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

Add RPSystemBroadcastPickerView to the app, After clicking, no method of SampleHandler is triggered

I am calling AVSampleBufferDisplayLayer.flush from a background queue but this seems to occasionally crash the app. I am calling it from the same thread I pass to - (void)requestMediaDataWhenReadyOnQueue:(dispatch_queue_t)queue usingBlock:(void (^)(void))block;. My question is, is this API threadsafe, or do I need to call flush from the main thread? Or is there another issue that I am not considering? It seems strange to me that this API would trigger an autolayout pass. 0 CoreFoundation 0x00000001bb384e38 __exceptionPreprocess + 164 1 libobjc.A.dylib 0x00000001b451b8d8 objc_exception_throw + 59 2 CoreAutoLayout 0x00000001d7e09e84 _AssertAutoLayoutOnAllowedThreadsOnly + 327 3 CoreAutoLayout 0x00000001d7e00e60 -[NSISEngine withBehaviors:performModifications:] + 35 4 UIKitCore 0x00000001be58fd40 -[UIView _postMovedFromSuperview:] + 671 5 UIKitCore 0x00000001bd56dfec -[UIView(Internal) _addSubview:positioned:relativeTo:] + 1903 6 UIKitCore 0x00000001bda57ccc -[_UITextLayoutCanvasView textViewportLayoutController:configureRenderingSurfaceForTextLayoutFragment:] + 455 7 UIFoundation 0x00000001c588bc9c __48-[NSTextViewportLayoutController layoutViewport]_block_invoke_4 + 151 8 UIFoundation 0x00000001c5836b50 __80-[NSTextLayoutManager enumerateViewportElementsFromLocation:options:usingBlock:]_block_invoke + 43 9 UIFoundation 0x00000001c580e158 __83-[NSTextLayoutManager enumerateTextLayoutFragmentsFromLocation:options:usingBlock:]_block_invoke_2 + 535 10 CoreFoundation 0x00000001bb385350 __NSARRAY_IS_CALLING_OUT_TO_A_BLOCK__ + 23 11 CoreFoundation 0x00000001bb3b24dc -[__NSSingleObjectArrayI enumerateObjectsWithOptions:usingBlock:] + 91 12 UIFoundation 0x00000001c580de28 __83-[NSTextLayoutManager enumerateTextLayoutFragmentsFromLocation:options:usingBlock:]_block_invoke + 775 13 UIFoundation 0x00000001c57f7504 -[NSTextLayoutManager enumerateTextLayoutFragmentsFromLocation:options:usingBlock:] + 659 14 UIFoundation 0x00000001c57f7264 -[NSTextLayoutManager enumerateViewportElementsFromLocation:options:usingBlock:] + 99 15 UIFoundation 0x00000001c57f6d7c -[NSTextViewportLayoutController layoutViewport] + 1299 16 UIKitCore 0x00000001bd580a3c +[UIView(Animation) performWithoutAnimation:] + 75 17 UIKitCore 0x00000001bd5582d0 -[_UITextLayoutCanvasView layoutSubviews] + 139 18 UIKitCore 0x00000001bd5544c8 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 1979 19 QuartzCore 0x00000001bca277fc CA::Layer::layout_if_needed(CA::Transaction*) + 499 20 QuartzCore 0x00000001bca3aeb0 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 147 21 QuartzCore 0x00000001bca4c234 CA::Context::commit_transaction(CA::Transaction*, double, double*) + 443 22 QuartzCore 0x00000001bca81630 CA::Transaction::commit() + 651 23 MediaToolbox 0x00000001ca8d0da0 videoQueueRemote_SetProperty + 367 24 AVFCore 0x00000001cad191b4 __63-[AVSampleBufferVideoRenderer _setContentLayerOnFigVideoQueue:]_block_invoke + 179 25 libdispatch.dylib 0x00000001c299cf88 _dispatch_client_callout + 19 26 libdispatch.dylib 0x00000001c29ac574 _dispatch_lane_barrier_sync_invoke_and_complete + 55 27 AVFCore 0x00000001cad190d0 -[AVSampleBufferVideoRenderer _setContentLayerOnFigVideoQueue:] + 167 28 AVFCore 0x00000001cad14674 -[AVSampleBufferVideoRenderer _createVideoQueue:errorStep:] + 195 29 AVFCore 0x00000001cad14ac8 -[AVSampleBufferVideoRenderer createVideoQueue:] + 55 30 AVFCore 0x00000001cad179cc -[AVSampleBufferVideoRenderer flushWithRemovalOfDisplayedImage:completionHandler:] + 439 31 App 0x0000000102370214 -[AVSampleBufferDisplayLayer flush] + 51

In SwiftUI there is a built-in component for displaying album artworks called Artwork but there is no equivalent for UIKit. My current approach is to use the .url() method to read image's URL and download the image or read it from the disk but the performance is much worse than it was previously with MPMediaItem's artworkImage method. let artworkQueue = DispatchQueue( label: "MusicKit-ArtworkQueue", qos: .default, attributes: .concurrent ) let artworkSemaphore = DispatchSemaphore(value: 5) extension Song { func artworkImage(for size: CGSize, completion: @escaping (UIImage?) -> Void) { artworkQueue.async { artworkSemaphore.wait() defer { artworkSemaphore.signal() } let imageURL = artwork?.url( width: Int(size.width), height: Int(size.height) ) // I hate doing this as it might very well break in the future guard let imageURL, imageURL.scheme == "musicKit" else { return completion(nil) } guard let imageData = try? Data(contentsOf: imageURL), let image = UIImage(data: imageData) else { return completion(nil) } completion(image) } } } I really dislike this approach because it feels hacky but somewhat works. You might ask what's the semaphore for? Well, without it I could notice that MusicKit was choking and after reading too many artworks at once. Can someone from Apple please provide us with an example on how to use MusicKit with UIKit properly? Ideally (IMO) we would have a method defined on Song and other MusicKit structures that returns the image for us, just like MPMediaItem had the .artwork() method. It would make our lives so much easier.

I am using MusicKit ApplicationMusicPlayer to play music in my app. Everything works fine as long as I'm not playing large playlists that contain hundreds of songs. When I to play collection of songs that is larger than around 300 I'm always getting the error message saying: "Prepare to play failed" UserInfo={NSDebugDescription=Prepare to play failed, NSUnderlyingError=0x121d42dc0 {Error Domain=MPMusicPlayerControllerErrorDomain Code=9 "Remote call timed out" UserInfo={NSDebugDescription=Remote call timed out}}})) It doesn't matter if songs are downloaded to the device or not. I am aware that there is another initializer for player's queue that accepts Playlist instances but in my app users can choose to sort playlist tracks in different order than the default and that makes using that initializer not feasible for me. I tried everything I could think of, I tried to fall back on MPMusicPlayerController and pass array of MPMusicPlayerPlayParameters to it but the result was the same. typealias QueueEntry = ApplicationMusicPlayer.Queue.Entry let player = ApplicationMusicPlayer.shared let entries: [QueueEntry] = tracks .compactMap { guard let song = $0 as? Song else { return nil } return QueueEntry(song) } Task(priority: .high) { [player] in do { player.queue = .init(entries, startingAt: nil) try await player.play() // prepareToPlay failed } catch { print(error) } }

I was wondering if anyone could assist with the following query. Apple's Private Relay functionality requires companies to register all email-sending subdomains for the service to function properly. With 26 markets and 3 subdomains per market for one department, and another department with around 20 markets and even more subdomains, the limit of 100 sending domains is exceeded. As a result, we’re unable to register all the domains currently being used to send emails to our customers. Does any have any recommendations to overcome this?

I am facing an Issue regarding the voicemail feature. when someone calls me, it would go to voicemail only if I click on the voicemail icon. If I do not respond at all to the incoming call, it does not give the caller an option to record voicemail. I have tried switching the voicemail on and off, its working on other devices Iphone 14 and 15 for my family member, just not for me. How can i resolve this?

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

Hi folks: I've been creating .reality files out of Reality Composer for over a year. Some of the files are up to 500 mB and, prior to the last month they opened fine as AR projected experiences on even basic iPhones and iPads. Now, I think since iOS 18, a 64Mb file will open as an AR experience but files it seems from about 350MB up don't open. Files just opens a window displaying the name of the file, that it's a .reality file and the file size. But it no longer opens into either an AR or Object display of the .reality scene. Has there been a new file size limit put on .reality files that Files will open or what else is going on here. Have a client who was about to launch and experience based on the .Reality file I can no longer open. Please help.

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

I am attempting to do batch Transcription of audio files exported from Voice Memos, and I am running into an interesting issue. If I only transcribe a single file it works every time, but if I try to batch it, only the last one works, and the others fail with No speech detected. I assumed it must be something about concurrency, so I implemented what I think should remove any chance of transcriptions running in parallel. And with a mocked up unit of work, everything looked good. So I added the transcription back in, and 1: It still fails on all but the last file. This happens if I am processing 10 files or just 2. 2: It no longer processes in order, any file can be the last one that succeeds. And it seems to not be related to file size. I have had paragraph sized notes finish last, but also a single short sentence that finishes last. I left the mocked processFiles() for reference. Any insights would be greatly appreciated. import Speech import SwiftUI struct ContentView: View { @State private var processing: Bool = false @State private var fileNumber: String? @State private var fileName: String? @State private var files: [URL] = [] let locale = Locale(identifier: "en-US") let recognizer: SFSpeechRecognizer? init() { self.recognizer = SFSpeechRecognizer(locale: self.locale) } var body: some View { VStack { if files.count > 0 { ZStack { ProgressView() Text(fileNumber ??

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

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?

Hi All, I am working on a DJ playout app (MACOS). The app has a few AVAudioPlayerNode's combined with the ApplicationMusicPlayer from Musickit. I can route the output of the AVaudioPlayer to a hardware device so that the audio files are directed to their own dedicated output on my Mac. The ApplicationMusicPlayer is following the default output and this is pretty annoying. Has anyone found a solution to chain the ApplicationMusicPlayer and get it set to a output device? Thanks Pancras

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!
