Develop Android Apps in Swift

Has anyone heard about Scade or built anything with it? I am not a developer or in any way affiliated with the project. It looks a little premature, as it is still in beta and not officially released.

I found this project particularly interesting, especially given the recent news of Google Fuchsia and Swift.

I recently got into building native iOS applications, but this has me really curious about the differences between Scade and React Native (which I also haven't used before).
