3.8.1 React (Web) & Swift (iOS)

• Shared API Contracts: The same Node.js endpoints power both clients.

• Socket.io on iOS: Swift apps maintain a persistent connection to real-time channels.

• UI/UX Parity: Both platforms should offer consistent features (posting, chat, trading actions), even if the design is tailored to each environment.

• Maintain an OpenAPI/Swagger spec for every endpoint:

• Ensures the React client and Swift iOS app consume the same structure.

• Minimizes versioning confusion.
