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.

Hello, Problem I am having the exact same issue as described here : https://forums.developer.apple.com/forums/thread/693310 From my understanding of the answers on this topic, it appears to be a problem on the Server Side.

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

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.

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

Hi, is there a way to display the animated cover art in an app? Not every album has a cover art but for the ones that have one I would like to display them instead of the artwork. Thank you :)

I'm getting a variety of errors when I call prepareToPlay on the MPMusicPlayerController. Sometimes they happen, sometimes they don't. I'm trying to play songs from the Apple Music service. When I don't get the errors, it plays just fine. I have iOS v13.5.1 on my iPhone Xs and I'm using Xcode 11.5. This is my code: let applicationMusicPlayer = MPMusicPlayerController.applicationMusicPlayer applicationMusicPlayer.setQueue(with: [trackID]) applicationMusicPlayer.prepareToPlay(completionHandler:{ error in if let error = error { print(error.localizedDescription) return } DispatchQueue.main.async{ applicationMusicPlayer.play() } } These are the various errors I'm getting: [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=2 "Queue was interrupted by another queue" UserInfo={NSDebugDescription=Queue was interrupted by another queue} [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Preparing queue timed out" UserInfo={NSDebugDescription=Preparing queue timed out} [SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=6 "Failed to prepare to play" UserInfo={NSDebugDescription=Failed to prepare to play} [SDKPlayback] applicationQueuePlayer _establishConnectionIfNeeded timeout [ping did not pong]

I was about to finally sign up for the Apple Music affiliate program since one of my apps does provide the MusickKit Subscription Offer. However, it looks like it was renamed and restricts usage to only artists and record labels. (https://partners.applemediaservices.com) Is this correct? Can I as an indie developer not earn commission of Apple Music that I drive from my apps?

After thoroughly scouring the internet numerous times, I came to the realization that Apple has not documented their User Authentication flow. Instead, developers are often directed to use their JavaScript solution, which proves to be insufficient and impractical for many projects. Could we please request a comprehensive documentation outlining the process of generating a Music User Token from the Developer Token? This would greatly benefit developers seeking to integrate Apple Music functionality into their projects.

Hello everyone, my name is Joshua Osagie. For 2 months now, I have been trying to build my own music application, but unfortunately, I can’t because I was thinking I would get an API from maybe Apple Music or Spotify that will grant me access to over 100 million music. Even if the API is paid for, I have been doing my research, but then it's kind of impossible. So please, if anyone has an idea on what I can do to bring this application to life, I will really appreciate it. Or if anyone could share me an idea on how to get over millions of music on my app, I will be really grateful.

I often find when doing basic actions in MusicKit it is incredibly slow compared to Apple's Music App. I've tried different versions, devices, networks, Apple's sample code, it all throughout the last several years, and it is all the same. Does anyone else have this issue?

Hello, I am working on the Musickit web browser application. I have created my developer token as mentioned in the documentation. When I call the authorize() method to authenticate, I get the Apple Music pop up as expected. However, after entering the user credentials and "allowing" access, I get the following error: POST https://play.itunes.apple.com/WebObjects/MZPlay.woa/wa/webPlayerLogout 403 (Forbidden) musickit.js:28 Uncaught (in promise) AUTHORIZATION_ERROR: Unauthorized at https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:269512 at Generator.next () at asyncGeneratorStep$u (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:266594) at _next (https://js-cdn.music.apple.com/musickit/v3/musickit.js:28:266821) I am using an user account with paid subscription to Apple Music. With the JWT created, I am able to make API calls and receive the response for requests that do that need the userToken. I am currently stuck at this step and would like some help to root cause this issue.

I can not find an album where isCompilation is true, even when the album clearly consists of "songs by various artists". For example: Album( id: "567979803", title: "Earth's Answer", artistName: "Brian Keane, Deuter, James Newton, ,...many more", isCompilation: false The compilation checkbox for this album in the Apple Music Catalog Get Info dialog is also not checked. Is this field NEVER SET in the catalog or the MusicKit API? If there IS an album where isCompilation is true, I'd like its ID to use for a test case. If not, can this be added to the API?

The MusicKit JS V3 documentation has this article about Native WebViews. For some reason, my app fails to do anything after musicKitInstance.authorize() is called. I think that it is not being recognized as a WebView and is trying to open the window as if it was running in a browser, but since it's not a browser, there's no way for it to open a browser window. Is there something I can do to make this work? I have tried many things, including setting the user agent to a few different ones for web views and seeing if it behaves differently but didn't see any different behavior. Is there something musickit.js checks for, when determining if it's running in a WebView, that I can leverage to ensure the Native WebView workflow is followed?

Is there a way to retrieve a list of all the favorited artists for a given user via the Apple Music API? I see endpoints for playback history and resources added to the library. But I want to retrieve the full list of favorited artists for the given user and I don't see any obvious choices in the documentation. Thanks in advance!

I have an app that allows users to send messages to each other via a link. I'm receiving many requests from my users to add songs. Can I use the Apple Music API to add 30-second song previews along with the user's message? If users want to listen to the full song, there will be a link to the full song on Apple Music. My app contains ads and subscriptions.

My app is consistently crashing for a specific user on 14.3 (iMac (24-inch, M1, 2021) when their library is being retrieved in full.

This is the code making the call: var request = MusicLibraryRequest<Album>() request.limit = 10000 let response = try await request.response() I’m aware of a similar (?) crash FB13094022 (https://forums.developer.apple.com/forums/thread/736717) that was claim fixed for 14.2.
