A potential source of confusing is that NSInteger in 64 bit is not
an int, but a long. This means that NSInteger is 64 bit on 64 bit

A general switch from int to NSInteger is therefore probably not
appropriate, but a switch to NSInteger is needed when you want to
store the result of any API that returns an NSInteger.
You're correct when it comes to handling formats of fixed size, but if
you need a primitive's size to be the same no matter what, then you
should probably be using int8_t, int32_t, int64_t, etc. instead of
either int or NSInteger...
