What advantage does NSUinteger have over uint32? I realize that on a 64 bit machine, it would be a uint64.
"Advantage"? None, really. It's a question of what you're trying to express -- do you want specifically a 32-bit unsigned integer, or do you want an unsigned integer that reflects the architecture's word size? For instance, there's no particular reason to limit NSArray's capacity to exactly 2^32 items all the time, so -count is defined as returning an NSUInteger -- 2^32 in 32-bit, or 2^64 in 64-bit. (Also consider the analogous size_t type.)
