# delegate

The delegate for the session object

## Declaration

```swift
weak var delegate: (any WCSessionDelegate)? { get set }
```

## Discussion

Discussion You must assign an object conforming to the WCSessionDelegate protocol to this property before calling the activate() method. The delegate is responsible for responding to session-related changes, for processing incoming data, and for responding to errors. For more information about implementing your delegate object, see WCSessionDelegate.
