Architectural Design Pattern - MVVM (Model-View-ViewModel)

Project

WebSocket.swift - A WebSocket is a network protocol that allows two-way communication between a server and client. Unlike HTTP, which uses a request and response pattern, WebSocket peers can send messages in either direction at any point in time.

CityAQIModel.swift - Data model class

AQIViewModel.swift - ViewModel for buisness Logic

ViewController.swift - View Controller Class contains UI Logic to display the data

AQICustomTableViewCell.swift - Custom Cell

Known Issues: The App doesnot use CoreData, so data is not persistant for now. The time to get the Data is set for 10sec interval that user can feel the updates happening in real time. User can update the timeToRefresh variable in WebSocket.swift class to increase/decrease refresh time
