ToDo App

A modern iOS task management application built with Swift, featuring a sophisticated theme management system and clean architecture. This project marks my first experience with SwiftUI and modern iOS development practices.

Features

Core Architecture & Technologies

• MVVM Architecture: Clean separation of concerns with ViewModels handling business logic and Views focusing on UI presentation
• Core Data: Robust data persistence layer for task management
• Scene-Based Architecture: Modern iOS app structure utilizing UIWindowScene for better window management
• Theme Management System: Advanced theme switching capabilities with system-wide application
• SwiftUI Integration: First experience with SwiftUI, combining it with UIKit for enhanced UI development
• Charts Framework: Integration of the popular Charts library for data visualization

Theme Management System

The app features a sophisticated theme management system implemented through ThemeManager:

• Singleton Pattern: Global access to theme settings through ThemeManager.shared
• Scene-Based Theme Application: Utilizes UIApplication.shared.connectedScenes to apply themes across all windows
• Persistent Theme Storage: Theme preferences are stored in UserDefaults for persistence
• Dynamic Theme Switching: Real-time theme updates across all app windows
• System Integration: Seamless integration with iOS system appearance settings

Screen-Specific Features

Main Screen

• Dynamic task list with Core Data integration
• Smooth animations and transitions
• Custom UI components for enhanced user experience

Settings Screen

• Theme customization options
• System-wide theme persistence
• Real-time theme preview

Archive Screen

• Historical task management
• Efficient data retrieval and display
• Custom sorting and filtering options

SwiftUI & Charts Implementation

The app incorporates modern iOS development practices:

• Hybrid UI Approach: Combining UIKit and SwiftUI for optimal performance and flexibility
• Charts Integration:
  • Beautiful data visualization using the Charts framework
  • Custom chart configurations for task statistics
  • Interactive chart elements with user feedback
  • Dynamic data updates and animations
• SwiftUI Learning Journey:
  • First experience with declarative UI programming
  • Implementation of SwiftUI views alongside UIKit components
  • State management using SwiftUI's property wrappers
  • Custom SwiftUI components development

Technical Highlights

• Scene-Based Window Management: Advanced understanding of iOS window and scene hierarchy
• Custom View Components: Reusable UI elements for consistent design
• Protocol-Oriented Programming: Clean interfaces for component communication
• Extension-Based Utilities: Swift extensions for enhanced functionality
• Observer Pattern: Efficient state management and UI updates
• Modern UI Development: First-hand experience with SwiftUI and Charts framework
• Data Visualization: Professional-grade charts and graphs for task statistics

Architecture

The app follows a well-structured architecture:
