Pause Assistive Technology - VoiceOver

I'm trying to call for a pause to VoiceOver technology:

UIAccessibility.post(notification: .pauseAssistiveTechnology, argument: UIAccessibility.AssistiveTechnologyIdentifier.notificationVoiceOver)

The error is:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'You must pass the identifier of the assistive technology to pause.  See UIAccessibilityConstants.h for the list of valid values.

I see that notificationVoiceOver is an identifier.

Any suggestions? Do I need to init an identifier with a rawValue?

Thanks for any help!

You can't, even if the pauseAssistiveTechnology type property seems to be appropriate for this purpose at first sight.😨

Indeed, VoiceOver can't be paused because the system needs to take over when need be... which means during the pause you impose as well and a pause means nothing anymore in this context.

A good candidate for this kind of pause is the Switch Control feature as explained in this discussion of the Apple documentation.
