Why do we have to import Factbook.h if we already have @class?

Why is it that we have to still import the Factbook.h file to the ViewController if we already said in the ViewController.h file that we wanted @class Factbook; ?

Using @class does not automatically make that class available to you. Instead, it's just a promise to the compiler that the file in which that class is declared will be #imported in the corresponding .m file.
