To use more features like camera switch, flash and many other options use QRScannerConfiguration:

configuration.cameraImage = UIImage(named: "camera")

And finally implement delegate methods to get result:

func qrScanner(_ controller: UIViewController, scanDidComplete result: String) {
    print("result:\(result)")
}

func qrScannerDidFail(_ controller: UIViewController, error: QRCodeError) {
    print("error:\(error.localizedDescription)")
}

func qrScannerDidCancel(_ controller: UIViewController) {
    print("SwiftQRScanner did cancel")
}
