How do I preserve and restore state?

In Swift, preserving and restoring state is essential for providing a seamless user experience, especially when the app is closed or interrupted. To preserve state, you can use techniques such as saving data to UserDefaults or utilizing Codable to save objects. When restoring state, you retrieve the saved data and update your UI accordingly.
