The very first thing we need to do is make sure that this array is not nil, and it contains at least one object. metadataObjects) of the method is an array object, which contains all the metadata objects that have been read.

Insert the code below in the do-catch block: The preview layer is added as a sublayer of the current view. You use this preview layer in conjunction with an AV capture session to display video. This can be done using an AVCaptureVideoPreviewLayer, which actually is a CALayer. Now that we have set and configured an AVCaptureMetadataOutput object, we need to display the video captured by the device’s camera on screen. The metadataObjectTypes property is also quite important as this is the point where we tell the app what kind of metadata we are interested in.

So, we use DispatchQueue.main to get the default serial queue. According to Apple’s documentation, the queue must be a serial queue. A dispatch queue can be either serial or concurrent. In the above code, we specify the dispatch queue on which to execute the delegate’s methods. When new metadata objects are captured, they are forwarded to the delegate object for further processing. For now, continue to add the following lines of code in the do block of the viewDidLoad method:ĬaptureMetadataOutput. This class, in combination with the AVCaptureMetadataOutputObjectsDelegate protocol, is used to intercept any metadata found in the input device (the QR code captured by the device’s camera) and translate it to a human-readable format.ĭon’t worry if something sounds weird or if you don’t totally understand it right now – everything will become clear in a while. The AVCaptureMetaDataOutput class is the core part of QR code reading. In this case, the output of the session is set to an AVCaptureMetaDataOutput object. The AVCaptureSession object is used to coordinate the flow of data from the video input device to our output. To perform a real-time capture, we use the AVCaptureSession object and add the input of the video capture device. In the code above, we specify to retrieve the device that supports the media type. If the issue persists, contact MDM Support with the logs.Assuming you’ve read the previous chapter, you should know that the AVCaptureDevice.DiscoverySession class is designed to find all available capture devices matching a specific device type. You'll have to reopen the app to detect the QR code. If the QR is detected once and the user accidentally cancels the access URL, the QR code will not be detected again. The QR was is not detected more than once Check if the option is disabled, if disabled, enable it and try scanning the QR code again.Navigate to Settings -> Camera -> Scan QR code.Follow the steps given below to check if QR scanning is disabled and to enable it.QR scanning is disabled in the camera app. If QR scanning is disabled in the native camera app, the MDM QR cannot be scanned. QR scanning is disabled in the camera app.

The user can make use of third party apps to scan the QR code or update the device to the latest version. If the device's OS version is less than iOS 11 then the QR code cannot be scanned using the native app. QR scanning is supported in iOS devices from iOS 11 and above.

Resolutions The OS version of the device is not iOS 11 or above.

QR scanning is disabled in the camera app.

The OS version of the device is not iOS 11 or above.

The QR code might not be scanned due to any of the following reasons: But, you are unable to scan the QR code using the native camera app of iOS devices. User's can scan this QR code using their mobile devices and complete the enrollment process.
