I think the error says you have not defined a member function of the class. In my case I forgot to define the constructor function and got this error. It usually depends on the compiler that you are using, for some compliers this error is not seen.

You need to add necessary framework to your project. Check all third party party framework and search its required framework for support. For eg if you add google analytic then you need to add CoreData , Foundation etc framework. There is some framework is missing for which third party framework needs.

  1. Press "Cmmand+Shift+K" to clean up, and quit Xcode.
  2. delete the cache Run "rm -rf ~/Library/Developer/Xcode/DerivedData" in terminal
  3. open the project and re-build it
