This is what I do. Is SUPER productive & easy!

I do ALL the UI logic on Rust: Internationalization, formatting, etc and in SwiftUI/JetpackCompose only pain stuff and send/get a single JSON internal FFI endpoint.

So my "records" are just:

     App:
        {title: "Factura #F10", bg-100:"black", font:"...", ...}
     Data:
        Invoice {total:"$ 1'000.000,00", ...}

my UI logic only deal with "clicks", dispatch & theming.
