# serviceExtensionWillTerminate()

Notifies your app extension that the system is about to terminate the extension because it’s taking too long to complete its task.

## Declaration

```swift
optional func serviceExtensionWillTerminate()
```

## Discussion

Discussion If your didReceiveLocationPushPayload(_:completion:) method takes too long to collect a location and call its completion block, the system calls this method on the main thread. Use this method to execute the completion block from didReceiveLocationPushPayload(_:completion:) as quickly as possible.
