alt Hacker News> ObjC is still around but feels like legacy to me
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.
And yes, you're absolutely right. Apple is making a choice here, and they absolutely have impact on what the developers "get to use" - much as .Net succeeds largely to vendor choices on Windows, too. And developers get to suck it up! That's the three axis thing again: vocation, art, job. Swift and .Net both got a huge kick from the "job" department. That's how it goes.
