Features

Launch Screen

• Launch screen with application name and icon.

Post List Screen

• ViewController with TableView: The primary screen displays a list of posts using UITableViewDiffableDataSource for seamless updates.
• Callbacks: Facilitates communication between the View and ViewModel through callbacks.
• Data Fetching: Upon screen load, the app uses URLSession to fetch data from a network, intelligently storing new posts into CoreData.
• Post Deletion Provide ability to delete posts from table view using swipe action and holding on post.
• Responsive UI: Fetched data is elegantly presented on the screen, ensuring a smooth and engaging user experience.

Add User Screen

• ViewController with TextField and TextView: The second screen empowers users to add new posts through intuitive text fields for title and body.
• Validation Rules: Title and body fields must not be empty; the app disables add button if validation fails.
• Go Back Action: If there is unsaved data, an alert prompts user to confirm whether user wants to navigate back to the post list screen.
• Duplicate Check: The app checks for duplicate post titles, alerting users if a post with the same title already exists.
