I see the whole thing a bit more holistically. Swift and SwiftUI are both symptoms of the more general malaise, and then contribute back to it.
We had this in hardware, with machines getting worse and worse and Apple getting more and more arrogant about how perfect they were. In hardware, they had their "Come to Jesus" moment, got rid of Jonathan Ive (who had done great things for Apple, but seemed to be getting high on his own fumes), pragmatically fixed what was wrong and did the ARM transition.
With software, they are still high on their own fumes. The software is getting worse and worse at every level, and they keep telling us and apparently themselves how much better it is getting all the time. Completely delusional.
