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:

📘 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.
I know that iOS 16.1 got released around the end of October, but I really don't know what's going on here.
The behavior is showing up in both prod and when testing locally.
Any help would be most appreciated.
@JoeKhun: Did I miss the memo?
