I noticed that after adding certain frameworks to a project in Xcode, you don't have to import any of its header files in order to access its classes. How come those classes are "magically" available without the import?

Look for yourProjectName-Prefix.pch
file. There you'll find:
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#endif
Inside the #ifdef
statement you can add any files you like that will automatically imported throughout you whole project.
