Somebody just built and shipped an iOS app in 72 hours. With Claude Code. No Swift experience needed to follow along. The app is Split Party, an expense splitting app. Apple rejected it first, he fixed it, and now it is live on the App Store. The part that got me: the Figma to Claude design loop. He designs in Figma, Claude turns it into real code, and he gives design feedback the same way he would to a human designer. He also added in-app AI with Claude Haiku and paywalls. Full journey, mistakes included. Watch it here: https://www.youtube.com/watch?v=_qBumCflPg8 Course 4 in the classroom is all about this, building with AI agents and Claude Code. If you watched it, tell me: what app would YOU build in 72 hours? Drop it below.
