I want to fully support the new iPhone models in my app, and ideally need to know the available lenses. However, I can't find information about this on the web and they're not reported in the simulators. The closest thing I found was this, but it's very out of date. https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/Cameras/Cameras.html My only other option is to buy each device, which isn't really feasible, or to log the data from real users via an analytics tool which isn't ideal either. Thanks, Alex

Hey, I'm having a very strange issue on my iPhone 17 Pro. I'm trying to capture a 12MP ProRAW image using the Telephoto Lens with the photoQualityPrioritization set to .Quality. Unfortunately I receive this error when trying to capture the image: Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x134f7a1f0 {Error Domain=NSOSStatusErrorDomain Code=-16802 "(null)"}, NSLocalizedFailureReason=An unknown error occurred (-16802), AVErrorRecordingFailureDomainKey=4, NSLocalizedDescription=The operation could not be completed} The photo captures correctly at 7.9x zoom, it's only a problem when the zoom goes over 8x. Also, it's only this particular configuration of settings which causes the issue. I'm able to capture an image if I either: Set quality to ".balanced" Set max dimensions to 48MP Capture a JPEG image instead of a ProRAW image Use the TripleCamera fusion lens Any help would be greatly appreciated.

Is there a way to destroy MIDIUMPMutableEndpoint again? In my app, the user has a setting to enable and disable MIDI 2.0. If MIDI 2.0 should not be supported (or if iOS version < 18), it creates a virtual destination and a virtual source. And if MIDI 2.0 should be enabled, it instead creates a MIDIUMPMutableEndpoint, which itself creates the virtual destination and source automatically. So here is my problem: I didn't find any way to destroy the MIDIUMPMutableEndpoint again. There is a method to disable it (setEnabled:NO), but that doesn't destroy or hide the virtual destination and source. So when the user turns MIDI 2.0 support off, I will have two virtual destinations and sources, and cannot get rid of the 2.0 ones. What is the correct way to get rid of the MIDIUMPMutableEndpoint once it is created?

I am able to capture 48mp photos using .builtInWideAngleCamera, but it seems like .builtInTripleCamera is capped at 12mp? Is there a way to capture 48mp photos using .builtInTripleCamera? Because .builtInTripleCamera provides smooth transition between cameras during zooming, and I'd like to keep this behavior. New iPhone 17 Pro have all their cameras at 48mp. Is there a chance that their .builtInTripleCamera is capable of capturing 48mp? Or is this an API limitation?

I'm experiencing an issue with my app when saving images to the camera roll. This is intermittent, but it happens several times a day.

I never saw the issue on this device. Here is an excerpt from my code for saving the image: var localIdentifier = String() PHPhotoLibrary.shared().performChanges({ let albumChangeRequest = PHAssetCollectionChangeRequest(for: album) let assetCreationRequest = PHAssetCreationRequest.forAsset() let options = PHAssetResourceCreationOptions() assetCreationRequest.addResource(with: .photo, data: imageData, options: options) assetCreationRequest.creationDate = Date.now let placeHolder = assetCreationRequest.placeholderForCreatedAsset albumChangeRequest?.addAssets([placeHolder!] as NSArray) if placeHolder != nil { localIdentifier = (placeHolder?.localIdentifier)! } }) { (didSucceed, error) in OperationQueue.main.addOperation({ didSucceed ? success(localIdentifier) : failure(error) }) } I'm not sure why this would be device specific but I have had users with iPhone 17 Pro and iPhone Air reporting the issue.

Hey there, We're seeing a high rate of 403 - Invalid Authentication on this endpoint v1/me/library/artists since a few days. Does anyone have the same issue ?

Our app plays TS files on an iPhone. The app fragments the TS files, creates an M3U8 playlist, converts them to HLS(HTTP Live Streaming), and then uses AVPlayer to play the video content. On a device running iOS 26, after starting playback and seeking, restarting playback causes the video and audio to be out of sync (by about 2-3 seconds depending on the situation). This also occurs on iPadOS/macOS 26. This issue was not observed prior to iOS 18. We are trying to fix this issue on the app side, but we have the following questions: The behavior of AVPlayer is different between iOS 26 and previous versions. Has there been any change that could be considered? Or is it a bug? We tried pausing before seeking, but it didn’t seem to have any effect. Are there any APIs or workarounds that can improve this? We would appreciate it if you could tell us any other helpful documents or URLs.

I want to use both front UW and TrueDepth cameras in iPad which has front UW camera. Firstly, I have used only front builtInDualCamera by AVFoundation and tried all the formats that can be used with builtInDualCamera, but there was no format that could capture UW. Secondly, I have tried to both front builtInDualCamera and builtInUltraWideCamera, but there was no combination that could use builtInUltraWideCamera and builtInDualCamera. Is there any way ?

I am developing an app with transcription and I am exploring ways to improve the transcription from the SpeechAnalyzer/Transcriber for technical terms. SFSpeech... recognition had the capability of being augmented by contextualStrings. Does something similar exist for SpeechAnalyzer/Transcriber? If so please point me towards the documentation and any sample code that may exist for this. If there are other options, please let me know.

I'm wondering if someone happened issues with currentPlaybackRate in released version of iOS 26.0? There is no issue happened in case of iOS 18.5. When I changed currentPlaybackRate on iOS 26.0, it seems to unexpectedly change currentPlaybackRate to be 0 or 1.0 forcibly no matter DRM or non-DRM contents. And also, playing music will be abnormal behavior and unstable with noise if currentPlaybackRate is not 1.0. And changes stop state and play state frequently.

Hi, After updating to iOS 26, our app is experiencing playback failures with AVPlayer. The same code and streams work fine on iOS 18 and earlier. Error: Domain [CoreMediaErrorDomain] Code [-15628] Description [The operation couldn’t be completed.] Underlying Error Domain [(null)] Code [0] Description [(null)] Environment: iOS version: iOS 26 Stream type: HLS (m3u8) with segment (.ts) files Observed behaviour: We don’t have concrete steps to reproduce the issue, but so far, we have observed that this error tends to occur under low network conditions.

In iOS 26 When we download any DRM content first time it is downloading again when we edit audios and Video Quality and start downloading it is freezing complete app. Neither it is crashing not giving any error.

Hello Apple Engineers, I am developing a feature related to SpeechRecognizer (import Speech), and I have two questions: After adding the NSSpeechRecognitionUsageDescription key in my Info.plist, when I initialize an SFSpeechRecognizer instance, the system shows an authorization alert. The alert contains a pre-defined message from Apple: “Speech data from this app will be sent to Apple to process your requests. This will also help Apple improve its speech recognition technology.” Is it possible to remove or customize this message? My app runs in a network environment with a whitelist. I need to know which URL the SFSpeechRecognizer instance connects to, and which port it uses, so that I can add it to the whitelist. Thank you very much for your support! Best regards, Yu Cheng

I'm receiving output from avcapturesession and capturing an image using Vision, but the image is output in landscape orientation instead of portrait. Even when I set the orientation to up in ciimage, cgimage, and uiimage, the image is still output in landscape orientation. On iPhones 16 and below, the image is output in portrait orientation. But on iPhones 17 and above, the image is output in landscape orientation. Please help.

I have some tried-and-tested code that records and plays back audio via AUHAL which breaks on Tahoe on Intel. The same code works fine on Sequioa and also works on Tahoe on Apple Silicon. To start with something simple, the following code to request access to the Microphone doesn't work as it should: bool RequestMicrophoneAccess () { __block AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType: AVMediaTypeAudio]; if (status == AVAuthorizationStatusAuthorized) return true; __block bool done = false; [AVCaptureDevice requestAccessForMediaType: AVMediaTypeAudio completionHandler: ^ (BOOL granted) { status = (granted) ? AVAuthorizationStatusAuthorized : AVAuthorizationStatusDenied; done = true; }]; while (!done) CFRunLoopRunInMode (kCFRunLoopDefaultMode, 2.0, true); return status == AVAuthorizationStatusAuthorized; } On Tahoe on Intel, the code runs to completion but granted is always returned as NO. Tellingly, the popup to ask the user to grant microphone access is never displayed, even though the app is not present in the Privacy pane and never appears there. On Apple Silicon, everything works fine. There are some other problems, but I'm hoping they have a common underlying cause and that the Apple guys can figure out what's wrong from the information in this post. I'd be happy to test any potential fix. Thanks.

I have some question about the TTS My device default language is zh-HK. (cantonese) my device is iPhone 16 Pro, IOS 18.6 I create a function speakMandarin I want the device to speak the zh-CN (putonghua) however the device only can speak zh-HK (cantonese).

Playback fails intermittently on slow/unstable networks.

Is there a recommended way on macOS 26 Tahoe to take a CoreAudio AudioObjectID and use it to lookup the underlying USB LocationID? I previously used AudioObjectID to query the corresponding DeviceUID with kAudioDevicePropertyDeviceUID. Then I queried for the IOService matching kIOAudioEngineClassName with property kIOAudioEngineGlobalUniqueIDKey matching DeviceUID, and I loaded kUSBDevicePropertyLocationID from the result. This fails on macOS 26, because the IO Registry for the device has an entry for usbaudiod rather than AppleUSBAudioEngine, and usbaudiod does not include a kIOAudioEngineGlobalUniqueIDKey property (or any other property to map it to a CoreAudio DeviceUID). My use-case here is a piece of audio recording software that allows configuring a set of supported audio devices via USB HID prior to recording. I present the user with a list of CoreAudio devices to use, but without a way to lookup the underlying USB LocationID, I cannot guarantee that the configured device matches the selected device (e.g. if the user plugged in two identical microphones).

Hi, I downloaded and ran https://developer.apple.com/documentation/realitykit/rendering-stereoscopic-video-with-realitykit and noticed that memory usage grows linearly. I replaced the sample video with a different 8k side by side video, and the app crashed almost immediately due to memory leak. it looks like the culprit is from makeMutablePixelBuffer() function and the allocated pixelBuffers are not recycled after being used. screenshot is from a physical device.

I tried to modify the AVCam sample code by copying the code here https://developer.apple.com/documentation/avfoundation/adopting-smart-framing-in-your-camera-app#Configure-the-smart-framing-monitor smart framing monitors I can ensure the activeformat supports smart framing, but the supported frames in monitor is always nil. In my another project it has supported value, but the observation has never been triggered, then I tried to keep printing the recommended frame, it's always nil. Could the engineer embed the code into AVCam rather than posting a few code pieces?
