This is because to create an instance of an NSString object, one must send a
message to the NSString class object. In the line of code provided, you are
sending a message to the NSString class object which will in turn, provide
you with an NSString class instance, which is different. The key is the
conceptual difference between a class, and an instance of the class. The
NSString class object represents the class itself, whereas an NSString
instance is an object of type NSString.
