Template iOS App using Clean Architecture and MVVM with Views written in Code

iOS Project implemented with Clean Layered Architecture and MVVM. (Can be used as Template project by replacing item name “Repository”). 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)

Includes
