tamil1980/gitdemo ? reverse-engineered prompt

Build me a simple iPhone app in Swift that feels like a clean starter project I can open in Xcode and run right away.

I want it to have a polished first screen, a couple of basic sample views so I can see how the app is structured, and enough real code that it doesn’t feel empty. Make it easy to build on later, with sensible organization and working tests if they fit naturally.

Please keep the design modern and simple, and make sure the app launches without errors. If you need to check anything current in the Apple docs or look up best practices, go ahead and do that. I mostly want a solid demo app foundation that looks nice, is easy to understand, and is ready for me to extend with my own ideas.
