Apple promotes Swift heavily but the results are not really encouraging. I don't think the "so-so" results are entirely because of Swift (probably due to newer, less battle tested software and also newer/younger devs) but still the fact is, all the not-so-great new software from Apple came with Swift rewrites, hard to not make a connection...
That's a leap, but I understand your point of course. It _MIGHT_ also be said it all came from ObjectiveC experts having a first go at Swift, too. Or from groups that were run by some common set of "get it out the door" middle management types.
Or any of a thousand reasons.
And of course, Apple has a middle management problem, but that comes with Tim Cook's style; he cares about values that are just not conductive to progress and excellence. It all ends up about "getting shit done" and not caring that much if the results are actually any good. So, they do stuff on schedule and are content with it no matter how bad it is, typical careerist behavior.
To be fair, a lot of our modern society seems to have been overtaken by these types of people, they are very popular and very "successful"; it's more noticeable at Apple because it used to be very different...
