iOS Messaging App Development -- 2

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.
