# delegate

The delegate object that receives notifications coming from the push registry object.

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

## Discussion

You must assign a valid object to this property before modifying the [`desiredPushTypes`](/documentation/PushKit/PKPushRegistry/desiredPushTypes) property. A valid delegate object is required to receive push tokens and payload data from incoming pushes.

For more information about the methods of the `PKPushRegistryDelegate` protocol, see [`PKPushRegistryDelegate`](/documentation/PushKit/PKPushRegistryDelegate).
