Why is there an NSInteger?

Question

If NSInteger is just like a regular int then why does it exist and what is its purpose in being called NSInteger?

Answer 1

Other than the typedef being different on different systems (long on 64-bit systems, int on 32-bit), there isn't much of a reason.

Arguably, it gives the impression that an NSInteger is an object, when it's not.
