I'm getting interested in using QR codes to pair devices or quickly share information (i.e. one device displays a QR code that the other device then reads with its camera.)
It's quite easy to generate a QR code using CoreImage. The roadblock I've hit is that AVFoundation only supports QR-code scanning on iOS, not Mac OS. (I.e. AVCaptureMetadataOutput is an iOS-only class.) That's a roadblock for transferring data (like a private key) from an iOS device to a Mac.
I've searched a bit for a Mac-compatible QR scanning library, but found nothing on Github or CocoaControls. Anyone know of one? (I know there are cross-platform libraries to do the raw image analysis, but I'm hoping to find something that (a) builds in Xcode, and (b) includes the code to talk to the camera since I know nothing about doing that.)
