To be precise, the barcode recognition range is only in the middle of the screen, and the QR code is not affected.

I also encountered the same problem, on iOS16, it seems that the QR code cannot be set at the same time as the barcode.
//
self.output.metadataObjectTypes=@[AVMetadataObjectTypeQRCode,
AVMetadataObjectTypeEAN13Code,
AVMetadataObjectTypeEAN8Code,
AVMetadataObjectTypeUPCECode,
AVMetadataObjectTypeCode39Code,
AVMetadataObjectTypeCode39Mod43Code,
AVMetadataObjectTypeCode93Code,
AVMetadataObjectTypeCode128Code,
AVMetadataObjectTypePDF417Code,
AVMetadataObjectTypeDataMatrixCode];
// Before iOS15, I set it like this and it worked fine. After iOS16, it fails.
I removed, AVMetadataObjectTypeQRCode AVMetadataObjectTypeDataMatrixCode, it can correctly identify the barcode.
But before iOS15, QR code and barcode are used at the same time, this is a bug of iOS16 system, I hope to get professional answers from Apple developers, thank you!
