# compositingFilter

The Core Image filter used to composite the view’s contents with its background.

## Declaration

```swift
var compositingFilter: CIFilter? { get set }
```

## Discussion

Discussion This property contains the compositing filter stored in the compositingFilter property of the view’s layer. If the view does not have a layer, setting the value of this property has no effect. The default value of this property is nil, which causes content to be rendered without any special compositing effects.
