Question

I get duplicate symbols error after I updated my Xcode. (find the code down) Does anybody get this too? And how could be solved?

Answer 1

I did not want to change any of these settings since no one really knows what other side effects these may have. So I iust globally searched for that variable name, replaced the name the caused the conflict in one class to variable_Classname.

That solved the issue for me without changing any setting
