AnderGoig/github-contributions-ios — reverse-engineered prompt

Build me an iPhone app for people who want to see their GitHub contribution graph on their Home Screen.

The app should let someone enter or choose their GitHub username, fetch their contribution activity, and show it as the familiar GitHub style grid. It should include iOS widgets so the graph can live on the Home Screen, with different widget sizes. Let users pick from a few color themes so they can customize how the graph looks.

Keep the experience simple and polished. The main app can focus on setup, previewing the graph, choosing a theme, and explaining how to add the widget. Make it feel like a native iOS app built with Swift and SwiftUI, and support modern iOS versions. If you need current Apple or GitHub details, look them up online.
