Which - in my considered opinion - makes them so much worse.
Is it because writing native UI on all current systems I’m aware of is still worse than in the times of NeXTStep with Interface Builder, Objective C, and their class libraries?
And/or is it because it allows (perceived) lower-cost “web developers” to be tasked with “native” client UI?
Aware, yes. Interested, no - closed source philosophy, and the way Apple implements it specifically, turn me off hard.
