What are some uses of the NSProxy class. Why would you want to be able to have the description of an object that doesn't exist?

Answer 1

The NSProxy class provides a basic implementation of a class whose instances are used to stand in for other objects. We need NSProxy to implement transparent distributed messaging or for lazy instantiation of object.

Answer 2

An NSProxy is an object that forwards messages to an object on a different thread, in a different process, or even on a different host. Read the documentation on Distributed Objects.
