iOS nothing to do with macOS, other than sharing the kernel, which isn't UNIX to start with.

Additionally, iOS only supports a subset of UNIX.

Finally it is impossible to ship an iOS application only using the POSIX subset exposed in OS.

How many iOS apps have your ever shipped?

Of course. It only needs what the applications supposed to run on it need. The same is true about my car entertainment system - it probably doesn't have many tty's and doesn't really need more than one filesystem. Same, BTW, applies to Android - it's a Linux, but it's not really a desktop OS.

Does it have any relevance to knowing the difference between an OS and a GUI?
