already have a React + Vite web app running on a Convex backend. I now need a proper iOS build created using Capacitor—one that runs cleanly in Xcode, works on real devices, and passes TestFlight/App Store Connect validation without issues. Milestone 1: iOS Build Setup • Initialize and configure Capacitor • Generate the iOS project • Install/verify required plugins • Fix any path, asset, or environment issues • Confirm the app launches on a real device (iOS 17+) without manual Xcode hacks Milestone 2: Backend + Auth Integration • Ensure Convex backend calls work on-device exactly as they work on the web • Configure environment variables correctly for production builds • Implement Google Sign-In and Apple Sign-In using official SDKs • Return the same user object/flow my web version expects Final Deliverables: • A fully working Capacitor-generated Xcode workspace that builds and runs on iOS 17+ • Clean configuration for Convex (endpoints, tokens, environment files) • Fully functional Google & Apple login on device and simulator • A short handoff guide (or screencast) covering: – Build commands – Certificates & provisioning – Steps needed for future releases • App ready to be uploaded to TestFlight / App Store Connect with no blocking errors Timeline: ASAP — fast iteration and clear progress updates are important. When replying: Include 1–2 samples (links or screenshots) of past work where you turned a React/JavaScript web app into a native/hybrid iOS build using Capacitor or a similar toolchain.
