I take that MusicKit JS is built with TypeScript, based on the attributions in the script: https://js-cdn.music.apple.com/musickit/v3/musickit.js
In the script it points to https://js-cdn.music.apple.com/musickit/v1/acknowledgements.txt – I assume this should be the v3 URL for the v3 version? It returns the same content nonetheless.
This contains attributions for TypeScript.
Currently there's a third-party effort with DefinitelyTyped, which publishes the NPM package @types/musickit-js. The latest supported version available is v1.
However, there is no version compatible with v3.
This makes it hard to use MusicKit JS v3 in a TypeScript project.
Please publish the types, ideally on the CDN along with the musickit.js file. Also consider publishing an officially Apple supported DefinitelyTyped package, or help to maintain the existing @types/musickit-js to make consuming this even easier.

getting an interesting error attempting to compile my app in Xcode 26 beta.
error: Unable to find module dependency: '_MediaPlayer_AppIntents' (in target 'icatcher' from project 'icatcher')
note: A dependency of main module 'MainModuleCrossImportOverlays' (in target 'icatcher' from project 'icatcher')
Unable to find module dependency: '_MediaPlayer_AppIntents'
Not sure what to try and pull to fix this issue
Hi,
I'm sending an API request to:
https://api.music.apple.com/v1/me/library/playlists?limit=$limit&offset=$offset
To list all of the users library playlists, however the resulting objects do not contain the playlist artwork in the JSON. I've tried adding the extend and include attributes as well but to no avail.
A partial example of the response:
{"id": PLAYLIST_ID, "type": "library-playlists", "href": "/v1/me/library/playlists/PLAYLIST_ID", "attributes": {"lastModifiedDate": "2024-09-18T20:18:24Z", "canEdit": true, "name": "Afro Party Anthems", "isPublic": false, "description": {"standard": "Definitive African party starters"}, "hasCatalog": false, "dateAdded": "2022-03-10T18:30:56Z", "playParams": {"id": PLAYLIST_ID, "kind": "playlist", "isLibrary": true}}, "relationships": {"catalog": {"href": "/v1/me/library/playlists/PLAYLIST_ID/catalog", "data": []}}}
Is there a way to get the artwork URL without sending a request for each playlist? And if not can this be fixed?
It's been an ask for a few years and I'm wondering if there are any plans, or whether the '26 SDKs/Tools allow Apple Music to work in the simulator? I develop for the Vision Pro so the usual 'fix' of running on the device is a bit of a hard ask.
At the very least a small sample library that works in the simulator would be welcome (similar to how photos works)
Cheers
It's been well over a year since Apple added favoriting of artists back to Apple Music (the little star icon on an artist page), but yet I still haven't seen a way to get this data from an authenticated user from Music API. I was expecting to hear something about this during the WWDC, but there have been no announcements that I've caught.
Has anyone else heard anything? People assume when they provide access to their Apple Music account that we can actually get to the data in their Apple Music account, and we end up looking a little dumb not being able to get this core data.
I am using https://developer.apple.com/documentation/applemusicapi/add-tracks-to-a-library-playlist
to add tracks to playlists. This endpoint works fine for all playlists except for collaborative playlists.
For collaborative playlist I get the following 500 error as a response:
"errors": [
{
"id": "<some id>",
"title": "Upstream Service Error",
"detail": "Unable to update tracks",
"status": "500",
"code": "50001"
}
]
}
Steps to reproduce:
Create a playlist in your library.
Use the api to add a song.
Confirm that it works.
Make that same playlist collaborative.
Update the playlist ID in your api request (as making a playlist collaborative changes its id)
Confirm that you get the 500 error.
Hello,
I'm new to the Swift MusicKit API and am starting with the implementation in iOS 16.
I'm getting stuck on an issue where there is no background or text color associated with the Artwork object. Is this something you have to make an additional property request for, and if so, how do you do that?
var catalogSearch = MusicCatalogResourceRequest<Album>(matching: \.id, equalTo: item.id)
let catalogResponse = try await request.response()
guard let firstItem = catalogResponse.items.first else {
return
}
In this example, firstItem.artwork only contains the url and what look like incorrect max width/height values.
here's a printout of firstItem.artwork
Optional(Artwork(
urlFormat: "musicKit://artwork/library/5F37858D-F46B-4F12-BA67-40FA8DD63D87/{w}x{h}?at=item&fat=&id=7718670444435992305&lid=5F37858D-F46B-4F12-BA67-40FA8DD63D87&mt=music&aat=Music122/v4/37/25/f5/3725f515-249f-7b91-77bb-f479cd48201c/22UMGIM32254.rgb.jpg",
maximumWidth: 0,
maximumHeight: 0
))
Hey there, I'm trying to display all user's albums using the MediaPlayer library. I'm getting many albums returning nil, but I know artwork exists because they show up in the default Music app. There doesn't seem to be much rhyme or reason for what shows up and what doesn't. All downloaded albums display artwork, but some cloud album artwork displays as well. Here's the code I'm using to debug this.
let query = MPMediaQuery.albums()
if let albumCollections = query.collections {
albums = albumCollections
}
for album in albums {
let artwork = album.representativeItem?.artwork
print(artwork, artwork?.image(at: CGSize(width: 100, height: 100)))
}
Any help would be greatly appreciated. Thanks!
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?
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 wondering if someone happened issues with currentPlaybackRate in released version of iOS 26.0?
There is no issue happened in case of iOS 18.5.
When I changed currentPlaybackRate on iOS 26.0, it seems to unexpectedly change currentPlaybackRate to be 0 or 1.0 forcibly no matter DRM or non-DRM contents. And also, playing music will be abnormal behavior and unstable with noise if currentPlaybackRate is not 1.0. And changes stop state and play state frequently.
My app has been using the iTunes Search API (itunes.apple.com/search) for a few years now, but at some point over the last week or so (late Sept. 2025) it is no longer returning track results with explicit content, regardless of whether I provide "explicit=Yes" (which is the default anyway, according to the API documentation - https://performance-partners.apple.com/search-api). Has anyone else experienced this with this API and have you figured out a workaround?
FYI, I do also use the more robust Apple Music API in another part of my app, which isn't going through this issue, so I know it's technically an alternative. I just need to stick with iTunes Search API in this particular case. Thanks.

Hi all,
Apple dropping on-going development for FireWire devices that were supported with the Core Audio driver standard is a catastrophe for a lot of struggling musicians who need to both keep up to date on security updates that come with new OS releases, and continue to utilise their hard earned investments in very expensive and still pristine audio devices that have been reduced to e-waste by Apple's seemingly tone-deaf ignorance in the cries for on-going support.
I have one of said audio devices, and I'd like to keep using it while keeping my 2019 Intel Mac Book Pro up to date with the latest security updates and OS features.
Probably not the first time you gurus have had someone make the logical leap leading to a request for something like this, but I was wondering if it might be somehow possible of shoe-horning the code used in previous versions of Mac OS that allowed the Mac to speak with the audio features of such devices to run inside the Ventura version of the OS.
Would it possible? Would it involve a lot of work? I don't think I'd be the only person willing to pay for a third party application or utility that restored this functionality.
There has to be 100's of thousands of people who would be happy to spare some cash to stop their multi-thousand dollar investment in gear to be so thoughtlessly resigned to the scrap heap.
Any comments or layman-friendly explanations as to why this couldn’t happen would be gratefully received!
Thanks,

Just wondering if anyone else is having issues with currentPlaybackRate in release version of iOS 15.4? In my particular case this is using MPMusicPlayerController.applicationQueuePlayer.
I've always had issues controlling this property reliably but from what I can see it is now completely non-operational in 15.4.
I've isolated this behavior in a trivial project, and will file a radar, but hoping others may have some insight first.
FWIW- This is my trivial test case:
class ViewController: UIViewController {
lazy var player: MPMusicPlayerApplicationController = {
let player = MPMusicPlayerController.applicationQueuePlayer
player.repeatMode = .none
player.shuffleMode = .off
player.beginGeneratingPlaybackNotifications()
return player
}()
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(forName: .MPMusicPlayerControllerPlaybackStateDidChange, object: nil, queue: .main) { [weak self] notification in
guard let notificationPlayer = notification.object as? MPMusicPlayerApplicationController,
notificationPlayer === self?.player else {
return
}
debugPrint("Player state now: \(notificationPlayer.playbackState)")
}
}
@IBAction func goAction(_ sender: Any) {
guard let item = MPMediaQuery.songs().items?.randomElement() else {
debugPrint("Unable to access media items")
return
}
debugPrint("Now playing item: \(item.title ?? "")")
player.setQueue(with: [item.playbackStoreID])
player.prepareToPlay() { error in
guard error == nil else {
debugPrint("Player error: \(error!.localizedDescription)")
return
}
DispatchQueue.main.async { [weak self] in
self?.player.play()
}
}
}
@IBAction func slowAction(_ sender: Any) {
debugPrint("Setting currentPlaybackRate to 0.5")
player.currentPlaybackRate = 0.5
checkPlaybackRate()
}
@IBAction func fastAction(_ sender: Any) {
debugPrint("Setting currentPlaybackRate to 1.5")
player.currentPlaybackRate = 1.5
checkPlaybackRate()
}
func checkPlaybackRate(afterSeconds delay: TimeInterval = 1.0) {
DispatchQueue.main.asyncAfter(deadline: .now() + delay) {
debugPrint("After \(delay) seconds currentPlaybackRate now: \(self.player.currentPlaybackRate)")
}
}
}
Typical console output:
"Now playing item: I Know You Know"
"Player state now: MPMusicPlaybackState(rawValue: 2)"
"Player state now: MPMusicPlaybackState(rawValue: 1)"
"Setting currentPlaybackRate to 1.5"
"After 1.0 seconds currentPlaybackRate now: 1.0"
"Setting currentPlaybackRate to 0.5"
"After 1.0 seconds currentPlaybackRate now: 1.0"
