@omz I hadn't! Exactly what I was looking for. I'm interested in trying to use QR codes for indoor navigation and I thought pythonista would be a great platform for demonstrating this. I'll come back and share when I have some results.
@omz I'm attempting to use your example to make a qr code reader. I'm hung up on how to make the dispatch queue work with the AVCaptureMetadataOutputObjectsDelegate. Any help would be greatly appreciated.
