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

This problem solve here when I deleted (using Xcode) all files .m and .h from Class folder then I cleaned Project (Command + Shift + K) and Builded again. So I drag the files from Finder to Class Folder in Xcode again. Finally, I cleaned and build my Project again...

Good Luck !!!
