[swift-evolution] [Pitch] #warning

[Michael Peternell]

Something similar to #error seems to be already implemented ;)

#if os(iOS)
    import Error_sorryThisDoesntWorkOnIOSyet
#endif

I know it's a hack, but it works :) And the good thing is, there is no way to prevent these kind of hacks.. (but IMHO, #error would look nicer)
