SwiftUI MVVM ListView with CoreData

This project is a demonstration of using SwiftUI with the MVVM (Model-View-ViewModel) architecture pattern to fetch data from an API, store it in CoreData, and display it in a ListView.

Features

  • Fetch data from an API.
  • Store data in CoreData.
  • Display data in a SwiftUI ListView.
  • Implement MVVM architecture for better code separation and testability.

Requirements

  • iOS 14.0+
  • Xcode 12.0+
  • Swift 5.3+

Installation

  1. Clone the repository:

  2. Open the project in Xcode:

    • open ListView.xcodeproj

  3. Build and run the project on your preferred simulator or device.

Architecture

The project follows the MVVM architecture pattern:

  • Model: Represents the data and business logic. This includes CoreData entities and API data models.

  • View: SwiftUI views that display the data.

  • ViewModel: Manages the data for a view by interacting with the model and preparing the data for presentation in the view.
