Why is it important to handle push notifications in the AppDelegate?

Handling push notifications in the AppDelegate is crucial primarily to ensure notifications are properly received and displayed. The AppDelegate serves as the central hub for app-level events, including the receipt of remote notifications. When a push notification is sent to the device, the system calls specific methods in the AppDelegate, providing an opportunity to manage the notification's presentation and how users interact with it.

By implementing the appropriate methods within the AppDelegate, developers can configure notifications to display alerts, badges, or sounds based on the app's state (foreground or background) and manage how the app responds when the user interacts with a notification. This is essential for maintaining a seamless user experience and ensuring that users are informed of important updates or messages from the app.

Handling notifications in this way is vital not just for functionality but also for user engagement, as it allows the app to communicate effectively with users, prompting them to take action or return to the app when necessary.
