Swift Piscine Projects

This repository showcases a collection of iOS applications built with SwiftUI, demonstrating a progression from basic UI layout to complex networking and authentication. The focus is on clean architecture, modern concurrency patterns, and third-party integrations.

1. Calculator (Logic & MVVM)

Project: calculator_app

A functional calculator app built to demonstrate strict separation of concerns.

• Architecture: Uses MVVM (Model-View-ViewModel) to decouple the calculation logic from the view layer.
• UI Construction: Layout built with nested HStack and VStack components.
• State Management: Utilizes @Published properties for reactive UI updates.

2. Weather App (Networking & Concurrency)

Project: medium_weather_app / advanced_weather_app

A location-based weather application that fetches real-time data.

• Networking: Implements Async/Await for non-blocking API requests to OpenMeteo.
• Data Parsing: Uses Codable structs to safely parse JSON responses.
• Location Services: Integrates CoreLocation to access device GPS coordinates and handle permission flows.

3. Diary App (Auth & Persistence)

Project: diary_app

A secure notes application featuring user accounts and cloud integration.

• Authentication: Implements Firebase Auth with OAuth providers (Google & GitHub).
• Reactive Flow: Uses Combine listeners to manage authentication state and route users.
• Storage: Securely manages user sessions and data persistence.
