# componentClass

The class of components managed by the component system.

## Declaration

```swift
var componentClass: AnyClass { get }
```

## Discussion

Discussion Each GKComponentSystem object manages components of a specific GKComponent subclass. You specify the component class to be used by a system when creating it with the init(componentClass:) initializer. Afterward, you may add components to the system only if their type matches the system’s component class.
