iOS Handling a Notification

How do I get the notification to take me to the desire viewController?

Hey, I'm working on a project but struggling to get the notification to take me to my "NotiViewController". Sometimes it works as desired but other times it just opens my app to whatever viewController I was last on.

I hacked this code together from from Amit's video and some online sources:

extension QuestionViewController: UNUserNotificationCenterDelegate{
   func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: 
   UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> 
   Void) {
      let vc = storyboard?.instantiateViewController(withIdentifier: "NotiViewControllerID") 
      as! NotiViewController
      show(vc, sender: Any?.self)        
      completionHandler()
}

I want to be able to send a notification that asks the user a question, then once it is clicked have the user taken to a answer...

eg notificationQuestion: "How many states are in the contiguous United States?" =>tap notification => loads the appropriate NotiViewController: "48"

Ok, After moving a bit of code around I was able to solve this particular issue...

I noticed that the the desired viewcontroller would load only if the last viewcontroller loaded had the code: ` let notifictationCenter = UNUserNotificationCenter.current() notification.delegate = self

so the fix was to add that bit of code above and the extension to the other stubborn viewController and that did it... but I have another issue now...
