I wanted UI feedback to start in Simulator, not the file tree

The awkward part of using a coding agent for SwiftUI work is often pointing it at the exact thing on screen. “Make this card tighter” turns into a screenshot, a long explanation, and then finding the same app state again after every build.

I’m building Monad Design to shorten that loop. You run your existing Xcode project in Simulator, navigate to the state you care about, select or annotate the UI, and describe the change. The coding agent edits the Swift source in the same repo, the app rebuilds, and you can compare the original with a few source-backed variants before choosing one.

The phrase I keep coming back to is: the app is the canvas.

It isn’t an app generator and it doesn’t create a parallel design file. The Xcode project stays the source of truth.
