[swift-dev] [RFC] Finer grained OS checks

[Karl Wagner]

 I remember somebody telling me it was, but it was years ago and I'm probably remembering it wrong.  Fair enough though; I got told on that one 😶
  

  
I'm standing by the principle - it shouldn't matter if you're running in a simulator or not. Use a compile flag if you must know, but in general I disagree with a compiler flag for determining the runtime platform for two platforms with the same API and triple.

The fact that it runs on a simulator instead of a real device is not such a vital distinction (or shouldn't be) that we need integrate it in the language. What would we do in the future if there ever was a real x86 iOS target?
