Apple Mach-O linker Error Xcode 6.2

i'm sorry if this question is repeated, but i only asked because i didn't find a solution in other related questions.

I started a new project in Xcode 6.2

Imported AFNetworking using pods.

Imported SWRevealViewController by dragging the two files (.h and .m) into the project.

Everything looks fine but when i build the project to test it gives me this insane error below.

I'm going crazy with this error.

Please see the image below:

Does anyone know how to deal with this?

Thanks in advance.
