    text
    copied!<p>I've gotten the error "linker command failed with exit code 1 (use -v to see invocation)" on my program, and I'm not sure what to do. Yes, I know there are other questions, I read them and tried the different solutions, but I think the problem is different. I've checked both in the project files stored on my desktop and in the one in Library/Developer, but I can't find any duplicate classes even though thats what it tells me.</p> <p>I can give you my code too, if you need it, but hopefully I won't have to. Thanks! :D</p> <p>Full error report: Ld /Users/ethen/Library/Developer/Xcode/DerivedData/ProjAllele-asuihysyexvjvmdsgfladthghavb/Build/Products/Debug/ProjAllele normal x86_64 cd
