This built on top of the iOS build system and everything is intertwined in both directions at least a few times. I've seen builds working starting the iOS app from command line, only to break _everything_ just starting the application from within Xcode. And Android? I didn't even look into it anymore.
I think they're at 0.57 or something and that version number just wants to tell you one thing: We're going to break your shit some more in the near future before the dust finally settles.
