# trimEnd

The time, in seconds, at which the animation stops.

## Declaration

```swift
var trimEnd: TimeInterval? { get set }
```

## Discussion

Discussion This property is nil by default, which plays the animation until time = duration. If you set a value, the animation edits the duration according to the specified ending time.
