How to change iOS notification message upon receiving?

When I push notification from OneSignal, I want to push something like

", you have received a message"

I want to replace $name in app with the username something like

notificationMessage = UserDefaults.standard.string(forKey: "username") + notificationMessage

Is it possible to override notification?

If you mean to change the alert that the System shows, then NO you can't change those. They are managed by the OS.

For foreground only:

If you have some internal alert that you'd like to pop—when the app is in foreground then you're free to do as you wish

For example you could do something like:

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

    //1. extract notification data
    let message = notification.request.content.body
    let title = notification.request.content.title


    // 2. use the message and title and change their values
    // 3. use your new message and title and show your own custom alert. 


    // 4. I excluded the alert so you could show whatever you like yourself. But still I want to increase the badge and have sound when notification arrives...
    completionHandler([.badge, .sound])
}

you can't change the request itself since it's a get only...

Having that said I don't suggest this. Your logic of this should be handled on the server you push these notifications. This should be unnecessary.
