# searchResultsUpdater

The object responsible for updating the contents of the search results controller.

```
weak var searchResultsUpdater: (any UISearchResultsUpdating)? { get set }
```

## Discussion

Assign an object that adopts the [`UISearchResultsUpdating`](/documentation/UIKit/UISearchResultsUpdating) protocol. Use the methods of that protocol to search your content and deliver the results to your search results view controller. The object contained by the [`searchResultsUpdater`](/documentation/UIKit/UISearchController/searchResultsUpdater) property is often the view controller that’s set during initialization.
