# nextResponder

The next responder after this one, or `nil` if it has none.

```
unowned(unsafe) var nextResponder: NSResponder? { get set }
```

## Discussion

The next responder must be an object that inherits, directly or indirectly, from `NSResponder`.

[`noResponder(for:)`](/documentation/AppKit/NSResponder/noResponder(for:))

Handles the case where an event or action message falls off the end of the responder chain.
