Because I want to control the grid size and number of HEIC images myself, I decided to perform HEVC encoding manually and then generate the HEIC image. Previously, I used VTCompressionSession to accomplish this task, and the results were satisfactory. It worked perfectly on iOS 16 through iOS 18 — in other words, it was able to generate correct HEVC encoding, and its CMFormatDescription should also have been correct, since I relied on it to generate the decoderConfig; otherwise, the final image would have decoding issues. However, it can no longer generate a valid HEIC image on a physical device running iOS 26. Interestingly, it still works fine on the iOS 26 simulator — it only fails on real hardware. The abnormal result is that the image becomes completely black, although the image dimensions are still correct. After my troubleshooting, I suspect that the encoding behavior of VTCompressionSession has been modified on iOS 26, which causes the final hvc1 encoding I pass in to be incorrect. I created a VTCompressionSession using the following configuration. var newSession: VTCompressionSession! var status = VTCompressionSessionCreate( allocator: kCFAllocatorDefault, width: Int32(frameSize.width), height: Int32(frameSize.height), codecType: kCMVideoCodecType_HEVC, encoderSpecification: nil, imageBufferAttributes: nil, compressedDataAllocator: nil, outputCallback: nil, refcon: nil, compressionSessionOut: &newSession ) try check(status, VideoToolboxErrorDomain) let properties: [CFString: Any] = [ kVTCompressionPropertyKey_AllowFrameReordering: false, kVTCompressionPropertyKey_AllowTemporalCompression: false, kVTCompressionPropertyKey_RealTime: false, kVTCompressionPropertyKey_MaximizePowerEfficiency: false, kVTCompressionPropertyKey_ProfileLevel: profileLevel, kVTCompressionPropertyKey_Quality: quality.rawValue, ] status = VTSessionSetProperties(newSession, propertyDictionary: properties as CFDictionary) try check(status, VideoToolboxErrorDomain) { VTCompressionSessionInvalidate(newSession) } Then use the following code to encode each Grid of the image. let status = VTCompressionSessionEncodeFrame( session, imageBuffer: buffer, presentationTimeStamp: presentationTimeStamp, duration: frameDuration, frameProperties: nil, infoFlagsOut: nil) { [weak self] status, _, sampleBuffer in try check(status, VideoToolboxErrorDomain) if let sampleBuffer { let encodedImage = try self.encodedImage(from: sampleBuffer) // handle encodedImage } } try check(status, VideoToolboxErrorDomain) If I try to display this abnormal image in the App, my console outputs the following error, so it can be inferred that the issue probably occurred during decoding. createImageBlock:3029: *** ERROR: CGImageBlockCreate {0, 0, 2316, 6176} - data is NULL callDecodeImage:2411: *** ERROR: decodeImageImp failed - NULL _blockArray createImageBlock:3029: *** ERROR: CGImageBlockCreate {0, 0, 2316, 6176} - data is NULL callDecodeImage:2411: *** ERROR: decodeImageImp failed - NULL _blockArray createImageBlock:3029: *** ERROR: CGImageBlockCreate {0, 0, 2316, 6176} - data is NULL callDecodeImage:2411: *** ERROR: decodeImageImp failed - NULL _blockArray It needs to be emphasized again that this code used to work fine in the past, and the issue only occurs on an iOS 26 physical device. I noticed that iOS 26 has introduced many new properties, but I’m not sure whether some of these new properties must be set in the new system, and there’s no information about this in the official documentation.

Hello, I used kAudioDevicePropertyDeviceIsRunningSomewhere to check if an internal or external microphone is being used. My code works well for the internal microphone, and for microphones which are connected using a cable. External microphones which are connected using bluetooth are not reporting their status. The status is always requested successfully, but it is always reported as inactive. Main relevant parts in my code : static inline AudioObjectPropertyAddress makeGlobalPropertyAddress(AudioObjectPropertySelector selector) { AudioObjectPropertyAddress address = { selector, kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyElementMaster, }; return address; } static BOOL getBoolProperty(AudioDeviceID deviceID, AudioObjectPropertySelector selector) { AudioObjectPropertyAddress const address = makeGlobalPropertyAddress(selector); UInt32 prop; UInt32 propSize = sizeof(prop); OSStatus const status = AudioObjectGetPropertyData(deviceID, &address, 0, NULL, &propSize, &prop); if (status != noErr) { return 0; //this line never gets executed in my tests. The call above always succeeds, but it always gives back "false" status. } return static_cast<BOOL>(prop == 1); } ... __block BOOL microphoneActive = NO; iterateThroughAllInputDevices(^(AudioObjectID object, BOOL *stop) { if (getBoolProperty(object, kAudioDevicePropertyDeviceIsRunningSomewhere) != 0) { microphoneActive = YES; *stop = YES; } }); What could cause this and how could it be fixed? Thank you for your help in advance!

Hello, Faced with a really perplexing issue. Primary problem is that sometimes I get depth and video data as expected, but at other times I don't. And sometimes I'll get both data outputs for a 4-5 frames and then it'll just stop. The source code I implemented is a modified version of the sample code provided by Apple, and interestingly enough I can't re-create this issue with the Apple sample app. So wondering what I could be doing wrong? Here's the code for setting up the capture input. preferredDepthResolution is 1280 in my case. I'm running this on an iPad Pro (6th gen). iOS version 17.0.3 (21A360). Encounter this issue on iPhone 13 Pro as well. iOS version is 17.0 (21A329) private func setupLiDARCaptureInput() throws { // Look up the LiDAR camera. guard let device = AVCaptureDevice.default(.builtInLiDARDepthCamera, for: .video, position: .back) else { throw ConfigurationError.lidarDeviceUnavailable } guard let format = (device.formats.last { format in format.formatDescription.dimensions.width == preferredWidthResolution && format.formatDescription.mediaSubType.rawValue == kCVPixelFormatType_420YpCbCr8BiPlanarFullRange && format.videoSupportedFrameRateRanges.first(where: {$0.maxFrameRate >= 60}) != nil && !format.isVideoBinned && !format.supportedDepthDataFormats.isEmpty }) else { throw ConfigurationError.requiredFormatUnavailable } guard let depthFormat = (format.supportedDepthDataFormats.last { depthFormat in depthFormat.formatDescription.mediaSubType.rawValue == kCVPixelFormatType_DepthFloat16 }) else { throw ConfigurationError.requiredFormatUnavailable } // Begin the device configuration. try device.lockForConfiguration() // Configure the device and depth formats. device.activeFormat = format device.activeDepthDataFormat = depthFormat let desc = format.formatDescription dimensions = CMVideoFormatDescriptionGetDimensions(desc) let duration = CMTime(value:1, timescale:CMTimeScale(60)) device.activeVideoMinFrameDuration = duration device.activeVideoMaxFrameDuration = duration // Finish the device configuration. device.unlockForConfiguration() self.device = device print("Selected video format: \(device.activeFormat)") print("Selected depth format: \(String(describing: device.activeDepthDataFormat))") // Add a device input to the capture session. let deviceInput = try AVCaptureDeviceInput(device: device) captureSession.addInput(deviceInput) guard let audioDevice = AVCaptureDevice.default(for: .audio) else { return } // Configure audio input - always configure audio even if isAudioEnabled is false audioDeviceInput = try! AVCaptureDeviceInput(device: audioDevice) captureSession.addInput(audioDeviceInput) deviceSystemPressureStateObservation = device.observe( \.systemPressureState, options: .new ) { _, change in guard let systemPressureState = change.newValue else { return } print("system pressure \(systemPressureState.levelAsString()) due to \(systemPressureState.factors)") } } Here's how I'm setting up the output: private func setupLiDARCaptureOutputs() { // Create an object to output video sample buffers. videoDataOutput = AVCaptureVideoDataOutput() captureSession.addOutput(videoDataOutput) // Create an object to output depth data. depthDataOutput = AVCaptureDepthDataOutput() depthDataOutput.isFilteringEnabled = false captureSession.addOutput(depthDataOutput) audioDeviceOutput = AVCaptureAudioDataOutput() audioDeviceOutput.setSampleBufferDelegate(self, queue: videoQueue) captureSession.addOutput(audioDeviceOutput) // Create an object to synchronize the delivery of depth and video data. outputVideoSync = AVCaptureDataOutputSynchronizer(dataOutputs: [depthDataOutput, videoDataOutput]) outputVideoSync.setDelegate(self, queue: videoQueue) // Enable camera intrinsics matrix delivery. guard let outputConnection = videoDataOutput.connection(with: .video) else { return } if outputConnection.isCameraIntrinsicMatrixDeliverySupported { outputConnection.isCameraIntrinsicMatrixDeliveryEnabled = true } } The top part of my delegate implementation is as follows: func dataOutputSynchronizer( _ synchronizer: AVCaptureDataOutputSynchronizer, didOutput synchronizedDataCollection: AVCaptureSynchronizedDataCollection ) { // Retrieve the synchronized depth and sample buffer container objects. guard let syncedDepthData = synchronizedDataCollection.synchronizedData(for: depthDataOutput) as? AVCaptureSynchronizedDepthData, let syncedVideoData = synchronizedDataCollection.synchronizedData(for: videoDataOutput) as? AVCaptureSynchronizedSampleBufferData else { if synchronizedDataCollection.synchronizedData(for: depthDataOutput) == nil { print("no depth data at time \(mach_absolute_time())") } if synchronizedDataCollection.synchronizedData(for: videoDataOutput) == nil { print("no video data at time \(mach_absolute_time())") } return } print("received depth data \(mach_absolute_time())") } As you can see, I'm console logging whenever depth data is not received. Note because I'm driving the video frames at 60 fps, its expected that I'll only receive depth data for every alternate video frame. Console output is posted as a follow up comment (because of the character limit). I edited some lines out for brevity. You'll see it started streaming correctly but after a while it stopped received both video and depth outputs (in some other runs, it works perfectly and in some other runs I receive no depth data whatsoever). One thing to note, I sometimes run quicktime mirroring to see the device screen to see what the app is displaying (so not sure if that's causing any interference - that said I don't see any system pressure changes either). Any help is most appreciated! Thanks.

I had no luck to compile a sample code provided by apple with Xcode 16.0 beta 5. ScreenCaptureKit demo (https://developer.apple.com/documentation/screencapturekit/capturing_screen_content_in_macos) The part it is failling is, streamOutput.capturedFrameHandler = { continuation.yield($0) } And the error message is Sending '$0' risks causing data races Task-isolated '$0' is passed as a 'sending' parameter; Uses in callee may race with later task-isolated uses Please enlighten me why this is an issue and how to avoid? Thanks in advance!

We move to another streaming service and need to deliver a ASK, .PEM &amp;key, and CRT to enable DRM. Now the issue is that we don't have that information anymore. Most logical would be to revoke the current certificate and create a new one. Unfortunately for Fairplay Streaming Certificates there is no revoke button. We asked developer support who isn't able to help. We then did a request to revoke as described in article 2.7 of the Apple Developer Program License Agreement. They can only do this when the certificate is compromised. So now we are stuck. Anyone out there who had the same issue and found a solution? Your help is much appreciated.

I donate INPlayMediaIntent to systerm（donate success）, but not show in control center My code is as follows let mediaItems = mediaItems.map { $0.inMediaItem } let intent = if #available(iOS 13.0, *) { INPlayMediaIntent(mediaItems: mediaItems, mediaContainer: nil, playShuffled: false, playbackRepeatMode: .none, resumePlayback: true, playbackQueueLocation: .now, playbackSpeed: nil, mediaSearch: nil) } else { INPlayMediaIntent(mediaItems: mediaItems, mediaContainer: nil, playShuffled: false, playbackRepeatMode: .none, resumePlayback: true) } intent.suggestedInvocationPhrase = "播放音乐" let interaction = INInteraction(intent: intent, response: nil) interaction.donate { error in if let error = error { print("Intent 捐赠失败: \(error.localizedDescription)") } else { print("Intent 捐赠成功 ✅") } }

We have observed consistent glitches in video playback when using AVPlayer to stream HLS (HTTP Live Streaming) videos on iOS. The issue manifests as intermittent frame drops, stuttering, and playback instability during HLS streams. However, the same behavior is not present when playing MP4 videos using the same AVPlayer instance. The HLS streams being used follow standard encoding practices, and network conditions have been ruled out as a cause for this problem. https://drive.google.com/file/d/1lhdpHTyjPYCYLHjzvb6ZF6P6jehIuwY0/view?usp=sharing Steps to Reproduce: 1. Load an HLS video into AVPlayer and initiate playback. 2. Observe intermittent glitches and stuttering during video playback. 3. Load and play an MP4 video in the same AVPlayer instance. 4. Notice that MP4 playback is smooth without any glitches.

i have a CarPlay implementation eand I want to show previous/next track button on player UI MPRemoteCommandCenter.shared().seekForwardCommand.isEnabled = false MPRemoteCommandCenter.shared().seekBackwardCommand.isEnabled = false MPRemoteCommandCenter.shared().previousTrackCommand.isEnabled = true MPRemoteCommandCenter.shared().nextTrackCommand.isEnabled = true It works correctly on CarPlay simulator , but on some car only SEEK button are shown . I have to suppose that it is that a problem on the car side , but I would ask about your opinion , maybe there is some pieces I'm missing

Hello, I am trying to get my camera app to launch from the Lock Screen, and see that calls to UIApplication.shared are not allowed. In my app, I have: UIApplication.shared.isIdleTimerDisabled = true Which is causing this compile time error: 'shared' is unavailable in application extensions for iOS: Use view controller based solutions where appropriate instead I do not believe there is a view controller based solution for this. Is there a flag I can wrap around the call so that the compiler knows it won't be used during an application extension? Thank you!

Hi, Apple's engineer. Hoping that you can reply to this one. We're developing a Text-to-Speak app. Everything went well until the IOS got upgraded to 18. AVSpeechSynthesisVoice(language: "zh-CN") is running well under IOS 16 AND IOS 17. It speaks Mandarin correctly. In IOS 18, we noticed that Siri's Language setting interrupted the performance of AVSpeechSynthesisVoice. It plays Cantonese instead of Mandarin. Buggy language setting in Siri that affects the AVSpeechSynthesisVoice : Chinese (Cantonese - China mainland) Chinese (Cantonese -Hong Kong)

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)) } } }

Hi, I just started to develop audio unit hosting support in my application. Offline rendering seems to work except that I hear no output, but why? I suspect with the player goes something wrong. I connect to CoreAudio in a different location in the code. Here are some error messages I faced so far: 2025-08-14 19:42:04.132930+0200 com.gsequencer.GSequencer[34358:18611871] [avae] AVAudioEngineGraph.mm:4668 Can't retrieve source node to play sequence because there is no output node! 2025-08-14 19:42:04.151171+0200 com.gsequencer.GSequencer[34358:18611871] [avae] AVAudioEngineGraph.mm:4668 Can't retrieve source node to play sequence because there is no output node! 2025-08-14 19:43:08.344530+0200 com.gsequencer.GSequencer[34358:18614927] AUAudioUnit.mm:1417 Cannot set maximumFramesToRender while render resources allocated. 2025-08-14 19:43:08.346583+0200 com.gsequencer.GSequencer[34358:18614927] [avae] AVAEInternal.h:104 [AVAudioSequencer.mm:121:-[AVAudioSequencer(AVAudioSequencer_Player) startAndReturnError:]: (impl->Start()): error -10852 ** (<unknown>:34358): WARNING **: 19:43:08.346: error during audio sequencer start - -10852 I have implemented an AVAudioEngine based AudioUnit host.

I started playing which transcription of audio files on macOS today, latest beta of Xcode and latest beta of Tahoe. Transcription itself works really well, but for some reason the majority of the results contain no audioTimeRange. I got 22 single-word results with time ranges, spread out all over total file of 53 minutes. Is there something I can do to improve this? To my understanding, I have followed sample code and instructions very closely, but the SwiftTranscriptionSampleApp and other examples I've seen lead me to believe I should be getting a lot more time ranges than I actually do.

We are currently in the process of migrating our application from using ALAssetsLibrary to PHPhotoLibrary to ensure compatibility with the latest versions of iOS. However, we have noticed a discrepancy in the file sizes of images obtained using PHPhotoLibrary compared to those obtained using ALAssetsLibrary. Specifically, we would like to understand the following points: 1.Reason for File Size Differences: What are the reasons for the difference in file sizes between images obtained using ALAssetsLibrary and those obtained using PHPhotoLibrary? Could you provide detailed information on the settings and options in PHPhotoLibrary that affect the size and quality of the images? 2.Optimal Settings: What are the optimal settings in PHPhotoLibrary to obtain images with the same quality and file size as those obtained using ALAssetsLibrary? If possible, could you provide code examples or recommended option settings?

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.

I have an app that plays sound files stored locally. I'm using a single SwiftUI view with a MPVolumeView so the user can control system volume from the player in my app. When I'm playing the sound file on the iPhone, my volume slider operates as expected. When I AirPlay to my AppleTV, the volume slider still works to control the volume, but when I hit play in my app, the volume snaps to a different value, but actual sound volume doesn't change. Control still works. Flipping to control center, I see a volume mismatch between system volume and the MPVolumeView. Here's the code that I use to put the slider in my app. struct VolumeSlider: UIViewRepresentable { func makeUIView(context: Context) -> MPVolumeView { let vv = MPVolumeView(frame: .zero) vv.showsVolumeSlider = true vv.setVolumeThumbImage(UIImage() ,for: UIControl.State.normal) return vv } func updateUIView(_ uiView: MPVolumeView, context: Context) { // No need to update the view in this case } } I'm using AVFoundation and AVAudioPlayer to playback the sound file. I'm using MediaPlayer to tell MPNowPlayingInfoCenter the track info and AlbumArt. Audio control via control center works perfectly. Does the same if I target iOS 16 or 17. Is this a bug with the MPVolumeView or the way I added it to the app?

I'm working on an app where a user needs to select a video from their Photos library, and I need to get the original, unmodified HEVC (H.265) data stream to preserve its encoding. The Problem I have confirmed that my source videos are HEVC. I can record a new video with my iPhone 15 Pro Max camera set to "High Efficiency," export the "Unmodified Original" from Photos on my Mac, and verify that the codec is MPEG-H Part2/HEVC (H.265). However, when I select that exact same video in my app using PHPickerViewController, the itemProvider does not list public.hevc as an available type identifier. This forces me to fall back to a generic movie type, which results in the system providing me with a transcoded H.264 version of the video. Here is the debug output from my app after selecting a known HEVC video: ⚠️ 'public.hevc' not found. Falling back to generic movie type (likely H.264). What I've Tried My code explicitly checks for the public.hevc identifier in the registeredTypeIdentifiers array. Since it's not found, my HEVC-specific logic is never triggered. Here is a minimal version of my PHPickerViewControllerDelegate implementation: import UniformTypeIdentifiers // ... inside the Coordinator class ... func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { picker.dismiss(animated: true) guard let result = results.first else { return } let itemProvider = result.itemProvider let hevcIdentifier = "public.hevc" let identifiers = itemProvider.registeredTypeIdentifiers print("Available formats from itemProvider: \(identifiers)") if identifiers.contains(hevcIdentifier) { print("✅ HEVC format found, requesting raw data...") itemProvider.loadDataRepresentation(forTypeIdentifier: hevcIdentifier) { (data, error) in // ... process H.265 data ... } } else { print("⚠️ 'public.hevc' not found. Falling back to generic movie type (likely H.264).") itemProvider.loadFileRepresentation(forTypeIdentifier: UTType.movie.identifier) { url, error in // ... process H.264 fallback ... } } } My Environment Device: iPhone 15 Pro Max iOS Version: iOS 18.5 Xcode Version: 16.2 My Questions Are there specific conditions (e.g., the video being HDR/Dolby Vision, Cinematic, or stored in iCloud) under which PHPickerViewController's itemProvider would intentionally not offer the public.hevc type identifier, even for an HEVC video? What is the definitive, recommended API sequence to guarantee that I receive the original, unmodified data stream for a video asset, ensuring that no transcoding to H.264 occurs during the process? Any insight into why public.hevc might be missing from the registeredTypeIdentifiers for a known HEVC asset would be greatly appreciated. Thank you.

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.
