# resume(with:) Resume the task that’s awaiting the continuation by returning or throwing the given result value. ``` func resume(with result: sending Result) where E == any Error, Er : Error ``` ## Parameters `result` The result. If it contains a `.success` value, the continuation returns that value; otherwise, it throws the `.error` value. ## Discussion A continuation must be resumed exactly once. If the continuation has already resumed, then calling this method results in undefined behavior. After calling this method, control immediately returns to the caller. The task continues executing when its executor schedules it. --- Copyright © 2026 Apple Inc.
