Shipped my first iOS app entirely with Codex — what worked, what surprised me

Just shipped Rushi — my first iOS app, built solo with Codex over the past 4 months. Wanted to share what I learned, especially for anyone considering Codex as their primary coding partner for an iOS project. Background I'd never written Swift before. Started with Codex as my pair-programmer, learning Swift by doing as I built. The app is a Buddhist toolkit — sutra reader + 108-bead mala counter + sutra calligraphy practice. Free for the first week, then $1.99 — early users keep it free forever
