I'm building a multi-box PIN/OTP input in SwiftUI. In UIKit, I used UITextFieldDelegate to detect backspace presses on an empty field to move focus backward. SwiftUI’s .onChange(of: text) only triggers when text is actually deleted, completely missing backspaces on an already empty field. Is there a pure SwiftUI way to handle this now, or are we still forced to wrap UITextField via UIViewRepresentable?

When scanning a FIDO QR code within an iOS app—whether using a custom AVFoundation (AVCaptureSession) implementation or DataScannerViewController—the system displays a native OS confirmation prompt. However, scanning the same QR code using the native system Code Scanner bypasses this prompt entirely. As a developer: Is there a way to suppress or avoid this native prompt when using custom in-app scanners? Alternatively, can I programmatically invoke the system Code Scanner directly from my app and have it deep-link back to the app once the scan is complete?
