NewsReader

An iOS UIKit prototype of an online News Reader.

Features

Get Started

• Xcode 14.1 (Xcode 13.x not available due to developer's macOS version requirement).
• Open the NewsReader.xcodeproj and start building.
• Swift Package Manager is used as the dependency manager of choice, so no further installation steps required.
• Unit tests are included as part of the main NewsReader scheme.
• For UI tests, switch to NewsReaderUITests scheme to trigger.

Architecture

There are 2 main layers of the application:

• Presentation layer for controlling the UI, MVVM is used with closure callbacks for data binding due to its simplicity. For more complex data binding mangements a Functional Reactive Programming framework should be used e.g. Combine, RxSwift, ReactiveSwift etc.
• Data layer for handling API requests and local storages, all calls to data providers (URLSession, UserDefaults etc.) are wrapped inside protocols to utilise dependency injection for testing purpose.

3rd party libraries

• Kingfisher for asynchronous image loading & caching.
• Ambassador for stubbing network requests in UI tests.

Notes

• All screens are sharing a single Main.storyboard file, can split out into separate storyboards for better management.
• Navigation are performed directly inside view controllers, coordinator/router pattern can be utilised to improve reusability and testability of navigations.
• Timestamp values from the JSON are parsed as Int, property wrappers can be implemented to automate the parsing of this value into Date type for more usability client side.
• Article Details screen has no view model due to its simplicity, can introduce as more requirements arise.
