Duplicate symbol issues

Question

During a refactor of an iOS project, I ran into this bear of a bug. During the linking phase, I get this message:

ld: duplicate symbol _OBJC_IVAR_$_Ti

Answer 1

I had a same issue. the problem was that i had two libraries that contain same .m file.

like this

lib.a - for device.

libCauly-universal.a - for simulator and device.

so i deleted one.
