Use MusicKit's User Library Artists with Catalog Artists?
When making a call to https://api.music.apple.com/v1/me/library/artists to get a user's library artists, it returns the following (as an example): [ { id: 'r.FCwruQb', type: 'library-artists', href: '/v1/me/library/artists/r.FCwruQb?l=en-US', attributes: { name: 'A Great Big World' } }, { id: 'r.7VSWOgj', type: 'library-artists', href: '/v1/me/library/artists/r.7VSWOgj?l=en-US', attributes: { name: 'Aaliyah' } }, ... ] If I try and use an artist id from that retuned data to look up additional information about the artist by calling https://api.music.apple.com/v1/catalog/us/artists/{id}, it fails. User Library Artists don't seem to equal Catalog Artists. It'd be great if there was a way to use these interchangeably. Am I missing something?

Can individual Apple Developer accounts stream full tracks with MusicKit?
I have implemented fetching Apple Music preview songs using a Swift framework integrated into a Unity app. My requirement is to fetch full tracks from a user’s Apple Music library and play them inside Unity. To do this, I understand that I need to handle authentication, generate a Developer Token, and then obtain a Music User Token to access the user’s Apple Music content. Currently, I have an Individual Apple Developer account (not Organization). Based on my research, it seems that: With an Individual account, I can implement this functionality and even upload builds to TestFlight for internal testing. However, when releasing the app publicly on the App Store, full-track playback may be restricted for Individual accounts and allowed only for Organization accounts. 👉 Can you confirm if this understanding is correct? 👉 Specifically, is it possible for an Individual account to fetch and play full-length tracks from a subscribed Apple Music user’s library (at least for internal/TestFlight testing)?

401 Unauthorized when attempting to access Apple Music Feed API
Hello, I am trying to access the Apple Music Feed API, but I am recieving a 401 Unauthorized error message whenever I try to access it. I have tried using my own code to generate a JWT and directly call the API (which can call the standard Apple Music API successfully). > GET /v1/feed/song/latest HTTP/2 > Host: api.media.apple.com > user-agent: insomnia/2023.5.8 > authorization: Bearer [REDACTED] > accept: */* < HTTP/2 401 < content-type: application/json; charset=utf-8 < content-length: 0 < x-apple-jingle-correlation-key: AV5IOHBNM2UUJVOFQ4HZ2TGF6Q < x-daiquiri-instance: daiquiri:10001:daiquiri-all-shared-ext-7bb7c9b9bb-r459v:7987:25RELEASE91:daiquiri-amp-kubernetes-shared-ext-ak8s-prod-pv4-amp-daiquiri-ingress-prod and also the Apple provided Python example code, which gives me authentication errors too. $ python3 ./apple_music_feed_example.py --key-id NMBH[...] --team-id 3TNZ[...] --secret-key-file-path "/Users/foxt/Documents/am-feed/NMBH[...].p8" --out-dir . running....

MPNowPlayingInfoCenter playbackState fails to update after losing audio focus on macOS
My Environment: Device: Mac (Apple Silicon, arm64) OS: macOS 15.6.1 Description: I'm developing a music app and have encountered an issue where I cannot update the playbackState in MPNowPlayingInfoCenter after my app loses audio focus to another app. Even though my app correctly calls [MPNowPlayingInfoCenter defaultCenter].playbackState = .paused, the system's Now Playing UI (Control Center, Lock Screen, AirPods controls) does not reflect this change. The UI remains stuck until the app that currently holds audio focus also changes its playback state. I've observed this same behavior in other third-party music apps from the App Store, which suggests it might be a system-level issue. Steps to Reproduce: Use two most popular music apps in Chinese app Store (NeteaseCloud music and QQ music) (let's call them App A and App B): Start playback in App A. Start playback in App B. (App B now has audio focus, and App A is still playing). Attempt to pause App A via the system's Control Center or its own UI. Observed Behavior: App A's audio stream stops, but in the system's Now Playing controls, App A still appears to be playing. The progress bar continues to advance, and the pause button becomes unresponsive. If you then pause App B, the Now Playing UI for App A immediately corrects itself and displays the proper "paused" state. My Questions: Is there a specific procedure required to update MPNowPlayingInfoCenter when an app is not the current "Now Playing" application? Is this a known issue or expected behavior in macOS? Are there any official workarounds or solutions to ensure the UI updates correctly?

Clarification on SFSpeechRecognizer system alert message and service URLs for whitelisting
Hello Apple Engineers, I am developing a feature related to SpeechRecognizer (import Speech), and I have two questions: After adding the NSSpeechRecognitionUsageDescription key in my Info.plist, when I initialize an SFSpeechRecognizer instance, the system shows an authorization alert. The alert contains a pre-defined message from Apple: “Speech data from this app will be sent to Apple to process your requests. This will also help Apple improve its speech recognition technology.” Is it possible to remove or customize this message? My app runs in a network environment with a whitelist. I need to know which URL the SFSpeechRecognizer instance connects to, and which port it uses, so that I can add it to the whitelist. Thank you very much for your support! Best regards, Yu Cheng

ShazamKit for Android and 16 KB native library alignment
Hello, I'm working on a Flutter app targeting both Android and iOS, where I implemented ShazamKit. In order to achieve that, I first tried with the flutter_shazam_kit package, but since it's not maintained anymore, I forked it here, and tried to update it to meet the Google Play Store requirements, as you can see here: https://github.com/mregnauld/flutter_shazam_kit/tree/fix-16k Unfortunately, after trying everything, my app still doesn't meet the (not so) new 16 KB native library alignment. Also, I'm 100% sure it comes from that because the error message disappears if I remove that package from my app. So after investigating, it seems that the problem comes from the ShazamKit for Android (that you can find here: https://developer.apple.com/download/all/?q=Android%20ShazamKit), and especially the .so files in the .aar file. Is there anything I can do to fix that, or should I wait before the ShazamKit team fix that? I'm totally stuck with that so any help is highly appreciated. Thanks.

[AVFCore] IOS 26.0 EXC_BAD_ACCESS from _customCompositorShouldCancelPendingFrames
Hi, I'm working an a video editing software that lets you composite and export videos. I use a custom compositor to apply my effects etc. In my crash dashboard, I am seeing a report of an EXC_BAD_ACCESS crash from objc_msgSend. Below is the stacktrace. libobjc.A.dylib objc_msgSend libdispatch.dylib _dispatch_sync_invoke_and_complete_recurse libdispatch.dylib _dispatch_sync_f_slow [symbolication failed] libdispatch.dylib _dispatch_client_callout libdispatch.dylib _dispatch_lane_barrier_sync_invoke_and_complete AVFCore -[AVCustomVideoCompositorSession(AVCustomVideoCompositorSession_FigCallbackHandling) _customCompositorShouldCancelPendingFrames] AVFCore _customCompositorShouldCancelPendingFramesCallback MediaToolbox remoteVideoCompositor_HandleVideoCompositorClientMessage CoreMedia __figXPCConnection_CallClientMessageHandlers_block_invoke libdispatch.dylib _dispatch_call_block_and_release libdispatch.dylib _dispatch_client_callout libdispatch.dylib _dispatch_lane_serial_drain libdispatch.dylib _dispatch_lane_invoke libdispatch.dylib _dispatch_root_queue_drain_deferred_wlh libdispatch.dylib _dispatch_workloop_worker_thread libsystem_pthread.dylib _pthread_wqthread libsystem_pthread.dylib start_wqthread What stood out to me is that this is only being reported from IOS 26.0+ devices. A part of the stacktrace failed to be symbolicated [symbolication failed]. I'm 90% confident that this is Apple code, not my app's code. I cannot reproduce this locally. Is this a known issue? What are the possible root-causes, and how can I verify/eliminate them? Thanks,

How to fetch a library song via MusicKit or Apple Music API if the id a non numeric format?
If I fetch a library playlist like the generated "Favorites" playlist via MusicKit like this guard let initialTracks = try await playlist.with([.tracks]).tracks else { return nil } I get a list of tracks like this: ... TrackID: i.e5gmPS6rZ856 TrackID: i.4ZQMxU0OxNg0 TrackID: i.J198KH4P85K4 TrackID: i.J1AaRC4P85K4 TrackID: i.4BPqWt0OxNg0 TrackID: 4473570282773028026 TrackID: 4473570282773028025 TrackID: 4015088256684964387 TrackID: 4473570282773028024 TrackID: 7541557725362154249 TrackID: 4473570282773028027 I save the IDs for later use, but when I want to fetch them, only the ones with ids that starts with "i." work. static func getLibrarySong(from id: String) async -> Song? { var request = MusicLibraryRequest<Song>() request.filter(matching: \.id, equalTo: MusicItemID(id)) do { let response = try await request.response() return response.items.first } catch { ... } } Or the Apple Music API endpoint : static func getLibrarySongFromAPI(with id: String) async -> Song? { guard let url = AppleMusicURL.getURL(for: .getSongById, id: id) else { return nil } do { let dataRequest = MusicDataRequest(urlRequest: URLRequest(url: url)) let dataResponse = try await dataRequest.response() let response = try JSONDecoder().decode(SongsResponse.self, from: dataResponse.data) return response.data.first } catch { ... } } Both functions above won't work for the non numeric like 4473570282773028024 so it seems the ID is wrong, but how do I make it work? Otherwise I can fetch all the songs fine, in catalog or in the library, but these few songs can't be individually fetched, only with the try await playlist.with([.tracks])` fetch, that gets the whole playlist. But obviously this isn't always possible. Thanks in advance!

Apple Music treats asian artists with romanized names as two different names
Hello, I'm trying to write a shortcut using Toolbox Pro that gets triggered by an accessibility trigger and then favorites the currently playing song. It's working pretty well, but I noticed that for some artists, especially asian ones, it simply doesn't work. While debugging, I noticed that the tool uses the same song ID, artist ID, everything as it should to search for the song and favorite it. However, I noticed that Apple Music treats artists with romanized names as two separate artists! https://music.apple.com/br/artist/王菲/41760704 https://music.apple.com/br/artist/faye-wong/41760704?l=en-GB You can see that the ID is the same (41760704). It seems that, when I search for the artist, the first artist (王菲) returns, so that when I open URLs on the web for the artist I can see a star next to the song name, meaning that it got a like. However, the romanized artist (faye-wong) doesn't have a like on the same song. This is very weird, right?

FaceTime Hang Up
When I’m on FaceTime, my phone will randomly end my call? I have an iPhone 17, iOS 26.1. Some times I won’t even be touching my phone screen and it’ll hang up. I’m not sure if this is a universal issue or just a me problem. It’s getting really annoying.

TrackID: i.e5gmPS6rZ856 TrackID: i.4ZQMxU0OxNg0 TrackID: i.J198KH4P85K4 TrackID: i.J1AaRC4P85K4 TrackID: i.4BPqWt0OxNg0 TrackID: 4473570282773028026 TrackID: 4473570282773028025 TrackID: 4015088256684964387 TrackID: 4473570282773028024 TrackID: 7541557725362154249 TrackID: 4473570282773028027 I save the IDs for later use, but when I want to fetch them, only the ones with ids that starts with "i." work. static func getLibrarySong(from id: String) async -> Song? { var request = MusicLibraryRequest<Song>() request.filter(matching: \.id, equalTo: MusicItemID(id)) do { let response = try await request.response() return response.items.first } catch { ... } } Or the Apple Music API endpoint : static func getLibrarySongFromAPI(with id: String) async -> Song? { guard let url = AppleMusicURL.getURL(for: .getSongById, id: id) else { return nil } do { let dataRequest = MusicDataRequest(urlRequest: URLRequest(url: url)) let dataResponse = try await dataRequest.response() let response = try JSONDecoder().decode(SongsResponse.self, from: dataResponse.data) return response.data.first } catch { ... } } Both functions above won't work for the non numeric like 4473570282773028024 so it seems the ID is wrong, but how do I make it work? Otherwise I can fetch all the songs fine, in catalog or in the library, but these few songs can't be individually fetched, only with the try await playlist.with([.tracks])` fetch, that gets the whole playlist. But obviously this isn't always possible. Thanks in advance!

Apple Music treats asian artists with romanized names as two different names
Hello, I'm trying to write a shortcut using Toolbox Pro that gets triggered by an accessibility trigger and then favorites the currently playing song. It's working pretty well, but I noticed that for some artists, especially asian ones, it simply doesn't work. While debugging, I noticed that the tool uses the same song ID, artist ID, everything as it should to search for the song and favorite it. However, I noticed that Apple Music treats artists with romanized names as two separate artists! https://music.apple.com/br/artist/王菲/41760704 https://music.apple.com/br/artist/faye-wong/41760704?l=en-GB You can see that the ID is the same (41760704). It seems that, when I search for the artist, the first artist (王菲) returns, so that when I open URLs on the web for the artist I can see a star next to the song name, meaning that it got a like. However, the romanized artist (faye-wong) doesn't have a like on the same song. This is very weird, right?

FaceTime Hang Up
When I’m on FaceTime, my phone will randomly end my call? I have an iPhone 17, iOS 26.1. Some times I won’t even be touching my phone screen and it’ll hang up. I’m not sure if this is a universal issue or just a me problem. It’s getting really annoying.
