IOS App Agentic Engineering · markus-smile bundle End-to-end agentic engineering for iPhone apps, from idea to a secure App Store release through 8 gated phases. Use when someone wants to build, plan, or ship an iPhone/iOS app — especially a non-programmer ("vibe coder") asking to create an app, pick a tech stack (SwiftUI, React Native, Flutter), choose a backend (CloudKit, Supabase, Firebase), publish to the App Store, or make their app secure. Also use when an iOS project shows symptoms of skipped planning - hardcoded API keys, no threat model, Firebase test mode, missing privacy manifest, or App Store rejection.
