Will the restrictions on callkit be lifted in China in 2025? If so, how can you legally use callkit in China?

I use the iTunes Library framework in one of my apps, starting with macOS Sequoia 15.1 i can't create the ITLibrary object anymore with the following error: Connection to amplibraryd was interrupted. clientName:iTunesLibrary(ITLibraryLoader) Error connecting to the server via proxy object Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.amp.library.framework" UserInfo={NSDebugDescription=connection to service named com.apple.amp.library.framework} configure failed: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.amp.library.framework" UserInfo={NSDebugDescription=connection to service named com.apple.amp.library.framework} I created a new sandboxed macOS app, added the music folder read permission and it reproduced the error: import SwiftUI import iTunesLibrary @main struct ITLibraryLoaderApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { var body: some View { Button("Load ITLibrary") { loadLibrary() } } func loadLibrary() { do { let _ = try ITLibrary(apiVersion: "1.0", options: .none) } catch { print(error) } } } I restarted my developer machine and the music app with no luck.

Hi, is there a way to display the animated cover art in an app? Not every album has a cover art but for the ones that have one I would like to display them instead of the artwork. Thank you :)

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!

Hello, I'm sporadically getting the unknown CoreHaptics error described in the title, when trying to create a CHHapticPatternPlayer from an .ahap file — this does not occur in a repeatable manner, unfortunately... This occurs in a SpriteKit game, running on both iOS 17 and 18. Anyone know what the error means, since it's apparently undocumented? Note that the haptics engine is started right before creating the pattern, and the start request doesn't appear to fail... Thanks, D.

I've been working with MusicKit without enrolling for a developer account and I haven't run into any issues until I noticed nil on the SysteyMusicPlayer item for some songs and I don't understand why. Are some songs blocked from the framework? Or is it somehow a limitation to not having registered MusicKit to the bundle ID? I am planning on using MusicKit properly in prod and this is just a test app for a package I'm working on. These are the nil songs which I got from the Discovery Station: https://music.apple.com/ca/album/okay/950816298?i=950816304 https://music.apple.com/ca/album/youre-so-cool/1670485433?i=1670485446

I'm building a camera app that does some post processing after the photo has been taken. With 12MP the processing is pretty good, but larger images 24MP is very slow. I created a very simple example to demonstrate the issue, which is loading an image and the rendering it to data. let context = CIContext() let imageUrl = Bundle.main.url(forResource: "12mp", withExtension: "jpg")! let data = try! Data(contentsOf: imageUrl) let ciImage = CIImage(data: data)! let start = CFAbsoluteTimeGetCurrent() let data = context.jpegRepresentation(of: ciImage, colorSpace: context.workingColorSpace!) print(data?.count) print("Resize Completed: " + String(CFAbsoluteTimeGetCurrent() - start)) Running this code on an iPhone 16 Pro with different images produces these benchmarks: 12MP => 0.03s 24MP => 1.22s 48MP => 2.98s I understand that processing time will increase with resolution but it doesn't seem linear. I have tried setting different CiContext options such as .useSoftwareRenderer: false but it has made no difference. From profiling the process it looks like the JPEG decoding is the bottle neck. This is for a 48MP Image: Is there any way this can be improved?

Hi, I am trying to enable the default MIDINetworkSession in a Catalyst app on MacOS like this: MIDINetworkSession.default().isEnabled = true MIDINetworkSession.default().connectionPolicy = .anyone In the AppSandbox I have both incoming and outgoing network connections enabled. And I also added the NSLocalNetworkUsageDescription key to the info.plist. Bonjour services are also added to the info.plist: NSBonjourServices _apple-midi._udp. Nevertheless the session stays disabled. Running the same code works just fine on iOS. Is there any special setup I need to make on MacOS to enable the MIDINetworkSession? Thanks!

I am building an app for MacOS and I am trying to implement the code to add songs to a library playlist (which is added below). The issue I am having is that if I use Music Kit to load a users library playlists, the ID for the playlist (which is just a string of numbers) does not work with the Add tracks to a Library Playlist endpoint of Apple Music API. If I retrieve the playlists from the Apple Music API and use that playlist ID (which is different than the id I get from MusicKit) my code works fine and adds the song to the playlist. The problem is that when getting a users library playlists from Apple Music API is that it does not give me all of the library playlists that I get when using Music Kit and it also does not give me Artwork for playlists that have the collage of album covers, so I would prefer to use Music Kit to get the playlists. I have also tested trying to retrieve a single playlist using the Apple Music API with the playlist Id from Music Kit and it does not work. I get the error that the resource cannot be found. Since this is a macOs app I cannot use MusicKit to add songs to library playlists. Does anyone know a way to resolve this? Or a possible workaround? Ideally I want to use MusicKit to get the library playlists and have some way to use the playlist Id and add songs to that playlist. Below is my code for adding a song to a playlist using the Apple Music API, which works correctly only if I originally get the library playlist's id value from a playlist retrieved from the Apple Music API. Also, does anyone know why the playlist Id's are not universal and are different when using Music Kit and Apple Music API? For songs and tracks it does not seem to matter if I use music kit or Apple Music API, the Id's are in the correct format for Apple Music API to use and work with my code. Thanks everyone for any and all help! func addToPlaylist(songs: [Track], playlist: Playlist, alert: Binding<AlertItem?>) async { let tracks = AppleMusicPlaylistPostRequestBody(data: songs.compactMap { AppleMusicPlaylistPostRequestItem(id: $0.id.rawValue, type: "songs") // or "library-songs" }) let playlistID = playlist.id // Build the request URL for adding a song to a playlist guard let url = URL(string: "https://api.music.apple.com/v1/me/library/playlists/\(playlistID)/tracks") else { alert.wrappedValue = AlertItem(title: "Error", message: "Invalid URL for the playlist.") return } // Authorization Header guard let musicUserToken = try? await MusicUserTokenProvider().getUserMusicToken() else { alert.wrappedValue = AlertItem(title: "Error", message: "Unable to retrieve Music User Token.") return } do { var request = URLRequest(url: url) request.httpMethod = "POST" request.setValue("Bearer \(musicUserToken)", forHTTPHeaderField: "Authorization") request.setValue("application/json", forHTTPHeaderField: "Content-Type") let encoder = JSONEncoder() let data = try encoder.encode(tracks) request.httpBody = data let musicRequest = MusicDataRequest(urlRequest: request) let musicRequestResponse = try await musicRequest.response() // Check if the request was successful (status 201) if musicRequestResponse.urlResponse.statusCode == 201 { alert.wrappedValue = AlertItem(title: "Success", message: "Song successfully added to the playlist.") } else { print("Status Code: \(musicRequestResponse.urlResponse.statusCode)") print("Response Data: \(String(data: musicRequestResponse.data, encoding: .utf8) ??

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

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!

My iphone 15 plus suddenly turns black and a losing icon keeps spinning. Then it turns off and I can use it again, it is only for a few seconds. I have updated to iOS 18.1 beta, could this be the issue. Is my phone broken? I have tried restarting my phone

Hi, I'm wondering about one of the properties in the MPNowPlayingInfoCenter: MPNowPlayingInfoPropertyElapsedPlaybackTime. The docs say that updating this property frequently is not required, because the system can automatically calculate elapsed playback time based on the infrequent values we provide. Is performance harmed by updating this property every second? Should I add some filtering/throttling to update this property infrequently? Am I overthinking this, and it doesn't matter either way? Kind regards.

Hi - Of course I may be doing something wrong, but I'm getting exactly the opposite of what I would expect from ApplicationMusicPlayer.shared.state.playbackStatus It returns .playing when the music is paused and .paused when the music is playing. Am I holding it wrong? Thanks, Daniel

I have a custom app running on a Mac Studio with Ventura that grabs a snapshot image from a network camera. It then adds some extra information into the EXIF "MakerNote" field. However the metadata cannot be read back out of the image when running Ventrua, it can however be read out of the same image file on a Mac that is not running Ventura. It would appear Apple has removed support for reading MakerNote in Ventura but still supports writing MakerNote in Ventura. This code is about 7 years old and written in ObjC and has worked with no issue until Ventura came along. Calls used CGImageDestinationAddImageFromSource(); // used to write the image to disk with the extra metadata - Works on Ventura CGImageSourceCopyPropertiesAtIndex(); // used to read the meta data from an image - does not return "MakeNote" data Is there a new way to read EXIF "MakeNote" data from image files that was introduced with Ventura?

Hey there, I'm trying to display all user's albums using the MediaPlayer library. I'm getting many albums returning nil, but I know artwork exists because they show up in the default Music app. There doesn't seem to be much rhyme or reason for what shows up and what doesn't. All downloaded albums display artwork, but some cloud album artwork displays as well. Here's the code I'm using to debug this. let query = MPMediaQuery.albums() if let albumCollections = query.collections { albums = albumCollections } for album in albums { let artwork = album.representativeItem?.artwork print(artwork, artwork?.image(at: CGSize(width: 100, height: 100))) } Any help would be greatly appreciated. Thanks!

We develop a video playback app on Apple TV which has the two following features: Its content browsing screen has installed a gesture recognizer for presses on the PlayPause Siri remote button in order to directly launch a playback. The gesture recognizer is attached to the content browsing UIViewController view. It presents its own custom playback UI with an AVPlayerLayer for the video and supports MPNowPlayingSession in order to publish current playback information and respond to remote commands. It also supports switching between fullscreen and Picture in Picture playback. Both features work fine, ie. the playback is launched when pressing the PlayPause Siri remote button and, during playback, the playback info are properly advertised on other devices and remote commands are also triggered as expected. However, when pressing the PlayPause Siri remote button while the video is playing in PiP, the "pause" remote command is sometimes triggered instead of the .playPause gesture recognizer. The issue may not occur the first time but for subsequent PlayPause presses. Navigating a bit in the app UI seems to help preventing the issue to occur. Finally, the issue only occurs if the video is playing. If the video is paused, the PlayPause Siri remote button gesture is always recognized instead of the remote command. Please note that, before using MPNowPlayingSession (and the corresponding MPRemoteCommandCenter), the app was using the default MPRemoteCommandCenter to support remote commands and the issue did not occur. We don't reproduce this issue with the Apple TV app so there's probably something we are not doing right. Has someone any clue?

My app reports a lot of crashes from 18.2 users. I have been able to narrow down the issue to this line of code: CGImageDestinationFinalize(imageDestination) The error is Thread 93: EXC_BAD_ACCESS (code=1, address=0x146318000) But I have no idea why this suddently started to crash. Here is the code of the function: private func estimateSizeUsingThumbnailMethod(fromImageURL url: URL, imageSettings: ImageSettings) -> (Int, Int) { let sourceOptions = [kCGImageSourceShouldCache: false] as CFDictionary guard let source = CGImageSourceCreateWithURL(url as CFURL, sourceOptions), let imageProperties = CGImageSourceCopyPropertiesAtIndex(source, 0, nil) as? [CFString: Any], let imageWidth = imageProperties[kCGImagePropertyPixelWidth] as? CGFloat, let imageHeight = imageProperties[kCGImagePropertyPixelHeight] as? CGFloat else { return (0, 0) } let maxImageSize = max(imageWidth, imageHeight) let thumbMaxSize = min(2400, maxImageSize) // Use original size if possible, but not if larger than 2400, in this case we'll extrapolate from thumbnail let downsampleOptions = [ kCGImageSourceCreateThumbnailFromImageAlways: true, kCGImageSourceCreateThumbnailWithTransform: true, kCGImageSourceThumbnailMaxPixelSize: thumbMaxSize as CFNumber, ] as CFDictionary guard let cgImage = CGImageSourceCreateThumbnailAtIndex(source, 0, downsampleOptions) else { DLog("CGImage thumb creation error") return (0, 0) } let data = NSMutableData() guard let imageDestination = CGImageDestinationCreateWithData(data, UTType.jpeg.identifier as CFString, 1, nil) else { DLog("CGImage destination creation error") return (0, 0) } let destinationProperties = [ kCGImageDestinationLossyCompressionQuality: imageSettings.quality.compressionRatio() // Set jpeg compression ratio ] as CFDictionary CGImageDestinationAddImage(imageDestination, cgImage, destinationProperties) CGImageDestinationFinalize(imageDestination) // <----- CRASHES HERE with EXC_BAD_ACCESS ... } So far, I'm stuck. Any idea that could help would be greatly appreciated, as I'm scared that this crash will propagate on the official release of 18.2
