add a currently playing track endpoint on the apple music api. its kinda wild how apple music goes after spotify without having such a useful endpoint.

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,

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!

Fetching the featured artists in a playlist, no longer works in iOS 26.1 beta let detailedPlaylist = try await playlist.with([.tracks, .featuredArtists], preferredSource: .library) Throws error when using .library and using .catalog returns empty array. This works correctly in iOS 26.0 and iOS 18 versions

Hi there, I recently launched a dj app to the mac app store, and was wondering how I could access raw data to songs from apple music just like how serato, rekordbox, djay, etc. do? Thanks, Gunek

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?

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.

Hey Swift community! I'm exploring building a macOS app that needs to monitor what's currently playing in music apps like Spotify and Apple Music (track info, playback position, play/pause state). I'm trying to figure out the most efficient architecture before diving in. The Goal: Monitor playback state across multiple music players to react to changes in real-time, ideally with minimal CPU overhead since this would run continuously in the background. Approaches I'm Considering AppleScript / ScriptingBridge Distributed Notifications Native Frameworks (Apple Music only) What's the recommended way to do this on macOS? Are distributed notifications reliable enough to avoid polling entirely? Is there a performance difference between AppleScript and ScriptingBridge for IPC? For Apple Music specifically, should I use MusicKit, MediaPlayer, or stick with AppleScript? Are there other approaches I'm missing?

Hello, We are experiencing on some occasions a wrong behavior with PDFDocument method: func page(at index: Int) -> PDFPage? With certain PDF files, this method returns the wrong PDFPage. This occurs on iOS 18.3, 18.5 and 18.6.2 (an maybe on other versions). Try this PDF for instance (page 81 is returned when index = 2): https://drive.google.com/open?id=1MHm2wjfsbWB8OiRmARUMmvODYxp4DIqP&usp=drive_fs Also, I mention that this doesn't occur systematically with this PDF. When making a copy of this file we don't observe the issue. Could this be linked some kind of internal cache issue ?

Hi, We identified massive amounts of leaked memory with the tvOS 26 standard player user interface as soon as chapters (navigation markers) are involved. Artwork images associated with chapters are not correctly released anymore, leaking memory in chunks of several MiBs. Over time apps will be terminated by the system due to excessive memory consumption. The issue was reported to Apple as tvOS 26 regression: Huge memory leaks associated with navigation marker artworks displayed in the tvOS standard user interface, filed under FB21160665.

Hi all, I've been working on some personal programming projects and have gotten into using the Apple Music API. I'm currently looking to get a list of recent songs using the /v1/me/recent/played/tracks endpoint and it's working well. However, I know there are some songs I've listened to multiple times in a row, and those are not showing up as unique tracks when querying this endpoint. I'm only seeing a list of the different songs I've listened to lately, not a true list of the most recent plays on my account. Is this intended behavior or am I going about something incorrectly here? My query is using that endpoint & specifying the types to be only [songs]. Thanks in advance for any ideas or insight.

Has anyone seen this issue? We have a user who changed their Apple ID password about 5 days ago. Now when they authenticate via MusicKit JS: authorize() succeeds and returns a user token Immediately calling any /me/ endpoint returns 403 "Invalid authentication" (code 40300) Developer token works fine on catalog endpoints User has active Apple Music subscription Other users work fine through the same flow App doesn't appear in user's "Apps Using Your Apple ID" We've tried: Calling unauthorize() before authorize() Clearing localStorage/sessionStorage/cookies Multiple re-auth attempts over several days The token is freshly issued but Apple's API immediately rejects it. Anyone encountered this after a password change? Any workarounds?

I’m trying to build a playlist editor on macOS. I can create playlists via the Apple Music HTTP API, but DELETE always returns 401 even immediately after creation with the same tokens. Minimal repro: #!/usr/bin/env bash set -euo pipefail BASE_URL="https://api.music.apple.com/v1" PLAYLIST_NAME="${PLAYLIST_NAME:-blah}" : "${APPLE_MUSIC_DEV_TOKEN:?}" : "${APPLE_MUSIC_USER_TOKEN:?}" create_body="$(mktemp)" delete_body="$(mktemp)" trap 'rm -f "$create_body" "$delete_body"' EXIT curl -sS --compressed -o "$create_body" -w "Create status: %{http_code}\n" \ -X POST "${BASE_URL}/me/library/playlists" \ -H "Authorization: Bearer ${APPLE_MUSIC_DEV_TOKEN}" \ -H "Music-User-Token: ${APPLE_MUSIC_USER_TOKEN}" \ -H "Content-Type: application/json" \ -d "{\"attributes\":{\"name\":\"${PLAYLIST_NAME}\"}}" playlist_id="$(python3 - "$create_body" <<'PY' import json, sys with open(sys.argv[1], "r", encoding="utf-8") as f: data = json.load(f) print(data["data"][0]["id"]) PY )" curl -sS --compressed -o "$delete_body" -w "Delete status: %{http_code}\n" \ -X DELETE "${BASE_URL}/me/library/playlists/${playlist_id}" \ -H "Authorization: Bearer ${APPLE_MUSIC_DEV_TOKEN}" \ -H "Music-User-Token: ${APPLE_MUSIC_USER_TOKEN}" \ -H "Content-Type: application/json" I capture the response bodies like this: cat "$create_body" cat "$delete_body" Result: Create: 201 Delete: 401 I also checked the latest macOS SDK’s MusicKit interfaces and MusicLibrary.createPlaylist/edit/add(to:) are marked @available(macOS, unavailable), so I can’t create/ delete via MusicKit on macOS either. Question: How can I implement a playlist editor on macOS (create/delete/modify) if: MusicKit write APIs are unavailable on macOS, and The HTTP API can create but DELETE returns 401? Any guidance or official workaround would be hugely appreciated.

I’ve been struggling with a very frustrating issue using the new iOS 26 Swift Concurrency APIs for video processing. My pipeline reads frames using AVAssetReader, processes them via CIContext (Lanczos upscale), and then appends the result to an AVAssetWriter using the new PixelBufferReceiver. The Problem: The execution randomly stops at the ]await append(...)] call. The task suspends and never resumes. It is completely unpredictable: It might hang on the very first run, or it might work fine for 4-5 runs and then hang on the next one. It is independent of video duration: It happens with 5-second clips just as often as with long videos. No feedback from the system: There is no crash, no error thrown, and CPU usage drops to zero. The thread just stays in the suspended state indefinitely. If I manually cancel the operation and restart the VideoEngine, it usually starts working again for a few more attempts, which makes me suspect some internal resource exhaustion or a deadlock between the GPU context and the writer's input. The Code: Here is a simplified version of my processing loop: private func proccessVideoPipeline( readerOutputProvider: AVAssetReaderOutput.Provider<CMReadySampleBuffer<CMSampleBuffer.DynamicContent>>, pixelBufferReceiver: AVAssetWriterInput.PixelBufferReceiver, nominalFrameRate: Float, targetSize: CGSize ) async throws { while !Task.isCancelled, let payload = try await readerOutputProvider.next() { let sampleBufferInfo: (imageBuffer: CVPixelBuffer?, presentationTimeStamp: CMTime) = payload.withUnsafeSampleBuffer { sampleBuffer in return (sampleBuffer.imageBuffer, sampleBuffer.presentationTimeStamp) } guard let currentPixelBuffer = sampleBufferInfo.imageBuffer else { throw AsyncFrameProcessorError.missingImageBuffer } guard let pixelBufferPool = pixelBufferReceiver.pixelBufferPool else { throw NSError(domain: "PixelBufferPool", code: -1, userInfo: [NSLocalizedDescriptionKey: "No pixel buffer pool available"]) } let newPixelBuffer = try pixelBufferPool.makeMutablePixelBuffer() let newCVPixelBuffer = newPixelBuffer.withUnsafeBuffer({ $0 }) try upscale(currentPixelBuffer, outputPixelBuffer: newCVPixelBuffer, targetSize: targetSize ) let presentationTime = sampleBufferInfo.presentationTimeStamp try await pixelBufferReceiver.append(.init(unsafeBuffer: newCVPixelBuffer), with: presentationTime) } } Does anyone know how to fix it?

When I use the ColorSync Utility to convert Display P3 color (1, 0, 0) to an XYZ color, the result is (0.5151, 0.2412, -0.0011). I expected that result because that is identical to the red colorant tristimulus value in the Display P3.icc file.When I use the CGColor converted method to do the same, the XYZ color is approximately (0.5151, 0.2412, 0.0). Note that the third element is 0.0 whereas it is -0.0011 when using the ColorSync Utility. I have printed out the Z component to 16 digits of precision, and Z is all 0s. It appears that the CGColor converted method is clamping the result from 0 to 1.My questions are:1. Which conversion is correct? The ColorSync utility or the CGColor converted method?2. I am not a color specialist, but I thought that the XYZ components should never be negative. If so, is the colorant tristimulus value in the Display P3.icc file wrong?3. Because CGColor clamped the Z component to 0, the XYZ color cannot be converted back exactly or closely to the Display P3 color (1, 0, 0). I would have expected to be able to go back and forth between the two color spaces when starting from a valid P3 Display color especially since the XYZ color space completely encompasses the P3 Display color space. Is that not true?4. Is (1, 0, 0) an invalid Display P3 color? If so, I can understand the peculiar results. I'm not sure how I would know if a Display P3 color is valid or not. (I only know that the component values must be from 0 to 1.) I think it is valid because Apple uses that color in the UIColor API Reference in an example.

Hello, I am wondering how one can play music videos (with the actual video playing) with the ApplicationMusicPlayer using MusicKit for Swift? There is not much documentation on this, so any help would be appreciated.

I've just begun to dip my toes into the iOS16 waters. One of the first things that I've attempted is to edit a library playlist using: try await MusicLibrary.shared.edit(targetPlaylist, items: tracksToAdd) Where targetPlaylist is of type MusicItemCollection<MusicKit.Playlist>.Element and tracksToAdd is of type [Track] The targetPlaylist was created, using new iOS16 way, here: let newPlaylist = try await MusicLibrary.shared.createPlaylist(name: name, description: description) tracksToAdd is derived by performing a MusicLibraryRequest on a specific playlist ID, and then doing something like this: if let tracksToAdd = try await playlist.with(.tracks).tracks {    // add tracks to target playlist } My problem is that when I perform attempt the edit, I am faced with a rather sad looking crash. libdispatch.dylib`dispatch_group_leave.cold.1:     0x10b43d62c <+0>:  mov    x8, #0x0     0x10b43d630 <+4>:  stp    x20, x21, [sp, #-0x10]!     0x10b43d634 <+8>:  adrp   x20, 6     0x10b43d638 <+12>: add    x20, x20, #0xfbf          ; "BUG IN CLIENT OF LIBDISPATCH: Unbalanced call to dispatch_group_leave()"     0x10b43d63c <+16>: adrp   x21, 40     0x10b43d640 <+20>: add    x21, x21, #0x260          ; gCRAnnotations     0x10b43d644 <+24>: str    x20, [x21, #0x8]     0x10b43d648 <+28>: str    x8, [x21, #0x38]     0x10b43d64c <+32>: ldp    x20, x21, [sp], #0x10 ->  0x10b43d650 <+36>: brk    #0x1 I assume that I must be doing something wrong, but I frankly have no idea how to troubleshoot this.

I've been using CGWindowListCreateImage which automatically creates an image with the size of the captured window. But SCScreenshotManager.captureImage(contentFilter:configuration:) always creates images with the width and height specified in the provided SCStreamConfiguration. I could be setting the size explicitly by reading SCWindow.frame or SCContentFilter.contentRect and multiplying the width and height by SCContentFilter.pointPixelScale , but it won't work if I want to keep the window shadow with SCStreamConfiguration.ignoreShadowsSingleWindow = false. Is there a way and what's the best way to take full-resolution screenshots of the correct size? import Cocoa import ScreenCaptureKit class ViewController: NSViewController { @IBOutlet weak var imageView: NSImageView! override func viewDidAppear() { imageView.imageScaling = .scaleProportionallyUpOrDown view.wantsLayer = true view.layer!.backgroundColor = .init(red: 1, green: 0, blue: 0, alpha: 1) Task { let windows = try await SCShareableContent.excludingDesktopWindows(false, onScreenWindowsOnly: true).windows let window = windows[0] let filter = SCContentFilter(desktopIndependentWindow: window) let configuration = SCStreamConfiguration() configuration.ignoreShadowsSingleWindow = false configuration.showsCursor = false configuration.width = Int(Float(filter.contentRect.width) * filter.pointPixelScale) configuration.height = Int(Float(filter.contentRect.height) * filter.pointPixelScale) print(filter.contentRect) let windowImage = try await SCScreenshotManager.captureImage(contentFilter: filter, configuration: configuration) imageView.image = NSImage(cgImage: windowImage, size: CGSize(width: windowImage.width, height: windowImage.height)) } } }

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).
