Just like there is nothing UNIX about Gnome or KDE. I don’t really get your point. You try hard but the fact is that macOS has a very strong UNIX underpinning with zero signs that it is going away.
UNIX is not going away, you are the one trying to put words on my typing.
I am talking about the Apple developers culture, from those developers that care about Apple platforms, regardless of what powers the bottom layer of the OS.
UNIX can exist until the end of days at Apple, that is not what matters to Apple application developers.
As for GNOME and KDE, they are lego pieces on Linux, a fragmented experience where the command line is worshipped, for most users running something else doesn't matter, or they even change environment every couple of days, this is not what Apple culture is about.
I don’t understand what you mean, macOS and iOS share the same kernel. They are both POSIX UNIX.
Also, macOS isn’t going to stop being UNIX based, it’s XNU/Mach based on BSD, that’s not going to change without a entirely new OS written from scratch.
What’s not UNIX about Swift/Xcode, it’s just a language / app, what don’t I get here.
Do you think they want to abandon Unix and roll their own OS from scratch?
Of course, it is not going to stop being UNIX, except for the little detail that POSIX is mostly irrelevant for what is sold on Apple store for any kind of their devices.
This is the ecosystem that Apple and developers that buy into Apple ecosystem care about.
Those that were buying Macs to do GNU/Linux work were a welcomed addition in times of need, that is all.
I advise reading books like The Cult of Mac and Folklore.
AppKit apps can and do interact with POSIX APIs all the time. Apple can't just pull the rug out from under them like Google might do with Android apps, for example.
Can you make an application on Linux using POSIX APIs? How about on Android? Your argument seems to be macOS is not a UNIX because POSIX doesn’t specify a GUI toolkit, but this is quite frankly absurd.
What is absurd is the way every UNIX afficionado is trying to turn my words around.
I talk about the culture of the application developers and what Apple developers that are on the platform since the System days care about, and keep being told Mac OS X is an UNIX.
Of course it is one, that is not the point being made.
