] AppAttestHandler.swift:48 Client connection is ineligible. { clientUUID=nil } So the feature IS active in macOS 27 (Mac feature flag enabled=1), but devicecheckd immediately rejects any connecting process that doesn't hold the private entitlement com.apple.devicecheck.daemon-client. What is com.apple.devicecheck.daemon-client? Searching public entitlement databases shows this entitlement exists on iOSbut no macOS binary appears to hold it in any public database. It's not available to third-party developers via the Developer Portal. This check in SecurityController.swift:44 appears to be new in this beta. Questions Is com.apple.devicecheck.daemon-client the correct mechanism for third-party developers to use App Attest on macOS 27, or is this an internal gating mechanism that will be replaced/removed before GM? Is App Attest on macOS 27 fully available to third-party developers in this seed, or is it still restricted to Apple-internal testing? Is there a different entitlement or provisioning capability that third-party developers should request to allow DCAppAttestService.isSupported to return true?

AppIntents and String catalog: how can we support both singular and plural forms for TypeDisplayRepresentation (used by DeleteIntent in the Shortcuts app for example)
Hello, I’m implementing the AppIntents framework in my app. I want to translate the TypeDisplayRepresentation that is used in the Shortcuts app UI like in a DeleteIntent (see my feedback about this: FB23451186 for more context). In the “Accelerating app interactions with App Intents” sample code we can see that this is done using a .stringsdict file, as follows for the “Trail” key (singular and plural): <key>Trail</key> <dict> <key>NSStringLocalizedFormatKey</key> <string>%#@VARIABLE@</string> <key>VARIABLE</key> <dict> <key>NSStringFormatSpecTypeKey</key> <string>NSStringPluralRuleType</string> <key>one</key> <string>Trail</string> <key>other</key> <string>Trails</string> </dict> </dict> I want to use a String catalog instead of a .stringsdict file because all my strings are in a String catalog. I tried to migrate the AppIntents.stringsdict file manually but it failed with an error: “An error occurred when migrating AppIntentsSampleApp/Resources/AppIntents.stringsdict: This stringsdict cannot be migrated: Missing required key 'NSStringFormatValueTypeKey' inside 'Trail' -> 'VARIABLE’” So I manually added a NSStringFormatValueTypeKey like this in the .stringsdict file: <key>Trail</key> <dict> <key>NSStringLocalizedFormatKey</key> <string>%#@VARIABLE@</string> <key>VARIABLE</key> <dict> <key>NSStringFormatSpecTypeKey</key> <string>NSStringPluralRuleType</string> <key>NSStringFormatValueTypeKey</key> <string>lld</string> <key>one</key> <string>Trail</string> <key>other</key> <string>Trails</string> </dict> </dict> And then I’ve been able to migrate the .stringsdict file into a String catalog. The string catalog looks like this after migration: "Trail" : { "extractionState" : "stale", "localizations" : { "en" : { "stringUnit" : { "state" : "translated", "value" : "%#@VARIABLE@" }, "substitutions" : { "VARIABLE" : { "formatSpecifier" : "lld", "variations" : { "plural" : { "one" : { "stringUnit" : { "state" : "translated", "value" : "Trail (Catalog)" } }, "other" : { "stringUnit" : { "state" : "translated", "value" : "Trails (Catalog)" } } } } } } } } This works, which is nice. But I tried to reproduce the same result by having a %#@VARIABLE@ in my LocalizedStringResource defaultValue like this: TypeDisplayRepresentation( name: LocalizedStringResource( "Flower", defaultValue: "%#@VARIABLE@", table: "AppIntents" ), numericFormat: LocalizedStringResource( "\(placeholder: .int) flower", table: "AppIntents" ) ) But the String catalog doesn’t support that apparently, I can’t get a “substitution” object in my catalog, so I have to manually do it using the source code which is not ideal and painful. Is there a way to support this kind of substitution with no actual plural token in the string as we can see for the %#@VARIABLE@ for Trail? Thank you, Regards, Axel

Build stuck in "Processing" status for 2 weeks
Hello everyone, face with the issue after I download the builds it stuck. Delivery tool: Manually via Xcode Organizer. The same issue also appears when uploading via Fastlane 2.233.1. The issue appeared after only a minor change: one localized string was modified. The important point is that this problem is not limited to this specific app. The same processing/delivery issue is currently affecting multiple apps (24). Apple support team knows about it, but, unfortunately more than 2 weeks, no reply. Could you please help with this? Maybe any advise? Thank you.

XCode - Apple Watch Connectivity
Hi Devs, I'm working with WatchOS for the first time and am having a frustrating time with Xcode to Watch, to say the least. I have a Series 9 dev watch and Xcode does not reliably connect to it. Spending 15-20 min per build/run attempt just trying to get xcode to find and connect to the watch. It WILL sometimes recognize and allow a build to run, the issue is I can't tell any reliable way to establish the connection. It drops after every build and leaves me at square zero. Current solution is some amount of force quitting, reconnecting iPhone to USBC, disconnecting watch to wifi and back on. Devices Window usually reads: Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters - swapping to some attempting to connect state that never (reliably resolves). Is this why no one builds for WatchOS? Hoping someone has pro tips on this.
