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) 		} 		 		 }
