Can anybody help me with this, its driving me crazy. I looked at every post I could find with a similar issue, and none of it worked.

I installed AFNetworking 3.0 in my project with Cocoapods, it installed, I see the AFNetworking pod in my project.Set built Architure only :YES Whenever I try to build I get the following error:

Undefined symbols for architecture x86_64:

Answer 1

I had the same problem after installing pods to my old project. In my case there where custom linker flags added to the Build Settings of the target, but the $(inherited) was removed so the pods flags were missing (not inherited) therefore no AFNetworking framework were linked.

I suggest to check out is there a $(inherited) row added to the Other Linker Flags section of Build Settings for the target.

Just delete the DerivedData folder and re-try.

rm -rf ~/Library/Developer/Xcode/DerivedData

Answer 3

add below lines to your podfile and reinstall it and add your project name to target.

target 'your project name' do
use_frameworks!
pod 'AFNetworking', '~> 3.0'
end

hope your problem will be solved.
