Allowing workaround for FamilyActivityPicker crash
As discussed and acknowledged here, there is a known bug with the FamilyActivityPicker. When a user expands a category that contains enough tokens to exceed the 50mb memory limit, the FamilyActivityPicker crashes. This happens quite frequently for heavy Safari users. An apple engineer mentioned on this thread that WebDomains shown in the picker are present based on the last 30 days of usage data as surfaced by WebKit. Is there any way a user can clear these WebDomains? Either programatically through our app or any other process we can guide them to as a workaround while this issue is getting fixed?

iOS 26 beta 8 – AlarmKit – Custom sounds in Library/Sounds do not play
I put a test.mp3 (30 sec) file into the App Bundle. I scheduled an AlarmKit alarm with the file name test.mp3. The custom sound plays ✅ I copied the file from the App Bundle to Library/Sounds/test2.mp3. I scheduled an AlarmKit alarm with the file name test2.mp3. Instead of playing the custom sound, it falls back to the default sound ❌ According to the documentation, sounds placed in Library/Sounds should be playable: I filed report FB19779004 on August 20, but haven’t received any response yet. This functionality is critical for our use case, so could you please let me know whether this is expected to be fixed soon, or if I’m misunderstanding the intended behavior?

Donating the shortcut once a user taps a button. The shortcut is not appearing on the lock screen. Everything else is working as expected. The Shortcut is appearing in the Shortcuts App and is working via Siri. In developer settings I have Display Recent Shortcuts -> On Display Donations on Lock Screen -> On Allow Any domain -> On Allow Unverified sources -> On Running iOS 16.2, iPhone 11.

FamilyActivityPicker Crashing / Freezing
Our users report frequent crashes with the FamilyActivityPicker. Since this is a screen controlled by Apple, I'm assuming that there's nothing I can do to prevent these crashes. I'm wondering, though, if there's any way to gracefully handle these crashes? When this happens, the following is printed to the console: [com.apple.FamilyControls.ActivityPickerExtension(1121)] Connection to plugin invalidated while in use. Does anyone know how to handle/catch this error?

Non-removable system extensions from UI attribute from MDM is not getting applied to the extension under Apps tab in new Mac OS 26 (Tahoe)
We have an application which is written in Swift, which activates Transparent Proxy network extension. We are using Jamf MDM profile for deployment. To avoid the user deleting / disabling the extension from General -> LogIn Items & Extension -> Network Extensions screen, we are using "Non-removable system extensions from UI" attribute under Allowed System Extensions and Teams IDs section. In new Mac OS 26 (Tahoe), user can also enable/disable the extension from General -> LogIn Items & Extension -> Apps tab. The "Non-removable system extensions from UI" attribute set in Jamf MDM profile does not apply to this tab. Same attribute is working for General -> LogIn Items & Extension -> Extensions tab and there the slider is greyed out and Remove option is not available under more menu. Is there any new key/configuration defined to disable the slider from General -> LogIn Items & Extension -> Apps tab? Created https://feedbackassistant.apple.com/feedback/18198031 - FB18198031 feedback assistant ticket as well.

FamilyActivityPicker Crash on selecting some items
Both view and modifier versions of the FamilyActivityPicker crash randomly when selecting some items (usually the other option) throwing these in the console: [com.apple.FamilyControls.ActivityPickerExtension(1150.1)] Connection to plugin invalidated while in use AX Lookup problem - errorCode:1100 error:Permission denied portName:'com.apple.iphone.axserver' PID:22091 ( 0 AXRuntime 0x00000001c603b0fc _AXGetPortFromCache + 800 1 AXRuntime 0x00000001c603cce0 AXUIElementPerformFencedActionWithValue + 700 2 UIKit 0x0000000230de3ec8 DDE6E0C5-2AC3-3C73-8CFE-BC88DE35BB5F + 1453768 3 libdispatch.dylib 0x0000000103ef0b98 _dispatch_call_block_and_release + 32 4 libdispatch.dylib 0x0000000103ef27bc _dispatch_client_callout + 20 5 libdispatch.dylib 0x0000000103efa66c _dispatch_lane_serial_drain + 832 6 libdispatch.dylib 0x0000000103efb408 _dispatch_lane_invoke + 408 7 libdispatch.dylib 0x0000000103f08404 _dispatch_root_queue_drain_deferred_wlh + 328 8 libdispatch.dylib 0x0000000103f07a38 _dispatch_workloop_worker_thread + 444 9 libsystem_pthread.dylib 0x00000001f0824f20 _pthread_wqthread + 288 10 libsystem_pthread.dylib 0x00000001f0824fc0 start_wqthread + 8 ) This also happens in production apps like the Opal. The questions are: At least how to detect it to be able to manually reload the sheet (like what Opal does and shows an alert when this happens) How to prevent it in the first place? I really appreciate any help you can provide.

iOS 18 breaks IMAP Mail retrieval for some users
Posting here for wider visibility... All over the internet, apple discussions, etc. Seems that this is affecting thousands of people but apparently not millions...othewise we'd have a fix by now. This started showing up in iOS 18 beta and then continued into 18.0, 18.1, and now 18.2 Symptoms are unable to retrieve emails from IMAP mail server. Some have mentioned Dovecot IMAP server. This author happens to have Dovecot IMAP and yes, once iOS 18.0, 18.x was installed, email sync no longer works.

Device Activity Reports are returning a blank screen in release mode
There is an inconsistent issue when views are rendered from the Device Activity Report Extension. This issue is noticeable only on release versions and it works fine in debug mode. Around 80% of the times, the Report Views return blank screen and this is only the case when a weekly/monthly filter is used. Although, it works as expected for daily report views. My questions are: How are all the Report Activity Views working fine in debug mode but not in release mode? How the daily activity filter works fine in the release mode but the weekly/monthly filters don't work? Is this because of a memory limit issue in the extension? As of now, I have the family-controls(distribution) entitlement only for the app and for the extensions I only have family-controls(development) entitlement. Do I need to request for family-controls(Distribution) entitlement even for the extensions? I have seen threads on the forum mentioning the blank screen issue associated with the DeviceActivityReport but haven't found a solution to it. Any suggestions/feedback would be of great help, thanks.

Identifying Essential Apple Bundle ID for Apple Watch-iPhone Connectivity in MDM Environment
I am experiencing difficulties in fully integrating my Apple Watch with a supervised iPhone under MDM control. While I have successfully paired the watch with the iPhone, I am facing issues with some apps not syncing or appearing on the Apple Watch. This issue persists despite having allowed their bundle IDs in the MDM’s whitelist. Could anyone provide guidance on which specific Apple bundle ID is crucial for maintaining the connectivity and functionality between the iPhone and the Apple Watch? Understanding this would help in ensuring that the necessary bundle ID is whitelisted in the MDM settings, thus resolving the app visibility and functionality issues on the Apple Watch.

UserDefaults.didChangeNotification not firing
Hi, I'm currently working on an app made originally for iOS 15. On it, I add an observer on viewDidLoad function of my ViewController to listen for changes on the UserDefault values for connection settings. NotificationCenter.default.addObserver(self, selector: #selector(settingsChanged), name: UserDefaults.didChangeNotification, object: nil) Said values can only be modified on the app's section from System Settings. Thing is, up to iOS 17, the notification fired as expected, but starting from iOS 18, the notification doesn't seem to be sent by the OS. Is there anything I should change in my observer, or any other technique to listen for the describe event? Thanks in advance.

Crash (KERN_INVALID_ADDRESS) on IOS 26.2 GM when calling isEligibleForAgeFeatures
We recently released an update to our app to prepare for TX SB2420. Almost immediately on release, we started getting crash reports of crashes when calling isEligibleForAgeFeatures. Crashed: com.apple.root.user-initiated-qos.cooperative EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000004 Is it possible that these are beta users that have IOS 26.2 RC or is there a bug in the release version of IOS 26.2? Note: The crash reports are coming from Crashlytics so we are not getting OS build identifiers other than version "26.2"

How to debug Quick Look Preview Extension
When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window: Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex (where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error Can't get generator at QuickLookPreviewExtension.appex How can I debug a Quick Look Preview Extension?

Refresh Widget doesn't work from background push notification.
As stated in other posts like: https://developer.apple.com/forums/thread/734488 https://developer.apple.com/forums/thread/652946?answerId=823555022#823555022 Even though the recommended way from Apple documentation is to use push notifications to reload widgets timelines calling WidgetCenter.shared.reloadAllTimelines(), it is unreliable and I couldn't find a pattern of why it works 10% of times and not the other 90%. While the debugger is connected to the App it always works though. My widget needs to reflect updated information otherwise it becomes useless since it display smart home devices states such as the Apple Home widget does as well.

Permission error occurs when I use setDefaultApplication(at:toOpen:completion:)
I'd like to set my macOS app written in Swift as default app when opening .mp4 file. I think I can do it with setDefaultApplication(at:toOpen:completion:). https://developer.apple.com/documentation/appkit/nsworkspace/3753002-setdefaultapplication However, permission error occurs when I use it. The error is: Error Domain=NSCocoaErrorDomain Code=256 "The file couldn’t be opened." UserInfo={NSUnderlyingError=0x6000031d0150 {Error Domain=NSOSStatusErrorDomain Code=-54 "permErr: permissions error (on file open)"}} I tried to give my app full-disk access, but it didn't work. I also tried to use setDefaultApplication(at:toOpenFileAt:completion:), then it works with no error, but it effects on only one file. What I want to do is to set my app as default app of all .mp4 files. How do I achieve this? My code is like below: let bundleUrl = Bundle.main.bundleURL NSWorkspace.shared.setDefaultApplication(at: bundleUrl, toOpen: .mpeg4Movie) { error in print(error) } Thank you.

Is testing of Age Range API available in xcode simulator?
From https://developer.apple.com/forums/thread/803945?answerId=862153022#862153022, the testing of Age Range API was not available through xcode simulator back in Oct 2025. Is this available now? In particular: Is requestAgeRange testing available through simulator? Is requestAgeRange testing with sandbox account available through simulator? Is isEligibleForAgeFeatures available through simulator? Is isEligibleForAgeFeatures testing with sandbox account available through simulator? If the answer is "yes" to any of the above, which version of the xcode and ios version should I use? So far I didn't get any of the above working on the simulator, and I can't find any documentation on the answers above. Thank you!

WeatherKit API inaccessible for some users
Hi All, I’m puzzled by this issue: my app uses WeatherKit to fetch hourly UV-index and temperature forecasts. The same build, running on the latest iOS, succeeds on most devices but consistently fails on a few. Strangely, the paired Apple Watch version retrieves the data without problems. Could WeatherKit be applying per-user throttling? Any insight would be greatly appreciated.

Can FamilyControls ApplicationToken or CategoryToken expire? If yes, how to detect and handle it?
How to programmatically check if ApplicationToken or ActivityCategoryToken is expired in FamilyActivityPicker? I'm building a Screen Time-based parental control app using FamilyControls and ManagedSettings. We use FamilyActivityPicker to allow the user to select apps and categories to restrict, and we apply the shield using: store.shield.applications = .specific(selection.applicationTokens) store.shield.applicationCategories = .specific(selection.categoryTokens) Sometimes, we observe that the shield silently fails to apply — no error is thrown, but the restrictions aren't enforced. I suspect this may be due to expired or invalid tokens, possibly if the app was removed or the selection became stale. My Questions: Can ApplicationToken or ActivityCategoryToken expire or become invalid over time? If yes, is there a supported or recommended way to detect whether a token is still valid before applying it to the shield? Is comparing the current shield values (store.shield.applications and store.shield.applicationCategories) after applying them a reliable validation method? What's the best practice to handle expired tokens (e.g. re-prompt the FamilyActivityPicker, or show a fallback)? What Is the Expiration Duration of Tokens from FamilyActivityPicker? Any guidance or insight from the Screen Time/FamilyControls team would be greatly appreciated! Thank you!

AlarmKit Not Playing Custom Sound or Named System Sounds - iOS 26 beta 4 (23A5297i)
I'm using the new AlarmKit framework to schedule and trigger alarms in my Swift app in iOS 26 beta 4 (23A5297i). I'm trying to customize the alarm sound using a sound file embedded in the app bundle or by referencing known system tones. Problem: No matter what I pass to .named("sound-2"), whether a file bundle url, .named("sound-2.caf"), tried .mp3, .caf & .aiff, or a known iOS system sound like .named("Radar") ("Chimes", etc.), the alarm always plays the default system alert tone. There's no error or warning, but the custom or specified sound is silently ignored. sound: .named("sound-2") Question: What is the correct method or approach to play custom sound / music when Alarm Triggers? What .named("...") expects file name, file Path URL or System sound name? Is there any specific audio file length accepted or specific format? Challenge: The alarm functionality feels incomplete without support for custom sounds. A single default alert tone is often not sufficient to wake up users effectively. Hope it will be fixed in the next iOS updates.
