This is fascinating work, amazing job to the team!

Does SwiftUI have properties that uniquely make this type of interpreted system possible, or could it also use UIKit under the hood? On the surface, it seems like UIKit might be more difficult since you’d probably need to parse all of the obj-c header files in addition to the .swiftinterface.

Very cool stuff, excited to follow along how you all develop the product!

Thanks! Yes, it works just as well with UIKit. Fortunately Xcode can synthesize a .swiftinterface for Obj-C frameworks bridged into Swift, so we use that to generate a compiled interface for UIKit (and other Obj-C frameworks).
