Architecture

MVVM (Model-View-ViewModel) pattern combined with a Repository Pattern

Layers

1. Presentation Layer (SwiftUI + MVVM):

   • Views: SwiftUI views that observe the ViewModel for state changes.
   • ViewModels: Responsible for UI logic, data transformation, and handling user input.

2. Data Layer (Repository & Network):

   • Repository: Acts as a single source of truth to fetch data from the network
   • API Client: Handles API requests using URLSession and JSONDecoder to decodes JSON responses.
