📸 Detect barcodes like QR in Xcode's Simulator ✨

@rocketsim.app Camera Simulation supports capturing metadata 🚀

If you're using AVCaptureMetadata or Vision to detect codes, you'll easily be twice as fast during development. In fact, this might be the only way to test your app using the Simulator!
