I am a novice in Swift. I have developed a small application with Xcode10. When I upgrade Xcode 10 to 11 version, all the views changed. Now, I see at the top of all views a small part of my first view (behind). When I scrolled down the view, I see my first view. It will more clear with the picture:

enter image description here

How can I do to avoid that?

    This is happening because you are presenting view controllers. Nothing wrong with the Xcode, it's due to iOS 13's new window approach. you can use following code to present full-screen presentation - `viewControler.modalPresentationStyle = .fullScreen` – Amir Khan Jun 15 '20 at 16:30
  • Thank you at first for your quick answer. Where I put this code? – Yvon Av Jun 15 '20 at 16:44
  • Based on your description, I assume you mean that the window changes appear only iOS 13 - Xcode 11 uses iOS13 in the simulator. If you have iOS devices running iOS 12 or earlier, they wouldn't have this new behavior. – benc Jun 15 '20 at 16:46
  • @YvonAv where depends if you are presenting it programmatically or using the storyboard https://www.appsdissected.com/wp-content/uploads/2019/08/Screen-Shot-2019-08-28-at-11.03.59.png – Leo Dabus Jun 15 '20 at 17:17
  • Thank you for your help. It' OK. I use storyborad – Yvon Av Jun 15 '20 at 18:42

This is the new behavior on iOS 13, you can use the snippet to change it back to full screen.

let vc = UIViewController()
vc.modalPresentationStyle = .fullScreen
self.present(vc, animated: true, completion: nil)

  • Thanks, but where I put this code ? In my first/maine swift ViewController or ? – Yvon Av Jun 15 '20 at 17:06
  • Yes, so you have to add it where the current viewController is presented, if possible you can also share your code in you question. – Rizwan Mehboob Jun 15 '20 at 17:08
  • import UIKit class FittingViewController: UIViewController{ // Declaration nom et icon TabBar required init?(coder aDecoder: NSCoder) { super.init(coder:aDecoder) tabBarItem=UITabBarItem(title: "Fittings", image: UIImage(named: "fitting-icon"), tag: 2) } override func viewDidLoad() { super.viewDidLoad() } override func viewWillDisappear(_ animated: Bool) { AppDelegate.AppUtility.lockOrientation(UIInterfaceOrientationMask.all) } } – Yvon Av Jun 15 '20 at 17:17
  • which ViewController is presenting FittingViewController? – Rizwan Mehboob Jun 15 '20 at 17:26
