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?
The iOS simulator is not literally x86 iOS. It has changed ABI in incompatible ways in the past and reserves the right to do so in the future. Any real x86 iOS would have a real ABI which would likely differ from today's simulator.
