Great !!! 👌 Now add the following code to your viewController. you can add this in viewDidLoad or any clickable @IBAction .

let scanner = QRCodeScannerController(cameraImage: UIImage(named: "ImageIcon40"),
cancelImage: UIImage(named: "cancel"), flashOnImage: UIImage(named: "Flash40"),
flashOffImage: UIImage(named: "Flash40"))

scanner.delegate = self
scanner.mode = .camera
self.present(scanner, animated: true, completion: nil)

Also add this extension to your view controller. here you will get the output from scanner

extension ViewController: QRScannerCodeDelegate {
    func qrScanner(_ controller: UIViewController, scanDidComplete result: String) {
        print("result:\(result)")
    }
    
    func qrScannerDidFail(_ controller: UIViewController, error: String) {
        print("error:\(error)")
    }
    
    func qrScannerDidCancel(_ controller: UIViewController) {
        print("SwiftQRScanner did cancel")
    }
}

To Customise View

to change the size/color of white square shape edit SquareView.swift
to add any button/image/view or modify check SwiftQRScannerUIView.swift.
to change animation check LBXScanLineAnimation.swift .

UIColorExtension.swift is used to convert hex string into UIColor.

Example: to add white color in text

let label = UILabel()
label.textColor = UIColor.colorFrom(hexString: "FFFFFF")
