# stop(blendOutDuration:)

Stops an animation with a fade-out time.

## Declaration

```swift
@MainActor @preconcurrency func stop(blendOutDuration: TimeInterval)
```

## Parameters

- `blendOutDuration`: Time (in seconds) to fade out the animation before it stops.

## Discussion

Discussion This method has no effect if the animation is complete. After you stop the animation, the playback controller becomes invalid. Create a new one with the same resource to play the animation again.
