Specifies the supported animation curves.

```
enum AnimationCurve
```

## Topics

### Constants

[`UIViewAnimationCurveEaseInOut`](/documentation/UIKit/UIView/AnimationCurve/easeInOut)

An ease-in ease-out curve causes the animation to begin slowly, accelerate through the middle of its duration, and then slow again before completing. This is the default curve for most animations.

[`UIViewAnimationCurveEaseIn`](/documentation/UIKit/UIView/AnimationCurve/easeIn)

An ease-in curve causes the animation to begin slowly, and then speed up as it progresses.

[`UIViewAnimationCurveEaseOut`](/documentation/UIKit/UIView/AnimationCurve/easeOut)

An ease-out curve causes the animation to begin quickly, and then slow down as it completes.

[`UIViewAnimationCurveLinear`](/documentation/UIKit/UIView/AnimationCurve/linear)

A linear animation curve causes an animation to occur evenly over its duration.
