Swift preprocessor if not flag

Is there a Swift compiler directive for #if not?

I know this could work

#if myFlag
    // ignore
#else 
    bar()
#endif

But it is not pretty if there is nothing between if and else.

Solution

  • I wasn't trying enough, I found out 

    #if !myFlag 

#endif

    works well !
