Drop in your whole Xcode project. Every screen becomes browsable Jetpack Compose with a real rendered preview — using your own components, sample data and colours, so it looks like the app rather than a wireframe.
The whole folder — Xcode project and all. Every screen, component, model and colour in it becomes browsable in a few seconds.
Indexed entirely in your browser. Your source is never uploaded.
A compiler translates the SwiftUI it understands directly in your browser — no model call, no network, no cost. That covers most of a typical screen and runs in about a millisecond.
The screenshot comes from a Compose renderer compiled ahead of time, not from compiling generated code at request time. There is no compile step to break, so there is no error screen to land on.
Anything the compiler cannot translate is sent to a model constrained to a fixed vocabulary. Whatever still has no equivalent renders as a labelled placeholder you can click, rather than as something that looks right and is not.
