Great Job!
Although Currency Converter is a simple application, creating it illustrates many of the concepts and techniques
of Cocoa programming. Now you have a much better grasp of the skills you need to develop Cocoa
applications. You learned:
To compose a graphical user interface (GUI) in Interface Builder
To test a user interface in Interface Builder
To specify a class' outlets and actions in Interface Builder
To connect controller-instances to the user interface by using outlets and actions in Interface Builder
To implement a model, a view and a controller in Xcode
To build applications and correct build errors in Xcode
Great Job!
