@Uma Madhavi Try adding below method

SWIFT

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

Objective-C

 - (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
completionHandler(UNNotificationPresentationOptionAlert);

}

Since you requested me on another thread's comment section, I am posting this working set of code with the same configuration you have mentioned:

import UserNotifications

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate,CLLocationManagerDelegate, UNUserNotificationCenterDelegate {
    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        //############## FIREBASE ##################

        registerForPushNotifications(application)
        FIRApp.configure()
        // Add observer for InstanceID token refresh callback.
        NSNotificationCenter
            .defaultCenter()
            .addObserver(self, selector: #selector(AppDelegate.tokenRefreshNotification),
                         name: kFIRInstanceIDTokenRefreshNotification, object: nil)

        //############ FIREBASE END ################  

        return true
    }

    func registerForPushNotifications(application: UIApplication) {

        if #available(iOS 10.0, *){
            UNUserNotificationCenter.currentNotificationCenter().delegate = self
            UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert], completionHandler: {(granted, error) in
                if (granted)
                {
                    UIApplication.sharedApplication().registerForRemoteNotifications()
                }
                else{
                    //Do stuff if unsuccessful...
                }
            })
        }

        else{ //If user is not on iOS 10 use the old methods we've been using
