Actually, Apple's devices have inspired AdaCore customers to want
a way of translating Ada to whatever runs on iOS. It's done via C,
currently, IIUC. Since much of iOS inherits the C-tradition, and since
AdaCore had already put efforts into that kind of translation,
that's a reasonable choice.

Why layers of Unix on Unix?

If Unix needs to be between Ada and the OS for GNAT to work,
then why not just use the BSD Unix that Macs have got?

It seems as though programmers like putting much effort into making
their programs work with autoconf and xyz-ports.
This takes away much time that could be spent on making programs just
work on the most wide spread flavors of Unix. Just in case, that
includes Apple BSD and Linux for Android.
