Hello, Environment macOS 15.6.1 / Xcode 26 beta 7 / iOS 26 Beta 9 In a simple AVFoundation video-playback sample, I’m seeing different behavior between iOS 18 and iOS 26 regarding AVPlayerItem.didPlayToEndTimeNotification. I’ve attached a minimal sample below. Please replace videoURL with a valid short video URL. Repro steps Tap “Play” to start playback and let the video finish. The AVPlayerItem.didPlayToEndTimeNotification registered with NotificationCenter should fire, and you should see Play finished. in the console. Without relaunching, tap “Play” again. This is where the issue arises. Observed behavior On iOS 18 and earlier: The video does not play again (it does not restart from the beginning), but AVPlayerItem.didPlayToEndTimeNotification is posted and Play finished. appears in the console. The same happens every time you press “Play”. On iOS 26: Pressing “Play” does not post AVPlayerItem.didPlayToEndTimeNotification. The code path that prints Play finished. is never called (the callback enclosing that line is not invoked again). Building the same program with Xcode 16.4 and running it on an iOS 26 beta device shows the same phenomenon, which suggests there has been a behavioral change for AVPlayerItem.didPlayToEndTimeNotification on iOS 26. I couldn’t find any mention of this in the release notes or API Reference. Because the semantics around AVPlayerItem.didPlayToEndTimeNotification appear to differ, we’re forced to adjust our logic. If there is a way to achieve the iOS 18–style behavior on iOS 26, I would appreciate guidance. Alternatively, if this change is intentional, could you share the reasoning? Is iOS 26 the correct behavior from Apple’s perspective and iOS 18 (and earlier) behavior considered incorrect? Any official clarification would be extremely helpful. import UIKit import AVFoundation final class ViewController: UIViewController { private let videoURL = URL(string: "https://......mp4")! private var player: AVPlayer? private var playerItem: AVPlayerItem? private var playerLayer: AVPlayerLayer? private var observeForComplete: NSObjectProtocol? // UI private let playerContainerView = UIView() private let playButton = UIButton(type: .system) private let stopButton = UIButton(type: .system) private let replayButton = UIButton(type: .system) deinit { if let observeForComplete { NotificationCenter.default.removeObserver(observeForComplete) } } override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .systemBackground setupUI() setupPlayer() } override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() playerLayer?.frame = playerContainerView.bounds } // MARK: - Setup private func setupUI() { playerContainerView.translatesAutoresizingMaskIntoConstraints = false playerContainerView.backgroundColor = .black view.addSubview(playerContainerView) // Buttons playButton.setTitle("Play", for: .normal) stopButton.setTitle("Pause", for: .normal) replayButton.setTitle("RePlay", for: .normal) [playButton, stopButton, replayButton].forEach { $0.titleLabel?.font = .systemFont(ofSize: 16, weight: .semibold) $0.translatesAutoresizingMaskIntoConstraints = false $0.contentEdgeInsets = UIEdgeInsets(top: 10, left: 16, bottom: 10, right: 16) } let stack = UIStackView(arrangedSubviews: [playButton, stopButton, replayButton]) stack.axis = .horizontal stack.spacing = 16 stack.alignment = .center stack.distribution = .equalCentering stack.translatesAutoresizingMaskIntoConstraints = false view.addSubview(stack) NSLayoutConstraint.activate([ playerContainerView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 20), playerContainerView.leadingAnchor.constraint(equalTo: view.leadingAnchor), playerContainerView.trailingAnchor.constraint(equalTo: view.trailingAnchor), playerContainerView.heightAnchor.constraint(equalToConstant: 200), stack.topAnchor.constraint(equalTo: playerContainerView.bottomAnchor, constant: 20), stack.centerXAnchor.constraint(equalTo: view.centerXAnchor) ]) // Action playButton.addTarget(self, action: #selector(didTapPlay), for: .touchUpInside) stopButton.addTarget(self, action: #selector(didTapStop), for: .touchUpInside) replayButton.addTarget(self, action: #selector(didTapReplayFromStart), for: .touchUpInside) } private func setupPlayer() { // AVURLAsset -> AVPlayerItem → AVPlayer let asset = AVURLAsset(url: videoURL) let item = AVPlayerItem(asset: asset) self.playerItem = item let player = AVPlayer(playerItem: item) player.automaticallyWaitsToMinimizeStalling = true self.player = player let layer = AVPlayerLayer(player: player) layer.videoGravity = .resizeAspect playerContainerView.layer.addSublayer(layer) layer.frame = playerContainerView.bounds self.playerLayer = layer // Notification if let observeForComplete { NotificationCenter.default.removeObserver(observeForComplete) } if let playerItem { observeForComplete = NotificationCenter.default.addObserver( forName: AVPlayerItem.didPlayToEndTimeNotification, object: playerItem, queue: .main ) { [weak self] _ in guard self != nil else { return } Task { @MainActor in print("Play finished.") } } } } // MARK: - Actions @objc private func didTapPlay() { player?.play() } @objc private func didTapStop() { player?.pause() } // RePlay @objc private func didTapReplayFromStart() { player?.seek(to: .zero, toleranceBefore: .zero, toleranceAfter: .zero) { [weak self] _ in self?.player?.play() } } } I would greatly appreciate an official response from Apple engineering on whether this is an intentional change, a regression, or an API contract clarification, and what the recommended approach is going forward. Thank you.

One thing I've noticed on tvOS 26 is that if you try to set the AVPlayerViewController customInfoViewControllers property while the Content Tabs are on screen, your app will crash. *** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'trying to add child view controller that is already presented: <AVInfoPanelViewController: 0x1030cdc00>' *** First throw call stack: (0x18a7167bc 0x189a77510 0x18a7166a8 0x1ab425658 0x1b2ee9d54 0x1b2efcd60 0x1b2eaf3f0 0x1080f744c 0x107e021a8 0x107e01b3c 0x18de41c14 0x18de41ba8 0x18de48d28 0x18ad9e358 0x101fac5f0 0x101fc6228 0x101fe7278 0x101fbc6fc 0x101fbc63c 0x18a67a2e0 0x18a679418 0x18a673b34 0x1937e4d5c 0x1abb36588 0x1abb3ae80 0x1aae9dec4 0x108610174 0x1086100e4 0x108615140 0x189abd4d0) I've logged a feedback (FB19554461) but it's getting awfully late in the dev cycle. So I've been trying to think of a workaround. The problem is that customInfoViewControllers is pretty declarative in nature. There are no properties or delegate methods I am aware of that let me know when they are displaying or not. One trick I came up with was seeing if my custom info view controller's view was "visible" or not - I put that in quotes because it turns out it can be visible even when I think it's not, as when the transport bar is scrolled to the top my custom VC still has its top pixels showing, so it gets a viewDidAppear call. So, I tried to see if my view controllers view is completely visible, ie based on the results of the GGRect contains method. And that works! But the problem is it only accounts for my own custom info view controllers, and not the standard one that Apple provides. I can't think of a way at all to know whether that is showing. Any ideas?

I'm working on a video player app that has the basic functionality of viewing a video and then be able to trim and crop that video and then save it. My flow of trimming a video and then saving it works well with any and every video. Cropping, however, doesn't work in the sense that I am unable to Save the video and export it. Whenever I crop a video, in the video player, I can see the cropped version of the video (it plays too!) but on saving said video, I get the error: Export failed with status: 4, error: Cannot Decode I've been debugging for 2 days now but I'm still unsure as to why this happens. I'm almost certain the bug is somewhere cause of cropping and then saving/exporting. If anyone has dealt with this before, please let me know what the best step to do is! If you could help me refine the flow for cropping and exporting, that'd be really helpful too. Thanks!

When creating and activating AVPictureInPictureController on iPhone 11 running iOS 18.x, the main screen viewport unexpectedly changes from the native 375×812 logical points to 414×896 points (the size of a different device such as iPhone XR/11 Plus). Additionally, a separate UIWindow with zero CGRect is created. This causes UIKit layout calculations, especially related to the keyboard and safeAreaInsets, to malfunction and results in issues like keyboard clipping and general UI misalignment. The problem appears tied specifically to iOS 18+ behavior and does not manifest on earlier iOS versions or other devices consistently. Steps to Reproduce: Run the app on iPhone 11 with iOS 18.x (including the latest minor updates). Instantiate and start an AVPictureInPictureController during app runtime. Observe that UIScreen.main.bounds changes from 375×812 (native iPhone 11 size) to 414×896. Notice a secondary UIWindow appears with frame CGRectZero. Interact with text inputs that cause the keyboard to appear. The keyboard is clipped or partially obscured, causing UI usability issues. Layout elements dependent on UIScreen.main.bounds or safeAreaInsets behave incorrectly. Expected Behavior: UIScreen.main.bounds should not dynamically change upon PiP controller creation. The coordinate space and viewport should remain accurate to device native dimensions. The keyboard and UI layout should adjust properly with respect to the actual on-screen size and safe areas. Actual Behavior: UIScreen.main.bounds changes to 414×896 upon PiP controller creation on iPhone 11 iOS 18+. A zero-rect secondary UIWindow is created, impacting layout queries. Keyboard clipping and UI layout bugs occur. The app viewport and coordinate space are inconsistent with device hardware.

Hi everyone, I'm developing a visionOS app for Apple Vision Pro, and I've encountered an issue related to window resizing at runtime when using AVPlayer to play a live HLS stream. ✅ What I'm Trying to Do Play a live HLS stream (from Wowza) inside my app using AVPlayer. Support resizing the immersive window using Vision Pro’s built-in runtime scaling gesture. Stream works fine at default window size when the app launches. ❌ Problem If I resize the app’s window at runtime (using the Vision Pro pinch-drag gesture), then try to start the stream, it does not play. Instead, it just shows the "Loading live stream..." state and never proceeds to playback. This issue only occurs after resizing the window — if I don’t resize, the stream works perfectly every time. 🧪 What I’ve Tried Verified the HLS URL — it’s working and plays fine in Safari and in the app before resizing. Set .automaticallyWaitsToMinimizeStalling = false on AVPlayer. Observed that .status on AVPlayerItem never reaches .readyToPlay after resizing. Tried to force window size back using UIWindowScene.requestGeometryUpdate(...), but behavior persists.

PLATFORM AND VERSION :iOS 18.5 I wanted to bring to your attention a critical issue some of our production users are experiencing with the CoinOut app. Specifically, users are encountering a problem when attempting to capture photos of receipts using the app's customized camera feature. The camera, which utilizes AVCaptureVideoPreviewLayer and AVCaptureDevice, occasionally fails to load the preview, resulting in a black screen instead of the expected camera view. This camera blackout issue is significantly impacting the user experience as it prevents them from snapping photos of their receipts, which is a core functionality of the CoinOut app. Any help/suggestion to this issue would be greatly appreciated. STEPS TO REPRODUCE Open the app and click on camera icon. It will display camera to capture photo.

Hi everyone, I’m trying to use AVAssetResourceLoaderDelegate to handle a live radio stream (e.g. Icecast/HTTP stream). My goal is to have access to the last 30 seconds of audio data during playback, so I can analyze it for specific audio patterns in near-real-time. I’ve implemented a custom resource loader that works fine for podcasts and static files, where the file size and content length are known. However, for infinite live streams, my current implementation stops receiving new loading requests after the first one is served. As a result, the playback either stalls or fails to continue. Has anyone successfully used AVAssetResourceLoaderDelegate with a continuous radio stream? Or maybe you can suggest betterapproach for buffering and analyzing live audio? Any tips, examples, or advice would be appreciated. Thanks!

Hello, I'm trying to subscribe to AVPlayerItem status updates using Combine and it's bridge to Swift Concurrency – .values. This is my sample code. struct ContentView: View { @State var player: AVPlayer? @State var loaded = false var body: some View { VStack { if let player { Text("loading status: \(loaded)") Spacer() VideoPlayer(player: player) Button("Load") { Task { let item = AVPlayerItem( url: URL(string: "https://sample-videos.com/video321/mp4/360/big_buck_bunny_360p_5mb.mp4")! ) player.replaceCurrentItem(with: item) let publisher = player.publisher(for: \.status) for await status in publisher.values { print(status.rawValue) if status == .readyToPlay { loaded = true break } } print("we are out") } } } else { Text("No video selected") } } .task { player = AVPlayer() } } } After I click on the "load" button it prints out 0 (as the initial status of .unknown) and nothing after – even when the video is fully loaded. At the same time this works as expected (loading status is set to true): struct ContentView: View { @State var player: AVPlayer? @State var loaded = false @State var cancellable: AnyCancellable? var body: some View { VStack { if let player { Text("loading status: \(loaded)") Spacer() VideoPlayer(player: player) Button("Load") { Task { let item = AVPlayerItem( url: URL(string: "https://sample-videos.com/video321/mp4/360/big_buck_bunny_360p_5mb.mp4")! ) player.replaceCurrentItem(with: item) let stream = AsyncStream { continuation in cancellable = item.publisher(for: \.status) .sink { if $0 == .readyToPlay { continuation.yield($0) continuation.finish() } } } for await _ in stream { loaded = true cancellable?.cancel() cancellable = nil break } } } } else { Text("No video selected") } } .task { player = AVPlayer() } } } Is this a bug or something?

Hello everyone, I'm developing a SwiftUI app that includes a fullscreen video player (AVPlayerViewController or AVPlayerLayer). I'm currently testing the app on an iPhone 16 Pro running iOS 26 Beta, as well as on the corresponding simulator. With iOS 26, during video playback, an unexpected black or white glow/halo appears around the video, depending on the system appearance (dark/light mode). However, this issue does not occur when testing on iOS 18 — neither on device nor simulator. Has anyone encountered this issue? Is there any known workaround or solution to remove this visual effect on iOS 26? I've attached screenshot below to illustrate the problem. Thank you in advance for your help!

Hi everyone, I'm working with AVPlayerViewController in a tvOS/iOS app and ran into a limitation that I believe some developers face. When using player.currentItem?.currentTime(), we only get the playback time—which is fine while the video is playing. But when the player is paused and the user drags the scrubber, there's no public API to get the time that is currently being previewed under the scrubber thumb (stick), but there's no way to read it programmatically. This becomes a problem when trying to show thumbnail previews or display metadata tied to the scrubbed position.

Is there any way we can detect the status of the Show When Muted and Show on Skip Back device settings in code ?

I’m building a SwiftUI app whose primary job is to play audio. I manage all of the Now-Playing metadata and Command center manually via the available shared instances: MPRemoteCommandCenter.shared() MPNowPlayingInfoCenter.default().nowPlayingInfo In certain parts of the app I also need to display videos, but as soon as I attach another AVPlayer, it automatically pushes its own metadata into the Control Center and overwrites my audio info. What I need: a way to show video inline without ever having that video player update the system’s Now-Playing info (or Control Center). In my app, I start by configuring the shared audio session do { try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: [ .allowAirPlay, .allowBluetoothA2DP ]) try AVAudioSession.sharedInstance().setActive(true) } catch { NSLog("%@", "**** Failed to set up AVAudioSession \(error.localizedDescription)") } and then set the MPRemoteCommandCenter commands and MPNowPlayingInfoCenter nowPlayingInfo like mentioned above. All this works without any issues as long as I only have one AVPlayer in my app. But when I add other AVPlayers to display some videos (and keep the main AVPlayer for the sound) they push undesired updates to MPNowPlayingInfoCenter: struct VideoCardView: View { @State private var player: AVPlayer let videoName: String init(player: AVPlayer = AVPlayer(), videoName: String) { self.player = player self.videoName = videoName guard let path = Bundle.main.path(forResource: videoName, ofType: nil) else { return } let url = URL(fileURLWithPath: path) let item = AVPlayerItem(url: url) self.player.replaceCurrentItem(with: item) } var body: some View { VideoPlayer(player: player) .aspectRatio(contentMode: .fill) .onAppear { player.isMuted = true player.allowsExternalPlayback = false player.actionAtItemEnd = .none player.play() MPNowPlayingInfoCenter.default().nowPlayingInfo = nil MPNowPlayingInfoCenter.default().playbackState = .stopped NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: .main) { notification in guard let finishedItem = notification.object as? AVPlayerItem, finishedItem === player.currentItem else { return } player.seek(to: .zero) player.play() } } .onDisappear { player.pause() } } } Which is why I tried adding: MPNowPlayingInfoCenter.default().nowPlayingInfo = nil MPNowPlayingInfoCenter.default().playbackState = .stopped // or .interrupted, .unknown But that didn't work. I also tried making a wrapper around the AVPlayerViewController in order to set updatesNowPlayingInfoCenter to false, but that didn’t work either: struct CustomAVPlayerView: UIViewControllerRepresentable { let player: AVPlayer func makeUIViewController(context: Context) -> AVPlayerViewController { let vc = AVPlayerViewController() vc.player = player vc.updatesNowPlayingInfoCenter = false vc.showsPlaybackControls = false return vc } func updateUIViewController(_ controller: AVPlayerViewController, context: Context) { controller.player = player } } Hence any help on how to embed video in SwiftUI without its AVPlayer touching MPNowPlayingInfoCenter would be greatly appreciated. All this was tested on an actual device with iOS 18.4.1, and built with Xcode 16.2 on macOS 15.5

I have a simple AVAudioEngine graph as follows: AVAudioPlayerNode -> AVAudioUnitEQ -> AVAudioUnitTimePitch -> AVAudioUnitReverb -> Main mixer node of AVAudioEngine. I noticed that whenever I have AVAudioUnitTimePitch or AVAudioUnitVarispeed in the graph, I noticed a very distinct crackling/popping sound in my Airpods Pro 2 when starting up the engine and playing the AVAudioPlayerNode and unable to find the reason why this is happening. When I remove the node, the crackling completely goes away. How do I fix this problem since i need the user to be able to control the pitch and rate of the audio during playback. import AVKit @Observable @MainActor class AudioEngineManager { nonisolated private let engine = AVAudioEngine() private let playerNode = AVAudioPlayerNode() private let reverb = AVAudioUnitReverb() private let pitch = AVAudioUnitTimePitch() private let eq = AVAudioUnitEQ(numberOfBands: 10) private var audioFile: AVAudioFile? private var fadePlayPauseTask: Task<Void, Error>? private var playPauseCurrentFadeTime: Double = 0 init() { setupAudioEngine() } private func setupAudioEngine() { guard let url = Bundle.main.url(forResource: "Song name goes here", withExtension: "mp3") else { print("Audio file not found") return } do { audioFile = try AVAudioFile(forReading: url) } catch { print("Failed to load audio file: \(error)") return } reverb.loadFactoryPreset(.mediumHall) reverb.wetDryMix = 50 pitch.pitch = 0 // Increase pitch by 500 cents (5 semitones) engine.attach(playerNode) engine.attach(pitch) engine.attach(reverb) engine.attach(eq) // Connect: player -> pitch -> reverb -> output engine.connect(playerNode, to: eq, format: audioFile?.processingFormat) engine.connect(eq, to: pitch, format: audioFile?.processingFormat) engine.connect(pitch, to: reverb, format: audioFile?.processingFormat) engine.connect(reverb, to: engine.mainMixerNode, format: audioFile?.processingFormat) } func prepare() { guard let audioFile else { return } playerNode.scheduleFile(audioFile, at: nil) } func play() { DispatchQueue.global().async { [weak self] in guard let self else { return } engine.prepare() try? engine.start() DispatchQueue.main.async { [weak self] in guard let self else { return } playerNode.play() fadePlayPauseTask?.cancel() playPauseCurrentFadeTime = 0 fadePlayPauseTask = Task { [weak self] in guard let self else { return } while true { let volume = updateVolume(for: playPauseCurrentFadeTime / 0.1, rising: true) // Ramp up volume until 1 is reached if volume >= 1 { break } engine.mainMixerNode.outputVolume = volume try await Task.sleep(for: .milliseconds(10)) playPauseCurrentFadeTime += 0.01 } engine.mainMixerNode.outputVolume = 1 } } } } func pause() { fadePlayPauseTask?.cancel() playPauseCurrentFadeTime = 0 fadePlayPauseTask = Task { [weak self] in guard let self else { return } while true { let volume = updateVolume(for: playPauseCurrentFadeTime / 0.1, rising: false) // Ramp down volume until 0 is reached if volume <= 0 { break } engine.mainMixerNode.outputVolume = volume try await Task.sleep(for: .milliseconds(10)) playPauseCurrentFadeTime += 0.01 } engine.mainMixerNode.outputVolume = 0 playerNode.pause() // Shut down engine once ramp down completes DispatchQueue.global().async { [weak self] in guard let self else { return } engine.pause() } } } private func updateVolume(for x: Double, rising: Bool) -> Float { if rising { // Fade in return Float(pow(x, 2) * (3.0 - 2.0 * (x))) } else { // Fade out return Float(1 - (pow(x, 2) * (3.0 - 2.0 * (x)))) } } func setPitch(_ value: Float) { pitch.pitch = value } func setReverbMix(_ value: Float) { reverb.wetDryMix = value } } struct ContentView: View { @State private var audioManager = AudioEngineManager() @State private var pitch: Float = 0 @State private var reverb: Float = 0 var body: some View { VStack(spacing: 20) { Text("🎵 Audio Player with Reverb & Pitch") .font(.title2) HStack { Button("Prepare") { audioManager.prepare() } Button("Play") { audioManager.play() } .padding() .background(Color.green) .foregroundColor(.white) .cornerRadius(10) Button("Pause") { audioManager.pause() } .padding() .background(Color.red) .foregroundColor(.white) .cornerRadius(10) } VStack { Text("Pitch: \(Int(pitch)) cents") Slider(value: $pitch, in: -2400...2400, step: 100) { _ in audioManager.setPitch(pitch) } } VStack { Text("Reverb Mix: \(Int(reverb))%") Slider(value: $reverb, in: 0...100, step: 1) { _ in audioManager.setReverbMix(reverb) } } } .padding() } }

Hello Apple Developer Community, I am trying to play an HLS stream using the React Native Video player (underneath it's using AvPlayer). I am able to play the stream smoothly, but in some cases the player can not play the stream properly. Behaviour: react-native-video: I am getting the below error. Error details from react-native-video player: Error Code: -12971 Domain: CoreMediaErrorDomain Localised Description: The operation couldn’t be completed. (CoreMediaErrorDomain error -12971.) Target: 2457 The error does not provide a specific failure reason or recovery suggestion, which makes troubleshooting challenging. AvPlayer on native iOS project: Video playback stopped after playing a few seconds. AVPlayer configuration: player.currentItem?.preferredForwardBufferDuration = 1 player.automaticallyWaitsToMinimizeStalling = true N.B.: The same buffer duration is working perfectly for others. Stream properties: video resolution: 1280 x 720 I have attached an overview report generated from MediaStreamValidator. I would appreciate any insights or suggestions on how to address this error. Has anyone in the community experienced a similar issue or have any advice on potential solutions? Thank you for your help!

Dear Developers and DTS team, This is writing to seek your expert guidance on a persistent memory leak issue I've discovered while implementing video playback in a SwiftUI application. Environment Details: iOS 17+, Swift (SwiftUI, AVKit), Xcode 16.2 Target Devices: iPhone 15 Pro (iOS 18.3.2) iPhone 16 Plus (iOS 18.3.2) Detailed Issue Description: I am experiencing consistent memory leaks when using UIViewControllerRepresentable with AVPlayerViewController for FullscreenVideoPlayer and native VideoPlayer during video playback termination. Code Context: I have implemented the following approaches: Added static func dismantleUIViewController(: coordinator:) Included deinit in Coordinator Utilized both UIViewControllerRepresentable and native VideoPlayer /// A custom AVPlayer integrated with AVPlayerViewController for fullscreen video playback. /// /// - Parameters: /// - videoURL: The URL of the video to be played. struct FullscreenVideoPlayer: UIViewControllerRepresentable { // @Binding something for controlling fullscreen let videoURL: URL? func makeUIViewController(context: Context) -> AVPlayerViewController { let controller = AVPlayerViewController() controller.delegate = context.coordinator print("AVPlayerViewController created: \(String(describing: controller))") return controller } /// Updates the `AVPlayerViewController` with the provided video URL and playback state. /// /// - Parameters: /// - uiViewController: The `AVPlayerViewController` instance to update. /// - context: The SwiftUI context for updates. func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) { guard let videoURL else { print("Invalid videoURL") return } // Initialize AVPlayer if it's not already set if uiViewController.player == nil || uiViewController.player?.currentItem == nil { uiViewController.player = AVPlayer(url: videoURL) print("AVPlayer updated: \(String(describing: uiViewController.player))") } // Handle playback state } func makeCoordinator() -> Coordinator { Coordinator(parent: self) } static func dismantleUIViewController(_ uiViewController: AVPlayerViewController, coordinator: Coordinator) { uiViewController.player?.pause() uiViewController.player?.replaceCurrentItem(with: nil) uiViewController.player = nil print("dismantleUIViewController called for \(String(describing: uiViewController))") } } extension FullscreenVideoPlayer { class Coordinator: NSObject, AVPlayerViewControllerDelegate { var parent: FullscreenVideoPlayer init(parent: FullscreenVideoPlayer) { self.parent = parent } deinit { print("Coordinator deinitialized") } } } struct ContentView: View { private let videoURL: URL? = URL(string: "https://interactive-examples.mdn.mozilla.net/media/cc0-videos/flower.mp4") var body: some View { NavigationStack { Text("My Userful View") List { Section("VideoPlayer") { NavigationLink("FullscreenVideoPlayer") { FullscreenVideoPlayer(videoURL: videoURL) .frame(height: 500) } NavigationLink("Native VideoPlayer") { VideoPlayer(player: .init(url: videoURL!)) .frame(height: 500) } } } } } } Reproducibility Steps: Run application on target devices Scenario A - FullscreenVideoPlayer: Tap FullscreenVideoPlayer Play video to completion Repeat process 5 times Scenario B - VideoPlayer: Navigate back to main screen Tap Video Player Play video to completion Repeat process 5 times Observed Memory Leak Characteristics: Per Iteration (Debug Memory Graph): 4 instances of NSMutableDictionary (Storage) leaked 4 instances of __NSDictionaryM leaked 4 × 112-byte malloc blocks leaked Cumulative Effects: Debug console prints: "dismantleUIViewController called for <AVPlayerViewController: 0x{String}> Coordinator deinitialized" when navigate back to main screen After multiple iterations, leak instances double Specific Questions: What underlying mechanisms are causing these memory leaks in UIViewControllerRepresentable and VideoPlayer? What are the recommended strategies to comprehensively prevent and resolve these memory management issues?

I am trying to stream audio from local filesystem. For that, I am trying to use an AVAssetResourceLoaderDelegate for an AVURLAsset. However, Content-Length is not known at the start. To overcome this, I tried several methods: Set content length as nil, in the AVAssetResourceLoadingContentInformationRequest Set content length to -1, in the ContentInformationRequest Both of these cause the AVPlayerItem to fail with an error. I also tried setting Content-Length as INT_MAX, and setting a renewalDate = Date(timeIntervalSinceNow: 5). However, that seems to be buggy. Even after updating the Content-Length to the correct value (e.g. X bytes) and finishing that loading request, the resource loader keeps getting requests with requestedOffset = X with dataRequest.requestsAllDataToEndOfResource = true. These requests keep coming indefinitely, and as a result it seems that the next item in the queue does not get played. Also, .AVPlayerItemDidPlayToEndTime notification does not get called. I wanted to check if this is an expected behavior or is there a bug in this implementation. Also, what is the recommended way to stream audio of unknown initial length from local file system? Thanks!
