Does this mean that you can't have 64 bit Cocoa applications?
64-bit is usually only needed for high-precision maths or maths in
huge number ranges. Lots of data processing and number crunching. In
that case, you'll usually have a command-line tool or daemon to do
the actual work, and you can have your Cocoa app talk to that using
NSTask, pipes etc.
For that reason, Apple have not (yet?) ported any of Cocoa to 64-bit.
Nor have they ported any of Carbon to use 64-bit ints and stuff like
that, either. So, yes, you can't have 64-bit Cocoa applications. The
rationale I heard was that there was simply no need for 64-bit
versions of all the APIs. If you actually have a need for that, I'd
suggest you file a detailed bug so Apple will know what your needs
are and so they can work on a solution.
However, Cocoa is not incompatible with 64-bit. Any Cocoa app will
run just fine on any 64-bit system that can run a flavor of MacOS X
(within reason -- if the app doesn't run on that OS X version on a
32-bit CPU, it's unlikely it'll work on 64-bit, obviously).
And also note that this doesn't mean you can't use a long long in
your Cocoa apps. You can, just fine.
