# UIWindowScene.ActivationRequestOptions

An object that contains information you want the system to use when activating a new window scene.

```
class ActivationRequestOptions
```

## Overview

Create a [`UIWindowScene.ActivationRequestOptions`](/documentation/UIKit/UIWindowScene/ActivationRequestOptions) object before you activate a scene using the [`activateSceneSession(for:errorHandler:)`](/documentation/UIKit/UIApplication/activateSceneSession(for:errorHandler:)) (Swift) or [`activateSceneSessionForRequest:errorHandler:`](/documentation/UIKit/UIApplication/activateSceneSessionForRequest:errorHandler:) (Objective-C) method of [`UIApplication`](/documentation/UIKit/UIApplication). Use this object to specify the preferred presentation style of the new scene.

## Topics

### Positioning windows

[`placement`](/documentation/UIKit/UIWindowScene/ActivationRequestOptions/placement)

The placement you prefer when the system activates the window scene.

[`UIWindowScenePlacement`](/documentation/UIKit/UIWindowScenePlacement-swift.protocol)

The placement of a window scene in the workspace.

[`UIWindowSceneProminentPlacement`](/documentation/UIKit/UIWindowSceneProminentPlacement-swift.struct)

A placement that indicates the system should present the window more prominently than others in the space.

[`UIWindowSceneStandardPlacement`](/documentation/UIKit/UIWindowSceneStandardPlacement-swift.struct)

A placement that indicates the system should present the window using the default style of the system in the space.

[`UIWindowScenePushPlacement`](/documentation/UIKit/UIWindowScenePushPlacement-swift.struct)

A placement that indicates the system needs to present the window by pushing it onto another window.

[`placement`](/documentation/UIKit/UIWindowSceneActivationRequestOptions/placement)

The placement you prefer when the system activates the window scene.

[`UIWindowScenePlacement`](/documentation/UIKit/UIWindowScenePlacement-c.class)

The placement of a window scene in the workspace.

[`UIWindowSceneProminentPlacement`](/documentation/UIKit/UIWindowSceneProminentPlacement-c.class)
