Google iOS DFP and Analytics for iOS not working together

Question

I'm working on an iOS App where my clients requested to implemente DFP and Google Analytics.

Implementing the ad banners was easy but when I added the libraries requires by Google Analytics, xcode blew up showing 28 errors.

The errors go away when I remove the -ObjC linker flag, but this way the DPF implementation will not work.

Here are the errors, any ideas?

Try including "libsqlite3.0dylib" in your project as suggested here. See if any other library or framework are missed.
