SwiftUI Chapters Navigation App

A native iOS application demonstrating SwiftUI best practices, SOLID principles, and modern Apple frameworks through a chapter-based learning interface.

📱 Overview

This app provides a clean, navigable interface for exploring 19 SwiftUI chapters, from basic text handling to advanced animations and gestures. Built with the latest SwiftUI features and following industry best practices.

✨ Features

• Chapter List View: Scrollable list of all SwiftUI learning chapters
• Detail Navigation: Tap any chapter to view its detail screen
• SF Symbols Integration: Each chapter has a relevant SF Symbol icon
• Modern UI: Gradient-styled icons with clean, iOS-native design
• Type-Safe Navigation: Leveraging SwiftUI's NavigationStack

🏗️ Architecture

Design Patterns

• MVVM (Model-View-ViewModel): Clear separation of concerns
• Protocol-Oriented Programming: Flexible, testable data layer
• Dependency Injection: Loose coupling between components

SOLID Principles

✅ Single Responsibility Principle

• Each component has one well-defined purpose
• ChapterDataProvider handles data retrieval
• ChaptersViewModel manages business logic
• Views focus solely on UI presentation

✅ Open/Closed Principle

• Protocol-based ChapterDataProviding allows extension without modification
• New data sources can be added by conforming to the protocol

✅ Liskov Substitution Principle

• Any ChapterDataProviding implementation can replace another

✅ Interface Segregation Principle

• Focused protocols with minimal required methods

✅ Dependency Inversion Principle

• ViewModel depends on ChapterDataProviding protocol, not concrete implementation
