# backwards

An option that shows the first animation frame while playback progresses to the beginning position.

## Declaration

```swift
static let backwards: AnimationFillMode
```

## Discussion

Discussion For example, if you wind a hand-waving animation’s duration back one second by setting trimStart to -1.0, a fillMode of backwards determines that the hand holds its initial appearance for one second before waving.
