Inspired by game development UIPheonix is a super easy, flexible, dynamic and highly scalable UI framework + concept for building reusable component/control-driven apps for macOS, iOS and tvOS. The same API apply for cross platform development! Think of it as using Lego blocks, you can use similar ones and move them around easy as pie.
