Haptic feedback with RIO unit

Question

If I have AVAudioSession configured with .playAndRecord category and a remote IO unit running, what's the besy way to enable haptic feedback on button presses?

Answer 1

You can use UIFeedbackGenerator to create haptic feedback in your iOS app. You can use one of the below options depends on your requirement:

UIImpactFeedbackGenerator: Use impact feedback generators to indicate that an impact has occurred. For example, you might trigger impact feedback when a user interface object collides with something or snaps into place.

Example:

let impact = UIImpactFeedbackGenerator()
impact.impactOccurred()

UISelectionFeedbackGenerator. Use selection feedback generators to indicate a change in selection.

Example:

let impact = UISelectionFeedbackGenerator()
impact.selectionChanged()

UINotificationFeedbackGenerator. Use notification feedback generators to indicate successes, failures, and warnings.

Example:

let impact = UINotificationFeedbackGenerator()
impact.notificationOccurred(.success)
