I'm just starting working w/ Obj-C, so I've got a beginner's question:

Why is it that instance variables are declared in an object's
@interface portion (interface file) while an object's method's are in
the @implementation portion (implementation file)?

I had kind of pictured the interface file as akin to a prototypes
file, while the implementation file contained the actual code.  Since
instance variables are private data, it seems to me that they should
be declared in the implementation file (along with the methods) rather
than the interface file.
