# NSView.LayerContentsRedrawPolicy.crossfade

Redraw the layer contents at the new size and crossfade from the old contents to the new contents. Use this in conjunction with the NSView.LayerContentsPlacement constants to get a nice crossfade animation for complex layer-backed views that cannot update correctly at each step of the animation.

## Declaration

```swift
case crossfade
```
