    Hello my friends i'm having a problem trying to export a unity app to IOS. I used Unity 5.6.0f3 and Unity 5.6.2 with no solution. The problem is that when i exported and tried to compile the project in xcode the project does not compile with error:

    Apple Mach-O Linker (ld) Error Group
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

    The app is a VR app that use firebase google card board.

    I updated the pod, changed configurations and everything but the error persist.

    i dont know that to do or what else to change.

    Thank you for the help if someone know the solution for this error.

    Regards

    Hello, looking at the error message, it seems your are trying to link a 3rd party library made for iOS 10.0 and your project is built for IOS 7.0.
    In Player Settings/Other Settings/Configuration, change your "Target minimum IOS version" from 7.0 to 10.0.
    Note: if you are using other 3rd party assets, you may encounter the opposite problem (not compatible with IOS 10.0).
    Good luck !

    Besides of the message above and according to the full image, generally, this kind of error occurs due to duplicate classes and libs in your project folder such as (.h/.m files). You might see these duplicate classes under target->Build phases->compile sources.

    Just look and remove extra classes. Problem will be solved.

    Hello Lug and Julian thank you for your responses, now i fixed one of three 3 errors, I was trying to figure out which the classes are duplicated but I did not find nothing, i see that there are classes with the same name but with a version in the end character of the name. I deleted all with numbers or versions, But i got 100 errors now. I upload the image with the list of the classes. Guys thank you for your responses. Regards
