Well, the problem here is in your own words: you say `My belief is` - and so it is. I cannot and would never presume to tell you what you believe. Yet I believe otherwise. Swift won on multiple axes; ObjC is still around but feels like legacy to me, much like Pascal does: influential (heck, I use ObjC terminology when describing OO concepts, over Smalltalk!) but not, like, a living language at this point even though its death might be, um, a lot more rumor than fact.

Yes, it feels like legacy because Apple is making it into legacy. Do you not admit that Apple's actions have a profound effect on the relative adoption of the two languages among Apple developers?
I would note that Swift is, like Objective-C, almost nonexistent outside of the Apple ecosystem, even though cross-platform use is possible. Developers who are deliberately outside the Apple ecosystem are generally not interested in a programming language controlled by Apple.
