# delegate

The delegate of the WatchKit app object.

```
weak var delegate: (any WKApplicationDelegate)? { get }
```

## Discussion

The delegate object is an object that conforms to the [`WKApplicationDelegate`](/documentation/WatchKit/WKApplicationDelegate) protocol. You provide the delegate object and use it to manage lifecycle events in your extension. Providing a delegate object is required if your extension supports actionable notifications or Handoff behaviors.

For more information about the methods of the delegate object, see [`WKApplicationDelegate`](/documentation/WatchKit/WKApplicationDelegate).
