Unless Apple are activly working on UXKit a better bet would be an implementation of UIKit with SpriteKit, with sane &#x27;defaults&#x27; for Mac OS. I&#x27;ve missed something like CollectionView on Mac OS with same API as UIKit.<p>By sane default I mean something like: 
Tab Bar on IOS, Slidable Side Menu on iPad and regular side-panelMac OS.<p>UXKit has some issues, e.g you can&#x27;t swipe back with the touchpad. So I take it has some work left before being a complete replacement of AppKit.
