I’m building a desktop app (used Antigravity to build the app + Claude Pro for coding help). Good progress but still lots of tweaking, and I still need to build the iOS app in Xcode.

I keep hearing about Claude Code, can it actually modify a repo automatically like Antigravity, or is it just faster chat? Anyone using it for real app development (desktop + iOS)?

Looking for ways to speed this up without rebuilding everything twice.
