Hi all,  Apple dropping on-going development for FireWire devices that were supported with the Core Audio driver standard is a catastrophe for a lot of struggling musicians who need to both keep up to date on security updates that come with new OS releases, and continue to utilise their hard earned investments in very expensive and still pristine audio devices that have been reduced to e-waste by Apple's seemingly tone-deaf ignorance in the cries for on-going support.  I have one of said audio devices, and I'd like to keep using it while keeping my 2019 Intel Mac Book Pro up to date with the latest security updates and OS features.  Probably not the first time you gurus have had someone make the logical leap leading to a request for something like this, but I was wondering if it might be somehow possible of shoe-horning the code used in previous versions of Mac OS that allowed the Mac to speak with the audio features of such devices to run inside the Ventura version of the OS.  Would it possible? Would it involve a lot of work? I don't think I'd be the only person willing to pay for a third party application or utility that restored this functionality. There has to be 100's of thousands of people who would be happy to spare some cash to stop their multi-thousand dollar investment in gear to be so thoughtlessly resigned to the scrap heap.  Any comments or layman-friendly explanations as to why this couldn’t happen would be gratefully received!  Thanks,  em

I am having issues deploying my iOS app, that uses ShazamKit, to get working on a Mac with Apple silicon. When uploading the archive to App Store Connect I do get ITMS-90863: Macs with Apple silicon support issue - The app links with libraries that aren’t present in macOS: /usr/lib/swift/libswiftShazamKit.dylib Is ShazamKit not supported for iOS apps that can run on Macs with Apple silicon? Or is there something I should fix in my setup / deployment?

Just wondering if anyone else is having issues with currentPlaybackRate in release version of iOS 15.4? In my particular case this is using MPMusicPlayerController.applicationQueuePlayer. I've always had issues controlling this property reliably but from what I can see it is now completely non-operational in 15.4. I've isolated this behavior in a trivial project, and will file a radar, but hoping others may have some insight first. FWIW- This is my trivial test case: class ViewController: UIViewController {     lazy var player: MPMusicPlayerApplicationController = {         let player = MPMusicPlayerController.applicationQueuePlayer         player.repeatMode = .none         player.shuffleMode = .off         player.beginGeneratingPlaybackNotifications()         return player     }()     override func viewDidLoad() {         super.viewDidLoad()         NotificationCenter.default.addObserver(forName: .MPMusicPlayerControllerPlaybackStateDidChange, object: nil, queue: .main) { [weak self] notification in             guard let notificationPlayer = notification.object as? MPMusicPlayerApplicationController,                   notificationPlayer === self?.player else {                 return             }                          debugPrint("Player state now: \(notificationPlayer.playbackState)")         }     }     @IBAction func goAction(_ sender: Any) {         guard let item = MPMediaQuery.songs().items?.randomElement() else {             debugPrint("Unable to access media items")             return         }         debugPrint("Now playing item: \(item.title ?? "")")         player.setQueue(with: [item.playbackStoreID])         player.prepareToPlay() { error in             guard error == nil else {                 debugPrint("Player error: \(error!.localizedDescription)")                 return             }             DispatchQueue.main.async { [weak self] in                 self?.player.play()             }         }     } @IBAction func slowAction(_ sender: Any) {         debugPrint("Setting currentPlaybackRate to 0.5")         player.currentPlaybackRate = 0.5         checkPlaybackRate()     } @IBAction func fastAction(_ sender: Any) {         debugPrint("Setting currentPlaybackRate to 1.5")         player.currentPlaybackRate = 1.5         checkPlaybackRate()     } func checkPlaybackRate(afterSeconds delay: TimeInterval = 1.0) {         DispatchQueue.main.asyncAfter(deadline: .now() + delay) {             debugPrint("After \(delay) seconds currentPlaybackRate now: \(self.player.currentPlaybackRate)")         }     } } Typical console output: "Now playing item: I Know You Know" "Player state now: MPMusicPlaybackState(rawValue: 2)" "Player state now: MPMusicPlaybackState(rawValue: 1)" "Setting currentPlaybackRate to 1.5" "After 1.0 seconds currentPlaybackRate now: 1.0" "Setting currentPlaybackRate to 0.5" "After 1.0 seconds currentPlaybackRate now: 1.0"

I am using the sample app from: https://developer.apple.com/videos/play/wwdc2025/277/?time=763 I installed this on an Iphone 15 Pro with iOS 26 beta 1. I was able to get good transcription with it. The app did crash sometimes when transcribing and I was going to post here with the details. I then installed iOS beta 2 and uninstalled the sample app. Now every time I try to run the sample app on the 15 Pro I get this message: SpeechAnalyzer: Input loop ending with error: Error Domain=SFSpeechErrorDomain Code=10 "Cannot use modules with unallocated locales [en_US (fixed en_US)]" UserInfo={NSLocalizedDescription=Cannot use modules with unallocated locales [en_US (fixed en_US)]} I can't continue our our work towards using SpeechAnalyzer now with this error. I have set breakpoints on all the catch handlers and it doesn't catch this error. My phone region is "United States"

Hi,Since today, we are no more able to do DELETE/PUT request on the Apple Music API.So, we can't update a playlist details, delete a playlist, delete tracks in playlist, delete tracks in library...Old methods allowed are now returning only an HTTP Code 403.Why this change in the Apple Music API ? We can hope that will be back soon ?

If I make a request to https://api.music.apple.com/v1/storefronts/us with the proper developer jwt token in the header, I receive the a successful response with a list of store fronts. If I remove the token, I do get back a 401 error. If I call any other catalog base query, I am getting back a 500 error. For instance: https://api.music.apple.com/v1/catalog/us/albums/310730204 returns a 500 error with the body being {"message":"An unexpected error occurred"} I'm not sure what I can do to fix this. Please help.

I've just begun to dip my toes into the iOS16 waters. One of the first things that I've attempted is to edit a library playlist using: try await MusicLibrary.shared.edit(targetPlaylist, items: tracksToAdd) Where targetPlaylist is of type MusicItemCollection<MusicKit.Playlist>.Element and tracksToAdd is of type [Track] The targetPlaylist was created, using new iOS16 way, here: let newPlaylist = try await MusicLibrary.shared.createPlaylist(name: name, description: description) tracksToAdd is derived by performing a MusicLibraryRequest on a specific playlist ID, and then doing something like this: if let tracksToAdd = try await playlist.with(.tracks).tracks {    // add tracks to target playlist } My problem is that when I perform attempt the edit, I am faced with a rather sad looking crash. libdispatch.dylib`dispatch_group_leave.cold.1:     0x10b43d62c <+0>:  mov    x8, #0x0     0x10b43d630 <+4>:  stp    x20, x21, [sp, #-0x10]!     0x10b43d634 <+8>:  adrp   x20, 6     0x10b43d638 <+12>: add    x20, x20, #0xfbf          ; "BUG IN CLIENT OF LIBDISPATCH: Unbalanced call to dispatch_group_leave()"     0x10b43d63c <+16>: adrp   x21, 40     0x10b43d640 <+20>: add    x21, x21, #0x260          ; gCRAnnotations     0x10b43d644 <+24>: str    x20, [x21, #0x8]     0x10b43d648 <+28>: str    x8, [x21, #0x38]     0x10b43d64c <+32>: ldp    x20, x21, [sp], #0x10 ->  0x10b43d650 <+36>: brk    #0x1 I assume that I must be doing something wrong, but I frankly have no idea how to troubleshoot this.

We are getting reports from customers that they are not able to play videos in our app after updating their phones to iOS18.3.1. (Further checking indicates that it happens on all iOS18 versions. It suddenly started occurring from February 18th, 2025) When checking logs we see that playback is failing due to CoreMediaErrorDomain error -42709. This is an undocumented error code and hence we do not know the cause of the playback issue. Does anyone know what this error code means and how the app should handle it? Reported as FB16638501.

So I've spent the last five years optimizing my video AI system so that it runs with less than 5% CPU while processing a 30fps video feed on a Macbook Pro M2, and everything is great, until Sonoma comes out, and I find myself consuming 40% CPU for the exact same workload. So I fire up Instruments, and the "heaviest stack trace" (see screenshot) turns out to be Espresso doing some completely unasked-for and absolutely useless processing on my video frames. I turn off Reactions, but nothing helps - the CPU consumptions stays at 40%. "Reactions" is nothing but a useless toy to please some WWDC keynote fanboys, I don't want it anywhere near my app or my users, and I especially do not want to take the blame for it pissing away the user's CPU cycles and battery. Now, how do I make it go away, for ever? Best regards Jacob

There are significant crash reports coming from iOS 18 users regarding AVKit framework that starts from this line [AVPlayerController _observeValueForKeyPath:oldValue:newValue:] which seems to be coming from iOS internal SDK. There are 2 kinds of crash we found: UI modification on background thread From the stack trace it seems like when AVPictureInPictureController is being deallocated and its view is being removed from superview somehow the code is being executed in background thread because there is this line there _AssertAutoLayoutOnAllowedThreadsOnly highlighted before the crash. But I’ve checked our code that plays around AVPictureInPictureController, in the locations where we would deallocate the object it will always be called on main thread which are insideviewDidLoad and deinit inside UIViewController class. From the log, it seems like the crash happened when user try to open another content when PIP player is active resulting in the current PIP instance will be replaced with a new one. My suspect is the observation logic inside AVPlayerController could be the hint to this issue, probably something broken over there since this issue happened across our app versions on iOS 18 users only. Unfortunately, I was unable to reproduce this issue yet but one of my colleagues reproduced it once but haven’t been able to do it again since. The reports keep raising each day up to 1.3k events in the last 30 days now. Over release object This one has lower reports than the first one but I decided to include it since it might have relevant information regarding the first crash since the starting stack trace is similar. The crash timing seems to be similar to the first one, where we deallocate existing AVPictureInPictureController and later replace it with a new one and also found only in iOS 18 users which also refers to [AVPlayerController _observeValueForKeyPath:oldValue:newValue:]. I also was unable to reproduce this issue so far. Oh, and both of the issues happened on both iPhone and iPad. We’d appreciate any advice on what we can do to avoid this in the future and probably any hint on why it could happened. I have reported this issue with bug number: FB15620734 I also attached one sample crash report for each of the crashes here. non ui thread access.crash over release.crash

I am trying to use the new SpeechAnalyzer framework in my Mac app, and am running into an issue for some languages. When I call AssetInstallationRequest.downloadAndInstall() for some languages, it throws an error: Error Domain=SFSpeechErrorDomain Code=1 "transcription.ar asset not found after attempted download." The ".ar" appears to be the language code, which in this case was Arabic. When I call AssetInventory.status(forModules:) before attempting the download, it is giving me a status of "downloading" (perhaps from an earlier attempt?). If this language was completely unsupported, I would expect it to return a status of "unsupported", so I'm not sure what's going on here. For other languages (Polish, for example) SpeechTranscriber.supportedLocale(equivalentTo:) is returning nil, so that seems like a clearly unsupported language. But I can't tell if the languages I'm trying, like Arabic, are supported and something is going wrong, or if this error represents something I can work around. Here's the relevant section of code. The error is thrown from downloadAndInstall(), so I never even get as far as setting up the SpeechAnalyzer itself. private func setUpAnalyzer() async throws { guard let sourceLanguage else { throw Error.languageNotSpecified } guard let locale = await SpeechTranscriber.supportedLocale(equivalentTo: Locale(identifier: sourceLanguage.rawValue)) else { throw Error.unsupportedLanguage } let transcriber = SpeechTranscriber(locale: locale, preset: .progressiveTranscription) self.transcriber = transcriber let reservedLocales = await AssetInventory.reservedLocales if !reservedLocales.contains(locale) && reservedLocales.count == AssetInventory.maximumReservedLocales { if let oldest = reservedLocales.last { await AssetInventory.release(reservedLocale: oldest) } } do { let status = await AssetInventory.status(forModules: [transcriber]) print("status: \(status)") if let installationRequest = try await AssetInventory.assetInstallationRequest(supporting: [transcriber]) { try await installationRequest.downloadAndInstall() } } ...

Hello, I am having difficulties with configuring MusicKit correctly for my web app that I am building, seeking assistance with the issues I am having. Would greatly appreciate any help! After allowing access to the following, "Access Request media.mydomain.com would like to access Apple Music, media library, and listening activity for myemail'@icloud.com.", I get a popup error that states, "Authorization failed. Please try again.". Following is the information that is given in developer console: [Error] Failed to load resource: the server responded with a status of 403 () (webPlayerLogout, line 0) [Error] Authorization failed: AUTHORIZATION_ERROR: Unauthorized (anonymous function) (media.mydomain.com:398)

Hi all, I'm working on an audio visualizer app that plays files from the user's music library utilizing MediaPlayer and AVAudioEngine. I'm working on getting the music library functionality working before the visualizer aspect. After setting up the engine for file playback, my app inexplicably crashes with an EXC_BREAKPOINT with code = 1. Usually this means I'm unwrapping a nil value, but I think I'm handling the optionals correctly with guard statements. I'm not able to pinpoint where it's crashing. I think it's either in the play function or the setupAudioEngine function. I removed the processAudioBuffer function and my code still crashes the same way, so it's not that. The device that I'm testing this on is running iOS 26 beta 3, although my app is designed for iOS 18 and above. After commenting out code, it seems that the app crashes at the scheduleFile call in the play function, but I'm not fully sure. Here is the setupAudioEngine function: private func setupAudioEngine() { do { try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default) try AVAudioSession.sharedInstance().setActive(true) } catch { print("Audio session error: \(error)") } engine.attach(playerNode) engine.attach(analyzer) engine.connect(playerNode, to: analyzer, format: nil) engine.connect(analyzer, to: engine.mainMixerNode, format: nil) analyzer.installTap(onBus: 0, bufferSize: 1024, format: nil) { [weak self] buffer, _ in self?.processAudioBuffer(buffer) } } Here is the play function: func play(_ mediaItem: MPMediaItem) { guard let assetURL = mediaItem.assetURL else { print("No asset URL for media item") return } stop() do { audioFile = try AVAudioFile(forReading: assetURL) guard let audioFile else { print("Failed to create audio file") return } duration = Double(audioFile.length) / audioFile.fileFormat.sampleRate if !engine.isRunning { try engine.start() } playerNode.scheduleFile(audioFile, at: nil) playerNode.play() DispatchQueue.main.async { [weak self] in self?.isPlaying = true self?.startDisplayLink() } } catch { print("Error playing audio: \(error)") DispatchQueue.main.async { [weak self] in self?.isPlaying = false self?.stopDisplayLink() } } } Here is a link to my test project if you want to try it out for yourself: https://github.com/aabagdi/VisualMan-example Thanks!

I am trying to Build server for testing on Linux(Alma linux 9 VM) NAME="AlmaLinux" VERSION="9.7 (Moss Jungle Cat)" ID="almalinux" ID_LIKE="rhel centos fedora" VERSION_ID="9.7" PLATFORM_ID="platform:el9" PRETTY_NAME="AlmaLinux 9.7 (Moss Jungle Cat)" ANSI_COLOR="0;34" [azuki@AlmaDevVM ~]$ uname -m x86_64 I have tried the following steps: Before starting, ensured that Swift 6 installed. Referred https://www.swift.org/install/ for instructions. Build the library In Terminal, uses the following commands to compile the Swift library: cd Development/Key_Server_Module/Swift swift build -Xbuild-tools-swiftc -DTEST_CREDENTIALS After building the library, ran test cases to ensure the library behaves as expected. ALL unit tests are passing with the development credentials. • Since I was using an x86_64 machine: export LD_LIBRARY_PATH=./Sources/prebuilt/x86_64-unknown-linux-gnu/ Run all tests: swift test -Xbuild-tools-swiftc -DTEST_CREDENTIALS --disable-swift-testing Build the server Build the server: Apache Before starting, ensured the following: a. Installed Apache HTTPD and the dev tools. Using the following command for installation: yum install httpd httpd-devel redhat-rpm-config b. After this, integrated it into the Apache server environment with swift library that was built above. Used the following command to build the server using apxs: • Since I was using an x86_64 machine: apxs -i -a -c -Wl,-L${PWD}/.build/x86_64-unknown-linux-gnu/debug/ -Wl,-lswift_fpssdk -Wl,-L${PWD}/Sources/prebuilt/x86_64-unknown-linux-gnu -lfpscrypto -Wl,-R${PWD}/.build/x86_64-unknown-linux-gnu/debug server_setup/mod_fps.c c. Next, copied the dependent libraries to the Apache modules folder using these commands: • If using an x86_64 machine: cp Sources/prebuilt/x86_64-unknown-linux-gnu/libfpscrypto.so /usr/lib64/httpd/modules/libfpscrypto.so cp .build/x86_64-unknown-linux-gnu/debug/libswift_fpssdk.so /usr/lib64/httpd/modules/libswift_fpssdk.so d. Configuring Apache HTTPD Configured Apache HTTPD by adding the module and handler to your Apache HTTPD configuration (/etc/httpd/conf/httpd.conf). Note that the apxs command may automatically add the LoadModule line in the previous step. Listen 8080 LoadFile /usr/lib64/httpd/modules/libfpscrypto.so LoadFile /usr/lib64/httpd/modules/libswift_fpssdk.so LoadModule fps_module /usr/lib64/httpd/modules/mod_fps.so <Location "/fps"> SetHandler fps_handler Copy the credentials to the Apache modules folder. cp -r ../credentials /usr/lib64/httpd/modules/ export FPS_CERT_PATH= /usr/lib64/httpd/modules/credentials/test_certificates.json e. Run your server You can run the Apache HTTPD server with the configured module by using the following command: httpd -D FOREGROUND No issues see till step. Get SDK version [azuki@AlmaDevVM Key_Server_Module]$ curl localhost:8080/fps/v 26.0.0 But when i try to generate license [azuki@AlmaDevVM Key_Server_Module]$ curl -d ../Test_Inputs/iOS/spc_ios_hd_lease_2048.json localhost:8080/fps {"fairplay-streaming-response":{"create-ckc":[{"id":1,"status":-42601}]}} Can you please suggest what i might be missing here?

Where can I find the documentation of the Genlock feature of the iPhone 17 Pro? How does it work and how can I use it in my app?

We observed that the PHPicker is unable to load RAW images captured on an iPhone in some scenarios. And it is also somehow related to iCloud. Here is the setup: The PHPickerViewController is configured with preferredAssetRepresentationMode = .current to avoid transcoding. The image is loaded from the item provider like this: if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage) { itemProvider.loadFileRepresentation(forTypeIdentifier: kUTTypeImage) { url, error in // work } } This usually works, also for RAW images. However, when trying to load a RAW image that has just been captured with the iPhone, the loading fails with the following errors on the console: [claims] 43A5D3B2-84CD-488D-B9E4-19F9ED5F39EB grantAccessClaim reply is an error: Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application." UserInfo={NSUnderlyingError=0x2804a8e70 {Error Domain=NSCocoaErrorDomain Code=4097 "connection from pid 19420 on anonymousListener or serviceListener" UserInfo={NSDebugDescription=connection from pid 19420 on anonymousListener or serviceListener}}} Error copying file type public.image. Error: Error Domain=NSItemProviderErrorDomain Code=-1000 "Cannot load representation of type public.image" UserInfo={NSLocalizedDescription=Cannot load representation of type public.image, NSUnderlyingError=0x280480540 {Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application."

We think it is related to iCloud Photos: On the device that has iCloud Photos sync enabled, the picker is able to load the image right after it was synced to the cloud. On devices that don't sync the image, loading always fails. It seems that the sync process is doing some processing (?) of the image that will later enable the picker to load it successfully, but that's just guessing. Additional observations: This seems to only occur for images that were taken with the stock Camera app. When using Halide to capture RAW (either ProRAW or RAW), the Picker is able to load the image. When trying to load the image as kUTTypeRawImage instead of kUTTypeImage, it also fails. The picker also can't load RAW images that were AirDroped from another device, unless it synced to iCloud first. This is reproducable using the Selecting Photos and Videos in iOS sample code project. We observed this happening in other apps that use the PHPicker, not just ours. Is this a bug, or is there something that we are missing?

when I get results from picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) and I load the image using itemProvider .loadFileRepresentation (the itemProvider is the NSItemProvider provided by the PHPickerResult) will the url that's returned by this method be guaranteed to have the file extension ie, "file://image.jpeg" not "file://image" I want to know if i need to just check the extension to know its file type. (FYI in case this makes a difference, im only interested in user screenshots and screenrecordings)

Dear Sirs, I'd like to add an icon to my audio driver based on AudioDriverKit. This icon should show up left of my audio device in the audio devices dialog. For an Audio Server Plugin I managed to do this using the property kAudioDevicePropertyIcon and CFBundleCopyResourceURL(...) but how would you do this with AudioDriverKit? Should I use IOUserAudioCustomProperty or IOUserAudioControl and how would I refer to the Bundle? Is there an example available somewhere? Thanks and best regards, Johannes
