# currentProgress

The current progress of the animation.

## Declaration

```swift
var currentProgress: NSAnimation.Progress { get set }
```

## Discussion

Discussion This property contains the completion percentage of the animation. Valid values are in the range 0.0 to 1.0, where 0.0 represents the beginning of the animation and 1.0 represents the end of the animation. Changing the value of this property adjusts the progress of a running animation. Setting this property to a value less than 0.0 sets the value of the property to 0.0. Similarly, specifying a value greater than 1.0 changes the value of the property to 1.0.  The NSAnimation class updates the value of this property during the animation. To perform additional tasks at specific progress points, use the delegate’s animation(_:valueForProgress:) method.
