ld: 1 duplicate symbol for architecture x86_64 build failed

I am getting build failed, I tried so many things but I couldn't figure out how to solve it

duplicate symbol _GSDK_GTMNSDataZLibExportToSuppressLibToolWarning in:
    /Users/Macpro/Documents/evoteam/ClassifiedTemplate/../Pods/GoogleUtilities/Libraries/libGTM_NSData+zlib_external.a(GTMNSData+zlib.o)
    /Users/Macpro/Documents/evoteam/Pods/GoogleUtilities/Libraries/libGTM_NSData+zlib_external.a(GTMNSData+zlib.o)
ld: 1 duplicate symbol for architecture x86_64

thank you for any help.
