# UICollectionViewDelegate

The methods adopted by the object you use to manage user interactions with items in a collection view.

## Declaration

```swift
@MainActor protocol UICollectionViewDelegate : UIScrollViewDelegate
```

## Overview

Overview A collection view delegate manages user interactions with the collection view’s contents, including item selection, highlighting, and performing actions on those items. The methods of this protocol are all optional. When configuring the collection view object, assign your delegate object to its delegate property. For more information, see UICollectionView.
