Clearing the Red Errors in Xcode After Rork Max Generates Swift Code: A Priority Order
A priority order I use to clear the wall of red errors that Rork Max-generated Swift projects show on first open in Xcode, drawn from ten-plus years of indie iOS work.
From a Rork-Built App to Monthly Break-Even at 100 Yen Subscription: Indie Numbers from May 2026
A small Rork-built utility app reached month-over-month break-even on a 100 yen subscription combined with AdMob. May 2026 numbers, decisions, and what I deliberately left out.
expo-haptics Silent on Production Builds in Rork — Simulator, Device, and Low Power Mode Pitfalls
Your Rork-generated app taps the favorite button and nothing happens on TestFlight — but Expo Go works fine. Lessons from a wallpaper indie shop on the five most common reasons expo-haptics goes silent, with working call patterns for each.
Rork-Specific 'expo start --offline forbidden': Four Causes in Rork's Template Config
