Issue: In iOS 26 (tested on Developer Beta), AVCaptureMetadataOutputObjectsDelegate no longer receives callbacks when using .face detection. metadataOutput.metadataObjectTypes = [.face]

I have an app that edits photos in your library. When I call try CIContext().writeHEIFRepresentation(of: editedImage, to: fileURL, format: .RGBA8, colorSpace: originalImage.colorSpace!) The following is logged to the console: writeImageAtIndex:1012: ⭕️ ERROR: 'App' is trying to save an opaque image (5712x4284) with 'AlphaLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. What does that mean and how can I resolve it? Xcode Version 16.0 (16A242d) iOS 18.1 (22B82)

Opening this question after discussing the issue in the AVCapture lab, hopefully so we can track down this issue. We've been noticing some crashes in App Store Connect caused by layoutSublayers being called on a background thread. After debugging the issue a bit we found that all calls which modified the AVCaptureSession or preview layer were indeed done on the main thread. It would be useful to see what results in AVCaptureVideoPreviewLayer.updateFormatDescription being called. I've attached the crashlog below.

We observed that the PHPicker is unable to load RAW images captured on an iPhone in some scenarios. And it is also somehow related to iCloud. Here is the setup: The PHPickerViewController is configured with preferredAssetRepresentationMode = .current to avoid transcoding. The image is loaded from the item provider like this: if itemProvider.hasItemConformingToTypeIdentifier(kUTTypeImage) { itemProvider.loadFileRepresentation(forTypeIdentifier: kUTTypeImage) { url, error in // work } } This usually works, also for RAW images. However, when trying to load a RAW image that has just been captured with the iPhone, the loading fails with the following errors on the console: [claims] 43A5D3B2-84CD-488D-B9E4-19F9ED5F39EB grantAccessClaim reply is an error: Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application."

We think it is related to iCloud Photos: On the device that has iCloud Photos sync enabled, the picker is able to load the image right after it was synced to the cloud. On devices that don't sync the image, loading always fails. It seems that the sync process is doing some processing (?) of the image that will later enable the picker to load it successfully, but that's just guessing. Additional observations: This seems to only occur for images that were taken with the stock Camera app. When using Halide to capture RAW (either ProRAW or RAW), the Picker is able to load the image. When trying to load the image as kUTTypeRawImage instead of kUTTypeImage, it also fails. The picker also can't load RAW images that were AirDroped from another device, unless it synced to iCloud first. This is reproducable using the Selecting Photos and Videos in iOS sample code project. We observed this happening in other apps that use the PHPicker, not just ours. Is this a bug, or is there something that we are missing?

In the latest production release of our iOS app (deployed via the App Store), we’ve observed a significant increase in AVCaptureSessionWasInterrupted notifications where the interruption reason has a rawValue of 4. The session does not automatically recover, even after returning from background or deleting/reinstalling the app. An employee ran into this and was able to get a recording. We see the below error when attempting to take photos. "Error Domain=AVFoundationErrorDomain Code=-11803 \"Cannot Record\" UserInfo={AVErrorRecordingFailureDomainKey=3, NSLocalizedDescription=Cannot Record, NSLocalizedRecoverySuggestion=Try recording again.}", } This interruption causes the camera preview to remain black, and any attempt to capture an image results in a failure with the following error: Some questions from our team: What common system conditions or foreground app behaviors can cause .videoDeviceNotAvailableWithMultipleForegroundApps (reason 4) to become persistent? Our teams under is under the impression the interruption reason 4 is mostly associated with iPad and PiP, but neither of these are true in the logs we see. Is manual recovery of the session required? Is there a recommended strategy to detect that the session is unrecoverable and gracefully notify the user or rebuild the session? Is there an instrument(s) in XCode you would recommend when trying to evaluate the increase in reason 4? Best, Ben
