I've added facingPosition as an extension on AVCaptureDevice so please take a look there (if you haven't already) 🙂

I think it's too restrictive tho if deviceType == .builtInWideAngleCamera - it does not handle external cams. We can remove this part instead.

Hm, but it comes at the cost of filtering out built-in camera. Are we sure we don't wanna handle all 3 positions instead?
