Running in a Mac (Catalyst) target or Apple Silicon (designed for iPad). Just accessing the playbackStoreID from the MPMediaItem shows this error in the console: -[ITMediaItem valueForMPMediaEntityProperty:]: Unhandled MPMediaEntityProperty subscriptionStoreItemAdamID. The value returned is always “”. This works as expected on iOS and iPadOS, returning a valid playbackStoreID. import SwiftUI import MediaPlayer @main struct PSIDDemoApp: App { var body: some Scene { WindowGroup { Text("playbackStoreID demo") .task { let authResult = await MPMediaLibrary.requestAuthorization() if authResult == .authorized { if let item = MPMediaQuery.songs().items?.first { let persistentID = item.persistentID let playbackStoreID = item.playbackStoreID // <--- Here print("Item \(persistentID), \(playbackStoreID)") } } } } } } Xcode 15.1, also tested with Xcode 15.3 beta 2. MacOS Sonoma 14.3.1 FB13607631

I filed FB13689023 for this since it is clearly unexpected. Non Apple Music library tracks are not returned on macOS using MusicLibraryRequest. I tried querying by artist where I only get Apple Music tracks, and by id where I don't get the track. On iPhone and iPad I was able to get both AM and non-AM tracks, that's how I got a valid id to try on macOS. Sync Library is on. The build targets My Mac (Designed for iPad). I'm using Xcode 15.3 and I'm on Sonoma (14.4). Any help is appreciated...

Is it possible to notify my fileprovider extension to pre-load folders recursively from a given starting point ? I am currently doing this externally from user space with a thread that crawls through the folder tree but wondering if there is a better way.

I am trying to take a screenshot of each running window on the screen independently (even if not in the foreground). I am using SCScreenshotManager's captureImageWithFilter and SCContentFilter's initWithDesktopIndependentWindow. When I do this for every SCWindow in SCShareableContent's windows, I do get all the actual windows, but also get many mostly blank windows or windows that no ordinary user would consider to be an actual window. These include dozens of windows with no title, some with "Focus Proxy" title, some for menu bar icons, the wallpaper, the desktop icons, etc. I've implemented a naive solution that filters all windows that have no title, owningApplications with no title or bundle ID in a hardcoded blocklist (e.g. "com.apple.controlcenter", "com.apple.wallpaper.agent") and that helps, but is far from robust and is naturally fragile. Is there a recommended way to distinguish actual application windows or an overall better approach here? Thanks!

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()

Hi there, I have a related forum thread here and a Feedback Assistant ticket open, but this issue seems different. Sometime within the last 2-3 weeks, code related to MusicLibrary has stopped working. None of my code has changed. For example, the below two snippets used to work fine:  for track in newTracks {    try await MusicLibrary.shared.add(track, to: targetPlaylist)  } try await MusicLibrary.shared.edit(targetPlaylist, items: items) newTracks and items are both fetched using: try await targetPlaylist.with(.tracks, preferredSource: .catalog).tracks Using preferredSource: .catalog was a workaround used to address the issue in the aforementioned post above. All iOS 16 capable functions are decorated with: @available(iOS 16, *) or in an if block: if #available(iOS 16, *) {... What's happening is that the following is showing up in the console: 2022-11-28 23:31:11.279648+0700 MyApp[38653:6736450] [core] Attempted to register account monitor for types client is not authorized to access: {(     "com.apple.account.iTunesStore" )} 2022-11-28 23:31:11.279718+0700 MyApp[38653:6736450] [Default] <ICUserIdentityStoreACAccountBackend: 0x282adb520> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" 2022-11-28 23:31:11.279758+0700 MyApp[38653:6736450] [Default] ICUserIdentity - Unable to retrieve DSID for userIdentity=<ICUserIdentity 0x2806eb120: [Active Account: <unresolved>]> - error=Error Domain=com.apple.accounts Code=7 "(null)" These errors are not caught by a do/catch block, but I assume they are related to the issue, and I believe they have to do with MyApp trying to access things that Music Kit thinks it's not supposed to. For example, if MyApp attempts to work with a playlist that it did not create, errors would be expected, thrown errors. The thing is that I know I'm working with resources that are created by MyApp. In fact, in trying to test this, I just tried to create a playlist with the below, and the same behavior is occurring: @available(iOS 16, *) func createPlaylist2(name: String, description: String) async -> MusicKit.Playlist? {     do {         Logger.log(.info, "Creating Playlist: \(name)")         Logger.log(.shrug, "Does this work?")         let newPlaylist = try await MusicLibrary.shared.createPlaylist(name: name, description: description) // <= Things stop here!         Logger.log(.success, "New playlist created: \(newPlaylist)") // <= this isn't logged.         return newPlaylist // <= nothing is returned     } catch {         Logger.log(.error, "Could not create new playlist: \(error)") // <= no error logged.     }     return nil } The result is: 2022-11-29 00:15:01.875064+0700 MyApp[38794:6760471] [core] Attempted to register account monitor for types client is not authorized to access: {(     "com.apple.account.iTunesStore" )} 2022-11-29 00:15:01.875372+0700 MyApp[38794:6760471] [Default] <ICUserIdentityStoreACAccountBackend: 0x283005720> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" 2022-11-29 00:15:01.876677+0700 MyApp[38794:6760323] [EntityQuery] Finished executing query in 0.000999928s 2022-11-29 00:15:01.889055+0700 MyApp[38794:6760323] [EntityQuery] Finished fetching results in 0.0120001s 2022-11-29 00:15:01.891235+0700 MyApp[38794:6760329] [core] Attempted to register account monitor for types client is not authorized to access: {(     "com.apple.account.iTunesStore" )} 2022-11-29 00:15:01.891684+0700 MyApp[38794:6760329] [Default] <ICUserIdentityStoreACAccountBackend: 0x283005720> Failed to register for account monitoring. err=Error Domain=com.apple.accounts Code=7 "(null)" 📘 Creating Playlist: TEST PLAYLIST 🤷🏻‍♀️ Does this work? 2022-11-29 00:15:06.697374+0700 MyApp[38794:6760329] [] nw_path_necp_check_for_updates Failed to copy updated result (22) What's really nasty is that errors are not thrown, so they can't be caught and handled in a catch block.

Any help would be most appreciated. @JoeKhun: Did I miss the memo?

When I connect my MacBook to my living room AirPort (older gen wallwart) via Music app, the music output in both rooms is synced. When I try to setup a Multi-Output Device in AudioMidi setup, I'm not able to get them synced. I'm outputting to the same devices, they're all on the same sample rate, and I've played with the various settings (Primary Clock Source and Drift Sync). What gives? How are these connections different? Intel MacBook Pro 2018 running Sonoma 14.5

I am capturing a screenshot with SCScreenshotManager's captureImageWithFilter. The resulting PNG has the same resolution as the PNG taken from Command-Shift-3 (4112x2658) but is 10x larger (14.4MB vs 1.35MB). My SCStreamConfiguration uses the SCDisplay's width and height and sets the color space to kCGColorSpaceSRGB. I currently save to file by initializing a NSBitmapImageRep using initWithCGImage, then representing as PNG with representationUsingType NSBitmapImageFileTypePNG, then writeToFile:atomically. Is there some configuration or compression I can use to bring down the PNG size to be more closely in-line with a Command-Shift-3 screenshot. Thanks!

Is there a way to get the current queue items from an MPMusicPlayerController? I need to know when the items I've set to the queue finish playing completely but cannot find any way to do this. I am not using MusicKit but setting the queue via play parameters. From what I can tell so far, after the queue finishes playing, it pauses and resets to the first item in the queue. So even after playback is done, there is no way to know that it finished on its own.

So i meant to make a shared album but made a shared library. That being said, I deleted the shared album but my family can not remove it from the phones

I'm using the systemMusicPlayer to play music and want to update the playback time using addObserver forKeyPath. [self setMusicPlayer: [MPMusicPlayerController systemMusicPlayer]]; I've tried these two methods: [self addObserver:self forKeyPath:@"musicPlayer.currentPlaybackTime" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:&musicPlayer]; [self.musicPlayer addObserver:self forKeyPath:@"currentPlaybackTime" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:&musicPlayer]; I do get the initial values for currentPlaybackTime in: -(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context but I never get any calls when the player is playing the song (the whole point). If I set the currentPlaybackTime to a specific value (locating manually using a slider), I get calls with the values I set (useless since I know what I am setting them to). How are we supposed to track the playback time without just polling it constantly?

Since iOS 12 it has become difficult to detect the end of playback using the system music player. In earlier iOS versions, the now playing item would be set nil and you would receive a notification that the player stopped. In iOS 12 and later, nowPlayingItem still contains the current song and the only notification you get is MPMusicPlayerControllerPlaybackStateDidChangeNotification with the playbackState set to MPMusicPlaybackStatePaused. Pressing pause in my car (or any remote access) generates the same conditions making it difficult to correctly detect the difference. It would be nice if they added a notification that playback was done (similar to the other players). Any suggestions?

Under Sonoma 14.4 the compression option doesn't work with PNG images. It works for JPG/HEIF. Preview can export PNG file to HEIC with compression option. What am I missing? Previously this has worked. I am trying with 0.01 and 0.9 as compression quality and the file size is the same for PNG. Is Preview using some trick to convert the image using ciContext.createCGImage? PS: Compression option of 1.0 was broken under 14.4 RC and Preview created empty file. func heifImageDataUsingDestination(at url: URL, compressionQuality : CGFloat) -> Data? { guard let imageSource = CGImageSourceCreateWithURL(url as CFURL, nil) else { return nil } guard let cgImage = CGImageSourceCreateImageAtIndex(imageSource, 0, nil) else { return nil } var mutableData = NSMutableData() guard let imageDestination = CGImageDestinationCreateWithData(mutableData, "public.heic" as CFString, 1, nil) else { return nil } let options = [ kCGImageDestinationLossyCompressionQuality: compressionQuality ] as CFDictionary CGImageDestinationAddImage(imageDestination, cgImage, options) let success = CGImageDestinationFinalize(imageDestination) if success { return mutableData as Data } return nil } func heifImageDataUsingCIContext(at url: URL, compressionQuality : CGFloat) -> Data? { guard let ciImage = CIImage(contentsOf: url) else { return nil } let context = CIContext() let colorspace = ciImage.colorSpace ?? CGColorSpaceCreateDeviceRGB() let options = [CIImageRepresentationOption(rawValue: kCGImageDestinationLossyCompressionQuality as String) : compressionQuality] return context.heifRepresentation(of: ciImage, format: .RGBA8, colorSpace: colorspace, options: options) }

How we can implement music kit in flutter app?

I'm trying to generate a developer token with the following code in nodeJS: const jwt = require('jsonwebtoken') const {TEAM_ID, KID, APPLE_PRIVATE_KEY } = require('./secret') const expiration = 36000; const currentTime = Math.floor(Date.now() /1000); const expirationTime = currentTime + expiration; const options = { algorithm: 'ES256', header :{ alg : "ES256", kid : KID } } const payload = { iss : TEAM_ID, iat : currentTime, exp : expirationTime } const newToken = jwt.sign(payload, APPLE_PRIVATE_KEY, options) console.log('1111111111111111111111' , newToken) When testing my newToken in curl -- I'm getting a 401 response.

Hey, I've been trying to fetch my Apple Music recently played songs for an app I'm working on, and I want to access the lastPlayedDate field. If I'm not mistaken, this field should exist for a Song according to Apple's documentation: https://developer.apple.com/documentation/musickit/song/lastplayeddate However, whenever I try to fetch this data, the lastPlayedDate field is always nil. All the other data I'm looking for, however, seems to fetch without issue. Here's the code I'm using: //Request as described in Apple MusicKit //https://developer.apple.com/documentation/musickit/musicrecentlyplayedrequestable var request = MusicRecentlyPlayedRequest<Song>() request.limit=30 do { let response = try await request.response() let songs = response.items.compactMap { song -> RecentlyPlayedSong? in let songName = song.title let songArtist = song.artistName let songAlbum = song.albumTitle let artwork: MusicArtworkType let preview_url = song.previewAssets?.first?.url?.absoluteString if let appleMusicArtwork = song.artwork { print("Found a song, \(song) with lastPlayedDate \(song.lastPlayedDate)") artwork = .AppleMusic(appleMusicArtwork) return RecentlyPlayedSong(name: songName, artist: songArtist, album: songAlbum, artwork: artwork, preview_url: preview_url, lastPlayedDate: song.lastPlayedDate ?? Date()) } I'm trying to map the response into a custom struct I made, but here's a sample of what's getting printed to the logs: Found a song, Song(id: "1676362342", title: "pwdr Blu (feat. Brother.)", artistName: "Kx5, deadmau5 & Kaskade") with lastPlayedDate nil Found a song, Song(id: "881289980", title: "Worlds Apart (feat. Kerli)", artistName: "Seven Lions") with lastPlayedDate nil Found a song, Song(id: "1501540431", title: "What’s Done Is Done", artistName: "Seven Lions & HALIENE") with lastPlayedDate nil Even though I just listened to these songs a a few minutes ago. Anyone ever run into this issue before? Any settings I need to look at changing to get this to show?

I'm making a request to get 10 artists with their top songs at once, but for some artists it will always fail with a 504. The response is also in HTML which leads to a decoding error. This is my code var request = MusicCatalogResourceRequest<Artist>(matching: \.id, memberOf: ids) request.properties = properties let response = try await request.response() where ids is MusicItemId. Below I have an input which will always fail 100% of the time, even when retried. 10 elements  - 0 : "51639"  - 1 : "331584"  - 2 : "120199"  - 3 : "45058"  - 4 : "284786497"  - 5 : "44984"  - 6 : "37299"  - 7 : "518462"  - 8 : "39525"  - 9 : "73568" Example response: [DataRequesting] Failed to parse body of response with status code Unknown (504):  <!DOCTYPE html> <html lang="en"> <head>   <style>     body {       font-family: "Helvetica Neue", "HelveticaNeue", Helvetica, Arial, sans-serif;       font-size: 15px;       font-weight: 200;       line-height: 20px;       color: #4c4c4c;       text-align: center;     }     .section {       margin-top: 50px;     }   </style> </head> <body> <div class="section">   <h1>&#63743;</h1>   <h3>Gateway Timeout</h3>   <p>Correlation Key: WFRI6Q5HXAUJYXGNRKQ6YTBYIM</p> </div> </body> </html> I have also tried batching these into 2 requests of 5 artists instead of 1 request of 10 artists which still fails.
