Hi All,
I am working on a DJ playout app (MACOS). The app has a few AVAudioPlayerNode's combined with the ApplicationMusicPlayer from Musickit. I can route the output of the AVaudioPlayer to a hardware device so that the audio files are directed to their own dedicated output on my Mac. The ApplicationMusicPlayer is following the default output and this is pretty annoying.
Has anyone found a solution to chain the ApplicationMusicPlayer and get it set to a output device?
Thanks
Pancras

Hello,
I am having difficulties with configuring MusicKit correctly for my web app that I am building, seeking assistance with the issues I am having. Would greatly appreciate any help!
After allowing access to the following,
"Access Request
media.mydomain.com would like to access Apple Music, media library, and listening activity for myemail'@icloud.com.",
I get a popup error that states, "Authorization failed. Please try again.".
Following is the information that is given in developer console:
[Error] Failed to load resource: the server responded with a status of 403 () (webPlayerLogout, line 0)
[Error] Authorization failed:
AUTHORIZATION_ERROR: Unauthorized
(anonymous function) (media.mydomain.com:398)
Hello!
I have a problem with getting album extended info from users library. Note that app authorised to use Apple Music according documentation.
I get albums from users library with this code:
func getLibraryAlbums() async throws -> MusicItemCollection<Album> {
let request = MusicLibraryRequest<Album>()
let response = try await request.response()
return response.items
}
This is an example of Albums request respones:

In AlbumView using task: view modifier I request extended information about the album with this code:
func loadExtendedInfo(_ album: Album) async throws -> Album {
let response = try await album.with([.tracks, .audioVariants, .recordLabels], preferredSource: .library)
return response
}
but in the response some of the fields are always nil, for example recordLabels, releaseDate, url, editorialNotes, copyright.
Please tell me what I'm doing wrong?
Hello,
I am trying to follow the getting started guide. I have produced a developer token via the music kit embedding approach and can confirm I'm successfully authorized.
When I try to do play music, I'm unable to hear anything. Thought it could be some auto-play problems with the browser, but it doesn't appear to be related, as I can trigger play from a button with no further success.
const music = MusicKit.getInstance()
try {
await music.authorize() // successful
const result = await music.api.music(`/v1/catalog/gb/search`, {
term: 'Sound Travels',
types: 'albums',
})
await music.play()
} catch (error) {
console.error('play error', error) // ! No error triggered
}
I have searched the forum, have found similar queries but apparently none using V3 of the API.
Other potentially helpful information:
OS: macos 15.1 (24B83)
API version: V3
On localhost
Browser: Arc (chromium based), also tried on Safari,
The only difference between the two browsers is that safari appears to exit the breakpoint, whereas Arc will continue (without throwing any errors)
authorizationStatus: 3
Side note, any reason this is still in beta so many years later?
I am having trouble accessing the lastPlayedData for any given album or track using MusicKit. The value is always nil, both on numerous albums and tracks I tested.
Afaik this is not a property that has to be fetched separately like tracks for example.
I am running this on my physical iPhone 12 18.1.1 with Xcode 16.1. The albums and tracks have definitely been played multiple times before. The app has permission to the library using MusicAuthorization.request()
This post mentions the same problem but offers no solution.
Thanks for any help
Hi! Im attempting to make a spotify to apple playlist converter and to do so am using the Catalog search functionality of the api. My question is, is there anyway to convert these songs to apple music urls (or ids) that does not spam api calls. I know you can batch catalog searches if you have apple music song ids, but I obviously dont have that since the song was shared from spotify. Any ideas/help is appreciated!
I have an existing Xcode project that I am trying to add MusicKit to, but for some reason I am unable to. I have logged into my developer account, and ticked off the MusicKit checkbox under the Services tab of my app in the Certificates, Identifiers & Profiles section.
In Xcode I have Automatically manage signing set to true. But MusicKit does not show up as a Capability, neither in the list of capabilities in my app, nor when trying to add it with the +Capability button. I have done this successfully before with Game Center, so I really do not understand why this does not work with MusicKit.
Any ideas as to how this can be solved?

I'm developing a Raycast extension that using Apple MusicKit API, is it safe to store developer tokens in Raycast extensions?
I can't find any way to search for a song by title only. You can search for songs, but any term you provide appears to be applied to any metadata associated with the song. Look at the largely nonsensical results when I search for a song with the letters "de":
In many cases, that string doesn't appear anywhere. I used
MusicCatalogSearchRequest(term: searchTerm, types: [Song.self])
Likewise it stands to reason that people want to search for artist and album names using text strings. How do we do that?
Hi,
I'm developing a musicKit integration in my iOS App, and I want to select songs from recently played (done it), the problem is that the queue is not auto-generated and the user have to select other song if they want to go forward.
There is any method to ask for similar songs, or recommended songs, from a song that the user has already selected?
It will be really great :)
Also if you know it... There is any publisher for the music duration or I need to do a timer?? Thanks.
David.
After an Album, Playlist, or collection of songs have been added to the ApplicationMusicPlayer queue, clearing the queue can be easily accomplished with:
ApplicationMusicPlayer.shared.queue.entries = []
This transitions the player to a paused state with an empty queue.
After queueing a Station, the same code cannot be used to clear the queue. Instead, it causes the queue to be refilled with a current and next MusicItem from the Station.
What's the correct way to detect that the ApplicationMusicPlayer is in the state where it's being refilled by a Station and clear it? I've tried the following approaches with no luck:
# Reinitialize queue
ApplicationMusicPlayer.shared.queue = ApplicationMusicPlayer.Queue()
# Create empty Queue
let songs: [Song] = []
let emptyQueue = ApplicationMusicPlayer.Queue(for: songs)
ApplicationMusicPlayer.shared.queue = emptyQueue
I am building an app for MacOS and I am trying to implement the code to add songs to a library playlist (which is added below). The issue I am having is that if I use Music Kit to load a users library playlists, the ID for the playlist (which is just a string of numbers) does not work with the Add tracks to a Library Playlist endpoint of Apple Music API. If I retrieve the playlists from the Apple Music API and use that playlist ID (which is different than the id I get from MusicKit) my code works fine and adds the song to the playlist. The problem is that when getting a users library playlists from Apple Music API is that it does not give me all of the library playlists that I get when using Music Kit and it also does not give me Artwork for playlists that have the collage of album covers, so I would prefer to use Music Kit to get the playlists.
I have also tested trying to retrieve a single playlist using the Apple Music API with the playlist Id from Music Kit and it does not work. I get the error that the resource cannot be found. Since this is a macOs app I cannot use MusicKit to add songs to library playlists.
Does anyone know a way to resolve this? Or a possible workaround? Ideally I want to use MusicKit to get the library playlists and have some way to use the playlist Id and add songs to that playlist. Below is my code for adding a song to a playlist using the Apple Music API, which works correctly only if I originally get the library playlist's id value from a playlist retrieved from the Apple Music API.
Also, does anyone know why the playlist Id's are not universal and are different when using Music Kit and Apple Music API? For songs and tracks it does not seem to matter if I use music kit or Apple Music API, the Id's are in the correct format for Apple Music API to use and work with my code. Thanks everyone for any and all help!

}
}
} catch {

}
}
Having an issue playing songs fetched with MusicKit but only on release builds, ApplicationMusicPlayer.shared.prepareToPlay() throws
"The operation couldn’t be completed. (MPMusicPlayerControllerErrorDomain error 6.)"
The authorization status is .authorized
The debug version of the app works perfectly.
Here is my project for the reference.
Thank you.

Hello,
I have a command line application that uses iTunesLibrary to "save" the state of what I have listened to. I have it run every night via a LaunchAgent. You can see the source here: https://github.com/bolsinga/itunes_json
Prior to Sequoia it would run nightly. I'd just have to grant it access to the Music library once, and it would be fine thereafter. However with Sequoia it requires UI interaction to grant it access every time. This makes it no longer run unattended overnight, defeating its purpose.
I have the console logs of when this happens. You can see it in my issue tracking it here: https://github.com/bolsinga/itunes_json/issues/410
One thing that makes me wonder is that it is a command line application, not a bundle. How do I make a command line application get access to MusicKit / iTunesLibrary, and keep it thereafter? I'd like to get my pre-Sequoia behavior back. I've filed FB15592660 too.
I've granted it access to run in the background, as well as access to my Music library (please see attached screenshots).

I'm trying to get the item that's assigned to the currentEntry when playing any song which is currently coming up nil when the song is playing. Note currentEntry returns:
MusicPlayer.Queue.Entry(id: "evn7UntpH::ncK1NN3HS", title: "SONG TITLE")
I'm a bit stumped on the API usage. if the song is playing, how could the queue item be nil?
if queueObserver == nil {
queueObserver = ApplicationMusicPlayer.shared.queue.objectWillChange
.sink { [weak self] in
self?.handleNowPlayingChange()
}
}
}
private func handleNowPlayingChange() {
if let currentItem = ApplicationMusicPlayer.shared.queue.currentEntry {
if let song = currentItem.item {
self.currentlyPlayingID = song.id
self.objectWillChange.send()
print("Song ID: \(song.id)")
} else {
print("NO ITEM: \(currentItem)")
}
} else {
print("No Entries: \(ApplicationMusicPlayer.shared.queue.currentEntry)")
}
}
I have an app that gets data from Music.app with both the iTunesLibrary and MusicKit.
iTunesLibrary has ITLibArtist.sortName and ITLibAlbum.sortTitle and ITLibAlbum.sortAlbumArtist.
I can’t seem to find an equivalent in MusicKit. How are those properties obtained using MusicKit? Thanks.
FYI I have filed FB15554956 on this. You also may see my code at https://github.com/bolsinga/itunes_json
I use Universal Product Codes (UPC) in my app to reliably identify albums after having used albumIDs for a time. AlbumIDs can change over time for no obvious reasons (see here for songIDs) so I switched to UPCs since I believed they cannot change. Well apparently they can.
A few days ago I populated a JSON with UPCs including 196871067713. Today trying to perform a MusicCatalogResourchRequest for the UPC does not return anything. When using that UPC and putting it into an Apple Music link like https://music.apple.com/de/album/folge-89-im-geistergarten/1683337782?l=en-GB redirects to https://music.apple.com/de/album/folge-89-im-geistergarten/1683337782?l=en-GB so I assume the UPC has changed from 196871067713 to 1683337782.
Apple Music can handle that and redirects to the new upc both in the app and as a website.
But a MusicCatalogResourceRequest cannot do that. I filed a suggestion for that (FB15167146) but I need a solution quicker. Can I somehow detect where the URL is redirecting to? Is there a way MusicCatalogResourceRequest can do this? Performing a MusicCatalogSearchRequest can be an option but seems unreliable when using the title as search term. Other ideas?
Thank you
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?
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)
}
}
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.
