Hi!

I'm trying to open the barcode scanner from class "Partynallen" with a button placed in "NewViewController". I can get the barcode to open and scan stuff, but the image freezes and no result is being passed. What could i possibly be doing wrong?

Appreciate any help provided, thanks in advance.

import QRCodeReader
import Alamofire
class Partynallen: UIViewController, QRCodeReaderViewControllerDelegate {
    lazy var readerVC: QRCodeReaderViewController = {
    let builder = QRCodeReaderViewControllerBuilder {
    //change object to scan and the initial position of the camera
        $0.reader = QRCodeReader(metadataObjectTypes: [.qr, .ean13], captureDevicePosition: .back)
    // Configure the view controller (optional)
    $0.showTorchButton = true
    $0.showSwitchCameraButton = false
    $0.showCancelButton = true
    $0.showOverlayView = true //shows the square area of the QRCode Scanner
        $0.rectOfInterest = CGRect(x: 0, y: 0, width: 1, height: 1)
    }
    return QRCodeReaderViewController(builder: builder)
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        readerVC.delegate = self
    }

    func reader(_ reader: QRCodeReaderViewController, didScanResult result: QRCodeReaderResult) {
    //code to be added
        reader.stopScanning()
        //print(result)
        //print(result.value)
        //barcode = result.value
       //Apifetch(code: "URL")
        dismiss(animated: true, completion: nil)
    }
    func readerDidCancel(_ reader: QRCodeReaderViewController) {
    //code to be added
        reader.stopScanning()
        dismiss(animated: true, completion: nil)
    }

}
class NewViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        Partynallen().readerVC.delegate = Partynallen().self // DONT KNOW IF THIS IS CORRECT?
    }
        @IBAction func scan(_ sender: UIButton) {
            Partynallen().readerVC.modalPresentationStyle = .formSheet
            present(Partynallen().readerVC, animated: true)
    }

}
