I've been working on a very similar framework[1], but wasn't satisfied with the ergonomics enough to release it. My plans were to extend the Swift compiler with JSX-like syntax[2] that makes use of the declarative framework. Of course that's still possible, especially now with a canonical "Apple" way of building declarative interfaces in Swift. I'm a bit sad that with the announcement of SwiftUI my implementation will not stand a chance anymore, but I definitely learned a lot along the way how declarative rendering and reconcilation works in detail. Bottom line - this is very great news for native app development, declarative UI makes it vastly more easy to reason about code.
