Quick Fix for LLVM Compiler Reachability.h Warnings

If you are using Apple’s LLVM compiler and their Reachability.h file you may be getting warnings like this:

Reachability.h: warning: Semantic Issue: Declaration of ‘struct sockaddr_in’ will not be visible outside of this function

Luckily, there is a quick way to fix this. Simply add this import line to the includes section of the Reachability.h file:

Bam! Warnings gone. Hope this helps all you app developers using Apple’s latest preview releases that technically don’t exist because mentioning they exist would be against the Apple-Developer confidentiality agreement. ;)

For anyone unable to see the code in the answer on this page (I can’t). Add:
#import to the include section of Reachability.h.

Okay the include file name got smudged in my comment below. It should be netinet-SLASH-in.h where the -SLASH- is replaced with a forward slash.
