# completionCurve

Indicates the animation completion curve for an interactive transition.

## Declaration

```swift
var completionCurve: UIView.AnimationCurve { get set }
```

## Discussion

Discussion When the interactive part of a view controller transition is complete, you can set this property to indicate a desired animation completion curve. Default value is UIView.AnimationCurve.easeInOut. During the interactive portion of a view controller transition, the animation curve is linear.
