错误：链接器命令失败，退出代码为1（使用-v查看调用）

Question

When I use GooglePluse Library file it works on iphone simulator.

But when I run it on device it gives the following Error:

 ld: duplicate symbol _OBJC_CLASS_$_GooglePlusSignIn in /Pratik workspace/Fitness 
     app/Fitness Ap/Fitness/lib/libGooglePlusUniversal.a(GooglePlusSignIn.o) and /Pratik 
     workspace/Fitness app/Fitness Ap/Fitness/lib/libGooglePlus.a(GooglePlusSignIn.o) for 
     architecture armv7 clang: error: linker command failed with exit code 1 (use -v to 
     see invocation)

Answer 1

you will have 2 files with same name that's why it is giving error like this.

go in targets ->Build Phases ->Compile sources and try to remove GooglePlusSignIn file.it will be there i think. then run again and let me know whether it is working or not..!!!

Happy coding...!!!!
