RenderLayer.Set

struct · iOS 27.0+ · SDK 27.1

struct Set

An unordered collection of unique render layers. ``RenderLayer/Set`` represents a group of layers - for example, the layers a light illuminates (``DirectionalLightComponent/layers``, ``PointLightComponent/layers``, ``SpotLightComponent/layers``) or the layers an entity participates in (``RenderLayerComponent/layers``). Create a ``RenderLayer/Set`` using an array literal: ```swift let layers: RenderLayer.Set = [.defaultLayer, RenderLayer("com.myapp.hero")] ```
