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,  em

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"

I'm playing library items (MPMediaItem) and apple music tracks (Track) in MPMusicPlayerApplicationController.applicationQueuePlayer, but I can't use the actual Queue functionality because I can't figure out how to get both media types into the same queue. If there's a way to get both types in a single queue, that would solve my problem, but I've given up on that one. Because I can't use a queue, I have to be able to detect when a song ends so that I can put the next song in the queue and play it. The only way I can figure out to detect when a song ends is by watching the playBackState, and I've actually got that pretty much working, but it's really ugly, because you get playBackState of paused when a song ends, and when a bluetooth speaker disconnects, etc. The only answer I've been able to find on the internet is to watch the MPMusicPlayerControllerNowPlayingItemDidChange, and when that fires, and the nowPlayingItem is NIL, a song ends.. but that's not the case. When a song ends, the nowPlayingItem remains the same. There's got to be an answer to this problem, right?

I'm very excited about the new MusicLibrary API, but after a couple of days of playing around with it, I have to say that I find the implementation of filtering MusicLibraryRequests a little confusing. MPMediaQuery has a fairly extensive list of predicates that can be applied, including string and persistentID comparisons for artist, album artist genre, and more. It also lets you filter on an item’s title. MusicLibraryRequests let you filter on the item’s ID, or on its MusicKit Artist and Genre relationships. To me, this seems like it adds an extra step.  With an MPMediaQuery, if I wanted to fetch every album by a given artist, I’d apply an MPMediaPropertyPredicate looking at MPMediaItemPropertyAlbumArtist and compare the string. It was also easy to change the MPMediaPredicateComparison to .contains to match more widely. If I wanted to surface albums by “Aesop Rock” or “Aesop Rock & Blockhead,” I could use that. In the MusicLibraryRequest implementation, it looks like I need to perform a MusicLibraryRequest<Artist> first in order to get the Artist objects. There’s no filter for the name property, so if I don’t have their IDs, I’ve got to use filter(text:). From there, I can take the results of that request and apply them to my MusicLibraryRequest<Album> using the filter(matching:memberOf) function.  I could use filter(text:) on the MusicLibraryRequest<Album>, but that filters across multiple properties (title and artistName?) and is less precise than defining the actual property I want to match against. I think my ideal version of the MusicLibraryRequest API would offer something like filter(matching:equalTo:) or filter(matching:contains:) that worked off of KeyPaths rather than relationships. That seems more intuitive to me. I’m not saying we need every property from every filterable MPMediaItemProperty key, but I’d love to be able to do it on title, artistName, and other common metadata. That might look something like: filter(matching: \.title, contains: “Abbey Road”) filter(matching: \.artistName, equalTo: “Between The Buried And Me”) I noticed that filter(text:) is case insensitive, which is awesome, and something I’ve wanted for a long time in MPMediaPropertyPredicate. As a bonus, it would be great if a KeyPath based filter API supported a case sensitivity flag. This is less of a problem when dealing with Apple Music catalog content, but users’ libraries are a harsh environment, and you might have an artist “Between The Buried And Me” and one called “Between the Buried and Me.” It would be great to get albums from both with something like: filter(matching: \.artistName, equalTo: “Between The Buried And Me”, caseSensitive: false)  I've submitted the above as FB10185685. I also submitted another feedback this morning regarding filter(text:) and repeating text as FB10184823. My last wishlist item for this API (for the time being!) is exposing the MPMediaItemPropertyAlbumPersistentID as an available filter attribute. I know, I know… hear me out. If you take a look at the other thread I made today, you’ll see that due to missing metadata in MusicKit, I still have some use cases where I need to be able to reference an MPMediaItem and might need to fetch its containing MPMediaItemCollection to get at other tracks on the album. It would be nice to seamlessly be able to fetch the MPMediaItemCollection or the library Album using a shared identifier, especially when it comes to being able to play the album in MusicKit’s player rather than Media Player’s.  I've submitted that list bit as FB10185789 Thanks for bearing with my walls of text today. Keep up the great work!

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.

Hello, I am having difficulties with configuring MusicKit correctly for my web app that I am building, seeking assistance with the issues I am having. Would greatly appreciate any help! After allowing access to the following, "Access Request media.mydomain.com would like to access Apple Music, media library, and listening activity for myemail'@icloud.com.", I get a popup error that states, "Authorization failed. Please try again.". Following is the information that is given in developer console: [Error] Failed to load resource: the server responded with a status of 403 () (webPlayerLogout, line 0) [Error] Authorization failed: AUTHORIZATION_ERROR: Unauthorized (anonymous function) (media.mydomain.com:398)

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).

Hello! I am having trouble setting start times for songs when using the ApplicationMusicPlayer. When I initialize a new MusicPlayer.Queue.Entry using the following constructor, I am seeing strange results: init( _ playableMusicItem: PlayableMusicItem, startTime: TimeInterval? = nil, endTime: TimeInterval? = nil ) It appears that any value I provide for startTime is also applied to the endTime. For example: MusicPlayer.Queue.Entry(playable, startTime: TimeInterval(30), endTime: TimeInterval(183)) provides the following console output: MusicPlayer.Queue.Entry(id: "3D6A3DA3-595E-4657-8DBA-DDD245BBB7EF", transientItem: PlayableMusicItem, startTime: 30.0, endTime: 30.0) I have also tried setting the endTime to nil with the same result. Does anyone have any experience setting start times for songs using the MusicKit ApplicationMusicPlayer? Any feedback is greatly appreciated!

I'm creating app that listening other app's sound. in this use case, screen data is not needed. but if I don't call SCStream#addStreamOutput(_, type: .screen, ...), console shows this error: [ERROR] _SCStream_RemoteVideoQueueOperationHandlerWithError:701 stream output NOT found. Dropping frame currently I'm setting SCStreamConfiguration#minimumFrameInterval to large value (e.g. 0.1fps) as workaround, but it would be good if i can completely disable screen capture for best performance. there is any way to disable screen capture and only captures apps audio?

I'm building a UIKit app that reads user's Apple Music library and displays it. In MusicKit there is the Artwork structure which I need to use to display artwork images in the app. Since I'm not using SwiftUI I cannot use the ArtworkImage view that is recommended way of displaying those images but the Artwork structure has a method that returns url for the image which can be used to read the image. The way I have it setup is really simple: extension MusicKit.Song { func imageURL(for cgSize: CGSize) -> URL? { return artwork?.url( width: Int(cgSize.width), height: Int(cgSize.height) ) } func localImage(for cgSize: CGSize) -> UIImage? { guard let url = imageURL(for: cgSize), url.scheme == "musicKit", let data = try? Data(contentsOf: url) else { return nil } return .init(data: data) } } Now, everytime I access .artwork property (so a lot of times) the main thread gets blocked and the console output gets bombared with messages like these: 2023-07-26 11:49:47.317195+0200 Plum[998:297199] [Artwork] Failed to create color analysis for artwork: <MPMediaLibraryArtwork: 0x289591590> with error; Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.mediaartworkd.xpc was invalidated: failed at lookup with error 159 - Sandbox restriction."

I am not planning to use it anywhere and if so it should be a computed async property so it doesn't block the caller. I know I can move the call to a background thread and that fixes the issue of blocking main thread but still the loading times for each artwork are terribly slow and that impacts the UX. SwiftUI's ArtworkImage loads the artworks much quicker and without the errors so there must be a better way to do it.

I'm experiencing an issue with QuickLook in iOS 18 where.reality files with audio playback are affected. When I open a.reality file that includes audio, the audio track plays twice: once from the moment the file is opened, and again from the start of the animation. This results in a duplicate audio playback. I've tested this issue on multiple devices running iOS 16, 17, and 18, and the problem only occurs on iOS 18. I've tried restarting the devices and checking for any software updates, but the issue persists. Steps to reproduce: Open a.reality file with audio playback in QuickLook on an iOS 18 device. Observe the audio playback. Expected result: The audio track should play only once, from the start of the animation. Actual result: The audio track plays twice, once from the moment the file is opened and again from the start of the animation. Device and iOS version: I've tested this issue on iPhone 12 Pro, iPhone 13 Pro running iOS 18, iPhone 13 running iOS 16 and iPhone 11 Pro running iOS 17,

I'm unable to play music using Musickit.js in the Chrome or Firefox browsers. Even using the apple guide here: https://js-cdn.music.apple.com/musickit/v1/index.html - I've added my Music Developer Token and song/album url, but it only works in Safari and not in Chrome or Firefox. I'm unsure if this is a global issue, or if there is something I need to do to enable playback in other browsers, but as it stands it's not working for me. Thanks for any help in advance!

I've been having issues with authorization after switching from v1 to v3, have tried some of the suggestions provided by someone in a reply to a post of mine. Have tried to reach out to Apple Support a few times as well, though I haven't received any support that has helped me to move forward. I have tested my token at https://jwt.io and I'm getting a "Signature Verified", tried multiple browsers in private/incognito mode, now when I try to sign into my Apple Account to test my player I am receiving an error that stats "There is a Problem Connecting. There May be an Issue with Your Network." (which is not the case). I have tried everything I can think of, I'm at a loss and would appreciate any help to get my project moving forward. This is what I am seeing in the browser developer console (using Firefox): Authorization failed: AUTHORIZATION_ERROR: Unauthorized MKError https://js-cdn.music.apple.com/musickit/v3/musickit.js:13 authorize https://js-cdn.music.apple.com/musickit/v3/musickit.js:28 asyncGeneratorStep$w https://js-cdn.music.apple.com/musickit/v3/musickit.js:28 _next https://js-cdn.music.apple.com/musickit/v3/musickit.js:28 media.mydomain.com:398:19 https://media.mydomain.com/:398

Hello, I noticed that SFSpeechRecognizer is broken on iOS 18. During a recognition task, it keeps dropping the recognized text on every pause. For example, if you say "how are you fine", it will drop the "how are you" part and only give you "fine" as the result. Say "how are you <pause> fine" // iOS 17 ✅ (perfect final result) How How are How are you How are you. How are you. Fine. // iOS 18 ❌ How How are How are you How are you Fine (the text before the pause is dropped, and fail to recognize the punctuations.) Reproducing the issue: Download the official sample project. Run it on an iOS 18 device or simulator. Say "how are you fine" Only "fine" will be displayed.

Since updating to iOS 18.1 my WhatsApp no longer allows reply in my car and will only read one message at a time…

Hello, Basically, I am reading and writing an asset. To simplify, I am just reading the asset and rewriting it into an output video without any modifications. However, I want to add a fade-out effect to the last three seconds of the output video. I don’t know how to do this. So far, before adding the CMSampleBuffer to the output video, I tried reducing its volume using an extension on CMSampleBuffer. In the extension, I passed 0.4 for testing, aiming to reduce the video's overall volume by 60%. My question is: How can I directly adjust the volume of a CMSampleBuffer? Here is the extension: extension CMSampleBuffer { func adjustVolume(by factor: Float) -> CMSampleBuffer? { guard let blockBuffer = CMSampleBufferGetDataBuffer(self) else { return nil } var length = 0 var dataPointer: UnsafeMutablePointer<Int8>? guard CMBlockBufferGetDataPointer(blockBuffer, atOffset: 0, lengthAtOffsetOut: nil, totalLengthOut: &length, dataPointerOut: &dataPointer) == kCMBlockBufferNoErr else { return nil } guard let dataPointer = dataPointer else { return nil } let sampleCount = length / MemoryLayout<Int16>.size dataPointer.withMemoryRebound(to: Int16.self, capacity: sampleCount) { pointer in for i in 0..<sampleCount { let sample = Float(pointer[i]) pointer[i] = Int16(sample * factor) } } return self } }

When building an application that can be built on iOS using macCatalyst, a link error like the one below will occur. Undefined symbol: OBJC_CLASS$_AVPlayerViewController The AVPlayerViewController documentation seems to support macCatalyst, but what is the reality? [AVPlayerViewController](https://developer.apple.com/documentation/avkit/avplayerviewcontroller? language=objc) Each version of the environment is as follows. Xcode 16.2 macOS deployment target: macOS 10.15 iOS deployment target: iOS 13.0 Thank you for your support.

It's simple to reproduce. The bug is simply when you queue a bunch of songs to play, it will always queue less than what you gave it. Here, I'm attempting to play an apple curated playlist, it will only queue a subset, usually less than 15, but as low as 1 out of 100. Use the system's forward and backwards to test it out. Here is the code, just paste it in to the ContentView file and make sure you have the capibility to run it. import SwiftUI import MusicKit struct ContentView: View { var body: some View { VStack{ Button("Play Music") { Task{ await playMusic() } } } } } func getOnlySongsFromTracks(tracks:MusicItemCollection<Track>?) async throws ->MusicItemCollection<Song>?{ var songs:[Song]? if let t = tracks{ songs = [Song]() for track in t { if case let .song(song) = track { songs?.append(song) print("track is song \(track.debugDescription)") }else{ print("track not song \(track.debugDescription)") } } } if let songs = songs { let topSongs = MusicItemCollection(songs) return topSongs } return nil } func playMusic() async { // Request authorization let status = await MusicAuthorization.request() guard status == .authorized else { print("Music authorization denied.") return } do { // Perform a hardcoded search for a playlist let searchTerm = "2000" let request = MusicCatalogSearchRequest(term: searchTerm, types: [Playlist.self]) let response = try await request.response() guard let playlist = response.playlists.first else { print("No playlists found for the search term '\(searchTerm)'.") return } // Fetch the songs in the playlist let detailedPlaylist = try await playlist.with([.tracks]) guard let songCollection = try await getOnlySongsFromTracks(tracks: detailedPlaylist.tracks) else { print("no songs found") return } guard let t = detailedPlaylist.tracks else { print("no tracks") return } // Create a queue and play let musicPlayer = ApplicationMusicPlayer.shared let q = ApplicationMusicPlayer.Queue(for: t) musicPlayer.queue = q try await musicPlayer.play() print("Now playing playlist: \(playlist.name)") } catch { print("An error occurred: \(error.localizedDescription)") } }

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)) } } }
