A NIB file contains many hash based unordered data structures, and won't have a byte for byte identical representation from one save/ compile operation to the next - even when the represented interface is identical.

Okay, thanks Jon,

If you're producing unflattened NIB's via ibtool's --flatten NO, or Xcode's IBC_FLATTEN_NIBS build setting, and you're primarily interested in detecting semantic changes to the file you could instead MD5 the result of running "ibtool --all" against the produced NIB file. You won't be able to use "ibtool --all" against a flattened/ stripped NIB.
