Apple implemented SwiftUI as a wrapper on top of AppKit and UIKit for macOS and iOS respectively, however architecturally those three libraries are at the same level. This is why I am suggesting us doing the reverse, making our AppKit and UIKit wrappers of SwiftUI. A better way to phrase this is that our partial SwiftUI becomes what Back used to be. So instead of being a bundle embedded in GUI, Back implementing SwiftUI becomes a proper framework standing on its own.
SwiftUI is a new framework, so it would be a while before any major open source release happens.

I am getting increasingly confused here. Why would these particular libraries implement the SwiftUI APIs?
Especially CAAppKitBridge which tries to use Opal backend in gnustep-back to paint gnustep-gui's views into CA's layers, by creating a GL view, scheduling repaints, etc?
Was I under the wrong impression that SwiftUI is a replacement / wrapper around AppKit/UIKit? In fact, Apple's basic tutorials suggest that it sits around / in place of UIKit, so does this discussion even apply in context of AppKit APIs?
What Mac-native open source apps can you point me at to basically understand SwiftUI without reading through tutorials?
