New features for APNs token authentication now available
Team-scoped keys introduce the ability to restrict your token authentication keys to either development or production environments. Topic-specific keys in addition to environment isolation allow you to associate each key with a specific Bundle ID streamlining key management. For detailed instructions on accessing these features, read our updated documentation on establishing a token-based connection to APNs.

App Crash in GameController when accessing GCKeyboard.coalesced on iPad
We are developing a hybrid iOS app where Angular content is rendered inside a WKWebView, hosted by a native Swift application. We use the GameController framework to detect whether an external Bluetooth keyboard is connected to an iPad. The following code is executed when the app enters the foreground and also when requested by the web layer: func keyboardStatusHandler(){ let isKeyboardConnected = GCKeyboard.coalesced != nil if(!isKeyboardConnected){ //sent status to Angular } else { //sent status to Angular } } Crash details We are seeing intermittent crashes on iPad with the following stack trace: Crashed: GCDeviceSession.HID 0 libobjc.A.dylib 0x7db8 objc_retain_x8 + 16 1 libsystem_blocks.dylib 0xfb8 void HelperBase<ExtendedInline>::copyCapture<(HelperBase<ExtendedInline>::BlockCaptureKind)3>(unsigned int) + 48 2 libsystem_blocks.dylib 0xbc4 HelperBase<GenericInline>::copyBlock(Block_layout*, Block_layout*) + 108 3 libsystem_blocks.dylib 0xc94 _call_copy_helpers_excp + 60 4 libsystem_blocks.dylib 0xef8 _Block_copy + 412 5 libdispatch.dylib 0x1a70 _dispatch_Block_copy + 32 6 libdispatch.dylib 0x792c dispatch_async + 56 7 libdispatch.dylib 0x792c dispatch_channel_async + 56 8 GameController 0xea6dc -[GCKeyboardInput _handleKeyboardEvent:] + 324 9 GameController 0x22508 __53-[_GCKeyboardEventHIDAdapter initWithSource:service:]_block_invoke + 376 10 GameController 0x11d30 -[_GCHIDEventSubject publishHIDEvent:] + 268 11 GameController 0xb79cc __40-[_GCHIDEventUIKitClient initWithQueue:]_block_invoke_3 + 44 12 libdispatch.dylib 0x1b584 _dispatch_client_callout + 16 13 libdispatch.dylib 0x12088 _dispatch_async_and_wait_invoke_and_complete_recurse + 272 14 libdispatch.dylib 0x8448 _dispatch_async_and_wait_f + 108 15 GameController 0xb7984 __40-[_GCHIDEventUIKitClient initWithQueue:]_block_invoke_2 + 132 16 GameController 0xb746c __48-[__GCHIDEventUIKitClient _initWithApplication:]_block_invoke + 256 17 UIKitCore 0x11fd394 __61-[UIEventFetcher _setHIDGameControllerEventObserver:onQueue:]_block_invoke_3 + 40 18 libdispatch.dylib 0x1aac _dispatch_call_block_and_release + 32 19 libdispatch.dylib 0x1b584 _dispatch_client_callout + 16 20 libdispatch.dylib 0xa2d0 _dispatch_lane_serial_drain + 740 21 libdispatch.dylib 0xadac _dispatch_lane_invoke + 388 22 libdispatch.dylib 0x151dc _dispatch_root_queue_drain_deferred_wlh + 292 23 libdispatch.dylib 0x14a60 _dispatch_workloop_worker_thread + 540 24 libsystem_pthread.dylib 0xa0c _pthread_wqthread + 292 25 libsystem_pthread.dylib 0xaac start_wqthread + 8 Observed scenarios Crash occurs when the app transitions from background to foreground Crash also occurs when the Angular layer requests keyboard status, triggering the same code path Questions Has anyone encountered crashes related to GCKeyboard.coalesced or GCKeyboardInput like this? Are there known issues with the GameController framework when querying keyboard state during app lifecycle transitions? Is there a recommended or safer way to detect external keyboard connection status on iPad (especially when using WKWebView)? Any insights, known platform issues, or suggested workarounds would be greatly appreciated. Thanks!

SwiftData .autosaveEnabled / rollback() trouble
Hello, In my iOS/SwiftUI/SwiftData app, I want the user to be able to hit [Cancel] from editing in a detail screen and return to the previous screen without changes being saved. I believed that setting autosaveEnabled to false and/or calling .rollback would prevent changes from being saved, unless/until I call .save() when the user clicks [Save], but this does not seem to be correct. I set modelContext.autosaveEnabled = false and I call modelContext.rollback() when the user hits [Cancel], but any changes they made are not rolled back, but saved even if I don’t call save(). I have tried setting autosaveEnabled to false when I create the ModelContainer on a @MainActor function when the App starts, and in the detail/edit screen’s .onAppear(). I can see that .rollback is being called when the [Cancel] button is tapped. In all cases, any changes the user made before hitting [Cancel] are saved. The Developer Documentation on autosaveEnabled includes this: “The default value is false. SwiftData automatically sets this property to true for the model container’s mainContext." I am working on the mainContext, but it appears that setting autosaveEnabled to false has no effect no matter where in the code I set it. If someone sees what I am doing wrong, I’d sure appreciate the input. If this description doesn’t explain the problem well enough, I’ll develop a minimal focused example.

Now Playing / Recently Played API
We are using the MPNowPlayingInfoCenter API to provide information to the “Now Playing” system UI. This works as expected, except that when the app is manually terminated, the information is removed from the UI. Our question is: Some apps (for example, Audible) are able to appear in the “Recently Played” section of the UI. This section seems to show a history of apps that previously provided “Now Playing” information but are not currently playing anything. We would like to know which API is used to achieve this behavior.

MusicKit JS user token returns 403 immediately after password change
Has anyone seen this issue? We have a user who changed their Apple ID password about 5 days ago. Now when they authenticate via MusicKit JS: authorize() succeeds and returns a user token Immediately calling any /me/ endpoint returns 403 "Invalid authentication" (code 40300) Developer token works fine on catalog endpoints User has active Apple Music subscription Other users work fine through the same flow App doesn't appear in user's "Apps Using Your Apple ID" We've tried: Calling unauthorize() before authorize() Clearing localStorage/sessionStorage/cookies Multiple re-auth attempts over several days The token is freshly issued but Apple's API immediately rejects it. Anyone encountered this after a password change? Any workarounds?

Speed AppleTV > Distorted HomePod Audio
Hey everyone. Ever since installed OS26 (and 26.1 now) - whenever I fast play any video on 1.25x, 1.5x, 2x on the AppleTV - the audio gets massively distorted on HomePods. Be it on YouTube, Difuse, or any supporting app. I even tried mirroring from iPhone -same issue. Anyone else experiencing the same? I noticed no posts about troubleshooting.

Questions about DeclaredAgeRange's isEligibleForAgeFeatures instance variable
Our team is in the process of updating our apps to comply with Texas's new state law. In order to minimize user confusion and provide the most ideal flow to access the app as possible, we have a few questions we would like answered. Summary of questions: Is isEligibleForAgeFeatures intended to be accurate and accessible before the user has accepted the Age Range permissions prompt? As other US states and/or other countries adopt a similar law going forward, will this instance variable cover those locations? Will the runtime crashes on isEligibleForAgeFeatures and other symbols in the DeclaredAgeRange framework be addressed in a future RC or in the official release? Details and Investigations: With regards to isEligibleForAgeFeatures, our team has noticed that this value is always false before the age range prompt has been accepted. This has been tested on the XCode RC 26.2 (17C48). Assuming the request needs to be accepted first, isEligibleForAgeFeatures does not get updated immediately when the user chooses to share their age range (updated to true, when our sandbox test account is a Texas resident). Only upon subsequent relaunches of the app does this return a value that reflects the sandbox user's location. Is isEligibleForAgeFeatures intended to be accurate and accessible before the user has accepted the Age Range permissions prompt? This leads to our follow-up question to clarify whether isEligibleForAgeFeatures explicitly correlates to a user in an affected legal jurisdiction–if future US states and/or other countries adopt a similar law going forward, will this instance variable cover those locations? Can we also get confirmation about whether the runtime crash on isEligibleForAgeFeatures and other symbols in the DeclaredAgeRange framework will be addressed in a future RC or in the official release? Thank you.

BGContinuedProcessingTask register block not called, submit does not throw an error
I implemented BGContinuedProcessingTask in my app and it seems to be working well for everyone except one user (so far) who has reached out to report nothing happens when they tap the Start Processing button. They have an iPhone 12 Pro Max running iOS 26.1. Restarting iPhone does not fix it. When they turn off the background processing feature in the app, it works. In that case my code directly calls the function to start processing instead of waiting for it to be invoked in the register block (or submit catch block). Is this a bug that's possible to occur, maybe device specific? Or have I done something wrong in the implementation? func startProcessingTapped(_ sender: UIButton) { if isBackgroundProcessingEnabled { startBackgroundContinuedProcessing() } else { startProcessing(backgroundTask: nil) } } func startBackgroundContinuedProcessing() { BGTaskScheduler.shared.register(forTaskWithIdentifier: taskIdentifier, using: .main) { @Sendable [weak self] task in guard self != nil else { return } startProcessing(backgroundTask: task as? BGContinuedProcessingTask) } let request = BGContinuedProcessingTaskRequest(identifier: taskIdentifier, title: title, subtitle: subtitle) request.strategy = .fail if BGTaskScheduler.supportedResources.contains(.gpu) { request.requiredResources = .gpu } do { try BGTaskScheduler.shared.submit(request) } catch { startProcessing(backgroundTask: nil) } } func startProcessing(backgroundTask: BGContinuedProcessingTask?) { // FIXME: Never called for this user when isBackgroundProcessingEnabled is true }

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Zsh kills Python process with plenty of available VM
On a MacBook Pro, 16GB of RAM, 500 GB SSD, OS Sequoia 15.7.1, M3 chip, I am running some python3 code in a conda environment that requires lots of RAM and sure enough, once physical memory is almost exhausted, swapfiles of about 1GB each start being created, which I can see in /System/Volumes/VM. This folder has about 470 GB of available space at the start of the process (I can see this through get info) however, once about 40 or so swapfiles are created, for a total of about 40GB of virtual memory occupied (and thus still plenty of available space in VM), zsh kills the python process responsible for the RAM usage (notably, it does not kill another python process using only about 100 MB of RAM). The message received is "zsh: killed" in the tmux pane where the logging of the process is printed. All the documentation I was able to consult says that macOS is designed to use up to all available storage on the startup disk (which is the one I am using since I have only one disk and the available space aforementioned reflects this) for swapping, when physical RAM is not enough. Then why is the process killed long before the swapping area is exhausted? In contrast, the same process on a Linux machine (basic python venv here) just keeps swapping, and never gets killed until swap area is exhausted. One last note, I do not have administrator rights on this device, so I could not run dmesg to retrieve more precise information, I can only check with df -h how the swap area increases little by little. My employer's IT team confirmed that they do not mess with memory usage on managed profiles, so macOS is just doing its thing. Thanks for any insight you can share on this issue, is it a known bug (perhaps with conda/python environments) or is it expected behaviour? Is there a way to keep the process from being killed?

Declared Age Range API: iOS/macOS support
While preparing my app for Declared Age Range capability usage, I've noticed a weird behaviour: the same code works for iOS, but not for macOS. My project uses same target for both platforms, so the capability is enabled for both platforms. The business logic layer is also shared across between platforms. Both UI layers are writter in SwiftUI. The iCloud account used for testing on iOS and macOS devices is the same, so even the consent is shared across both devices. While requestAgeRange(ageGates:) seems to work just fine for iOS app, for macOS app it always throws Not available error (DeclaredAgeRange.AgeRangeService.Error.notAvailable) Am I missing something? Could the API be somehow unavailable for macOS? Should I use AgeRangeService.shared.requestAgeRange(ageGates:in:) for macOS instead of SwiftUI's @Environment-based approach? Also, after giving permission, is there a way to actually revoke it? In Age Range for Apps menu I can only view the list of apps that have my consent to share my age range, but not the ability to revoke it.

BGTaskScheduler Terminated due to memory issue
Hello everybody! I'm currently working on a Bluetooth Low Energy Sync that is using BGTaskScheduler & successfully running periodically in the Background on iOS 26. I did watch this years WWDC Session 227 (Finish tasks in the background) & follow the recommendations as suggested. Currently, the App is only using 37 Mb (iPhone 12 mini) & no Location or other services are running in Background. However, when opening Safari & scrolling through some webpages, the App is killed because of "Terminated due to memory issue". I profiled the App & followed advice when it comes to reducing the memory footprint of the App. Are there any additional steps I can take to prevent the App being killed? Are there any recommendations for periodically scheduled Tasks when it comes to the Interval? Do more frequent Tasks (30min compared to one or two hours) have any impact? I tried many different schedules but none seem to make a difference. From my observation, the App is first suspended & eventually killed because of the Memory Pressure. Any hints, suggestions or recommendations are highly appreciated! Thanks a lot for the support!

Thread Network API not working

application(_:didFinishLaunchingWithOptions:) not called on MDM iPads after overnight idle — app resumes without cold start
We are seeing a strange lifecycle issue on multiple MDM-managed iPads where application(_:didFinishLaunchingWithOptions:) is not called after the device is idle overnight. Even if we terminate the app manually via the app switcher, the next morning the system does not perform a cold launch. Instead, the app resumes directly in: applicationDidBecomeActive(_:) This causes all initialization logic that depends on didFinishLaunching to be completely skipped. This behavior is consistent across four different supervised MDM devices. Environment Devices: iPads enrolled in MDM (supervised) iOS version: 18.3 Xcode: 16.4 macOS: Sequoia 15.7.2 App type: Standard UIKit iOS app App: Salux Audiometer (App Store app) Expected Behavior If the app was terminated manually using the app switcher, the next launch should: Start a new process Trigger application(_:didFinishLaunchingWithOptions:) Follow the normal cold-start lifecycle Actual Behavior After leaving the iPad idle overnight (8–12 hours): The next launch skips didFinishLaunching The app resumes directly in applicationDidBecomeActive No new process is started App behaves as if it had been suspended, even though it was manually terminated Logs (Relevant Extracts) Day 1 — Normal cold launch [12:06:44.152 PM] PROCESS_STARTED [12:06:44.214 PM] DID_FINISH_LAUNCHING_START launchOptions=[] [12:06:44.448 PM] DID_FINISH_LAUNCHING_END We then used the app and terminated it via app switcher. Day 2 — Unexpected resume without cold start [12:57:49.328 PM] APP_DID_BECOME_ACTIVE No PROCESS_STARTED No didFinishLaunching No cold-start logs This means the OS resumed the app from a previous state that should not exist. Reproducible Steps Use an MDM-enrolled iPad. Launch the app normally. Terminate it manually via the multitasking app switcher. Leave the device idle overnight (8–12 hours). Launch the app the next morning. Observe that: didFinishLaunching does not fire applicationDidBecomeActive fires directly Questions for Apple Engineers / Community Is this expected behavior on MDM-supervised devices in iOS 18? Are there any known OS-level changes where terminated apps may be revived from disk/memory? Could MDM restrictions or background restoration policies override app termination? How can we ensure that our app always performs a clean initialization when launched after a long idle period? Additional Information We have full logs from four separate MDM iPads showing identical behavior. Happy to share a minimal reproducible sample if required.

[Texas SB 2420] How to Retrieve Parental Consent Status
After reading the news below, we are currently working on updating our app in preparation for the enforcement of Texas SB 2420. https://developer.apple.com/news/?id=2ezb6jhj Based on the information in the announcement, we understand that parents will be able to revoke their consent for apps. However, we are unsure how an app is supposed to obtain or verify the parent’s consent status in the first place. We reviewed the Declared Age Range API and PermissionKit’s Significant Change API, but could not find any functionality related to this. If anyone with expertise on this topic has insight, we would greatly appreciate your guidance. Thank you in advance.

Age range permission prompt text configurability
For other permission prompts in the iOS ecosystem, we have the option to configure the text shown in the prompt via keys in the Info.plist. This does not appear to be the case with regards to the age range permission prompt. The text of the prompt implies the app includes a differentiated experience for child or teen content and that confirming age unlocks more features (making it seem optional for using the app). Is there a plan for app developers to be able to update that permission prompt similarly to how we can configure others? If so, is there any timeline we can expect that on?

AgeRangeService system prompt does not allow displaying upper age threshold (e.g. 18+)
We are using AgeRangeService.requestAgeRange(ageGates:in:) with an age gate of 18 to verify adult users. The system prompt always displays the lower-bound wording (“17 or Younger”), even when the app’s requirement is to verify users who are 18 or older. We understand the UI is system-controlled; however, this wording causes confusion for users, QA, and product teams, as it appears to indicate a child-only flow even when requesting adult verification. Based on the demonstration video, it appears that they have another more coherent message. In Apple's example, it is different, and it is correct that we need to specify 18 years or older in the implementation. A little more context might be helpful, but we are creating a kind of wrapper with React Native that receives that value as a parameter, which is 18.

CloudKit CKRecordZone Deletion Issue
CloudKit CKRecordZone Deletion Issue Problem: CloudKit record zones deleted via CKDatabase.modifyRecordZones(deleting:) or CKModifyRecordZonesOperation are successfully removed but then reappear. I suspect they are automatically reinstated by CloudKit sync, despite successful deletion confirmation. Environment: SwiftData with CloudKit integration Custom CloudKit zones created for legacy zone-based sharing Observed Behavior: Create custom zone (e.g., "TestZone1") via CKDatabase.modifyRecordZones(saving:) Copy records to zone for sharing purposes Delete zone using any CloudKit deletion API - returns success, no errors Immediate verification: Zone is gone from database.allRecordZones() After SwiftData/CloudKit sync or app restart: Zone reappears Reproduction: Tested with three different deletion methods - all exhibit same behaviour: modifyRecordZones(deleting:) async API CKModifyRecordZonesOperation (fire-and-forget) CKModifyRecordZonesOperation with result callbacks Zone deletion succeeds, change tokens (used to track updates to shared records) cleaned up But zones are restored presumably by CloudKit background sync Expected: Deleted zones should remain deleted Actual: Zones are reinstated, creating orphaned zones
