NewsArticle

Requirements:

• iOS 13.0+
• Xcode 11.6
• Swift 5.2

Objective:

This sample app to demonstrate some aspect of clean architecture using MVVM pattern, RxSwift, dependency injection, SOLID principles , loose coupling, unit testing, Dark mode support and some of the best practices used in modern iOS programming using Swift.

App Goal:

• This project was intended to work as a News List demo projects for iOS using Swift.
• The demo uses the News API which returns information in a JSON format.
• Use of UITableViewController to display News list information.
• Implemented Unit test for business logic.
• Use of RxSwift for Reactive programming.

Installation

• Xcode 11.6(required)
• Clean /DerivedData folder if any
• Run the pod install pod install
• Run Cuckoo script to Mock your Swift objects ./Cuckoo-GeneratedMocks.sh
• Run SwiftGen script to generator Swift code for assets, Localizable.strings etc ./generate-swiftgen.sh
• Then clean and build the project in Xcode

3rd Party Libraries

• RxSwift - ReactiveX/RxSwift is used to make Reactive binding of API call and response

• Kingfisher - onevcat/Kingfisher for downloading and caching images from the web.

• PKHUD - pkluz/PKHUD to show loading activity indicator

• SwiftRichString - malcommac/SwiftRichString Elegant, easy and Swifty way to create Attributed Strings

• SwiftLint - realm/SwiftLint A tool to enforce Swift style and conventions.

• SwiftGen - SwiftGen/SwiftGen swift code generator for your assets, storyboards, Localizable.strings.

• Pecker - woshiccm/Pecker CodePecker is a tool to detect unused Swift code.

• Quick - Quick/Quick is testing framework in swift

• Nimble - Quick/Nimble is Matcher Framework for Swift to pair with Quick

• Cuckoo - Brightify/Cuckoo is tasty mocking framework for unit tests in swift

Technical notes:

• MVVM - My preferred architecture.
  • MVVM stands for “Model View ViewModel”
  • It’s a software architecture often used by Apple developers to replace MVC. Model-View-ViewModel (MVVM) is a structural design pattern that separates objects into three distinct groups:
• Models hold application data. They’re usually structs or simple classes.
• Views display visual elements and controls on the screen. They’re typically - subclasses of UIView.
• View models transform model information into values that can be displayed on a view. They’re usually classes, so they can be passed around as references.
