# CHHapticEngine.StoppedReason.idleTimeout

The engine shut down because you’ve enabled automatic shutdown, and the engine reached its idle timeout.

## Declaration

```swift
case idleTimeout
```

## Discussion

Discussion If there’s a time-critical pattern to play, restart the engine. Otherwise, do nothing and the engine will automatically restart when the next pattern plays. note: Delegating engine restart to the system can add a slight delay to the start of the pattern.
