There was an interesting discussion about reactive UIs yesterday (https://news.ycombinator.com/item?id=24599560). Sounds like Swift have it fairly sorted. Is there anything like React Native for Swift rendering to html? A sort of “Swift Non Native”?
I think SwiftUI is still settling, so I expect to see more movement in this are in the short-term future. But I don't see Apple releasing an HTML-emitting-SwiftUI by themselves.
