## Discussion

Discussion 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. important: This method is available in iOS 12.5, and in iOS 13.5 and later.
