We don't need to be super thorough about this, as we can assume Apple have done testing of their implementations themselves. However, we need to find out which API performs best in general out of the following:
CIDetector
AVCaptureMetadataOutput as mentioned by @D-Link13 in #3
Any others? We could possibly check OpenCV if neither of the above are satisfactory, but that's a big dependency to include if the SDK already provides a good enough solution.
It's also possible both of these implementations are backed by the same algorithm, so performance might be identical. It would be interesting to find out!
