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!

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