What *is* it simulating when I select iPad. An iPad 1? iPad 2? Neither? Is it even attempting to be clock for clock, or just running with whatever speed your machine has? Is at attempting to run multiple threads ala an iPad 2? Force a single thread on iPad 1?
And, obviously, the same questions for the iPhone selection. Will iPhone (Retina) act like an iPhone 4?
It's actually none of the above. It's running your code on Mac OS (not iOS) but using the iOS frameworks (well, frameworks using the iOS source code that's been recompiled to run under Mac OS).
This means that the iOS APIs are (mostly) there intact (because the iOS frameworks are there), but the underlying behavior (things like the memory model) follow Mac OS semantics. The Mac-OS-ness is pretty well hidden in most cases, but it's not an iOS environment through and through.
