# NCWidgetSearchViewController

An object that provides a default search view within a macOS Today widget.

## Declaration

```swift
class NCWidgetSearchViewController
```

## Overview

Overview The NCWidgetSearchViewController class provides a default search view within a Today widget. A search view controller works together with its delegate to perform searches on the user’s input and display results from which a user can choose. To learn about the search view controller delegate methods, see NCWidgetSearchViewDelegate. When a widget is in editing mode, it can enable search for new content by instantiating an NCWidgetSearchViewController object and presenting it using present(inWidget:). The search view controller displays the default search field and a list of results. It uses its delegate to perform the search itself.
