In iOS 26 (Developer Beta), the AVCaptureMetadataOutputObjectsDelegate no longer receives callbacks when metadataOutput.metadataObjectTypes = [.face] is set. On earlier iOS versions the issue does not occur. Interestingly, face detection works if I set the sessionPreset to .medium, but not with .high — except on the iPhone 16 Pro Max, where it works regardless.

Hello @Chavd,

This sounds like a regression, please file a bug report for this issue if you have not done so already using Feedback Assistant.

Having said that, I've been unable to reproduce the behavior you described, so I'd be curious to see a focused sample with steps to reproduce.
