AFNetworking "Undefined symbols for architecture i386" Error

Question

I have added all AFNetworking library files to my project(Which I downloaded from github). I didn't created any other view controller/class etc in my application. I just built my application and found 9 errors "Undefined symbols for architecture". Any help would be appreciated.

I listed down the list of errors.

Undefined symbols for architecture i386:

Answer 1

I think you need to add Security.framework in you iOS project.

Answer 2

Include the "Security" Framework. Everything works fine then.

I was also facing the same problem but now I have found my fault. Do check following frameworks are added if you are facing similar problem

1. Security.framework
2. SystemConfiguration.framework
3. MobileCoreServices.framework
