    "
    linker command failed with exit code 1 (use -v to see invocation)
    "

    What can be done ?

    That's a very generic error, need more information. A screenshot of the entire Xcode window might help. Try cleaning the project or re-exporting into a fresh directory.

    You may have duplicate SDKs - did you add Heyzap after you exported or any other 3rd party SDKs

    @eyal Try and change the bitcode from "Yes" to "No". Might help not pretty sure if this related somewhere to your issue but linker command issue has been sorted for us in similar way in past

    Well I took out heyzap from anywhere in the game and now I don't have this error but it's a stupid solution since

    1. The same game with zig zag and heyzap works great
    2. The same game with switch and heyzap doesn't work
    3. The same game with switch and without hey zap words

    ??????

    In xcode, go to build settings section-> search for bitcode -> if it is yes, change it to no Screen Shot 2016-07-13 at 4.12.31 PM.png

    @eyal But I guess in your case, issue is something different, still just try

    Doesn't have anything to do with zig zag or switch. I think its your 3rd party SDK

    Export a new Xcode project and don't add Heyzap again because it's already included if you are using rewarded video.

    Just add any other 3rd party SDK you need

    @bmsingha makes a good point also you can try bitcode

    ld: 1034 duplicate symbols for ....

    (this hints that the error is due to duplicate files you added)

    Thank you for that, but I didn't add any code yet to the file.

    In BB I have rewarded videos but I also chose ad interstitials for example

    it's a new export without anything added to it

    What version of Xcode are you using (seems to be Xcode 6 most likely)? Should be Xcode 7 if you are on the latest versions of Buildbox.

    @Aaron F Yeah think so due to duplicate symbols. @eyal, You don't have option? It would be there in btwn info and build phases

    I'm having the same problem. I'm not using any ad networks, I'm using the latest version of Xcode but I do not see any option to change bit code
