The performance is bad; the developer experience is bad (it's a moving target, not a stable point); it was done to chase a trend (reactive) and to boost other Apple platforms (macOS, watchOS, tvOS, and now visionOS) rather than because it was the right technical solution; the UI and UX it generates is poor; and Apple (but not only Apple) seems to have stopped caring about quality over the last few years.
