Headlines

Headlines is an iOS app built 95% in SwiftUI and 5% UIKit. It uses Combine, Apple's solution to reactive programming, to handle asynchronous operations. The MVVM architecture has been implemented with a one and only view model conforming to the @ObservableObject protocol which will be observed by our views. Any changes in the model will be known to the view model and be reflected on the UI.

UI

• Headlines is built 95% in SwiftUI using all the built-in components the system provide such as VStack, HStack, Stack, Picker, List.
• It includes a UIKit component, a UICollectionView, which conforms to the UIViewRepresentable protocol, Apple’s built-in solution to integrate UIKit components into SwiftUI.

Networking

• Network request have been implemented using Combine, Apple's new framework to handle asynchronous events by combining event-processing operators.

Design pattern

• The app is built using an MVVM architecture which is a perfect fit for SwiftUI as we can make our view model conform the ObservableObject and mark its underlying properties as @Published so that our views always reflect the latest model changes.

Platforms

• Headlines runs on iPhone.
