Template iOS App using Clean Architecture and MVVM

iOS Project implemented with Clean Layered Architecture and MVVM. (Can be used as Template project by replacing item name “Movie”). More information in medium post: Medium Post about Clean Architecture + MVVM

Layers

• Domain Layer = Entities + Use Cases + Repositories Interfaces
• Data Repositories Layer = Repositories Implementations + API (Network) + Persistence DB
• Presentation Layer (MVVM) = ViewModels + Views

Dependency Direction

Note: Domain Layer should not include anything from other layers(e.g Presentation — UIKit or SwiftUI or Data Layer — Mapping Codable)

Architecture concepts used here

• Clean Architecture https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html
• Advanced iOS App Architecture https://www.raywenderlich.com/8477-introducing-advanced-ios-app-architecture
• MVVM
• Data Binding using Observable without 3rd party libraries
• Dependency Injection
• SwiftUI and UKit view implementations by reusing same ViewModel (at least Xcode 11 required)
• CI Pipeline (Travis CI + Fastlane)

Includes

• Unit Tests for Use Cases(Domain Layer), ViewModels(Presentation Layer), NetworkService(Infrastructure Layer)
• UI test with XCUITests
• Size Classes in Detail view
• Dark Mode
• SwiftUI example, demostration that presentation layer does not change, only UI (at least Xcode 11 required)

Requirements

• Xcode Version 11.2.1+ Swift 5.0+

How to use app:

To search a movie, write a name of a movie inside searchbar and hit search button. There are two network calls: request movies and request poster images. Every successful search query is stored persistently.
