Our iOS/AppleTV video content playback app uses AVPlayer to play HLS video streams and supports both custom and system playback UIs. The Fairplay content key is retrieved using AVContentKeySession. AirPlay is supported too. When the iPhone is connected to a TV through the lightning Apple Digital AV Adapter (A1438), the app is mirrored as expected. Problem: when using an iPhone or iPad on iOS 18.1.1, FairPlay-protected HLS streams are not played and a CoreMediaErrorDomain -12035 error is received by the AVPlayerItem. Also, once the issue has occurred, the mirroring freezes (the TV indefinitely displays the app playback screen) although the app works fine on the iOS device. The content key retrieval works as expected (I can see that 2 content key requests are made by the system by the way, probably one for the local playback and one for the adapter, as when AirPlaying) and the error is thrown after providing the AVContentKeyResponse. Unfortunately, and as far as I know, there is not documentation on CoreMediaErrorDomain errors so I don't know what -12035 means. The issue does not occur: on an iPhone on iOS 17.7 (even with FairPlay-protected HLS streams) when playing DRM-free video content (whatever the iOS version) when using the USB-C AV Adapter (whatever the iOS version) Also worth noting: the issue does not occur with other video playback apps such as Apple TV or Netflix although I don't have any details on the kind of streams these apps play and the way the FairPlay content key is retrieved (if any) so I don't know if it is relevant.

Hi everyone, I’ve encountered an issue with the showsPlaybackControls property in AVPlayerViewController after updating to iOS 18. Even though it’s set to true, the native playback controls (play, pause, etc.) are no longer appearing as they used to in previous iOS versions. This behavior was consistent and worked perfectly prior to iOS 18. Additionally, I’m seeing the same problem when using the VideoPlayer in SwiftUI. The native controls that should appear by default seem to have vanished after the update. Has anyone else experienced this? Is there any workaround or additional configuration required to restore the native controls? Any help or insights would be appreciated. Thanks! struct CustomPlayerView: UIViewControllerRepresentable { let player: AVPlayer func updateUIViewController(_ playerController: AVPlayerViewController, context: Context) { playerController.player = player playerController.showsPlaybackControls = true player.play() } func makeUIViewController(context: Context) -> AVPlayerViewController { return AVPlayerViewController() } }

I have an audio app that can play audio on an AirPlay device. On non-Apple TV devices, the AirPlay app (on Roku, Samsung, etc.) shows the now playing metadata: title, artist, and album art. However, on tvOS 18.1, no metadata is shown. The Apple TV device plays the audio, but there is no now playing information shown, nor any other indicators. Other media apps show the "Now Playing" controls on the upper right of the tvOS home screen. Can someone point me in the direction of how to solve this issue? I think I am missing something somewhere in regards to the tvOS metadata implementation.

Dear Apple Support, I’ve noticed an issue with the Messages app on iOS 18. When I try to send Live Photos, I select the Live Photo icon, but the photo is sent as a still image instead. Despite following the correct steps, the Live Photo feature doesn’t seem to be working properly. I would appreciate it if your team could look into this and resolve the issue in an upcoming update. Thank you for your support and continued innovation! Best regards, Erfan Nateghie

I was testing audio playback from YouTube in Safari, and the sound was clipping heavily. At first, I thought it might be due to the poor quality of my small sound system. However, when I took a screenshot and the screenshot sound effect itself produced a loud clipping noise, it became clear that this is not a mechanical problem with my speakers, nor an issue specific to YouTube or Safari. This appears to be a system-wide audio issue in macOS Tahoe 26 - Beta 5.

I am developing an app that plays HLS audio. When using AVPlayerItem with AVURLAsset, can AVAssetResourceLoaderDelegate correctly handle HLS segments? My goal is to use AVAssetResourceLoaderDelegate to add authentication HTTP headers when accessing HLS .m3u8 and .ts files. I can successfully download the files, but playback fails with errors. Specifically, I am observing the following cases: A. AVAssetResourceLoaderDelegate is canceled, and CoreMediaErrorDomain -12881 occurs In NSURLConnectionDataDelegate’s didReceiveResponse method, set contentInformationRequest In didReceiveData, call dataRequest respondWithData resourceLoader didCancelLoadingRequest is called CoreMediaErrorDomain -12881 occurs B. CoreMediaErrorDomain -12881 occurs In NSURLConnectionDataDelegate’s didReceiveResponse method, set contentInformationRequest In connection didReceiveData, buffer all received data until the end In connectionDidFinishLoading, pass the buffered data to respondWithData Call loadingRequest finishLoading CoreMediaErrorDomain -12881 occurs In both cases, dataRequest.requestsAllDataToEndOfResource is YES. For this use case, I am not using AVURLAssetHTTPHeaderFieldsKey because I need to apply the most up-to-date authentication data at the moment each file is accessed. I would appreciate any advice or suggestions you might have. Thank you in advance!

We are using a VoiceProcessingIO audio unit in our VoIP application on Mac. In certain scenarios, the AudioComponentInstanceNew call blocks for up to five seconds (at least two). We are using the following code to initialize the audio unit: OSStatus status; AudioComponentDescription desc; AudioComponent inputComponent; desc.componentType = kAudioUnitType_Output; desc.componentSubType = kAudioUnitSubType_VoiceProcessingIO; desc.componentFlags = 0; desc.componentFlagsMask = 0; desc.componentManufacturer = kAudioUnitManufacturer_Apple; inputComponent = AudioComponentFindNext(NULL, &desc); status = AudioComponentInstanceNew(inputComponent, &unit); We are having the issue with current MacOS versions on a host of different Macs (x86 and x64 alike). It takes two to three seconds until AudioComponentInstanceNew returns. We also see the following errors in the log multiple times: AUVPAggregate.cpp:2560 AggInpStreamsChanged wait failed and those right after (which I don't know if they matter to this issue): KeystrokeSuppressorCore.cpp:44 ERROR: KeystrokeSuppressor initialization was unsuccessful. Invalid or no plist was provided. AU will be bypassed. vpStrategyManager.mm:486 Error code 2003332927 reported at GetPropertyInfo

It's been well over a year since Apple added favoriting of artists back to Apple Music (the little star icon on an artist page), but yet I still haven't seen a way to get this data from an authenticated user from Music API. I was expecting to hear something about this during the WWDC, but there have been no announcements that I've caught. Has anyone else heard anything? People assume when they provide access to their Apple Music account that we can actually get to the data in their Apple Music account, and we end up looking a little dumb not being able to get this core data.

I am building an app for MacOS and I am trying to implement the code to add songs to a library playlist (which is added below). The issue I am having is that if I use Music Kit to load a users library playlists, the ID for the playlist (which is just a string of numbers) does not work with the Add tracks to a Library Playlist endpoint of Apple Music API. If I retrieve the playlists from the Apple Music API and use that playlist ID (which is different than the id I get from MusicKit) my code works fine and adds the song to the playlist. The problem is that when getting a users library playlists from Apple Music API is that it does not give me all of the library playlists that I get when using Music Kit and it also does not give me Artwork for playlists that have the collage of album covers, so I would prefer to use Music Kit to get the playlists. I have also tested trying to retrieve a single playlist using the Apple Music API with the playlist Id from Music Kit and it does not work. I get the error that the resource cannot be found. Since this is a macOs app I cannot use MusicKit to add songs to library playlists. Does anyone know a way to resolve this? Or a possible workaround? Ideally I want to use MusicKit to get the library playlists and have some way to use the playlist Id and add songs to that playlist. Below is my code for adding a song to a playlist using the Apple Music API, which works correctly only if I originally get the library playlist's id value from a playlist retrieved from the Apple Music API. Also, does anyone know why the playlist Id's are not universal and are different when using Music Kit and Apple Music API? For songs and tracks it does not seem to matter if I use music kit or Apple Music API, the Id's are in the correct format for Apple Music API to use and work with my code. Thanks everyone for any and all help! func addToPlaylist(songs: [Track], playlist: Playlist, alert: Binding<AlertItem?>) async { let tracks = AppleMusicPlaylistPostRequestBody(data: songs.compactMap { AppleMusicPlaylistPostRequestItem(id: $0.id.rawValue, type: "songs") // or "library-songs" }) let playlistID = playlist.id // Build the request URL for adding a song to a playlist guard let url = URL(string: "https://api.music.apple.com/v1/me/library/playlists/\(playlistID)/tracks") else { alert.wrappedValue = AlertItem(title: "Error", message: "Invalid URL for the playlist.") return } // Authorization Header guard let musicUserToken = try? await MusicUserTokenProvider().getUserMusicToken() else { alert.wrappedValue = AlertItem(title: "Error", message: "Unable to retrieve Music User Token.") return } do { var request = URLRequest(url: url) request.httpMethod = "POST" request.setValue("Bearer \(musicUserToken)", forHTTPHeaderField: "Authorization") request.setValue("application/json", forHTTPHeaderField: "Content-Type") let encoder = JSONEncoder() let data = try encoder.encode(tracks) request.httpBody = data let musicRequest = MusicDataRequest(urlRequest: request) let musicRequestResponse = try await musicRequest.response() // Check if the request was successful (status 201) if musicRequestResponse.urlResponse.statusCode == 201 { alert.wrappedValue = AlertItem(title: "Success", message: "Song successfully added to the playlist.") } else { print("Status Code: \(musicRequestResponse.urlResponse.statusCode)") print("Response Data: \(String(data: musicRequestResponse.data, encoding: .utf8) ??

Hello, I have followed the Creating a camera experience for the Lock Screen guide, and can now launch my app using the iPhone 16's new camera button. That said, after about 10 seconds the app is force-closed by the OS, with the only message appearing in the console: "Terminated due to signal 9". This error does not happen when: launching the app via physical camera button when device is locked launching the app by tapping the icon on the Home Screen It is only happening when: launching the app via physical camera button from the Home Screen when device is unlocked Any ideas? Thank you!

iOS 26.0 (23A5276f) – Bluetooth Call Audio Issue I’m experiencing a Bluetooth audio issue on iOS 26.0 (build 23A5276f). I cannot make or receive phone calls properly using Bluetooth devices — this affects both my car’s Bluetooth system and my AirPods Pro (2nd generation). Notably: Regular phone calls have no audio (either I can’t hear the other person, or they can’t hear me). WhatsApp and other VoIP apps work fine with the same Bluetooth devices. Media playback (music, video, etc.) works without issues over Bluetooth. It seems this bug is limited to the native Phone app or the system audio routing for regular cellular calls. Please advise if this is a known issue or if a fix is expected in upcoming beta releases.

Hi Apple Engineer, My app is using ImageCaptureCore framework to communicate to external DSLR Camera. When I connect my device to a camera, I execute the requestContentsAuthorization(completion:) to request for Access Files on Connected Cameras. This is the dialog when the request is executed: When I tap "OK", the status of content authorization keeps "Denied". even when I open "Files and Folders" permission in "Privacy & Security" Settings. When I switched ON the permission, the switch keeps back to turned off. You could see the reproduce in this GoogleDrive video https://drive.google.com/file/d/15B-R5TONgMWg8qFiYUGK0hTy62dsVGUX/view?usp=sharing The occurrence keeps happen even: I uninstall and install the app back Do "Reset Location & Privacy" Do "Reset All Settings" I attached the sysdiagnose files in this GoogleDrive file https://drive.google.com/file/d/11lovl_xC95AKXQTkZ1_e6UbEgS5md0Z3/view?usp=sharing I firstly experience this issue after researching ImageCaptureCore's API. I executed resetContentsAuthorizationWithCompletion:. After that, my permission request keeps denied as described above :( There are other developer that experiences the same as mine https://forums.developer.apple.com/forums/thread/756960 . There is a simple sample project there and it's reproducible in my case. Could you help me how to accomplished my app can be granted for permission to "Files and Folders" permission when using ImageCaptureCore? Could it be a bug from the system?

Description As of iOS 18, AVAudioSession.setPreferredIOBufferDuration ignores the requested buffer size when Sound Recognition or Vocal Shortcuts is enabled. This results in 1) much larger buffer sizes and 2) mismatched buffer sizes between input and output buffers, which causes ‘glitchy’ audio and increased latency. Additionally, when this issue occurs AVAudioSession.setPreferredIOBufferDuration continues to return ‘true’ and no error is produced. Steps to Reproduce: Enable Vocal Shortcuts on a device running iOS 18. Enable at least one shortcut (e.g. Control Center). Open or clone the example project (https://github.com/cwalo/SoundRecognitionBug) Build and install the example project Attach a headset and launch the application Observe console logs showing a requested buffer size of 0.005805 (256 samples @ 48k) an actual buffer size of 0.023220 (1104 samples @48k - this is regularly the resulting buffer size in all of our tests) Quit the app and detach the headset. Enable mutesOutput in AudioSystem.mm (to avoid feedback) Launch the application Observe Same result from step 4 Mismatched hardware buffer size of 1104 and recorded frame count of 1024 Mismatched playbackCount and recordCount Quit the app and disable vocal shortcuts Launch the app Observe IOBufferDuration matching the requested duration and matched buffer sizes (expected behavior) Expected results: Requested IOBufferDuration is respected or AVAudioSession returns false or error is produced Input and output buffer sizes match Device(s): iPhone 11 Pro, iPad Pro OS: iOS 18.0.1 Environment: Xcode 16.1 FB: FB15715421 Related to: https://forums.developer.apple.com/forums/thread/765477

Hey folks, I'm running into an odd issue suddenly with an app that had a working MusicKit integration before. I'm using ApplicationMusicPlayer to play Apple Music albums and songs. I'm testing on a physical device, signed in to Apple ID, and with a valid subscription. Apple Music via the first-party app works entirely fine on this device. Attempting to play back any content at all gives the log: <ICUserIdentityStoreACAccountBackend: 0x1070bf3e0> Failed to initialize primary apple account, error=Error Domain=ICError Code=-7013 "Client is not entitled to access account store" UserInfo={NSDebugDescription=Client is not entitled to access account store} [ICUserIdentityStore] - initializing account histories with activeAccountDSID = nil, activeLockerAccountDSID = nil, timestamp = 14605951908 [ICUserIdentityStore] Failed to fetch local store account with error: Error Domain=ICError Code=-7013 "Client is not entitled to access account store" UserInfo={NSDebugDescription=Client is not entitled to access account store}. The album artwork, track names, etc, all appear in the control center playback controls, but the music doesn't play. Trying to trigger playback with control center just results in it skipping to the next track, which doesn't play either. This exact code used to work. I have the MusicKit service selected in Apple Connect. Since this isn't entitlement-based, I'm not sure how else to check that I'm set up correctly. I've tried deleting/reinstalling the app, restarting the device, cleaning/rebuilding, and deleting DerivedData, to no avail. Any help? Running Xcode 16.4 (16F6), testing on iOS 18.5 (22F76)
