More like Apple wants you to use their computers. If it was legal I'm sure Microsoft would have figured out how to compiler iOS apps in Visual Studio. It's not magic, it's just obscured and prevented through legalese.

I can either be charitable or accusatory :) It's not so obscure as to how one might run Xcode tools on another Unix-like OS. It's just illegal. Apple tightly controls their entire stack.
