SwiftWebUI
SwiftUI, and the underlying system for embedded DSLs that it's built upon, is pure genius.It has excited me and invigorated my creativity in a way that I had not felt since Microsoft's WPF/XAML, but unlike WPF+XAML you don't have to work in 2 different languages for the logic versus the declarative UI, and unlike Microsoft I don't have to worry about it being museum'ed and forgotten after a couple short years.See "What's New in Swift 5.1" [0] around 31:15 where they show an example of how you might use full-featured Swift to output HTML. You can immediately tell that it's a hint of something huge and possibly disruptive to come.SwiftUI and its live previews and device-agnosticism are already insanely powerful. There's no reason why that tech shouldn't be applied to web dev as well, and hopefully even ported to Windows/Linux/Android to output their native GUIs.[0] https://developer.apple.com/videos/play/wwdc2019/402/
