According to https://developer.apple.com/download/files/CarPlay-Developer-Guide.pdf , apps with entitlement com.apple.developer.carplay-driving-task are allowed to use voice control. In my current implementation the voice recording working fine but the voice response (AVPlayer with category "playback set") does not output any audio. I suspect that it is a entitlement limitation because if I quickly tap to play a music while the voice assistant AVPlayer is "playing", then I can hear the response, but without this trick it stays playing but mute. In parallel I have now requested com.apple.developer.carplay-voice-based-conversation entitlement , but I don't even know if when approved I will be able to use 2 entitlement for the same CarPlay app. Long story short: 1 - Should an app be able to play audio responses when it's CarPlay entitlement is com.apple.developer.carplay-driving-task? 2 - If not, can I combine entitlements com.apple.developer.carplay-driving-task and com.apple.developer.carplay-voice-based-conversation?

I am building an app that uses system audio capture. This works well for 2-channel sound cards, but as soon as the interface has more than 2 outputs, the capture volume is very low. Does anyone have tips on where to look? Capturing neither before nor after the mix doesn't solve it.

Hi, I'm currently experiencing issues with HLS streams created by FFmpeg running on Safari. When I pass the stream to the mediastreamvalidator tool and then run hlsreport on the output, I get a critical error reported: Media Entry discontinuity value does not match previous playlist for MEDIA-SEQUENCE 1 If I let the stream finish (it's a live stream from an IoT device) and then perform the stream validation again I no longer receive the critical error. My assumption is that this critical error is contributing to the HLS stall on iOS. I have also noticed that if I let the stream continue and then re-load the video control in Safari the stream starts Is there a resource with explanations or remediation paths relevant to the possible output of the hlsreport? My m3u8 output looks like this (I have redacted the server host) #EXTM3U #EXT-X-VERSION:6 #EXT-X-TARGETDURATION:2 #EXT-X-MEDIA-SEQUENCE:1 #EXT-X-PLAYLIST-TYPE:EVENT #EXT-X-INDEPENDENT-SEGMENTS #EXT-X-DISCONTINUITY #EXTINF:2.000000, https://redacted.com/segment-00001.ts #EXTINF:2.000011, https://redacted.com/segment-00002.ts #EXTINF:2.000011, https://redacted.com/segment-00003.ts #EXTINF:2.000011, https://redacted.com/segment-00004.ts #EXTINF:2.000011, #EXT-X-ENDLIST Thanks for any advice or guidance possible - if I can provide isolated code snippets I will do.

Hi, I understand that AVPlayer/AVFoundation doesn’t natively play MPEG-DASH manifests (.mpd) today, while HLS is supported and widely documented by Apple. I’m not asking for roadmap commitments, but I’d like to understand whether there is any publicly documented rationale for not supporting DASH/MPD in AVFoundation (e.g., technical constraints, platform integration, DRM ecosystem, power/performance considerations, etc.). Questions: Is there any Apple statement / documentation explaining why DASH (MPD) isn’t supported in AVFoundation? Is Apple’s recommended approach still “provide HLS for Apple clients” (potentially sharing CMAF segments and generating separate manifests)? If there’s no public rationale, is filing Feedback Assistant the best channel for requesting MPD playback support? Thanks!

I am attempting to write an app which captures the flight of a ball from the iPhone's video preview, but I need some help. I am using the following code: request = VNDetectTrajectoriesRequest(frameAnalysisSpacing: frameCnt, trajectoryLength: trajLength, completionHandler: completionHandler)` to initiate a request to capture a "ball" from a videoPreview. In the "completionHandler" I use: guard let observations = request.results as? [VNTrajectoryObservation] else { //print("observations not set up#######") return } to capture observations. In the video capture setup I am using captureSession!.sessionPreset = .hd1920x1080 In the AVCaptureVideoDataOutputSampleBufferDelegate, I am using trajectoryQueue.async { [self] in do { try sequenceHandler.perform([request], on: sampleBuffer, orientation: .right) } catch { print("VNSequenceRequestHandler perform error: \(error)") } } I have also tried using VNImageRequestHandler to "capture" observations in the Delegate. A ball is "seen" only if the "ball" is rolling on the ground. If the ball in "flying" or "bouncing" no "observations" are provided. I have tried different FrameCounts & trajectory lengths with no effect. I am now developing the app primarily using an iPhone 14Pro running iOS 26.3.1. It should be noted that I started development using an old iPhone 6plus running iOS 15.7 with captureSession!.sessionPreset = .vga640x480. and I did get some good results. If I try the VGA resolution on the iPhone 14pro, I still see no ball flight. The basis for my app is software from 5 years ago, so I'm hoping that there has been some development on ball tracking since then. Thanks in advance for any help/suggestions.

Whilst AVCaptureSession is setup to capture ProRes RAW video, is it possible to get video pixel data which can read and processed, such as using CIImage(cvPixelBuffer: ) AVCaptureVideoDataOutput outputs ProRes RAW in kCVPixelFormatType_96VersatileBayerPacked12 pixel format. Is there a provided way to debayer this pixel format into something more usable?

Hi everyone, I am working on an app that supports offline playback with FairPlay Streaming (FPS). I have successfully implemented the logic to download and persist the content keys (TLLV), and offline playback is working correctly using the stored persistent keys. However, I am now trying to implement a manual renewal process for these licenses, and I’ve run into an issue where the delegate methods are not being fired as expected. The Issue: I am calling contentKeySession.addContentKeyRecipient(asset) to force a renewal or re-fetch of the content key for a specific asset. Even though the asset is correctly initialized and the session is active, the AVContentKeySessionDelegate methods (specifically contentKeySession(_:didProvide:)) are not being triggered at all. My Questions: Why is the delegate not firing when adding the recipient? Is there a specific state or property the AVURLAsset needs to have (or a specific way it should be initialized) to trigger a new key request via addContentKeyRecipient? Is it possible to perform a manual license renewal triggered by a UI action (e.g., a button tap) without actually initiating playback of the asset? The goal is to allow users to refresh their licenses manually while online, ensuring the content remains playable offline before the previous license expires, all without forcing the user to start the video. Any insights or best practices for this manual renewal flow would be greatly appreciated.

My app has been using the iTunes Search API (itunes.apple.com/search) for a few years now, but at some point over the last week or so (late Sept. 2025) it is no longer returning track results with explicit content, regardless of whether I provide "explicit=Yes" (which is the default anyway, according to the API documentation - https://performance-partners.apple.com/search-api). Has anyone else experienced this with this API and have you figured out a workaround? FYI, I do also use the more robust Apple Music API in another part of my app, which isn't going through this issue, so I know it's technically an alternative. I just need to stick with iTunes Search API in this particular case. Thanks.

I want to clarify iPadOS AVFoundation behavior for external UVC cameras. Specifically: • Does iPadOS support external UVC controls beyond resolution and frame rate? • Or is support effectively limited to those two in practice (for non-Apple external UVC cameras)? • If other controls are supported (exposure, focus, white balance, zoom, etc.), what is the expected criteria for them to appear via AVCapture​Device? Runtime capability output from our external UVC camera: === Capabilities for VCI-AR0822-C === DeviceType: AVCaptureDeviceTypeExternal, position: 0, external: true UniqueID: 00000000-0020-0000-3407-000008220000 Active format media subtype: 420v Exposure modes supported: none Current exposure mode: locked Manual exposure (.custom) available: false Current exposure duration: nan s Current ISO: 0.0 Exposure target bias supported range: -8.0 ... 8.0 Current exposure target bias: 0.0 Focus modes supported: none Current focus mode: locked White balance modes supported: none Current white balance mode: locked Torch available: false, torch mode: 0, torch active: false Format[0]: 640x480, PF: 420v FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[1]: 640x480, PF: 420f FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[2]: 1280x720, PF: 420v FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[3]: 1280x720, PF: 420f FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[4]: 1920x1080, PF: 420v <-- ACTIVE FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[5]: 1920x1080, PF: 420f FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[6]: 2560x1440, PF: 420v FPS Range: 15.0 - 30.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[7]: 2560x1440, PF: 420f FPS Range: 30.0 - 60.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[8]: 3840x2160, PF: 420v FPS Range: 8.0 - 15.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s Format[9]: 3840x2160, PF: 420f FPS Range: 15.0 - 30.0 ISO Range: 0.0 - 0.0 Exposure duration range: 0.0 - 0.0 s =============================== We are looking for general platform guidance (not only device-specific debugging), especially whether external UVC control support on iPadOS is expected beyond resolution/fps and how to interpret “none/0.0” capability outputs. Thank you.

I have a keyboard in my iOS Morse Code app that has always been able to play audio via AVAudioEngine. Recently it has been failing to produce audio. I see that startAndReturnError: is now failing with this error: Error Domain=com.apple.coreaudio.avfaudio Code=268435459 "(null)" UserInfo={failed call=err = PerformCommand(*outputNode, kAUInitialize, NULL, 0)} What's going on? Have keyboards lost the ability to play audio? Here's how I set things up: _engine = [AVAudioEngine new]; _prefs = [[NSUserDefaults alloc] initWithSuiteName:kSharedAppGroupID]; AVAudioMixerNode* mainMixerNode = _engine.mainMixerNode; AVAudioOutputNode* outputNode = _engine.outputNode; AVAudioFormat* format = [outputNode inputFormatForBus:0]; AVAudioFormat* inputFormat = [[AVAudioFormat alloc] initWithCommonFormat:AVAudioPCMFormatFloat32 sampleRate:44100 channels:1 interleaved:NO]; self.srcNode = [[AVAudioSourceNode alloc] initWithRenderBlock:^OSStatus(BOOL* _Nonnull isSilence, const AudioTimeStamp* _Nonnull timestamp, AVAudioFrameCount frameCount, AudioBufferList* _Nonnull outputData) { // This block builds the data, but is never called, so it is not the culprit. }]; [_engine attachNode:self.srcNode]; [_engine connect:self.srcNode to:mainMixerNode format:inputFormat]; [_engine connect:mainMixerNode to:_engine.outputNode format:nil]; [_engine prepare];

Recently I received multiple user email supports because the app cannot save video to photos, they are all on iOS 26.x The code in my app around recording video and saving to Photos hasn't changed in years. I'm not able to reproduce it locally, I tried on all my available devices. In recently published build I added additional logs and it appears that all of cases that fail with 3302 have the photos access set to "Limited Access". It never happens to users with "Full Access". In that build I also added a fallback, when saving to photos fails, the app saves to Documents and it seems it works (two of my users affected users confirmed it), but it's very unfortunate. I think it kind of proves that videos aren't broken given that users are able to play them just fine. On of users says that for him saving to Photos works for 2-3 times after he reinstalls the app and then it stops working. Did anything recently changed in how we should save videos to photos? I'm using the following code. I can see in git blame that I haven't changed in since 2020 and never encountered those errors in development or heard about those issues until around 1 month ago. Thank you. PHPhotoLibrary.shared().performChanges { PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: fileURL) } completionHandler: { success, error in

Hi, I’ve identified a discrepancy between the FairPlay Streaming SPC v3 documentation and the provided Swift reference implementation regarding the SPC payload length field. Documentation states: The SPC V3 structure defines: SPC payload length: 4 bytes However, in Apple’s Swift sample implementation: // Move local offset by 12 to adjust for padding localOffset += 12 spcContainer.spcDataSize = Int(try readBigEndianU32(spc, localOffset)) This indicates: A 16-byte field (12 bytes padding + 4-byte length) This behavior also matches the SPC sample provided in the FairPlay Streaming SDK (sample_spc_v3.b64 ). 00000003 // spc version 00000000 // reserved .... 00000000000000000000000000000f40 // spc payload length (16 bytes) Could you please confirm the correct implementation? Thanks

Hi, I received an SPC without a device Identity TLLV and with an invalid (i.e a value that is not specified in the FairPlay programming guide) value of device type in the Device info TLLV. The info I got is the following - Apple Device Type: Type:0x555ea482e2ef0a7c, OS version:189.121.178 Does anyone know what device type it is, and why it does not conform to the Apple spec? Also, should I accept such an SPC or is it not valid? Thanks.

Hello together, is there an API or a way to react to AirPods Gestures for an Recording that got started from an Intent or even when the App is open? Scenario: I am walking, riding the bike or do some other mainly hands free activities or can't reach my phone but have my AirPods in my ears. Goal: Via Siri, I am able to start an AudioRecordingIntent and it runs smoothly. I'd like Pause / Resume the recording by Single Tapping the AirPods or to end the Recording by simply double-tapping. Pretty much like if I would mute/unmute or hang up on a call. MPRemoteCommandCenter doesn't seem to be the solution for this. Not sure if this is because the Recording is started through an AudioRecordingIntent.

Hello everyone, I'm working on a project where having the BPM or tempo for a song is a business requirement. I can't seem to find this data on the Song object in the Apple Music API. Is this information available via the API and I'm just not finding it in the documentation? If it isn't available, how would I go about requesting it to be added? Thanks!

Radio stations are currently not supported by the MusicKit SDK for Android. The SDK has not been updated for years now. It lacks pretty big features of Apple Music

Hello everyone, I have a question regarding the Ultra-Low Latency Frame Interpolation and Super Resolution features introduced in WWDC 2025 Session 300 (https://developer.apple.com/videos/play/wwdc2025/300/). In the video, it was mentioned that these features run on any device as long as it has iOS 26.0 or later and an Apple Silicon chipset. Based on the official support guide (https://support.apple.com/ko-kr/guide/iphone/iphe3fa5df43/ios), the iPhone 11 and iPhone SE (2nd generation) are listed as supported devices. I just want to double-check and confirm: since they meet the criteria mentioned in the video, do these features actually run without any performance issues or limitations on the iPhone 11 and iPhone SE (2nd gen)? I want to make sure I understand the exact hardware capabilities before proceeding with development. Thanks for your help!

I am working on a CarPlay app that plays back audio content. When attempting to use the CPNowPlayingPlaybackRateButton button, it works well for changing the speed, except for when the audio is paused. Then it shows the speed as 0x, which is technically true but not great for the UI. In looking at how other audio apps handle this, in the case where the app is using the CPNowPlayingPlaybackRateButton and not an image button, they mostly hide the button when paused. The only apps that don't (that I've found) are Apple's Podcasts and Audiobooks apps, which manage to keep the rate button showing the value it had when playing. So, it's possible? I tried setting the defaultRate property of the AVPlayer, along with the rate property, but that didn't seem to help. I'd like to use the standard button instead of an image button if possible. Any suggestions most welcomed!

My MusicKit developer token returns 401 (empty body) on every Apple Music API catalog endpoint. I've tried two different keys — both fail identically. Setup: Team ID: K79RSBVM9G Key ID: URNQV5UDGB (MusicKit enabled, associated with Media ID media.audio.explore.musickit) Apple Developer Program License Agreement accepted April 14, 2026 Token format (matches docs exactly): Header: {"alg":"ES256","kid":"URNQV5UDGB"} Payload: {"iss":"K79RSBVM9G","iat":,"exp":<now+15777000>} What works: /v1/storefronts/us returns 200 What fails: Every catalog endpoint returns 401 with empty body: /v1/catalog/us/search?types=artists&term=test /v1/catalog/us/artists/5920832 /v1/catalog/us/genres /v1/test The token self-verifies (signature is valid). I've tried with and without typ:"JWT", with the origin claim, and with a manually signed JWT bypassing the jsonwebtoken library. Same 401 every time. What am I missing?

Hello, Looking for guidance from Apple engineers or developers who have used Push to Talk in production I am developing an iOS application called Companion AI / Theo Voice, designed for elderly users. The goal of the app is to provide a simple, voice-first interactive assistant that enables: natural voice interaction (no typing required) daily assistance (reminders, well-being, conversation) bidirectional voice communication (the user can immediately respond by voice) ⸻ How it works The app operates in two main modes: Conversation mode the user opens the app the assistant speaks the user replies naturally by voice Proactive mode in specific useful situations (e.g. medication reminders, check-ins) the app initiates a voice interaction the user can respond immediately ⸻ Important constraints there is no continuous listening the microphone is only active during interactions users can disable proactive interactions frequency is limited and user-controlled ⸻ Question We are considering using the Push to Talk framework in order to: allow the app to be awakened in the background initiate a voice interaction enable immediate voice response from the user Would this usage be considered aligned with the intended use of Push to Talk? Are there any specific recommendations to ensure compliance with App Store Review Guidelines? Thank you very much for your guidance.
