In my app I had created a initial vc, but I didn't really liked the design I've done so I changed it to a new one. Now the simulator is showing me the old design for a little while, and then it goes to the proper new one. How do I make the old one disappear? (I deleted the file of the old one )

I created this code that sends local notification after user reaches the view controller, but the notification is sent each time the user goes to the view controller. How do I make it send the notification only once? What change should I make in my code?
import UserNotifications
class firstViewController: UIViewController, UNUserNotificationCenterDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.badge,.sound,.alert]) { granted, error in
if error == nil {
print("User permission is granted : \(granted)")
}
}
// Step-2 Create the notification content
let content = UNMutableNotificationContent()
content.title = "Hello"
content.body = "Welcome"
// Step-3 Create the notification trigger
let date = Date().addingTimeInterval(2)
let dateComponent = Calendar.current.dateComponents([.year,.month,.day,.hour,.minute,.second], from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponent, repeats: false)
// Step-4 Create a request
let uuid = UUID().uuidString
let request = UNNotificationRequest(identifier: uuid, content: content, trigger: trigger)
// Step-5 Register with Notification Center
center.add(request) { error in
}
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.sound,.banner,.badge])
}
}

I wanted to submit my app to App Store so I signed up to Apple developer program and started filling up data in App Store connect. In the meantime I changed a few things in my app in Xcode and I'm curious if these changes had also been made in App Store connect.
In my app I've got moment where I use timer to go from one view controller to next view controller, and it doesn't work. Could somebody tell me what's wrong?
class fifthViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let delay : Double = 2.0 // 2 seconds here
DispatchQueue.main.asyncAfter(deadline: .now() + delay) {
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let IDKViewController = storyBoard.instantiateViewController(withIdentifier: "IDKview") as! IDKViewController
self.present(IDKViewController, animated:true, completion:nil)
}
}
}

In my app I have a black screen at one point and I want the user to know that it's not the end. I want to display text "tap to go next" on the bottom of the screen. To do that I'll need to use timer to show the text after couple of seconds. I don't know how to do it. Could anyone help?
