# CHHapticEngine.StoppedHandler

A typealias for the block that the haptic engine calls after it stops due to an external cause.

## Declaration

```swift
typealias StoppedHandler = (CHHapticEngine.StoppedReason) -> Void
```

## Discussion

Discussion The system calls the stopped handler for when it’s stopped by an external event like an audio session interruption or an auto-shutdown. note: The stopped handler isn’t called if you explicitly stop the engine by calling the stop(completionHandler:) method.
