I really believe this is the way forward, native platform UI built by AI.

I'm trying it now with an app and so far it's working really well. I build what I can cross platform, the non-ui stuff, then have AI build the UI for each platform.

It even implemented native low-level graphics on each platform: metal, vulkan, and d3d12. It builds SwiftUI on Apple platforms, WinUI3 on Windows, GTK4 on Linux, Compose on Android. The cross platform stuff is Zig with a C ABI.

And yeah, it's a bit terrifying how fast you can iterate. I've built for all these platforms in about a month. It would have taken at least a year, maybe more before. I haven't even optimized the process by having AI agents follow my lead automatically, so as I finish features on the primary platform they could start building the others by watching. Requires some setup I haven't tackled yet (VMs for all platforms with agents waiting).
