Link Error

I tried to use your library but with no luck. I got the following error:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_Hero", referenced from:
      objc-class-ref in registrar.o
ld: symbol(s) not found for architecture arm64
clang : error : linker command failed with exit code 1 (use -v to see invocation)
