Is anyone developing a way for users to control an iOS or PadOS device playing Apple Music to a DAC via USB to amp from another iOS or PadOS device wirelessly? Specifically, full control. Not Accessibility, not to Apple TV, not HomePods, not firmware downgraded Airport Expresses to a DAC or other hacks mentioned for the past decade this “connect” like feature has been desired by audiophiles seeking exclusive mode on a device with that (iOS/PadOS) but — control it while sitting on a couch or in a wheel chair across the room. Exclusive mode being the key feature iOS and PadOS offer that is desired with full or nearly full Apple Music control.

Issue: Under certain conditions, using CallKit does not automatically enable the microphone. Steps to Reproduce: 1.Start an outgoing call, then the user manually mutes the audio. 2.Receive a native incoming call, end the current call, then answer the new incoming call.(This order is important.) 3.End the incoming call. 4.Start another outgoing call and observe the microphone; do not manually mute or unmute. Actual Behavior: The audio icon indicates that the audio is unmuted, but the microphone remains off, and the small yellow dot in the top status bar (which represents the microphone) does not appear. Expected Behavior: The microphone should be on, consistent with the audio icon display, and the small yellow dot should appear in the top status bar. Device: iPhone 16 pro & iPhone 15 pro, iOS 18.0+ Can it be reproduced using speakerbox(CallKit Demo)? YES

In MusicKit Web the playback states are provided as numbers. For example the playbackStateDidChange event listener will return: {oldState: 2, state: 3, item:...} When the state changes from playing (2) to paused (3). Those are pretty easy to guess, but I'm having a hard time with some of the others: completed, ended, loading, none, paused, playing, seeking, stalled, stopped, waiting. I cannot find a mapping of states to numbers documented anywhere. I got the above states from an enum in a d.ts file that is often incorrect/incomplete. Can someone help out pointing to the docs or provide a mapping? Thanks.

Since the iOS 18 update, there's been a bug that always occurs when listening to music through Apple Music. When music is playing and the iPhone enters or exits standby mode, the music pauses by itself for 1 second. The initial conditions were the same as when this problem didn’t exist.

I have a recent post kind of outlining a similar question here. This time though I'm confident that inserting an array of Track works when inserting into the ApplicationMusicPlayer.shared.queue but now I'm not sure how I can initialize the queue to display song title and artwork for example. I'm also not sure how to get the current item in the queue's artist information and album information which I feel should be easy to do so maybe I'm missing something obvious. Hope this paints of what I'm trying to do and I'm going to post the neccessary code here to help me debug/figure out this problem. import SwiftUI import MusicKit struct PlayBackView: View { @Environment(\.scenePhase) var scenePhase @Environment(\.openURL) private var openURL // Adding Enum Here for Question Sake enum PlayState { case play case pause } @State var song: Track @Binding var songs: [Track]? @State var isShuffled = false @State private var playState: PlayState = .pause @State private var songTimer: Int = Int.random(in: 5...30) @State private var roundTimer: Int = 5 @State private var isTimerActive = false // @State private var volumeValue = VolumeObserver() @State private var isFirstPlay = true @State private var isDancing = false @State private var player = ApplicationMusicPlayer.shared private var isPlaying: Bool { return (player.state.playbackStatus == .playing) } let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect() var playPauseImage: String { switch playState { case .play: "pause.fill" case .pause: "play.fill" } } var body: some View { VStack { // Album Cover HStack(spacing: 20) { if let artwork = player.queue.currentEntry?.artwork { ArtworkImage(artwork, height: 100) } else { Image(systemName: "music.note") .resizable() .frame(width: 100, height: 100) } VStack(alignment: .leading) { /* This is where I want to display song title, album title, and artist name for example */ // Song Title Text(player.queue.currentEntry?.title ??

Hello, I am getting the following error while attempting to run my LockedCameraCapture compatible app on an iOS 15 device: dyld[434]: Library not loaded: '/System/Library/Frameworks/LockedCameraCapture.framework/LockedCameraCapture' Referenced from: '/private/var/containers/Bundle/Application/.../MyApp.app/MyApp.debug.dylib' Reason: tried: '/System/Library/Frameworks/LockedCameraCapture.framework/LockedCameraCapture' (no such file) Of course iOS 15 doesn't have the library for LockedCameraCapture, but I have had no issue including Lock Screen Widgets (which require iOS 16), so I am not sure why the error is popping up. Thank you!

Bug Report: ScreenCaptureKit System Audio Capture Crashes with EXC_BAD_ACCESS Summary When using ScreenCaptureKit to capture system audio for extended periods, the application crashes with EXC_BAD_ACCESS in Swift's error handling runtime. The crash occurs in swift_getErrorValue when trying to process an error from the SCStream delegate method didStopWithError. This appears to be a framework-level issue in ScreenCaptureKit or its underlying ReplayKit implementation. Environment macOS Sonoma 14.6.1 Swift 5.8 ScreenCaptureKit framework Detailed Description Our application captures system audio using ScreenCaptureKit's audio capture capabilities. After successfully capturing for several minutes (typically after 3-4 segments of 60-second recordings), the application crashes with an EXC_BAD_ACCESS error. The crash happens when the Swift runtime attempts to process an error in the SCStreamDelegate.stream(_:didStopWithError:) method. The crash consistently occurs in swift_getErrorValue when attempting to access the class of what appears to be a null object. This suggests that the error being passed from the system framework to our delegate method is malformed or contains invalid memory. Steps to Reproduce Create an SCStream with audio capture enabled Add audio output to the stream Start capture and write audio data to disk Allow the capture to run for several minutes (3-5 minutes typically triggers the issue) The app will crash with EXC_BAD_ACCESS in swift_getErrorValue Code Sample func stream(_ stream: SCStream, didStopWithError error: Error) { print("Stream stopped with error: \(error)") // Crash occurs before this line executes } func stream(_ stream: SCStream, didOutputSampleBuffer sampleBuffer: CMSampleBuffer, of type: SCStreamOutputType) { guard type == .audio, sampleBuffer.isValid else { return } // Process audio data... } Expected Behavior The error should be properly propagated to the delegate method, allowing for graceful error handling and recovery. Actual Behavior The application crashes with EXC_BAD_ACCESS when the Swift runtime attempts to process the error in swift_getErrorValue.

Impact This issue prevents reliable long-duration audio capture using ScreenCaptureKit. This bug significantly limits the usefulness of ScreenCaptureKit for any application requiring continuous system audio capture for more than a few minutes. Perhaps this issue might be related to a macOS bug where the system dialog indicates that the screen is being shared, even though nothing is actually being shared. Moreover, when attempting to stop sharing, nothing happens.

Iphone 13mini updated to ios18. Carplay is wired on my 2021 RAM Laramie. After the update => Premium audio is lost, I can only hear low quality audio. When I manually change to Bluetooth instead of usb on the car, then audio comes in speaker mode on my phone and not on the truck.

I would appreciate help in coding or an explanation what to use in swift for an app which will be able to capture LiDAR scanning and RGB data from taken pictures, generate a 3D mesh, and create .OBJ, .MTL, and .JPEG file set for further manipulation of 3D model.

Hi all, I have been quite stumped on this behavior for a little bit now, so thought it best to share here and see if someone more experience with AVAudioEngine / AVAudioSession can weigh in. Right now I have a AVAudioEngine that I am using to perform some voice chat with and give buffers to play. This works perfectly until route changes start to occur, which causes the AVAudioEngine to reset itself, which then causes all players attached to this engine to be stopped. Once a AVPlayerNode gets stopped due to this (but also any other time), all samples that were scheduled to be played then get purged. Where this becomes confusing for me is the completion handler gets called every time regardless of the sound actually being played. Is there a reliable way to know if a sample needs to be rescheduled after a player has been reset? I am not quite sure in my case what my observer of AVAudioEngineConfigurationChange needs to be doing, as this engine only handles output. All input is through a separate engine for simplicity. Currently I am storing a queue of samples as they get sent to the AVPlayerNode for playback, and after that completion checking if the player isPlaying or not. If it's playing I assume that the sound actually was played- and if not then I leave it in the queue and assume that an observer on the route change or the configuration change will realize there are samples in the queue and reset them Thanks for any feedback!

I am would like to look at AVMetricEvent data during video playback, so I have added this code to a test video player app: let playerItem: AVPlayerItem = ... let allMetrics = playerItem.allMetrics() Task.init { print("metrics task started") do { for try await metricEvent in allMetrics { print("metric event: \(metricEvent.description)") } } catch { print("unexpected metric iterator error \(error)") } } Running this in Simulator on iPhone 16 Pro (18.0) does not result in any "metric event" diagnostic messages being printed when the video associated with this AVPlayerItem is playing. Only the "metric task started" diagnostic message is seen. What am I doing wrong that prevents metric data being received?

Hello ! I am working on an app connected to an external streamer . I would like to display current playing song on the Lock Screen. I tried to update the information in MPNowPlayingInfoCenter but I need to play a sound on my iPhone for the control to be displayed . Is there a way to do it without playing a sound? If not, playing a silent sound would be the only solution ? validated by Apple ? :-/ Thank you Frederic

Hi, just generated a HDR10 MVHEVC file, mediainfo is below: Color range : Limited Color primaries : BT.2020 Transfer characteristics : PQ Matrix coefficients : BT.2020 non-constant Codec configuration box : hvcC+lhvC then generate the segment files with below command: mediafilesegmenter --iso-fragmented -t 4 -f av_1 av_new_1.mov then upload the segment files and prog_index.m3u8 to web server. just find that can not play the HLS stream on Safari... the url is http://ip/vod/prog_index.m3u8 just checked that if i remove the tag Transfer characteristics : PQ when generating the MVHEVC file. above same mediafilesegmenter command and upload the files to web server. the new version of HLS stream is can play on Safari... Is there any way to play HLS PQ video on Safari. thanks.

Hi, trying to wrap my head around Xcode's FXPlug. I already sell Final Cut Pro titles for a company. These titles were built in motion. However, they want me to move them to an app and I'm looking for any help on how to accomplish this *What the app should do is: Allow users with an active subscription to our website the ability to access titles within FCPX and if they are not an active subscriber, for access to be denied.

I am trying to use AVCaptureDevice.rotationCoordinator API to observe angles for preview and capture and it seems there is an issue with the API when used with arbitrary CALayer (which is not a AVCaptureVideoPreviewLayer) and switching cameras. Here is my setup. The below function is defined in an actor class called CameraManager that performs setup of rotationCoordinator. func updateRotationCoordinator(_ callback:@escaping @MainActor (CGFloat) -> Void) { guard let device = sessionConfiguration.activeVideoInput?.device, let displayLayer = displayLayer else { return } cancellables.removeAll() rotationCoordinator = AVCaptureDevice.RotationCoordinator(device: device, previewLayer: displayLayer) guard let coordinator = rotationCoordinator else { return } coordinator.publisher(for: \.videoRotationAngleForHorizonLevelPreview) .receive(on: DispatchQueue.main) .sink { degrees in let radians = degrees * .pi / 180 MainActor.assumeIsolated { callback(radians) } } .store(in: &cancellables) } This works the very first time but when I switch cameras and call this function again, it throws a runtime error that view's layer is modified from a non-main thread. This happens at the very line where rotation coordinator is been recreated. It's not clear why initialising rotation coordinator should modify CALayer properties right in it's init method. Modifying properties of a view's layer off the main thread is not allowed: view <MyApp.DisplayLayerView: 0x102ffaf40> with nearest ancestor view controller <_TtGC7SwiftUI19UIHostingControllerGVS_15ModifiedContentVS_7AnyViewVS_12RootModifier__: 0x101f7fb80>; backtrace: ( 0 UIKitCore 0x0000000194a977b4 575E5140-FA6A-37C2-B00B-A4EACEDFDA53 + 22509492 1 UIKitCore 0x000000019358594c 575E5140-FA6A-37C2-B00B-A4EACEDFDA53 + 416076 2 QuartzCore 0x00000001927f5bd8 D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 43992 3 QuartzCore 0x00000001927f5a4c D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 43596 4 QuartzCore 0x000000019283a41c D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 324636 5 QuartzCore 0x000000019283a0a8 D8E8E86D-85AC-3C90-B2E1-940235ECAA18 + 323752 6 AVFCapture 0x00000001af072a18 09192166-E0B6-346C-B1C2-7C95C3EFF7F7 + 420376 7 MyApp.debug.dylib 0x0000000105fa3914 $s10MyApp15CapturePipelineC25updateRotationCoordinatoryyy12CoreGraphics7CGFloatVScMYccF + 972 8 MyApp.debug.dylib 0x00000001063ade40 $s10MyApp11CameraModelC18switchVideoDevicesyyYaFTY3_ + 72 9 MyApp.debug.dylib 0x0000000105fe3cbd $s10MyApp11ContentViewV4bodyQrvg7SwiftUI6VStackVyAE05TupleE0VyAE6HStackVyAIyAE6SpacerV_AE6ButtonVyAE0E0PAEE5frame5width6height9alignmentQr12CoreGraphics7CGFloatVSg_AyE9AlignmentVtFQOyAqEE11scaledToFitQryFQOyAqEE10imageScaleyQrAE5ImageV0Z0OFQOyA3__Qo__Qo__Qo_GtGG_AmKyAIyAKyAIyAqEE7paddingyQrAE4EdgeO3SetV_AYtFQOyAA07CaptureM0V_Qo__AOyAE4TextVGAmKyAIyA9__AqEEArstUQrAY_AYA_tFQOyAM_Qo_A9_tGGtGG_AmqEE10background_AUQrqd___A_tAePRd__lFQOyAqEEArstUQrAY_AYA_tFQOyA21__Qo__AqEEArstUQrAY_AYA_tFQOyAE06_ShapeE0VyAE9RectangleVAE5ColorVG_Qo_Qo_SgtGGtGGyXEfU0_A42_yXEfU_A10_yXEfU_yyScMYccfU_yyYacfU_TQ1_ + 1 10 MyApp.debug.dylib 0x0000000105ff06d9 $s10MyApp11ContentViewV4bodyQrvg7SwiftUI6VStackVyAE05TupleE0VyAE6HStackVyAIyAE6SpacerV_AE6ButtonVyAE0E0PAEE5frame5width6height9alignmentQr12CoreGraphics7CGFloatVSg_AyE9AlignmentVtFQOyAqEE11scaledToFitQryFQOyAqEE10imageScaleyQrAE5ImageV0Z0OFQOyA3__Qo__Qo__Qo_GtGG_AmKyAIyAKyAIyAqEE7paddingyQrAE4EdgeO3SetV_AYtFQOyAA07CaptureM0V_Qo__AOyAE4TextVGAmKyAIyA9__AqEEArstUQrAY_AYA_tFQOyAM_Qo_A9_tGGtGG_AmqEE10background_AUQrqd___A_tAePRd__lFQOyAqEEArstUQrAY_AYA_tFQOyA21__Qo__AqEEArstUQrAY_AYA_tFQOyAE06_ShapeE0VyAE9RectangleVAE5ColorVG_Qo_Qo_SgtGGtGGyXEfU0_A42_yXEfU_A10_yXEfU_yyScMYccfU_yyYacfU_TATQ0_ + 1 11 MyApp.debug.dylib 0x0000000105f9c595 $sxIeAgHr_xs5Error_pIegHrzo_s8SendableRzs5NeverORs_r0_lTRTQ0_ + 1 12 MyApp.debug.dylib 0x0000000105f9fb3d $sxIeAgHr_xs5Error_pIegHrzo_s8SendableRzs5NeverORs_r0_lTRTATQ0_ + 1 13 libswift_Concurrency.dylib 0x000000019c49fe39 E15CC6EE-9354-3CE5-AF91-F641CA8283E0 + 433721 )

Hi, I’m working on a photo backup app. I track the PHAsset localIdentifier to determine which photos have been backed up and which haven’t. Recently, I’ve noticed that two users seem to have experienced the localIdentifier changes after transferring data to a new iPhone using Quick Start. Additionally, others on StackOverflow have mentioned that the localIdentifier sometimes changes after updating the iOS version. https://stackoverflow.com/questions/40094728/phobject-localidentifier-reliability I’d like to confirm the reliability of the localIdentifier after an iOS version upgrade or device transfer. Can I continue using these locally stored localIdentifiers? Or is there another recommended approach, such as using PHCloudIdentifier?

We have a VOIP calling application that releases resources at the end of call. When the AudioOutputUnitStop API is invoked, it takes upto 700millisecond to return back sometimes. If we comment that API call as a test then the AudioUnitUninitialize API takes upto 700ms. Once the cleanup is done, as part of the call flow, the application invokes a BYE SIP message. Hence in cases where the API takes more than 200 ms, the Bye message is sent with that much delay and gets blocked as per the server DDOS settings. (DDOS timer will start as soon as a the UDP socket is disconnected with the client and will timeout within 200 ms and Bye request coming post that time will get blocked) We need to understand why there is a delay of more than 200ms observed sometimes while in other cases it requires less than 50ms?

I have noticed a problem when a PHAsset creation request is made with the resource type PHAssetResourceType.photoProxy. let creationRequest = PHAssetCreationRequest.forAsset() creationRequest.addResource(with: .photoProxy, data: photoData, options: nil) creationRequest.location = location creationRequest.isFavorite = true After successfully saving the resulting asset through PHPhotoLibrary.shared().performChanges, I could verify it in the Photos app. I noticed that the created photo was initially marked as Favorite and that the location was added to the info as expected. The title of the image changes from "Today" to "" too. Next, the photo was refreshed, and location data was purged. However, the title remains unchanged and displays the . This refresh was also observed in the code. PHPhotoLibraryChangeObserver protocols func photoLibraryDidChange(_ changeInstance: PHChange) receives a change notification. The same asset has been changed, and there is no location information anymore. isFavorite information persists correctly. After debugging for a few hours, I discovered that changing the resource type to .photo fixes this issue. Location data is not removed in the Photos app, and no refresh callback is seen in func photoLibraryDidChange(_ changeInstance: PHChange). I initially used .photoProxy because in the AVCapturePhotoCaptureDelegate implementation class, I always get the call in func photoOutput(_ output: AVCapturePhotoOutput, didFinishCapturingDeferredPhotoProxy deferredPhotoProxy: AVCaptureDeferredPhotoProxy?, error: Error?). So here is where I am capturing the photo data as photoData = deferredPhotoProxy?.fileDataRepresentation().
