I need a clean, fast iOS app whose main purpose is real-time messaging between users. Everything should feel native to the Apple ecosystem, so please build in Swift or SwiftUI and make sure it passes App Store review guidelines. Core scope • User registration/login (Apple ID or email) • One-to-one chat with text, images, and read receipts • Secure data storage in the cloud (Firebase, Supabase, or a comparable solution) • Basic admin panel to manage users and moderate content • Thorough testing on the latest iPhone and iPad devices I am focusing only on messaging for the first release; payments or push notifications can wait until a future milestone, so keep the architecture modular enough to add those later without a full rewrite. Deliverable is an Xcode project, backend configuration guide, and a TestFlight build ready for my review. Once everything works smoothly and I approve the TestFlight build, we can wrap up this phase and discuss follow-on features.
