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.

    Remove files of SurveyDelegate from project. Check the project directory in Finder for SurveyDelegate files. Remove them and recreate in XCode if necessary. Don’t forget about cleaning (Cmd + Shift + K).
