# quartzcore Generated QuartzCore / Core Animation binding (`cpc-bindgen --framework QuartzCore --prefix CA --merge`). Ships `Layer` (`CALayer`) so `NSView.layer()` is a real typed object. ```cplus import "quartzcore/quartzcore" as quartzcore; ``` Depends on `objc`. Links the `QuartzCore` framework. [facet_appkit](/docs/packages/facet_appkit) uses it for layer-backed paint.
