# navigationItem

Represents the search display controller in a navigation controller’s navigation bar.

```
var navigationItem: UINavigationItem? { get }
```

## Discussion

You can configure the navigation item as described in the [`UINavigationItem`](/documentation/UIKit/UINavigationItem), with the exception of configuring the title view.

> Important:
> The system raises an exception if you attempt to set the ``doc://com.apple.uikit/documentation/UIKit/UINavigationItem/titleView`` property for a search display controller’s navigation item.
