I'm trying to set a specific start time for the song, using ApplicationMusicPlayer.shared.playbackTime but is not working musicPlayer.playbackTime = 10 try await musicPlayer.prepareToPlay() try await musicPlayer.play()

Good morning, I'm trying to use MusicKit functionalities in order to get last played songs and put them into a local DB, to be played later. Following the guide on developer.apple.com, I created the required AppServices integration: Below is a minimal working version of what I'm doing: func requestMusicAuthorization() async { let status = await MusicAuthorization.request() switch status { case .authorized: isAuthorizedForMusicKit = true error = nil case .restricted: error = NSError(domain: "Music access is restricted", code: -10) case .notDetermined: break case .denied: error = NSError(domain: "Music access is denied", code: -10) @unknown default: break } } on the SwiftUI ContentView there's something like that: .onAppear { Task { await requestMusicAuthorization() if MusicManager.shared.isAuthorizedForMusicKit { let response = try await fetchLastSongs() do { let request = MusicRecentlyPlayedRequest<Song>() let response = try await request.response() var songs: [Song] = response.items.map { $0 } // do some CloudKit handling with songs... print("Recent songs: \(songs)") } catch { NSLog(error.localizedDescription) } } } } Everything seems to works fine, but my console log is full of garbage like that: MSVEntitlementUtilities - Process MyMusicApp PID[33633] - Group: (null) - Entitlement: com.apple.accounts.appleaccount.fullaccess - Entitled: NO - Error: (null) Attempted to register account monitor for types client is not authorized to access: {( "com.apple.account.iTunesStore" )} is there something I'm missing on? Should I ignore that and go forward with my implementation? Any help is really appreciated.

1 . I have recently downloaded iOS 18 and my phone is on dark mode but on somethings, things are on white / light mode. Is there any way too fix this? I’ll post some screen shots showing my problem.

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 trying to use the Speech Synthesizer to speak the pronunciation of a word in British English rather than play a local audio file which I had before. However, I keep getting this in the debugger: #FactoryInstall Unable to query results, error: 5 Unable to list voice folder Unable to list voice folder Unable to list voice folder IPCAUClient.cpp:129 IPCAUClient: bundle display name is nil Unable to list voice folder Here is my code, any suggestions?? ` func playSampleAudio() { let speechSynthesizer = AVSpeechSynthesizer() let speechUtterance = AVSpeechUtterance(string: currentWord) // Search for a voice with a British English accent. let voices = AVSpeechSynthesisVoice.speechVoices() var foundBritishVoice = false for voice in voices { if voice.language == "en-GB" { speechUtterance.voice = voice foundBritishVoice = true break } } if !foundBritishVoice { print("British English voice not found.

As the summer continues, I have been diving deeper and deeper into MusicKit, largely with great results. A few issues have arisen that I've outlined here, feedbacks already filed and numbers included here. All of this happens on the lasted developer beta and latest Xcode beta. Thanks! FB10967343 - Setting the queue with library and non-library items at the same time doesn't work correctly In my app, I am working on a feature that lets a user shuffle songs from a collection of albums that may or may not be in their library. However, I’ve discovered an issue where the queue does not seem to work correctly when mixing these types. I’ve attempted to load ApplicationMusicPlayer by creating a Queue and to load applicationQueuePlayer using a MPMusicPlayerPlayParametersQueueDescriptor, but the same issue occurs each time. The queue is able to play songs from the same source, but if it’s been playing a library song and tries to move to a non-library song, the queue stops.  The first thing I do is pick random songs from each album, using a MusicLibraryRequest or a MusicCatalogResourceRequest as appropriate, then taking a randomElement() from the ensuing MusicItemCollection for the album.  I append each track to an array, which I then cast to MusicItemCollection so I’ve now got a MusicItemCollection consisting of the tracks I want. If I’m in MusicKit land, I simply set the queue as follows:  player.queue = ApplicationMusicPlayer.Queue(for: tracks) It takes a bit more doing in MediaPlayer, but in theory this should also work, right?    do {         let paramObjects = tracks.compactMap {             $0.playParameters         }         let params = try paramObjects.map({try JSONEncoder().encode($0)}) let dicts = try params.compactMap {               try JSONSerialization.jsonObject(with: $0, options: []) as? [String:Any]           }           let finalParams = dicts.compactMap {                 MPMusicPlayerPlayParameters(dictionary: $0)             } let descriptor = MPMusicPlayerPlayParametersQueueDescriptor(playParametersQueue: finalParams) mediaPlayer.setQueue(with: descriptor) } catch { print(error) } In either case, the following issue occurs: say that I end up with a queue made up of one library song, then one non-library song. The player will play just the first song, then it acts as if the queue has ended. Say that it has two non-library songs, then one library song. Just the two non-library songs play. Indeed, printing queue.entries shows just the number of items that were from the same source type. FB10967076 - Publishing changes from background thread error when inserting queue items When using the .insert method on ApplicationMusicPlayer.Queue on the last iOS 16 and Xcode betas, it returns a “Publishing changes from background thread” error even though the function I’m doing in is marked as a @MainActor and the stacktace indicates it was on the main thread. FB10967277 - song.with([.albums], preferredSource: .library) generates thousands of lines of EntityQueries in the console I’ve noticed that when using the preferredSource: .library when requesting additional properties on a library item creates ~6,000 of “EntityQuery” entries in the console, all in the span of a second. This doesn’t seem to be leading to any major performance issues, but it sure seems like something isn't right. let request = MusicLibraryRequest<Song>.init() do { let response = try await request.response() guard let song = response.items.first else { return } let songWithAlbums = try await song.with([.albums], preferredSource: .library) } catch { print(error) } generates the following output (except... 6,000 of them) 2022-07-31 13:02:07.729003-0400 MusicKitFutzing[9405:2192606] [EntityQuery] Finished fetching results in 0s 2022-07-31 13:02:07.729047-0400 MusicKitFutzing[9405:2192605] [EntityQuery] Finished executing query in 0.00100017s 2022-07-31 13:02:07.729202-0400 MusicKitFutzing[9405:2192611] [EntityQuery] Finished executing query in 0s 2022-07-31 13:02:07.729240-0400 MusicKitFutzing[9405:2192605] [EntityQuery] Finished fetching results in 0s

Hi, Is it possible to get the various audio variants for a given song ID, I am unable to find any documentation for this online. In particular, could I see if Dolby Atmos is available for the track? Here is an example of a request I am sending: https://api.music.apple.com/v1/catalog/us/songs/1168770969

I have an IOSurface and I want to turn that into a CIImage. However, the constructor of CIImage takes a IOSurfaceRef instead of a IOSurface. On most platforms, this is not an issue because the two types are toll-free bridgeable... except for Mac Catalyst, where this fails. I observed the same back in Xcode 13 on macOS. But there I could force-cast the IOSurface to a IOSurfaceRef: let image = CIImage(ioSurface: surface as! IOSurfaceRef) This cast fails at runtime on Catalyst. I found that unsafeBitCast(surface, to: IOSurfaceRef.self) actually works on Catalyst, but it feels very wrong. Am I missing something? Why aren't the types bridgeable on Catalyst? Also, there should ideally be an init for CIImage that takes an IOSurface instead of a ref.

I am looking to do the OOB (Out of band) pairing using QR code with a device from iOS app. I referred the documentation but could not find if this is feasible or not. Few forum says it is not feasible, few says it is. May I know the latest state from Apple development support team?

Hello Apple, I am concerned about the new iOS Screen Mirroring that is available on iOS. I have an app that is only meant to be viewed on iPhones (not Macs or Computers, due to security reasons. I am assuming that Screen Mirroring is using AirPlay underneath, otherwise is there an API being planned or coming that can disable this functionality or is there a way for my app to opt out out of iOS Screen Mirroring? Thanks.

Hello everyone, I am thrilled about the iPhone Mirroring demo on WWDC24 and I have a few thoughts to share. Will it work through a local network, or can the iPhone be accessed within a global network? Will there be an API to initiate iPhone mirroring via an app? This would be a great feature for MDMs, allowing administrators to provide support for their users. Could you share more details from the development perspective?

Hi everyone, I'm currently developing an iOS app using React Native and recently got accepted into the Apple Music Global Affiliate Program. To fully utilize this opportunity, I need to implement the following functionalities: Authorize Apple Music usage Play Apple Music within my app Identify if a user has an Apple Music subscription Initiate and complete Apple Music subscription within my app I've successfully implemented the first three functionalities using the react-native-apple-music module. Now, I need your help to understand how I can directly trigger the Apple Music subscription process from within my app. Thank you for your help!

Hello, this is building off of another post in which several other posters and I had already attempted solving the issue in hacky ways. I am using MPMusicPlayerController.applicationQueuePlayer. My end goal here is to dynamically add items to the queue when it has ended based on my application's business logic. There is no way for me to know what these items will be when I am initially setting the queue. I have an updated implementation that seems to cover most edge cases, except for a glaringly obvious one – if there is just one item in the queue, and the user skips the track via MPRemoteCommandCenter (eg. lock screen), then it does not work. Currently, when I receive a MPMusicPlayerControllerPlaybackStateDidChange notification, I run this block: if player.playbackState == .paused,            player.currentPlaybackTime == 0,            player.indexOfNowPlayingItem == 0 {             EndOfQueueManager.handle()         } In the absence of a mechanism to detect the end of the queue from the framework, I would love to add the ability to add a target to MPRemoteCommand, like you can do for AVPlayer. I have tried to do exactly that, but it does not work: MPRemoteCommandCenter.shared().nextTrackCommand.addTarget { (event) -> MPRemoteCommandHandlerStatus in         if queue.count == 1 {             EndOfQueueManager.handle() }         return .success } I already have a functioning AVPlayer implementation that achieves my goal without any compromises or edge cases. I would be very disappointed if there is no way to do this with MPMusicPlayerController – being notified about the queue ending feels like a fairly rudimentary API hook.

Hello, I am wondering how one can play music videos (with the actual video playing) with the ApplicationMusicPlayer using MusicKit for Swift? There is not much documentation on this, so any help would be appreciated.

I'm working on a macOS application that captures audio and video. When the user selects a video capture source (most likely an elgato box), I would like the application to automatically select the audio input from the same device. I was achieving this by pairing video and audio sources that had the same name, but this doesn't work when the user plugs in two capture devices of the same make and model. With the command system_profiler SPUSBDataType I can list all the USB devices, and I can see that the two elgato boxes have different serial numbers. If I could find this serial number, then I could figure out which AVCaptureDevices come from the same hardware. Is there a way to get the manufacturer's serial number from the AVCaptureDevice object? Or a way to identify the USB device for an AVCaptureDevice, and from there I could get the serial or some other unique ID?

Hello, currently working on a shareplay feature that allows users to pull 3d models from icloud and view it via volumes/immersive space on the vision pro. Was able to get the sharing working with multiple windows recently so now all that's left is to be able to sync/share the model in the SharePlay session. As I understand it, we should generally use GroupSessionMessenger for commands and light data like model positioning/syncing properties. Whereas for bigger pieces of data (images/videos/models), we should send these through GroupSessionJournal which the group session manages and syncs it for all users in the call. I have a button to get the current user's model data and add it to the journal via /// modelData is type `Data` try await journal.add(modelData) I have also set up a task to observe/receive updates to the journal's attachments in when receiving a group session. for await groupSession in MyModelActivity.sessions() { ... tasks.insert { Task { for await attachments in journal.attachments { for attachment in attachments { do { let modelData = try await attachment.load(Data.self) // throws error here - `notSupported` let modelUrl = writeModelDataToTempDirectory(modelData: modelData) self.modelUrlToLoadForGroupSession = modelUrl } catch let error { print("Error: \(error)") } } } } } } Not quite sure why I'm running into an error being thrown when attempting to load the attachment data on the other devices, any thoughts? The documentation for add(_:) and load(_:) say that the attachment should conform to Transferable but Data.Type should already conform to Transferable

Hello, We've a music app reading MPMediaItem. We got items using MPMediaQuery. But we realized that some downloaded tracks from Apple Music were fetched too. Not all downloaded track but only those who were played recently. Of course, since these tracks are protected with DRM we can't play them in our player. It's weird to get them in our query because we added predicate in order to dont fetch protected asset and iCloud item MPMediaPropertyPredicate(value: false, forProperty: MPMediaItemPropertyHasProtectedAsset) MPMediaPropertyPredicate(value: false, forProperty: MPMediaItemPropertyIsCloudItem) To be sure, we made a second check on each item we've fetched extension MPMediaItem { public func isValid() -> Bool { return self.assetURL != nil && !self.isCloudItem && !self.hasProtectedAsset } } But we still get these items. Their hasProtectedAsset attribute always return false. I dont know if it's a bug, but since we can't detect this items as Apple Music downloaded track, we can't either: filter them to not add them in our application library OR switch on a MPMusicPlayerController.applicationMusicPlayer to allow the user to play them

We have an app with a broadcast extension with a RPBroadcastSampleHandler. The implementation is working fine, however for quite some users the extension suddenly crashes during the broadcast. The stacktrace stacktrace of the crashing thread always looks like the shortened sample below. (Full crash reports and stack traces are attached to the submitted Feedbacks.) Looking at the stacktrace none of our code is running, just ReplayKit code handling XPC messages at that moment: Thread: #0 0x00000001e2cf342c in __pthread_kill () #1 0x00000001f6a51c0c in pthread_kill () #2 0x00000001a1bfaba0 in abort () #3 0x00000001a9e38588 in malloc_vreport () #4 0x00000001a9e35430 in malloc_zone_error () [...] #18 0x0000000218ac91bc in -[RPBroadcastSampleHandler processPayload:completion:] () #19 0x0000000198b81360 in __NSXPCCONNECTION_IS_CALLING_OUT_TO_EXPORTED_OBJECT_S2__ () Is anyone aware of there issues with ReplayKit? Are there known workarounds? Could anything we're doing affect crashes like this?
