MVVM Architecture: Ensures a clean separation of concerns, leading to maintainable and testable code.
Core Data: Provides robust and persistent data storage for your tasks.
Result Type for Error Handling: Employs the Result type for clean and consistent error management, using a custom enum for Core Data errors.
Context Merging: Demonstrates advanced Core Data techniques with context merging for efficient data handling.
NSFetchedResultsController: Powers the Statistics screen, efficiently fetching and managing completed task data.

Screen-Specific Highlights:

Main Screen (Task List):
- Dynamic UI Updates: Uses NotificationCenter observers to update the accent color and keyBoardObserver to manage the tab bar's visibility.
- Customizable Header: Features a custom toolBar (header view) with gesture and button handling.
- Interactive Task Management: Implements UITableViewDragDelegate and UITableViewDropDelegate for intuitive task reordering.
- Inline Editing: Allows direct task editing via a UITextField within the UITableViewCell.

- Scroll-Based UI Changes: Leverages the UIScrollViewDelegate to dynamically adjust the UI based on scroll position.
Settings Screen:
- Accent Color Customization: Provides a UICollectionView to select and persist the app's accent color using UserDefaults.
- Real-time UI Updates: Uses NotificationCenter to instantly reflect the chosen accent color throughout the app.
Statistics Screen:
- Data Visualization with Charts: Integrates the Charts framework (SwiftUI) to present completed task data in a visually engaging manner.
- Dynamic Table View: Adjusts the table view height dynamically based on content.
- SwiftUI State Management: Uses @Environment and @Published property wrappers for efficient data flow and UI updates.
Todo Detail Screen:
- Custom Presentation: Uses UIPresentationController and UIViewControllerTransitioningDelegate to display a concise pop-over view with task details.
