Technical Details

iOS Version and Framework: The app is built for iOS 15.2 and above using UIKit framework.
Architecture: VIPER (View, Interactor, Presenter, Entity, Router) architecture pattern is employed for organizing the codebase. This promotes separation of concerns and facilitates unit testing.
UI Layout: Compositional Layout is utilized for arranging UI elements, providing flexibility and efficiency in managing complex layouts.
Data Management:
- Singleton Class: A singleton class named "LocalData" is implemented for storing selected products and total bill locally. This ensures a single instance of the class throughout the app's lifecycle.
- Core Data Integration: Core Data is employed for saving and loading selected products and total bill state, ensuring persistence even when the app is closed or reopened.
Networking: Alamofire is used as the networking manager to handle API requests and responses efficiently. This abstracts away the complexities of network handling and provides a cleaner interface for API interactions.
Custom Cells:
- Product Cell: A custom cell used in both the listing and shopping cart screens to display product information.
- Selected Product Cell: Another custom cell exclusively used in the shopping cart screen to display selected products.
Protocol Implementation:
- ProductProtocol: Implemented to transform MainProduct and SuggestedProduct objects into a unified Product format. This abstraction allows for easier management and display of product data in the collection view cells.
Functionality:
- Persistence: The use of Core Data ensures that selected products and total bill are preserved across app sessions, preventing data loss.
- Lifecycle Management: The app utilizes lifecycle events such as closing and opening to trigger Core Data operations for saving and loading data, maintaining continuity in user experience.
