important:

You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration:

func setExposureNotificationEnabled(_ enabled: Bool) async throws

For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.

If the user hasn’t authorized exposure notification, this method displays a user dialog requesting consent.
