AWS SNS False Success Delivery
We operate a social network application, SportsYou with over 3 million monthly active users and are experiencing significant issues with push notification delivery through APNs. We have a large number of users reporting they are not receiving push notifications. Our infrastructure uses AWS SNS integrated with APNs to deliver notifications. However, AWS CloudWatch consistently reports successful delivery (Success response), even though users confirm they never received the notifications. Because we receive success responses from AWS SNS, our system does not attempt to recreate or refresh the device endpoints. This leaves us unable to detect or recover from these delivery failures automatically. This issue is widespread and inconsistent. It affects users across multiple variables including different iOS versions, different device models, and different versions of our application. We cannot identify a clear pattern that would help us isolate the root cause. With millions of active users, even a small percentage of delivery failures represents thousands of users experiencing a degraded service. This is significantly impacting user engagement and satisfaction. We need guidance on how to properly diagnose this issue and ensure reliable notification delivery to our users. Specifically, we'd like to understand why we're receiving success responses when notifications aren't being delivered, and what steps we can take to detect and prevent these failures.

WeatherKit JWT Auth error for SOME customer devices
We have a subscription WeatherKit app which has been on the App Store since December 2023. I am getting intermittent JWT auth failures on customer devices. In the great majority of cases, the request succeeds, but sometimes it fails, and sometimes it fails and never recovers. I’m working with a customer right now who is unable to get any weather data at all, and the logs he sends me show WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 The app uses the WeatherKit SDK (we are not using the REST API directly). We know we have the project setup as it has been working since launch, and I can verify weatherkit using security cms -D -i embedded.mobileprovision It it not a problem with the specific query, since I can get data for the dates and locations they are requesting. I can’t replicate the problem on my test devices. In case there is a rate limit issue: this app is a bit unusual and downloads an unusual amount of data at once using multiple queries in parallel using a TaskGroup. When the user creates a location, the app downloads a 10 day block of weather (7 days in the past + 3 day forecast) using WeatherService.shared.weather( for: location, including: WeatherQuery.daily( startDate: startDate, endDate: endDate ), WeatherQuery.hourly( startDate: startDate, endDate: endDate ) ) It also downloads about 2 months of daily precipitation data using multiple parallel calls to dailySummary in 10 day blocks: WeatherService.shared.dailySummary( for: location, forDaysIn: DateInterval(start: startDate, end: endDate), including: .precipitation ) In almost every case, including on my test devices, this works. But some users get WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors error 2 on every request. The two users yesterday that had this problem were both on iOS 18.5 for what that's worth, though the app supports 17.2+ Is anyone else seeing this? And can anyone suggest anything else to explore? It's obviously a terrible experience for customers who pay for the service and are unable to get any data. I did submit this info to Apple as FB18276275

Home App Intermittent Hub Not Responding Bug
I'm encountering a strange behavior with one of my home's on Home app while I'm off network. When I launch the app it indicates that the hub is not responding and all of my devices are unavailable. However, on the menu bar at the bottom if I switch to "Automation" and back to "Home" the pop-up goes away and my devices are accessible again (sometimes this take a few attempts). Siri is also able to consistently control my devices without an issue. The same behavior occurs with Home app on other devices (e.g. Mac) and with other members that have access to the household. 3rd party HomeKit app like "Controller" does not have an issue. This issue began with iOS 26 and I haven't had much luck resolving the issue. I already tried rebooting everything, including removing and re-adding an Apple TV (home hub). I have other homes shared with me in Home App with similar network/environment that are still working. The home I'm having issues has the most number of devices though (over 100+).

“Payment method is not available” message in Sandbox subscription testing (StoreKit 2)
I’m implementing App Store subscriptions using StoreKit 2 and testing in the Sandbox environment. Until about a week ago everything worked fine, but recently the Settings > Subscriptions screen shows this message for my test account: “Your current payment method is not available.” The behavior: • Using a Sandbox tester account (not a production Apple ID) • Purchase flow works successfully — the transaction completes, and I receive server notifications • However, the system Settings app still displays that message under the subscription entry • No code changes were made since it last worked Questions: 1. What exactly does this message mean in the Sandbox environment? 2. Could this be related to any Apple system issue or recent backend update? 3. Has anyone else seen the same behavior in recent days? Environment: • Xcode 15.4 • iOS 17.5 (physical device) • StoreKit 2 / Swift 5.10 • Sandbox tester (Japan region) Thanks in advance for any insights or confirmations from others who are testing subscriptions in Sandbox!

Tokens change without reason after updating to iOS 17.5.1
Some of our users encounter an issue after updating their iPhone/iPad to iOS 17.5.1. The tokens passed in the Shield Configuration extension don't match the tokens they selected in my app using the FamilyPicker before updating to iOS 17.5.1. It seems the tokens changed for no reason. My app can't match the token from the ShieldConfigurationDataSource to any tokens stored on my end, causing my shield screens to turn blank. The same applies to tokens in the Device Activity Report extension. The only workaround I've found is to tell affected users to unselect and reselect apps and websites to block in my app. This gets them new tokens from the FamilyActivityPicker, which solves the issue. However, for some users, the bug reoccurs a few days later. Tokens seem to change again, causing the same issue in the Shield Configuration extension. I am not able to reproduce the issue on my test devices so I have no sysdiagnose to attach. However, this issue is affecting other screen time apps: https://developer.apple.com/forums/thread/732845 https://forums.developer.apple.com/forums/thread/756440 FB14082790 FB14111223 A change in iOS 17.5.1 must have triggered this behaviour. Could an Apple engineer give us any updates on this?

Open Parent App From ShieldActionDelegate
Hello, I’m building an app that helps people spend less time on social media apps. For that, I make heavy use of Apple’s Screen Time APIs, such as ManagedSettings and FamilyControls. When an app is locked using a ShieldConfiguration, the user has to open my app in order to unlock it (e.g. enter a code). This is very cumbersome because no documented API exists to open the parent app (=my app) from the ShieldActionDelegate (also part of my app) when the user presses a button of the ShieldConfiguration. The ShieldActionDelegate callback just offers three options in its ShieldActionResponse: .none .defer .close .openParentApp is missing. We are working around this limitation by sending a local push notification that the user has to tap on. This has multiple drawbacks: It has to be ensured that notification permission has been granted. It has to be ensured that notifications can be delivered even while focus is enabled. Features such as Apple Intelligence notification summaries and notification prioritization can heavily delay delivering notifications and thus frustrate the user. Neither my users nor myself do understand why this is not possible in a smoother way, at least according to the documentation. There are 3rd party apps that have such functionality, they can directly open their own app from a button press in the Shield, see here: https://apps.apple.com/us/app/applocker-passcode-lock-apps/id1132845904 It would be great if Apple could level the playfield for all developers and document how this is achievable, because technically it clearly is. Thanks a lot and have a great day!

Screentime API new issues on iOS 17.4.1 and 17.5.1
Hi, I have a released screentime app ScreenZen. The last few days I've seen a disturbing spike in bug reports coming from people with 17.4.1 and 17.5.1 phones with no update to the app itself. People reported they saw the issue immediately after updating their iOS version. Unfortunately it is not replicable on all phones with those versions, so we haven't been able to replicate it on our test phones. It appears the issue is the ApplicationToken passed into ShieldActionExtension and ShieldConfigurationExtension does not match any of the ApplicationTokens that the user selected to block through FamilyControls. (The selected ApplicationTokens are being loaded through a group UserDefaults and they are indeed being loaded in the ShieldActionExtension in the bug reports).This is preventing the app from loading the correct settings and handling the blocking accordingly. I am trying to isolate this better with a new release with better logging, but would appreciate any help on this issue.

CallKit Call Directory database corruption (sqlite Code 11)
Hi everyone, I’ve filed a Feedback report (FB20986470) for a serious issue affecting the Call Directory database when add phone numbers for call blocking. When adding blocking numbers to a Call Directory extension, the system’s CallKit database (/private/var/mobile/Library/CallDirectory/CallDirectory.db) becomes corrupted. The reload call (reloadExtensionWithIdentifier) fails with error code 11 when the system tries to insert blocking entries, and the Console app on macOS shows the following errors: database corruption page 2265525 of /private/var/mobile/Library/CallDirectory/CallDirectory.db at line 81343 of [f0ca7bba1c] database corruption at line 79387 of [f0ca7bba1c] Error Domain=com.apple.callkit.database.sqlite Code=11 "sqlite3_step for query 'INSERT INTO PhoneNumberBlockingEntry (extension_id, phone_number_id) VALUES (?, (SELECT id FROM PhoneNumber WHERE (number = ?))), (?, (SELECT id FROM PhoneNumber WHERE (number = ?))),...)'" After this happens, CallKit becomes fully corrupted on the device and no further numbers can be added, even after: Disabling and re-enabling the extension Restarting the device (either force or soft restart) Reinstalling the app Waiting for a couple of minutes after this issue happens (that CallKit could possibly self-recovered) I also tested other call-blocking apps, and they all fail with the same error. The only thing that recovers the system is a full “Reset All Settings.” This issue has been reported by many users of my app, across multiple iOS versions and devices. Similar related issue reported by another developer: https://developer.apple.com/forums/thread/806129 Steps to Reproduce: Enable the Call Directory extension from a call-blocking app. Add and reload blocking numbers (a few thousand entries). Perform multiple reloads between additions. Check the Console, the corruption errors appear. From this point, all insert attempts fail system-wide. Expected Result: Entries should be inserted successfully, or the system should self-recover without persistent corruption. Actual Result: sqlite3_step fails with Code=11, and the Call Directory database remains corrupted until the user resets all settings. Additional Notes: All numbers are sorted and deduplicated before insertion. Happens intermittently after multiple reloads. The system log always shows internal database failure. Environment: Device: iPhone 16 Plus iOS 18.2 Beta (23C5027f) Xcode 16.1 (17B55) Attachments (included in Feedback FB20986470): sysdiagnose captured immediately after the failure (with Phone app General Profile) It seems like a system-level corruption affecting all Call Directory extensions once it occurs.

ShieldConfigurationExtension not working
I created a ShieldConfigurationExtension in Xcode 14.3 with File > New > Target > ShieldConfigurationExtension. This created the extension with all the necessary Info.plist values (correct NSExtensionPrincipalClass, etc.), with the extension included in embedded content in the host app target. No matter what I try, the extension is not getting invoked when I shield applications from my host app. The custom UI does not show as the shield, and looking at the debugger, an extension process is never invoked. I am shielding categories like this: let managedSettings = ManagedSettingsStore() ... managedSettings.shield.applicationCategories = .all() And my extension code overrides all the ShieldConfigurationDataSource functions. class ShieldConfigurationExtension: ShieldConfigurationDataSource { override func configuration(shielding application: Application) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding application: Application, in category: ActivityCategory) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding webDomain: WebDomain) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } override func configuration(shielding webDomain: WebDomain, in category: ActivityCategory) -> ShieldConfiguration { return ShieldConfiguration( backgroundBlurStyle: UIBlurEffect.Style.systemThickMaterial, backgroundColor: UIColor.white, icon: UIImage(systemName: "stopwatch"), title: ShieldConfiguration.Label(text: "You are in a Present Session", color: .yellow) ) } } What am I missing?

交易无法结束 (Transactions Unable to Finish)
有一个用户反馈7月8日充值了3笔后一直无法发起新的购买,总是提示已经购买。我们查了是之前的交易无法结束,我们使用StoreKit2,已经调用await transaction.finish()成功结束交易了,但是每次发起新支付时,Transaction.unfinished还会返回之前已完成的交易信息。 是设备或AppleID的问题么?用户尝试了重启设备、重新登录AppleID都没用。有什么办法解决呢? 用户无法结束的苹果交易id为:200002703899379、200002703900716、200002703902023。 A user reported that after making 3 purchases on July 8th, they have been unable to initiate new purchases, always receiving a prompt that the item has already been purchased. Upon investigation, we found that the previous transactions couldn't be finalized. We use StoreKit2 and have successfully called await transaction.finish() to end the transactions. However, every time a new payment is initiated, Transaction.unfinished still returns information about the previously completed transactions. Could this be an issue with the device or Apple ID? The user has tried restarting the device and re-logging into their Apple ID, but these attempts were unsuccessful. Is there any way to resolve this? The Apple transaction IDs that the user is unable to finalize are: 200002703899379, 200002703900716, 200002703902023.

Virtual Machine UDID Changes in macOS 15: Looking for Guidance on Development Workflow
Hello, We're developing endpoint security software using the Endpoint Security framework, and we've encountered challenges with the behavior change in macOS 15 regarding provisioning UDIDs in cloned VMs. The Change Prior to macOS 15, cloning a VM preserved its UDID (format: 0000FE00-9C4ED9F68BBDC72D). Starting with macOS 15, cloned VMs receive a new UDID generated from the host's Secure Enclave (format: b043d27202c7ac37ca3c6b82673302225485cae9), making each clone effectively a new device. Our Workflow We maintain a clean base VM image and clone it for each test run. We add the base VM's UDID to our provisioning profile once, then create clones which (previously) retained that same UDID, allowing us to start new testing cycles without re-registering devices. This is essential because our product involves low-level system integration through the Endpoint Security framework, and if something goes wrong during development, it has the potential to affect system stability. To prevent any cascading issues between test runs or different product versions, we need each test to start from a known clean state rather than reusing the same VM. The Challenge With each VM clone generating a new UDID, we're hitting Apple's device registration limits quickly. This particularly impacts: New team members who spin up VMs for the first time and can't run signed builds Our CI/CD pipeline where multiple test environments need provisioning profiles Developers testing different branches who need separate clean environments Current Workaround We've found that VMs created on macOS 14 and upgraded to macOS 15+ retain their original UDID format. However, we're concerned this workaround may stop working in future macOS versions, which would leave us without a viable path forward. If the workaround stops working, our fallback would be signing each CI build with a Developer ID signature to allow running on any device. However, we'd prefer to avoid this as it would significantly increase load on Apple's signing infrastructure for what are essentially internal test builds. We completely understand the security reasoning behind tying UDIDs to the host's Secure Enclave for Apple Account support. However, for development workflows that don't require Apple Account features in VMs but do require clean, isolated test environments, the previous behavior was quite valuable. Question Is there a recommended approach for teams in our situation? We're happy to explore alternative workflows if there's a pattern we're missing, or we'd be glad to provide more context if this is a use case Apple is considering for future updates. Thanks for any guidance you can provide! Feedback case: FB21389730

iOS Blocking Websocket Reconnection After Multiple VoIP Push Notifications
Hello, We have a Push-to-Talk (PTT) application that is already well established and widely used. Our app has the proper VoIP entitlement, which we are using to wake up the app and establish a WebSocket connection for real-time communication. We are also using CallKit as a supporting mechanism, but not as the primary interaction upon receiving the VoIP Push, since our use case differs from traditional full-duplex VoIP calls. While our implementation works correctly in many cases, we have noticed a consistent issue where, after multiple VoIP Push notifications, the system still delivers the push, but prevents the WebSocket from reconnecting. At this point, all connection attempts return errors such as: • "Software caused connection abort" This issue persists until the app is manually relaunched, after which the behavior resets and repeats. We are aware that VoIP Push was originally designed for full-duplex calls, but since Apple allows its use for other purposes through the entitlement, we would like to understand why this limitation is occurring and how to handle it properly. Questions: 1. Is iOS enforcing stricter background execution rules after multiple VoIP Push events within a short period? 2. Are there any recommended best practices to ensure reliable WebSocket reconnection in this scenario?

Is it possible to use the Matter.xcframework without using the MatterSupport extension for onboarding a device to our ecosystem?
Is it possible to use the Matter.xcframework without the MatterSupport extension for onboarding a Matter device to our own ecosystem(own OTBR and matter controller) for an official App Store release? Currently, we can achieve this in developer mode by adding the Bluetooth Central Matter Client Developer mode profile (as outlined here https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/darwin.md). For an official release, what entitlements or capabilities do we need to request approval from Apple to replace the Bluetooth Central Matter Client Developer mode profile? Thank you for your assistance.

How to optimize my app for for a carrier-provided satellite network?
Hello, I am working to integrate the new com.apple.developer.networking.carrier-constrained.app-optimized entitlement in my iOS 26 app so that my app can use a carrier-provided satellite network, and want to confirm my understanding of how to detect and optimize for satellite network conditions. (Ref: https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.networking.carrier-constrained.app-optimized ) My current approach: I plan to set the entitlement to true once my app is optimized for satellite networks. To detect if the device is connected to a satellite network, I intend to use the Network framework’s NWPath properties: isUltraConstrained — I understand this should be set to true when the device is connected to a satellite network. (Ref: https://developer.apple.com/documentation/network/nwpath/isultraconstrained ) linkQuality == .minimal — I believe this will also be set in satellite scenarios, though it may not be exclusive to satellite connections. (Ref: https://developer.apple.com/documentation/network/nwpath/linkquality-swift.enum/minimal ) Questions: Is it correct that isUltraConstrained will reliably indicate a satellite connection? Should I also check for linkQuality == .minimal, or is isUltraConstrained sufficient? Are there any additional APIs or best practices for detecting and optimizing for satellite connectivity that I should be aware of? Thank you for confirming whether my understanding and approach are correct, and for any additional guidance.

PKPassLibrary.requestAutomaticPassPresentationSuppression Behavior
We are implementing a feature that uses PKPassLibrary.requestAutomaticPassPresentationSuppression to prevent the Wallet from appearing when unlocking a lock. We have already completed the approval process for the entitlement to enable Pass Presentation Suppression. In most cases, our code snippet works as expected, and the result is .success. However, we are also encountering other results, such as .denied, .alreadyPresenting, and .cancelled or .notSupported, which cause the Wallet to appear for users. Here's the code snippet we're using: PKPassLibrary.requestAutomaticPassPresentationSuppression { result in logger.log( .info, "PKPassLibrary suppression result: \(result.description)", LogContext.homeFeature ) } I would appreciate clarification on the following points: What's the meaning of each result type (.denied, .alreadyPresenting, .cancelled, .notSupported) beyond what is mentioned in the documentation? The documentation here does not provide additional details. What is the recommended handling for these specific result states? Should we be taking different actions or retries based on each case? Thank you very much for your help. Best, Ramiro.

SwiftData and CloudKit
Recently I've been working on a demo project called iLibrary. The main goal was to learn more about CloudKit and SwiftData. After a while I noticed that there were some hangs/freezes when running the app in debug mode. I first tried this with Xcode 15.4 and iOS 17.5. Here the hang only appears at the beginning, but only for a few seconds. But when I exit debug mode, there are no more hangs. With Xcode 16 beta 4 and iOS 18 it looks completely different. In this case, the hangs and freezes are always present, whether in debug mode or not. And it's not just at the beginning, it's throughout the app. I'm aware that this is still a beta, but I still find this weird. And when I profile this I see that the main thread gets quite overloaded. Interestingly, my app doesn't have that many operations going on. So I guess something with the sync of SwiftData or my CloudKitManger where I fetch some records from the public database is not running fine. Lastly, I wanted to delete the iCloud app data. So I went to Settings and tried to delete it, but it didn't work. Is this normal? Does anyone have any idea what this could be? Or has anyone encountered this problem as well? I'd appreciate any support. My project: https://github.com/romanindermuehle/iLibrary
