# motionEffects

An array of motion effect objects to apply as a group to the view.

## Declaration

```swift
var motionEffects: [UIMotionEffect]? { get set }
```

## Discussion

Discussion The array contains one or more UIMotionEffect objects. When the viewer offset changes, each object in the group is asked for its key paths and updated values. Those values are then applied simultaneously.
