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

I tried to remove

Answer 1

Below Patch work for me..:)

Code recommended to use warning flags and set GCC_NO_COMMON_BLOCKS to YES.

Setting it back to NO solved the problem!
