It also incorporates powerful frameworks like SPLarkController and Charts to provide advanced features and visualizations.

Features

Task Flow is packed with features designed for efficiency and a delightful user experience. Here's a breakdown of the key components and technologies used:

Core Functionality & Architecture:

• Hybrid UI (UIKit & SwiftUI): Combines the strengths of both frameworks for optimal performance and flexibility.
• 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.
  • Smooth Animations: Employs CAShapeLayer for visually appealing checkmark animations.
  • Efficient Data Display: Utilizes UITableViewDiffableDataSource with snapshots for optimized table view updates.
  • 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.

Additional Features:

• feedBackService: Provides haptic feedback (vibration) for a more tactile user experience.
