> Your point about Foundation was meaningless and the others just nits. Do you have an actual point to make?
My point, as always, is the truth. You said two false things, which you subsequently admitted were hyperbole. Truth is valuable in itself, and more important than "points", i.e., arguments or motives.
If I were to make a point, though, it's that Objective-C still has a very long life ahead of it, and its complete replacement, if that ever occurs, will be an arduous process, given the amount of extant Objective-C code in the operating systems and first-party apps (not to mention third-party apps). It's not just Objective-C either: C++ is also used quite a bit in the OS. Think of WebKit, for example.
You're not going to be able to hire many people with Objective-C experience nowadays. Engineers with 7 years of experience just writing iOS apps will very likely will have only used Swift in their work experience. I work with 2 of them now.
The article author is a solo indie dev. I'm a solo indie dev. We don't need to hire.
By the way, we could be hired, for the right compensation. Nonetheless, companies almost never try to recruit me, but they still whine about how "hard" it is to find ObjC developers. They're not even looking.
Besides, experienced engineers can learn a new programming language. Do you think that every engineer Apple hired before 2014 had Objective-C experience?
Your original assertion that Apple wasn't rewriting anything.
