ifdef for specific Xcode versions?

Question

I'm currently converting some of my code to compile in Xcode 9 and stumbled over some different behaviour which forces me to use some code only in Xcode 9 and some only in Xcode 8. Is there some kind of ifdef so I can redirect code based on the Xcode version used?

Any help appreciated. Thanks!

There are no conditional compilation preprocessor macros for Xcode versioning. Currently, this is the best you can do:

#if swift(>=3.2)
    // Xcode 9 
#else
    // Xcode 8
#endif

Since Swift 3.2 is available only via Xcode 9 or higher, this should serve your practical needs.
