Duplicate error on xcode

ld: duplicate symbol _main in /Users/.../i386/main-7E8F26AC10F53546.o and /Users/.../i386/main-B9843B6026D6EFA4.o

Anyone help with this error?

Sounds like you have more than one main() function in your code.

ThiefMaster is right.. search for "main(" in your project and try to clean all targets and build again.
