I am trying to offer my users a wide variety of playlists, like Apple Music does in the "explore" section. I fetched the charting playlists for the current storefront, but that's as far as I get. For example, I fetch the top charts genres first. If a user selects a genre I want to display the playlists for this genre, so I call the charts endpoint with the genre as the id but I can't get a response. path = "/v1/catalog/\(storefrontID)/charts" components.queryItems = [ URLQueryItem(name: "types", value: "playlists"), URLQueryItem(name: "chart", value: "most-played") ] if let id = id { let genreQuery = URLQueryItem(name: "genre", value: id) components.queryItems?.append(genreQuery) } Even weirder, I get exactly one genre "Musik" (which isn't a genre) with identifier "34" and storefrontId "de" where it works and I get my playlists. All other genre return empty responses. I try to use AppleMusic API with MusicKit as an addition, but there doesn't seem to be a solution for this problem either.

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.

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?

In my Developer account under Certificates, Identifiers &amp; Profiles --&gt; Keys, I cannot add the "Media Services (MusicKit, ShazamKit) key. I have an app identifier where the "MusicKit" App Service is selected. How can I get the key to be available for this app?

Hello everyone! I am using the web version of the Apple Music Kit API, and similar to how Apple is able to produce a user's year in rewind playlist showing the most played artists/songs from a year, I am trying to replicate it for either a year or all time. I have been searching the internet for days trying to figure it out, but I've been completely stuck. I am able to make the following HTTP request successfully. GET https://api.music.apple.com/v1/me/library/songs/ which returns back the user's library of songs, but I haven't figured out how to get the play count. I have tried adding a query like such ?extend=playCount, but that doesn't work. I can see here that the Swift Music Kit API is able to extend a play count property, but I haven't been able to figure it out for Web. Ideally, I am looking for an endpoint that just shows a user's top artist/tracks similar to Spotify, however, whenever I try to use the heavy in rotation endpoint here, it always returns an empty array. The way that I have described is the long-roundabout way where I'll have to fetch each individual song and sort by playCount. But if anyone happens to know how I can do either of the options I've described, it will be truly appreciated ! I've seen other forums posts from years ago, but hopefully there's been a discovered way. Thank you!

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. However, I do have sets of 10 artists that work fine. Anyone know why?

Hi, I’m looking at using MusicKit in my watchOS app however I don’t seem to have any method of being able to play the audio though the recommended use of MPMusicPlayerController since it isn’t available on watchOS. This method works fine for iOS and iPadOS but not watchOS which seems bizarre considering we have full access to MusicKit but no way to actually play any audio. I’m trying to build an app that includes Apple Music through MusicKit but don’t have any way to actually play the audio. Is there a technical reason for this and if so is there any other way to play audio from MusicKit on watchOS. The docs for MPMusicPlayerController can be found here: https://developer.apple.com/documentation/mediaplayer/mpmusicplayercontroller

Hi, . As my understading, I know that id: MusicItemID The unique identifier for the song. Threfore, I want to try to retreive the specific song I want by using MusicItemID : let request = MusicCatalogResourceRequest<Song>(matching: \.id, equalTo: //MusicItemID) let response = try await request.response() guard let song = response.items.first else { return } However, where can I find the MusicItemID for the song I want ? Thank you so much

Is there a way to get the user name after login if I use Apple Music Kit JS or using the APIs? Or can I use the music token from Apple Music kit JS with Apple Sign In to get a user name? Greetings

I've been continuing to port my app to the Mac using Catalyst, and have discovered a couple of big issues with MusicLibraryRequest which make it not particularly usable. I've submitted FBs already, but figured a forum post wouldn't hurt :) filter(matching:) functions unavailable on macOS/Catalyst - FB12301718 The first thing I noticed when building for a macOS or Catalyst target is that a couple of functions are simply not available: I'm hoping this is a bug, as these methods are crucial to being able to interact with the library. request.filter(matching: .id, equalTo:) always returns empty on Mac Catalyst - FB12301908 I have not been able to successfully retrieve an Album using a MusicLibraryRequest. The result is always empty. In the feedback, I attached a sample project that makes an unfiltered MusicLibraryRequest, then takes the first album and tries to make a new MusicLibraryRequest filtered to that album's ID. Fetching albums by ID using this method works just fine on iOS 17. Thanks again for all your work on bringing these capabilities to the Mac!

I'm getting the following error in Xcode and I can't figure out how to fix it. Cannot load underlying module for 'MediaPlayer' I've searched Google and have come across lots of other people with similar issues whereby they're importing something and it's producing this error alongside it. https://stackoverflow.com/questions/76256875/cannot-load-underlying-module-for-scenekit https://developer.apple.com/forums/thread/115059 https://stackoverflow.com/questions/32673866/cocoapods-cannot-load-underlying-module-for-x The error is being shown inline with this bit of code: import SwiftUI import MusicKit import MediaPlayer <-- this line here I can build and run the project without issue and it disappears. But will quickly reappear again a short while later and it's very annoying. How can I resolve this please?

Hi, My app hangs for about a second when I open the app when it's been in background phase. It doesn't hang every time, but it hangs randomly (like once in 10 times) when I open the app again. I am not able to reproduce what causes this hang. Hang Detection provides hang logs (spindump) when hang occurs. It has something to do with MusicKit as logs mention it but I cannot understand what it is. Please help me understand these logs. I am running iOS 17 beta 1 with MusicKit and ApplicationMusicPlayer.

I'm currently working on integrating MusicKit into my app and would like to provide a seamless user experience by displaying only the songs that are available in the user's region or country. However, after going through the MusicKit documentation, I couldn't find a direct method to determine song availability based on the user's location. I wanted to inquire if there is a way to determine if a specific song or a catalog of songs is available in the user's region or country using MusicKit. It would be incredibly helpful if someone could guide me on how to achieve this or provide any insights on alternative approaches. Thank you in advance for your assistance!

If a user has only added one song from an album in its library, the library album endpoint (/me/library/albums) will return this album. It does not make sense because the user did not add the full album to its library, only one song. Note that the Apple Music app is doing the same in its Library > Albums section. How to retrieve only those albums which have been added ?

Planning to create a Music Game App similar to Guitar Hero kind of, and I am planning to use songs from beginner producers (They don't have any Publishers or Distributors). If I get their legal concent through a contract to use their songs, does Apple allow to have Music that is not from Itunes if I get the legal license from the producer to use their songs in my app? Will apple allow songs that don't have Publishers or Distributors, or in the App review stage they will flag it and cause an issue for me?

Hi, Is there any reasonable way to use MusicKit on the Vision Pro simulator. I have been unable to get anything working and I was wondering if the situation is the same as iOS etc where you need a physical device to test the app.

I imported the MediaPlayer framework and used MPMusicPlayerPlayParameters in my SwiftUI project. While the app is launching, If the app is built by Xcode 14.3.1 or a newer version, it instantly crashes on a simulator or on a real device. This problem persists on iOS 16.0 to 16.4. (I haven't tried iOS 15 or below) I also tried to build and run the app with Xcode 15 - beta 4 however it still crashes. Because of this reason, I archive and submit to App Store with Xcode 14.2. (the built made by Xcode 14.2 works perfectly!!) Here is the error message: dyld[17235]: Symbol not found: _$sSo27MPMusicPlayerPlayParametersCSe05MediaB0Mc Referenced from: <77FEF170-9C51-3580-8F8B-2ADD2F1B3FD1> /Users/[UserName]/Library/Developer/CoreSimulator/Devices/72CE26D8-4DD4-4319-B0C7-DE52D6645875/data/Containers/Bundle/Application/C808623F-5372-40F0-907F-E86E12AE6EDD/[AppName].app/[AppName] Expected in: <06F636E1-695C-34F1-809D-7CA24F67AFE9> /Library/Developer/CoreSimulator/Volumes/iOS_20B72/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.1.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/MediaPlayer.framework/MediaPlayer I believe this is Apple related issue however if there is any way that can fix the issue, please let me know.

I have noticed changes Apple Music made to my library, take in particular a changed album edition that is reflected in how the title is listed. I can see the new title in the Music app in two different devices. On one device MPMediaQuery returns the album with the new title. The other device (an iPad with less memory, in case that matters) is still returning the old edition. Is there anything I can do to make sure the data returned is up to date and matches what is seen in the Music app?

I'm building a UIKit app that reads user's Apple Music library and displays it. In MusicKit there is the Artwork structure which I need to use to display artwork images in the app. Since I'm not using SwiftUI I cannot use the ArtworkImage view that is recommended way of displaying those images but the Artwork structure has a method that returns url for the image which can be used to read the image. The way I have it setup is really simple: extension MusicKit.Song { func imageURL(for cgSize: CGSize) -> URL? { return artwork?.url( width: Int(cgSize.width), height: Int(cgSize.height) ) } func localImage(for cgSize: CGSize) -> UIImage? { guard let url = imageURL(for: cgSize), url.scheme == "musicKit", let data = try? Data(contentsOf: url) else { return nil } return .init(data: data) } } Now, everytime I access .artwork property (so a lot of times) the main thread gets blocked and the console output gets bombared with messages like these: 2023-07-26 11:49:47.317195+0200 Plum[998:297199] [Artwork] Failed to create color analysis for artwork: <MPMediaLibraryArtwork: 0x289591590> with error; Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.mediaartworkd.xpc was invalidated: failed at lookup with error 159 - Sandbox restriction."

I am not planning to use it anywhere and if so it should be a computed async property so it doesn't block the caller. I know I can move the call to a background thread and that fixes the issue of blocking main thread but still the loading times for each artwork are terribly slow and that impacts the UX. SwiftUI's ArtworkImage loads the artworks much quicker and without the errors so there must be a better way to do it.

Hi team, Are there any plans to update the Apple Music SDK for Android? With the upcoming release of the new music experience on iOS and the Apple Music app for Android getting a whole slew of features over the past month, is the (rather out of date - last update was December 2021) MusicKit SDK for Android going to get the new release that would enable developer avail of the new feature or is that SDK abandoned at this stage?
