Hi, In the iOS13 and macOS Catalina release notes it says: Metal CIKernel instances now support arguments with arbitrarily structured data. I've been trying to use this functionality in a CIKernel with mixed results. I'm particularly interested in passing data in the form of a dynamically sized array. It seems to work up to a certain size. Beyond the threshold excessive data is discarded and the kernel becomes unstable. I assume there is some kind of memory alignment issue going on, but I've tried various types in my array and always get a similar result. I have not found any documentation or sample code regarding this. It would be great to know how this is intended to work and what the limitations are. In the forums there are two similar unanswered questions about data arguments, so I'm sure there are a few out there with similar issues. Thanks! Michael

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)) } } }

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 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.

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,

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.

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

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!

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?

With older iOS versions, when user taps Mute/Volume button on AVPLayerViewController to unmute, the system restores the sound volume of device to the level when user muted before. On iOS 26, when user taps unmute button on screen, the volume starts from 0 (not restore). (but it still restores if user unmutes by pressing physical volume buttons). As I understand, the Volume bar/button on AVPlayerViewController is MPVolumeView, and I can not control it. So this is a feature of the system. But I got complaints that this is a bug. I did not find documents that describe this change of Mute button behavior. I need some bases to explain this situation. Thank you.

I use htttps://api.music.apple.com/v1/me/library/playlists/${playlistId}/tracks to add tracks to a playlist I created. How do I DELETE tracks from the playlist? The documentation does not mention a method for this. I have tried calling DELETE methods in various combinations but nothing seems to work. Is this possible?

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.

My app is properly configured with MusicKit. I've generated a JWT using my valid credentials (Team ID, Key ID, private key), and I’ve ensured the time settings are correct via NTP. When I call: https://api.music.apple.com/v1/catalog/jp/search?term=ado&amp;types=songs I consistently receive a 500 Internal Server Error. The JWT is generated using ES256 with valid iat and exp values. I’ve confirmed the token decodes properly using jwt.io, and it's passed via the Authorization: Bearer header. Things I’ve confirmed: Key ID, Team ID, private key are correct App ID is configured with MusicKit capability JWT is generated and signed correctly macOS time is synced via NTP Used both curl and Python to test — same result Is there anything else I should check on the Apple Developer Console (like App ID, Certificates, or provisioning profile)? Or could this be a backend issue on Apple’s side? Any guidance would be appreciated.

If I make a request to https://api.music.apple.com/v1/storefronts/us with the proper developer jwt token in the header, I receive the a successful response with a list of store fronts. If I remove the token, I do get back a 401 error. If I call any other catalog base query, I am getting back a 500 error. For instance: https://api.music.apple.com/v1/catalog/us/albums/310730204 returns a 500 error with the body being {"message":"An unexpected error occurred"} I'm not sure what I can do to fix this. Please help.

Dear Apple Developer Team, On iOS 26, the contents of PDF pages appear to be swapped. Could you please advise if there is a workaround or a planned fix for this issue? Steps to Reproduce: Download the attached PDF on iOS 26. Open the PDF in the Files app. Tap the PDF to view it in Quick Look. Navigate to page 5. Expected Result: The page number displayed at the bottom should be 5. Actual Result: The page number displayed at the bottom is 4. Issue: This is not limited to page 5—multiple page contents appear to be swapped. I have also submitted feedback via Feedback Assistant (FB20743531) on October 20. Best regards, Yoshihito Suezawa

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?

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.
