Are Xcode build settings exposed as pre-processor variables? I know
they're available when pre-processing Info.plists, but can't find a
way to use them in source code files (.m).
It's not Xcode build settings, but gcc does have predefined macros
that can tell you wether GC is on.
#ifdef OBJC_GC
#error This code doesn't support garbage collection
#endif
Try it with
#if __OBJC_GC__
This also shows up when getting the list of pre-defined macros via
cpp -ObjC -fobjc-gc -dM < /dev/null
