Answer 1

You many have to schedule local notification which is now available in UNUserNotificationCenter.

So,

1. For Scheduling a Notification Locally from Your App, follow this doc.
2. For Handling Notifications and Notification-Related Actions, follow this doc.

To Handle Notifications in your AppDelegate or where you want to handle UNUserNotificationCenter delegate method, add below code:

class AppDelegate:NSObject, UIApplicationDelegate, UNUserNotificationCenterDelegate{

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {


    let center = UNUserNotificationCenter.current()
    center.delegate = self // Don't forgot to set delegate

    //To get permissions from user:
    let options: UNAuthorizationOptions = [.alert, .sound, .badge];
    center.requestAuthorization(options: options) {
        (granted, error) in
        if !granted {
            print("Something went wrong")
        }
    }

    return true
}
}

Answer 2

1. You can use local notifications for getting an alarm notifications.

2. You can handle the click in the delegate method of UNUserNotificationCenterDelegate and navigate to the desired page.

   func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 
   

3. For displaying notification when app is in foreground use this method from same delegate

       func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
