# WKExtensionDelegateClassName

The name of your watchOS app’s extension delegate.

## Discussion

Discussion This key provides the name of a class that adopts the WKExtensionDelegate protocol. Xcode automatically includes this key in the WatchKit extension’s information property list when you create a watchOS project from a template. You only modify this value when you rename or replace the extension delegate.
