2. In your code, create a UNUserNotificationCenter object to manage and schedule notifications:

main.swift
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound]) { granted, error in
    if let error = error {
        // Handle the error
    } else {
        // Authorization granted

The above code requests authorization from the user to display banner notifications.

You can customize the title and body of the notification as per your requirements.

4. Create a UNNotificationRequest object to schedule the notification, specifying a trigger condition:

main.swift
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
let request = UNNotificationRequest(identifier: "Notification", content: content, trigger: trigger)
center.add(request)

In the above code, a time interval of 5 seconds is used as the trigger condition. You can use other trigger types such as location-based, calendar-based, or push notification-based as well.

5. Run the app and wait for the notification to be displayed on the banner of the device.

That's it! You have successfully generated a banner notification in Swift using the User Notifications framework provided by Apple.
