As an iOS developer, I would say state of web development is not true for iOS. Sure it is slowly evolved to the current state but the framework much more thought out than their web counter part.
Seriously, the reactive frameworks (any really: React/VueJS/Preact/...) used in tandem with a separate state container (Redux, Vuex...) is a much better "thought out" approach to application programming than anything in the Cocoa/Swift world.
