Any ideas? looks like : /Developer/Xcode/DerivedData/${myProjectName}-clyoxovxkkbdatbaffwxxviwprhx/Build/Intermediates/${myProjectName}.build/Debug-iphoneos/${myProjectName}.build/Objects-normal/arm64/main-301E0F77E3874AD.o

[kimzerokim]

nope. I fix the problem... because of duplicated files. (I just re-cleanup my projects. Thanks.)

@ky200223 hey can you elaborate on your solution for this? I'm getting the same error

[kimzerokim]

@cschellberg95 That issue is already rotten in my mind.. :( Anyway I was trying to cleanup the project using Product > Clean and re-build. If isn't resolve you issue, maybe you can see some duplicated files on your xcode dir tree. Just delete that files. I hope this helps you :>

I'm not able to fix it in unity version 5.6.1f1

[funkyLover]

Sorry @noopuraspire , I don't work with unity quite a while, I can't remember any details for this issue. you can make sure you do all things done mentioned by this repo tutorial. and here is some problems I got before. if still down. I think you can just try another c++ Language Dialect Option.

[noopuraspire]

thanks @funkyLover , I will look into it
