certain QR codes are not readable?
I have done code for reading QR code but it sometimes does not read certain types of QR code. IOS and google chrome is able to read codes no matter how they are, how to get the same kind of functionality... output.setMetadataObjectsDelegate(self, queue: DispatchQueue.main)  output.metadataObjectTypes = [ 	 AVMetadataObject.ObjectType.qr,			 	 AVMetadataObject.ObjectType.dataMatrix ] code that I used for reading QR code as follows class ViewController: UIViewController, AVCaptureMetadataOutputObjectsDelegate {     var video = AVCaptureVideoPreviewLayer()               override func viewDidLoad() {         super.viewDidLoad()         // Do any additional setup after loading the view.                  //create session         let session = AVCaptureSession()                  //Define capture device         let captureDevice = AVCaptureDevice.default(for: AVMediaType.video)                  do         {             let input = try AVCaptureDeviceInput(device: captureDevice!)             session.addInput(input)         }         catch         {             print("ERROR")         }                  let output = AVCaptureMetadataOutput()         session.addOutput(output)                  output.setMetadataObjectsDelegate(self, queue: DispatchQueue.main)                  output.metadataObjectTypes = [AVMetadataObject.ObjectType.qr, AVMetadataObject.ObjectType.dataMatrix]                  video = AVCaptureVideoPreviewLayer(session: session)         video.frame = view.layer.bounds         view.layer.addSublayer(video)                  session.startRunning()     }          func metadataOutput(_ output: AVCaptureMetadataOutput, didOutput metadataObjects: [AVMetadataObject], from connection: AVCaptureConnection) {                  if metadataObjects != nil && metadataObjects.count != nil {                          if let object = metadataObjects.first as? AVMetadataMachineReadableCodeObject { //            if let object = metadataObjects[0] as? AVMetadataMachineReadableCodeObject {                 if object.type == AVMetadataObject.ObjectType.qr {                     let alert = UIAlertController(title: "QR code", message: object.stringValue, preferredStyle: UIAlertController.Style.alert)                     alert.addAction(UIAlertAction(title: "Retake", style: UIAlertAction.Style.default, handler: nil))                     alert.addAction(UIAlertAction(title: "Copy", style: UIAlertAction.Style.default, handler: { (nil) in                         UIPasteboard.general.string = object.stringValue                     }))                                          self.present(alert, animated: true, completion: nil)                 }             }         }              } }
