How to Capture Text from the Camera in SwiftUI 3

To create a button for this purpose, you need a class that adopts the protocols UIResponder and UIKeyInput. The required variable hasText and method deleteBackward are not used so you can just ignore them.

class ScanTextResponder: UIResponder, UIKeyInput {
	init(title: Binding<String>) {
		_title = title
	}
