unregister(completionHandler:)

Unregisters the service so the system no longer launches it and calls a completion handler you provide with the resulting error value.

Declaration

func unregister(completionHandler handler: @escaping  @Sendable ((any Error)?) -> Void)

func unregister() async throws

Parameters

handler:
A completion handler to call with the result of the unregistration operation. Upon an unsuccessful return, the handler contains a new Nserror object describing the error. Upon successful return, this argument is NULL.

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 unregister() async throws
