Yes, a property list, binary or not, is definitely interchangeable.
The keyed archive container format is interchangeable, however whether a
particular archive is interchangeable depends on what's in it. Obviously if
a class is only present on one of iOS and Mac OS X, that's a problem. For
arbitrary individual classes present on both OSes, it's difficult to say
anything too concretely. People may have taken advantage of the new OS to
drop some aspects of compatibility.
If your keyed archive contains exclusively Foundation classes, it's our
intent that they should be as interchangeable between iOS and Mac OS X as
between versions of Mac OS X. I don't think we have specific tests to make
sure it works, though, so, well, if it doesn't for something, file a bug.
