Present native iOS document scanner?

Question

iOS 11 has a built in document scanner that you can launch from Notes. I’d like to scan documents for my app, is there a way to present the native document scanner and receive its images?

Nothing public. Possibly try poking at alternative values for `UIImagePickerController.CameraCaptureMode` — Warren Burton, Oct 28 '18 at 12:49
Unfortunately only `.photo` and `.video` are the available modes. — TruMan1, Oct 28 '18 at 13:42

This is now available in iOS 13+ and is provided through the VisionKit API.

Present the VNDocumentCameraViewController view controller, registering the VNDocumentCameraViewControllerDelegate delegate:

let documentCameraViewController = VNDocumentCameraViewController()
documentCameraViewController.delegate = self
present(documentCameraViewController, animated: true)

Then receive the delegate calls once a document has been successfully captured by the user:

documentCameraViewController(_ controller: VNDocumentCameraViewController, 
                       didFinishWith scan: VNDocumentCameraScan)
