LookInsideApp/LookInside ? reverse-engineered prompt

Build me a Mac app that lets me inspect the UI of a running iOS or macOS app in a really visual way.

I want to open the app on my Mac, connect to an app that has a small helper package installed, and then click through the interface to see every view, layer, frame, screenshot, and important property live. It should also handle SwiftUI so I can understand view trees, modifiers, and layout details, not just UIKit or AppKit. If something changes in the running app, I want to see those property updates right away.

Please make the experience feel simple and polished, like a developer tool I can actually use while debugging. If you need to check current setup details or dependency guidance, look up the latest docs online.
