# UIMotionEffectGroup

A collection of motion effects that you want to apply to a view at the same time.

```
@MainActor class UIMotionEffectGroup
```

## Overview

This class behaves similarly to the <doc://com.apple.documentation/documentation/QuartzCore/CAAnimationGroup> class in Core Animation. The key paths and values returned by each motion effect object are applied simultaneously and with the same timing. Because [`UIMotionEffectGroup`](/documentation/UIKit/UIMotionEffectGroup) is a subclass of [`UIMotionEffect`](/documentation/UIKit/UIMotionEffect), you can treat it like a single motion effect in your code. After setting a value for the [`motionEffects`](/documentation/UIKit/UIMotionEffectGroup/motionEffects) property, add the group object to one or more of your views.

## Topics

### Setting the group items

[`motionEffects`](/documentation/UIKit/UIMotionEffectGroup/motionEffects)
