# UIWindowScene.ActivationInteraction

An interaction that facilitates activating a window scene when a user pinches out on the interaction’s view.

```
@MainActor class ActivationInteraction
```

## Overview

Create a [`UIWindowScene.ActivationInteraction`](/documentation/UIKit/UIWindowScene/ActivationInteraction) object when you want to facilitate requesting scene activation when the user pinches open on a view. You initialize the interaction with a closure that the system executes when the user triggers the interaction. The closure should return a [`UIWindowScene.ActivationConfiguration`](/documentation/UIKit/UIWindowScene/ActivationConfiguration) object. You also provide an error-handler closure that the system executes if the scene activation request fails.

To request scene activation from an interaction with a [`UICollectionView`](/documentation/UIKit/UICollectionView) cell, use the [`collectionView(_:sceneActivationConfigurationForItemAt:point:)`](/documentation/UIKit/UICollectionViewDelegate/collectionView(_:sceneActivationConfigurationForItemAt:point:)) method.
