How can I add a title to an iOS push notification?

I send push notifications to my client application with a cloud script and on Android the notification looks like this:

Welcome message

Hello

I want to show the notification identically on iOS, but on my iOS device it looks like this:

Hello

Hello

How can I show the correct title("Welcome message") in my push notification on iOS?

UPDATE: I found out that my message title("Welcome message") is not in userInfo, just the message body("Hello"). Why is the message title("Welcome message")not included in userInfo?

enter image description here

public override void ReceivedRemoteNotification(UIApplication application, NSDictionary userInfo) {
    ProcessNotification(userInfo, false);
}
void ProcessNotification(NSDictionary options, bool fromFinishedLaunching) {
    // Check to see if the dictionary has the aps key.  This is the notification payload you would have sent
    if (null != options && options.ContainsKey(new NSString("aps"))) {
        //Get the aps dictionary
        NSDictionary aps = options.ObjectForKey(new NSString("aps")) as NSDictionary;

        string alert = string.Empty;

        if (aps.ContainsKey(new NSString("alert"))) alert = (aps[new NSString("alert")] as NSString).ToString();

        if (!fromFinishedLaunching) {
            //Manually show an alert
            if (!string.IsNullOrEmpty(alert)) {
                NSString alertKey = new NSString("alert");
                UILocalNotification notification = new UILocalNotification();
                notification.FireDate = NSDate.FromTimeIntervalSinceNow(10);
                notification.AlertTitle = aps.ObjectForKey(alertKey) as NSString;
                notification.AlertBody = aps.ObjectForKey(alertKey) as NSString;
                notification.TimeZone = NSTimeZone.DefaultTimeZone;
                notification.SoundName = UILocalNotification.DefaultSoundName;
                UIApplication.SharedApplication.ScheduleLocalNotification(notification);
            }
        }
    }
}

The key "alert" in your push payload is read by the OS as the title of the notification. If you want to show any custom title to your notification there are a few possible ways

Easy Way

Change the value of payload key "alert" to the your custom message.

Hard Way

Create Notification service extension.

It’s a small chunk of code that is run just before the phone shows a notification you’ve sent, and it lets you customise the content of that notification before the user ever sees it

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request
           withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler;

- (void)serviceExtensionTimeWillExpire;


class NotificationService: UNNotificationServiceExtension {
var contentHandler: ((UNNotificationContent) -> Void)?
var bestAttemptContent: UNMutableNotificationContent?

override func didReceive(
    _ request: UNNotificationRequest,
    withContentHandler contentHandler:
        @escaping (UNNotificationContent) -> Void)
{

    print (request.content.userInfo)
    self.bestAttemptContent = request.content
    //We can now change title 
    self.bestAttemptContent.title = "Welcome message"
    contentHandler (self.bestAttemptContent)
    return
}}

NOTE : you need to have the key "mutable_content" and value 1 in your payload

"aps" : {
    "alert" : "Welcome Message"
    "badge" : 5
    "muatble_content" : 1
},
