duplicate symbols for architecture x86_64

This usually happens when multiple libraries (object files) are sharing the same variable/function name, generating duplicate symbols. The compiler gets confused about which one should be invoked.
To solve the issue, we can either make functions inline or use macros instead of the function name. We can also make function scope local to the library only by using static.

I had also faced the same problem.Somehow some frameworks got added twice in our project.So I fixed it by removing the duplicate frameworks from project settings -> build phases -> link Binary with libraries then check some frameworks may be added multiple times, just find the repeated frameworks and remove them, then it should work fine.

duplicate symbols for architecture x86_64
This means that you have loaded same functions twice. As the issue disappears after removing -ObjC from Other Linker Flags, this means that this option result that functions loads twice:
from Technical Q&A
This flag causes the linker to load every object file in the library that defines an Objective-C class or category. While this option will typically result in a larger executable (due to additional object code loaded into the application), it will allow the successful creation of effective Objective-C static libraries that contain categories on existing classes.
