Прочтите VCFCard с QR-кода?

Question

Я хочу спросить, если это возможно, чтобы прочитать VCF карту как данные CNContact как GivenName, FamilyName ...

Это моя функция вывода QR Code Scanner

func captureOutput(_ captureOutput: AVCaptureOutput!, didOutputMetadataObjects metadataObjects: [Any]!, from connection: AVCaptureConnection!) { 

    if metadataObjects == nil || metadataObjects.count == 0 { 
     qrCodeFrameView?.frame = CGRect.zero 
     messageLabel.text = "No QR/barcode is detected" 
     return 
    } 


    let metadataObj = metadataObjects[0] as! AVMetadataMachineReadableCodeObject 

    if supportedCodeTypes.contains(metadataObj.type) { 
     let barCodeObject = videoPreviewLayer?.transformedMetadataObject(for: metadataObj) 
     qrCodeFrameView?.frame = barCodeObject!.bounds 

     if metadataObj.stringValue != nil { 
      messageLabel.text = metadataObj.stringValue 
     } 
    } 
}

я не могу проверить с QR-код, но это будет какая-то помощь:

 if 
      let metadataString = metadataObj.stringValue, 
      let data = metadataString.data(using: .utf8) 
     { 
      do { 
       let contacts = try CNContactVCardSerialization.contacts(with: data) 
       print(contacts) 
       //Use `contacts` as you like 
       if let contact = contacts.first { 
        print(contact.givenName) 
        //... 
       } 
       //... 
      } catch { 
       //Unreadable as CNContact 
       print(error) 
       //... 
      } 
     } else { 
      //May never happen... 
     }
