I have a stand-alone watchOS app that starts a WKExtendedRuntimeSession and a 1-second repeating timer when a button is pressed. No CPU-intensive stuff happens during this extended (background) time. On watchOS 9, this worked perfectly until I stopped it again (or after the hour I get out of a Mindfulness Session Type has passed, and the extended runtime session expires). The screen could go dark, and the timer would keep running. On watchOS 10, I get about 50 seconds when the screen goes dark, and then the timer just stops. No delegate methods are called (i.e. no "extendedRuntimeSession...willExpire()" or "...didInvalidateWith()" is called), though. Also, the scenePhase does not change at this point, it remains at inactive. The execution just stops. When I tap the watch to turn the screen back on, the timer resumes as if nothing happened. Does anybody know what's going on here? Has something changed in WKExtendedRuntimeSessions in watchOS 10, or is it a bug? I tried removing the timer and changing it to a recursive DispatchAsync.main.asyncAfter block, but it yielded the same result.

FeedbackID: FB13636921 I'm using /usr/sbin/screencapture -v -x -C -k -R 0,0,500,500 /path/to/a/movfile/in/a/folder/in/my/apps/sandbox/Group/Container in my app to allow users to capture screenshots and recordings. Screenshots keep working fine on macOS Sonoma 14.4b23E5196e, but video recordings no longer work. I'm guessing the following log output has something to do with it: default 15:01:53.151819+0100 screencapture sampleBuffer: start recording time: 3123.604833 target: 3123.474266, overshot: 0.130568 error 15:01:53.185179+0100 screencapture <private>:246:<private> Not writable url (null).!folderIsWritable == true error 15:01:53.185236+0100 screencapture <private>:50:<private> We could not create a byte stream! error 15:01:53.185252+0100 screencapture <private>:87:<private> NULL byte stream. error 15:01:53.185298+0100 screencapture <private>:3479:<private> ### Err -45, error 15:01:53.185312+0100 screencapture <private>:3814:<private> ### Err -45, error 15:01:53.185334+0100 screencapture <<<< AVCaptureMovieFileOutput >>>> Fig assert: "status == 0 " at (AVCaptureMovieFileOutput.m:2522) - CMIOFileWritingControlTokenStartWriting (err=-45) error 15:01:53.185374+0100 screencapture <private>:1885:<private> ### Err -67452, error 15:01:53.185388+0100 screencapture <private>:303:<private> FigMovieFormatFileWriter::PostProcessMovie: WriteMovie() errored!!! -67452 error 15:01:53.185476+0100 screencapture <private>:4687:<private> consolidate movie fragments err : -17913 default 15:01:53.185610+0100 screencapture <<<< AVError >>>> AVLocalizedErrorWithUnderlyingOSStatus: Returning error (AVFoundationErrorDomain / -11800) status (-45) default 15:01:53.186201+0100 screencapture didFinishRecording: No trim finish. duration: 0.000000s size: 0, error: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={AVErrorRecordingSuccessfullyFinishedKey=false, NSLocalizedDescription=The operation could not be completed, NSLocalizedFailureReason=An unknown error occurred (-45), NSURL=file:///Users/eternalstorms/Library/Group%20Containers/group.com.apple.screencapture/ScreenRecordings/3ED15EE7-A814-47A7-A398-29D5A6AD03C1.mov, NSUnderlyingError=0x6000031d80c0 {Error Domain=NSOSStatusErrorDomain Code=-45 "fLckdErr: file is locked"}} error 15:01:53.186290+0100 screencapture recording failed.

Hello, I'm preparing my app Tameno for iOS 18, adding a couple of Control Center widgets. One of them allows users to select their favorite interval. But in the context of my app, only seconds and minutes make sense as a unit value - I don't need milli-pseconds, nor hours. Is there a way restrict these available options that come from a ControlConfigurationIntent? @available(iOS 18.0, iOSApplicationExtension 18.0, *) struct TamenoFavoriteIntervalControlWidgetSetupIntent : ControlConfigurationIntent { static let title: LocalizedStringResource = "cw_FavoriteIntervalSetup" static let isDiscoverable: Bool = false @Parameter(title: "cw_IntervalParameter", defaultValue: 5.0, defaultUnit: .seconds, supportsNegativeNumbers: false) var interval: Measurement<UnitDuration>? @MainActor func perform() async throws -> some IntentResult { .result() } } I am able to restrict it just to seconds or minutes only (by adding unit: .seconds, or unit: .minutes to the @Parameter setup), but I'd really like to offer both. Thank you, Matthias

Hello, I have a customer who keeps getting an "app is damaged" error for a freshly downloaded app from the Mac App Store. The logs show the following lines: standard 12:58:40.390872+0200 storeuid Receipt Validation (at.EternalStorms.Yoink) Signature Check: PASS Bundle ID Check: PASS Bundle Version Check: PASS GUID Check: PASS Expiration Check: PASS standard 12:58:40.391649+0200 storelegacy StoreLegacy: Failed to perform in-line receipt renewal for application at path /Applications/Yoink.app : '(null)' The Mac in question is running macOS 12 Monterey - curiously, the customer has another Mac with that same system version and there it works just fine. What can be done to make this work again? Thank you, – Matthias

Hi all, with my app ScreenFloat, you can record your screen, along with system- and microphone audio. Those two audio feeds are recorded into separate audio tracks in order to individually remove or edit them later on. Now, these recordings you create with ScreenFloat can be drag-and-dropped to other apps instantly. So far, so good, but some apps, like Slack, or VLC, or even websites like YouTube, do not play back multiple audio tracks, just one. So what I'm trying to do is, on dragging the video recording file out of ScreenFloat, instantly baking together the two individual audio tracks into one, and offering that new file as the drag and drop file, so that all audio is played in the target app. But it's slow. I mean, it's actually quite fast, but for drag and drop, it's slow. My approach is this: "Bake together" the two audio tracks into a one-track m4a audio file using AVMutableAudioMix and AVAssetExportSession Take the video track, add the new audio file as an audio track to it, and render that out using AVAssetExportSession For a quick benchmark, a 3'40'' movie, step 1 takes ~1.7 seconds, and step two adds another ~1.5 seconds, so we're at ~3.2 seconds. That's an eternity for a drag and drop, where the user might cancel if there's no immediate feedback. I could also do it in one step, but then I couldn't use the AV*Passthrough preset, and that makes it take around 32 seconds then, because I assume it touches the video data (which is unnecessary in this case, so I think the two-step approach here is the fastest). So, my question is, is there a faster way? The best idea I can come up with right now is, when initially recording the screen with system- and microphone audio as separate tracks, to also record both of them into a third, muted, "hidden" track I could use later on, basically eliminating the need for step one and just ripping the two single audio tracks out of the movie and only have the video and the "hidden" track (then unmuted), but I'd still have a ~1.5 second delay there. Also, there's the processing and data overhead (basically doubling the movie's audio data). All this would be great for an export operation (where one expects it to take a little time), but for a drag-and-drop operation, it's not ideal. I've discarded the idea of doing a promise file drag, because many apps do not accept those, and I want to keep wide compatibility with all sorts of apps. I'd appreciate any ideas or pointers. Thank you kindly, Matthias

Hello, is there a way to implement Continuity Markup in our own apps? (This is what I'm talking about: https://support.apple.com/en-us/102269 , scroll down to "Use Continuity Markup"). Also, why does a QuickLook panel (QLPreviewPanel.shared()) not display the markup options when triggered from my app for png image files in my app's Group Container? Do I need to implement certain NSServicesMenuRequestor methods for that? Sadly, I could not find any docs on that. Thank you, – Matthias

I have the following code running on macOS and iOS: CKQuerySubscription *zsub = [[CKQuerySubscription alloc] initWithRecordType:ESS_CLOUDCONTROLLER_RECORDTYPE_PUSHNOTE predicate:[NSPredicate predicateWithFormat:@"TRUEPREDICATE"] subscriptionID:@"pushZSub" options:CKQuerySubscriptionOptionsFiresOnRecordUpdate|CKQuerySubscriptionOptionsFiresOnRecordCreation|CKQuerySubscriptionOptionsFiresOnRecordDeletion]; zsub.zoneID = zid; CKNotificationInfo *inf = [[CKNotificationInfo alloc] init]; inf.shouldSendContentAvailable = YES; inf.desiredKeys = @[ESS_PN_RECORDFIELD_KEY_OVERALLDATE]; zsub.notificationInfo = inf; CKModifySubscriptionsOperation *msop = [[CKModifySubscriptionsOperation alloc] initWithSubscriptionsToSave:@[zsub] subscriptionIDsToDelete:nil]; msop.qualityOfService = NSQualityOfServiceUserInitiated; msop.modifySubscriptionsCompletionBlock = ^(NSArray<CKSubscription *> * _Nullable savedSubscriptions, NSArray<CKSubscriptionID> * _Nullable deletedSubscriptionIDs, NSError * _Nullable operationError) { dispatch_async(dispatch_get_main_queue(), ^{ if (savedSubscriptions.count == 1) { //works also when already created. compH(YES, nil); } else { compH(NO, nil); } }); }; [self.database addOperation:msop]; (code synopsis: after i create a custom zone (not shown in code), I add a ckquerysubscription to it for a specific record type, configured as a silent notification) When I change the according record in my Mac app, I get an immediate silent push on iOS. On macOS, however, after I change the record in my iOS app, I don't get one. Sometimes, one silent push makes it through every now and then a minute+ late or so, and after that, it's going missing again. What's the deal? Everything's set up correctly (com.apple.developer.aps-environment is set, container-identifiers are the same, icloud services are the same, ubiquity-kvstore-identifier are the same). I obviously register for remote notifications in both apps. I see all the records and subscriptions and zones in both the Mac and iOS app. I tried setting alertBody to an empty string, or soundName to an empty string, or both to an empty string: no difference I tried having different subscriptions for my Mac and iOS app, since they use different bundle ids, but that was merged into one subscription server-side, so I'm thinking that's not it I tried making it not-silent by setting contentAvailable to NO and adding a full alertBody, title and subtitle. Again, worked on iOS, not on macOS. This has been going on since macOS 14 Sonoma (when I first got reports of this. Now running on macOS 26.3). Before Sonoma, it worked just fine. Now I thought perhaps it's because I had a subscription on the default zone, and not a custom one, so I tried subscribing to changes on a record in a custom zone (see code above), but that did not change anything either. It's all working fine, only the push notifications are not making it through to the Mac app. If I sudo killall apsd (kill the push service daemon), the last push notification suddenly miraculously makes it through, by the way. At this point, I'm out of ideas and would very much appreciate pointers as to how to debug this. Polling every 30 seconds for changes is so 1990s. Speaking of which, this is a rather long-time-running app (started in 2011). Could my CloudKit database be “too old” or “corrupted” or whatever? Thank you kindly, – Matthias
