Yes, there are new APIs in UIKit related to Liquid Glass. The new design system introduces Liquid Glass, a translucent and dynamic material that enhances the look and feel of system materials and controls. UIKit has been updated to support this new design, and there are specific APIs to adopt the Liquid Glass look and feel in your apps. These APIs allow you to create interactive layers that float above your content, providing a distinct control layer for user interaction. You can use these APIs to update your app's UI components, such as navigation bars, toolbars, and custom elements, to incorporate Liquid Glass effects.
