I'm trying to work with reachability in my project. I added Reachability.h and Reachability.m files. But after building project xCode shows me strange errors:
Undefined symbols for architecture i386:

How can I solve this problem?
Probably you forgot to add the SystemConfiguration.framework to your project. If you don't know how to add a framework have a look at this SO question.
