Overview

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.

After updating to Xcode 26.5 Xcode crashes when I try to open my project. Directly before update everything was fine... Not using Beta-Software.. only stable versions What can I do? Will there be an update fixing this bug? `Application Specific Information: abort() called Application Specific Signatures: NSInternalInconsistencyException Application Specific Backtrace 0: 0 CoreFoundation 0x0000000186e711c0 __exceptionPreprocess + 176 1 DVTFoundation 0x000000010578a20c DVTFailureHintExceptionPreprocessor + 388 2 libobjc.A.dylib 0x00000001868fa91c objc_exception_throw + 88 3 Foundation 0x000000018868f498 -[NSFileWrapper regularFileContents] + 436 4 IDEStoreKitCore 0x000000030e002b20 $s15IDEStoreKitCore0aB13ConfigurationC4FileV17configurationData10Foundation0G0Vvg + 440 5 IDEStoreKitCore 0x000000030e001da0 $s15IDEStoreKitCore0aB13ConfigurationC13configuration3forACSo13NSFileWrapperC_tKFZ + 304 6 IDEStoreKitCore 0x000000030e003b0c $s15IDEStoreKitCore0aB13ConfigurationC13configuration2atAC10Foundation3URLV_tKFZ + 148 7 IDEStoreKitEditor 0x000000030e792ecc $s17IDEStoreKitEditor0aB20TextFragmentProviderC12generateSeed3for17completionHandlerySo11DVTFilePathC_ySo07IDETextefH0_pSg_s5Error_pSgtctFZ06$sSo27nefh28_pSgSo7NSErrorCSgIeyByy_ABs5o2_pR8Ieggg_TRAJSo0T0CSgIeyByy_Tf1ncn_nTf4ndg_n + 152 8 IDEStoreKitEditor 0x000000030e7922fc $s17IDEStoreKitEditor0aB20TextFragmentProviderC12generateSeed3for17completionHandlerySo11DVTFilePathC_ySo07IDETextefH0_pSg_s5Error_pSgtctFZTo + 52 9 IDEFoundation 0x000000010c922318 __113+[IDETextFragmentIndex runProvider:forFilePath:explicitFileDataType:initialTimestamp:priority:completionHandler:]_block_invoke + 204 10 DVTFoundation 0x00000001058a0638 __51-[DVTThrottledConcurrentQueue processQueueIfNeeded]_block_invoke + 80 11 DVTFoundation 0x0000000105892bd0 DVT_CALLING_CLIENT_BLOCK + 16 12 DVTFoundation 0x0000000105893548 __DVTDispatchAsync_block_invoke + 152 13 libdispatch.dylib 0x0000000186b8aa28 _dispatch_call_block_and_release + 32 14 libdispatch.dylib 0x0000000186ba44b0 _dispatch_client_callout + 16 15 libdispatch.dylib 0x0000000186b8f1c8 _dispatch_continuation_pop + 596 16 libdispatch.dylib 0x0000000186b8e844 _dispatch_async_redirect_invoke + 580 17 libdispatch.dylib 0x0000000186b9c980 _dispatch_root_queue_drain + 360 18 libdispatch.dylib 0x0000000186b9d120 _dispatch_worker_thread2 + 184 19 libsystem_pthread.dylib 0x0000000186d41e84 _pthread_wqthread + 232 20 libsystem_pthread.dylib 0x0000000186d40c10 start_wqthread + 8`

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

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?

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.

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.

Hi everyone, I’m having an issue where my TestFlight build cannot load auto-renewable subscription products from App Store Connect. The app is built with Flutter and uses StoreKit 2 through an in-app purchase implementation. The same subscription system works correctly on Google Play Billing and returns product details/prices there, but on iOS StoreKit returns no subscription products. I tested this on a real iPhone installed from TestFlight, not from Xcode debug and not using a local StoreKit configuration. The app requests four auto-renewable subscription product IDs. The IDs in code exactly match the product IDs in App Store Connect. The app diagnostics show: Platform: iOS StoreKit mode: StoreKit 2 Store available: true Requested IDs: 4 subscription product IDs Returned IDs: none Missing IDs: all requested product IDs Error source: app_store Error code: storekit_no_response Error message: StoreKit: Failed to get response from platform. Store note: The store accepted the query, but did not return details for these product IDs. Things I have already checked: Product IDs match exactly between Flutter code and App Store Connect Bundle ID matches the App Store Connect app record In-App Purchase capability is enabled Subscriptions are in one subscription group Subscription availability is set for all countries/regions The TestFlight build is installed on a real device Local StoreKit configuration was removed StoreKit reports store availability as true App Store Connect / In-App Purchase keys are configured for backend verification The same product-loading flow works on Google Play The current App Store Connect status for the subscriptions is: Subscriptions: Ready to Submit / Ready for Review Localizations: Prepare for Submission Also, the bank information is not submitted yet. My question is: can StoreKit in TestFlight return subscription product details while the first auto-renewable subscriptions are still only “Ready to Submit” and have not yet been submitted with an app version for review? Or will StoreKit return no products until: The first subscriptions are attached to an app version and submitted for review Subscription localizations are fully prepared/submitted Paid agreements, tax, and banking are fully completed Since StoreKit is available and accepts the product query, but returns zero products, I’m trying to understand whether this is expected App Store Connect behavior or if there is another configuration issue I should check. Thanks.

Our vehicle digital key app uses CBCentralManagerOptionRestoreIdentifierKey and bluetooth-central background mode to maintain BLE connections with cars. We want to confirm: if the app is actively connected to a BLE vehicle peripheral and then terminated by system memory reclamation (not user force-quit), will iOS automatically relaunch the app via Bluetooth State Restoration when the peripheral sends notifications or re-advertises? Also please list all mandatory conditions to trigger such Bluetooth-based background relaunch after system termination, and clarify whether this pure-BLE relaunch channel works independently apart from iBeacon location-triggered cold launch for our terminated app on iOS 26 without AccessorySetupKit. Best regards

On this talk: Bring an LLM provider to the Foundation Models framework URL: https://developer.apple.com/videos/play/wwdc2026/339/ on the coding examples a very peculiar framework is shown: import MLXFoundationModels However I am not able to find it nowhere, there is even a code section with this framework as part of an example. Where is this framework, there are no BETA branches on the MLX framework either. Thanks!

Heya, I recently submitted two app updates for two apps, one got reviewed within the hour. The other is waiting for 5 days. The second one is more complex, but also changed the name (core name stayed the same, just added some text) and description, does that effect the que or review? As it's kinda weird that one takes 1h and the other is still waiting while both are submitted within 6h of each other.

Hello everyone, I recently enrolled in the Apple Developer Program as an Individual developer, and my enrollment is still being processed. My enrollment was submitted on June 17, 2026, and I currently have an open support case (102921992970) with Apple Developer Support. Unlike some payment-related issues discussed here, I have not been charged yet, and no payment has been processed from my card. My enrollment simply remains in a pending/processing state. At the moment, I have not received any requests for additional information or documentation. My support case remains open, but I have not yet received an update regarding the status of the review. I wanted to ask if anyone else has experienced a similar delay recently. How long did your enrollment take to be approved? Were you contacted for additional verification? Is it normal for enrollment review to take more than a few business days before payment is processed? Any insights or experiences would be greatly appreciated. Thank you. Kind regards, Famous Macaulay

My Non-Consumable IAP was rejected with Guideline 3.1.1 and now has status ‘Developer Action Required’. The problem: On the version page in App Store Connect, the ‘In-App Purchases and Subscriptions’ section does not appear at the bottom. I cannot link the IAP to a new version submission. Every time I submit a new binary, Apple approves the app version but rejects the IAP afterward — even though I have no way to attach it to the version in the first place. This seems to be a circular issue: the IAP doesn’t appear on the version page because of its current status, but the only way to fix the status is to submit it with a new version. Has anyone experienced this and found a solution? Any help appreciated!​​​​​​​​​​​​​​​​

Hi, I would like to dipslay resource monitoring graph of CPU, Memory & Network of a running VM with Virtuization Framework. How can i do it with Swift? Is there a way we can do it without the need of guest agents.

In Xcode project > Build Settings > Swift Compiler - Concurrency. When we have those settings : Approachable Concurrency - Yes Default Actor Isolation - MainActor A sendable struct without @Actor annotation will be stuck to @MainActor. But if we have a sendable struct, by principle, it should be used across Actors. To remediate the situation, we had to prefix the struct with nonisolated keyword. The setting "Default Actor Isolation - MainActor" should not add @MainActor to Sendables. Problem describe in : FB23264607

Transitions inside ScreenTime Report is not working if phone locked when app is opened. It is starts working only after terminate and open the app.

Hello, I'm looking for advice because my app update appears to be stuck in "Waiting for Review." Submission date: June 11, 2026 Status: Waiting for Review (it has never changed to "In Review") Type: Update to an existing app (not a new app) This update does not introduce: new subscriptions or paywalls, new payment methods, major changes to the app's business model. I've already: Submitted an App Review Support request. Submitted an Expedited Review Request. Waited for a response, but I haven't received any reply. I've also verified that there are no outstanding agreements or obvious issues in App Store Connect. Has anyone experienced a similar situation recently? If so: Did your submission eventually move into review on its own? Did you have to withdraw and resubmit? Is there another way to contact the App Review team when support requests receive no response? If an Apple staff member sees this, I'd appreciate it if you could check whether my submission or support case may be stuck. Thank you.

We develop a healthcare emergency-alerting app with a native watchOS companion app. We've hit a network routing issue on watchOS that we cannot work around with any public API, and it breaks a safety-critical flow (triggering an emergency alarm from the watch). Environment watchOS 26.5 on Apple Watch SE3, paired with iPhone SE 2nd Gen on iOS 26.5 Watch app deployment target: watchOS 9.0 Plain URLSession (async/await), default configuration plus waitsForConnectivity = false, allowsExpensiveNetworkAccess = true, allowsConstrainedNetworkAccess = true HTTPS to our own backend (valid public TLS certificate, no pinning) Steps to reproduce Pair the watch with the iPhone. Both on the same known Wi-Fi network. On the iPhone: turn OFF Wi-Fi and cellular data. Keep Bluetooth ON. The watch remains connected to its known Wi-Fi network (or would be, if the system brought the radio up). Trigger any HTTPS request from the watch app (foreground). Expected Since the companion iPhone has no internet, the watch should satisfy the request over its own Wi-Fi. Actual The request is routed through the companion link (ipsec1, "companion preference: prefer" in the logs) and fails after the TLS handshake dies inside the tunnel: Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made." _kCFStreamErrorDomainKey=3, _kCFStreamErrorCodeKey=-9816 (errSSLClosedNoNotify) The watch never fails over to its own Wi-Fi, no matter how many times we retry or how long we wait. The same request succeeds within seconds if the user disables Bluetooth on the iPhone (watch then joins Wi-Fi directly), or restores the iPhone's internet. What we already tried waitsForConnectivity = true doesn't help; a path exists (the tunnel), it just doesn't work. Fresh URLSession per retry, backoff retries still routed via the tunnel. Per TN3135 we understand low-level networking is not available to a normal app: we prototyped NWConnection with prohibitedInterfaceTypes = [.other], and indeed on device NWPathMonitor stays .unsatisfied even when the watch has working Wi-Fi, exactly as TN3135 describes. So Network framework is not an escape hatch for us, and we are not looking to abuse the audio-streaming/CallKit carve-outs. Questions Is the companion-preferred routing supposed to fail over to the watch's own Wi-Fi when the iPhone is reachable over Bluetooth but has no internet? If yes, on what timescale, and is there anything an app can do to help the system notice the dead path sooner? Is there ANY supported way for a foreground watchOS app to express "do not use the companion link for this request"? We found only the private _companionProxyPreference SPI, which we obviously can't ship. If the answer to both is "no", what is the recommended pattern for safety-critical requests in this state is failing fast and instructing the user to disable iPhone Bluetooth really the intended UX? Related earlier reports of the same behavior: https://developer.apple.com/forums/thread/759321 https://developer.apple.com/forums/thread/107964

I have paid the enrollment tax with a debit card from my business parter. My account still not enrolled at development program. I have 2 tickets at apple support since 06/23 and nothing was done. Any suggestions?

Hi everyone, I've submitted a Feedback request (FB23469644) asking to introduce a generic Transportation Journey schema for App Intents. At the moment, there doesn't seem to be a way to donate structured public transportation trips (train, flight, bus, ferry, etc.) to Siri's semantic index. While many travel apps already have rich journey data, there is no common semantic model that represents: Multi-leg journeys Departure and arrival stations/airports/stops Platforms, tracks, gates, terminals Scheduled and real-time departure/arrival information Delays and cancellations Ticket and reservation information This seems like a natural addition to the existing App Intents schemas and would enable Siri, Spotlight, and Apple Intelligence to better understand upcoming journeys across all transportation providers. If you're building a travel or mobility app and have encountered the same limitation, I'd appreciate hearing your thoughts. Any idea if the old Siri event suggestion API gets is indexed by Siri Semantic Index / Siri AI?
