I received the following error:
Undefined symbols:
"_OBJC_CLASS_$_SurveyDelegate", referenced from:
objc-class-ref-to-SurveyDelegate in Menus.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
The error was caused by removing SurveyDelegate and was fixed when I removed the code that tried to use a survery delegate. Why isn't it giving normal compile error? I already tried cleaning the project? In fact, it also let me declare a SurveyDelegate
elsewhere and this error wasn't giving either a linker or compiler error.

Objective c id returned 1 exit status - same name, but different problem
