compositingFilter
The Core Image filter used to composite the view’s contents with its background.
Declaration
var compositingFilter: CIFilter? { get set }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.
