I am trying to get the playbackStoreID via the MPMediaPickerController so I can play songs in my app. For many songs I can see and select I am getting a value of "0" for the playbackStoreID on the returned MPMediaItem. Now if I use the "Music" app I can play those songs, but since the playbackStoreID is "0" I cannot successful get them in the queue for a MPMusicPlayerController.applicationQueuePlayer What's the deal? How do I get a proper ID that I can use to get those songs played? If I cannot, how can I hide those songs from the MPMediaPickerController so a user does not think they can play those songs in my app?

Hello everyone! Im new to this forum and i have a question about playing mp3 files on our Homepage on apple devices: We have a service section with the latest News, Traffic and Weather on our Site. The problem is, that the mp3 Files can be played, but the player shows 0:00 and is not able to go to the middle or end of the file. This is ONLY on Iphone in our app and on Safari. I am recording the mp3 with ffmpeg. The strange thing is, that there is no Bitrate shown in FIle details, and also no length. The File is auto Recorded with a script.

Hello, Can we use below mentioned keys in our code :- _MRMediaRemotePlayerPlaybackStateDidChangeNotification kMRMediaRemotePlaybackStateUserInfoKey Thanks

We are looking at potentially adding access to Apple Music Classical into a game we have with classical music. I cannot find any documentation that states if MusicKit can access the subscription content on Apple Music Classical. We would prefer to give our players the option to play with the higher quality subscription music if desired. Thank you in advance for your assistance.

Has anyone found a way to retrieve user token if I want to make an app on Flutter that uses that to make Apple Music API calls to just retrieve the user data and display it on the application? Something like when a user opens their app, there is a button that says connect with apple. It takes the user to give permissions for apple music and that retrieves their user token. I know there is Music Kit on Swift but i wonder if there is something like that on flutter

In SwiftUI there is a built-in component for displaying album artworks called Artwork but there is no equivalent for UIKit. My current approach is to use the .url() method to read image's URL and download the image or read it from the disk but the performance is much worse than it was previously with MPMediaItem's artworkImage method. let artworkQueue = DispatchQueue( label: "MusicKit-ArtworkQueue", qos: .default, attributes: .concurrent ) let artworkSemaphore = DispatchSemaphore(value: 5) extension Song { func artworkImage(for size: CGSize, completion: @escaping (UIImage?) -> Void) { artworkQueue.async { artworkSemaphore.wait() defer { artworkSemaphore.signal() } let imageURL = artwork?.url( width: Int(size.width), height: Int(size.height) ) // I hate doing this as it might very well break in the future guard let imageURL, imageURL.scheme == "musicKit" else { return completion(nil) } guard let imageData = try? Data(contentsOf: imageURL), let image = UIImage(data: imageData) else { return completion(nil) } completion(image) } } } I really dislike this approach because it feels hacky but somewhat works. You might ask what's the semaphore for? Well, without it I could notice that MusicKit was choking and after reading too many artworks at once. Can someone from Apple please provide us with an example on how to use MusicKit with UIKit properly? Ideally (IMO) we would have a method defined on Song and other MusicKit structures that returns the image for us, just like MPMediaItem had the .artwork() method. It would make our lives so much easier.

Some users of our app get a black screen when playing mp4 files on their phones. The users are all running iOS 17.3.1 and cannot catch the error message when playing a black screen. The user can play the video normally after restarting the mobile phone. However, we want to solve this problem from the code. We use two Avplayers to complete the sequential playback of multiple videos. override init(frame: CGRect) { super.init(frame: frame) layer.addSublayer(videoPlayerA) layer.addSublayer(videoPlayerB) } lazy var layers = [videoPlayerA, videoPlayerB] lazy var videoPlayerA: AVPlayerLayer = { let avPlayerLayer = AVPlayerLayer(player: AVPlayer()) avPlayerLayer.contentsScale = UIScreen.main.scale avPlayerLayer.videoGravity = .resizeAspectFill return avPlayerLayer }() lazy var videoPlayerB: AVPlayerLayer = { let avPlayerLayer = AVPlayerLayer(player: AVPlayer()) avPlayerLayer.contentsScale = UIScreen.main.scale avPlayerLayer.videoGravity = .resizeAspectFill return avPlayerLayer }() func play() { if let path = paths[safe: currentIndex] { currentVideoPath = path currentPlayer = AVPlayer(playerItem: AVPlayerItem(url: URL(fileURLWithPath: path))) layers.first?.player?.pause() layer.insertSublayer(layers.first ?? AVPlayerLayer(), below: layers.last) layers.swapAt(0, 1) layers.first?.player = currentPlayer layers.first?.player?.play() SHPlayerGlobalStatus.sharedInstance.isLocalPlayerPlaying = true try? AVAudioSession.sharedInstance().setCategory(.playback) try? AVAudioSession.sharedInstance().setActive(true) }

I have an image viewing app with support for avif (and avis) images. I'm trying to figure out if the recent bug in CoreMedia (dav1d) affects my app. The apple security update: https://support.apple.com/en-gb/HT214097 The vulnerable code path in dav1d is only reached when c->n_fc > 1 (https://code.videolan.org/videolan/dav1d/-/blob/2b475307dc11be9a1c3cc4358102c76a7f386a51/src/decode.c#L2845), where c is the dav1d context. With some reverse engineering, the way I see CMPhoto calling into VideoToolBox (which internally calls into AV1SW.videodecoder, which is a wrapper around dav1d), the max frame delay is hardcoded to 1 in the dav1d settings which intern means that c->n_fc in dav1d is always 1. The vulnerable code path in dav1d is only reached when c->n_fc > 1 (https://code.videolan.org/videolan/dav1d/-/blob/2b475307dc11be9a1c3cc4358102c76a7f386a51/src/decode.c#L2845). From my understand, this should mean that my app isn't affected. The apple security update however clearly mentions that "Processing an image may lead to arbitrary code execution". Surely I'm missing something?

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

Could some tell what the relevant endpoint is for fetching all public list of a user playlist. I am able to fetch a one via the id but i want to fetch all in a single request without using authorization.

I have the conflict when i use replaykit. There is other app or system use the recording. I want my app can recognize them and let them use the replaykit preferentially.

Is it possible to edit the Grouping of a song from the user's library using the Apple Music API? According to what I read from the documentation, this is not possible, but this is something that I really would love, so, I better ask. Thanks in advanced!

I have old ScreenCaptureKit sample downloaded on Oct 2022. That sample worked on Oct 2022. But it does not work on Apr 2024 on Sonoma 14.4.1 M1 MacBook. It only shows black screen. I also download updated ScreenCaptureKit sample and test it. It works on Sonoma 14.4.1 M1 MacBook. I noticed latest sample have SCContentSharingPicker and other changes. I have my screen capture application based on old ScreenCaptureKit sample. My app only shows black screen. Do I have to add SCContentSharingPicker and SCContentSharingPickerObserver on my application for capturing screen on Sonoma? Old way of screen capture without SCContentSharingPicker is not supported anymore on Sonoma?

I am using MusicKit ApplicationMusicPlayer to play music in my app. Everything works fine as long as I'm not playing large playlists that contain hundreds of songs. When I to play collection of songs that is larger than around 300 I'm always getting the error message saying: "Prepare to play failed" UserInfo={NSDebugDescription=Prepare to play failed, NSUnderlyingError=0x121d42dc0 {Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Remote call timed out" UserInfo={NSDebugDescription=Remote call timed out}}})) It doesn't matter if songs are downloaded to the device or not. I am aware that there is another initializer for player's queue that accepts Playlist instances but in my app users can choose to sort playlist tracks in different order than the default and that makes using that initializer not feasible for me. I tried everything I could think of, I tried to fall back on MPMusicPlayerController and pass array of MPMusicPlayerPlayParameters to it but the result was the same. typealias QueueEntry = ApplicationMusicPlayer.Queue.Entry let player = ApplicationMusicPlayer.shared let entries: [QueueEntry] = tracks .compactMap { guard let song = $0 as? Song else { return nil } return QueueEntry(song) } Task(priority: .high) { [player] in do { player.queue = .init(entries, startingAt: nil) try await player.play() // prepareToPlay failed } catch { print(error) } }
