After upgrading the Xcode to version 11, the App developed for Ipad does not behave in a maximized way on the screen when running, both in the simulator and on the device, but the storyboard is perfect.

No Xcode: No Xcode:

In the Simulator or Ipad: No Simulador

swift xcode

  • It displays the screen as a modal? take a test, run the app, see if you can drag down that modal and if it closes the screen.

  • If you drag down this "modal" screen, it is just this blue screen of the background. As amazing as it looks the same app opens perfectly in Xcode ver.10

  • This happens because Apple changed the modalpresentation in iOS13, it is not an Xcode problem. Need to change it from Automatic q is the default in iOS 13 to fullscreen.

  • It worked out really well

  • Before: -------- Let storyboard = Uistoryboard(name: "Main", Bundle: nil) Let vc = storyboard.instantiateViewController(withIdentifier: "navController") as Uiviewcontroller self(vc, Animated: true, present: nil) --------- After: --------- Let storyboard = Uistoryboard(name: "Main", Bundle: nil) Let vc = storyboard.instantiateViewController(withIdentifier: "navController") as Uiviewcontroller vc.modalPresentationStyle = . fullscreen self.present(vc, Animated: true, Completion: nil) ---------

The screen displayed as a modal (sheet) is not a problem of Xcode 11, this behavior happens from iOS 13 and derivatives (iPadOS) as announced in WWDC’s talk of 2019 Modernizing Your UI for iOS 13, starts at 09:45 lasts a little more than 10 minutes.

What changed was the property modalPresentationStyle has assumed the default value .automatic this displays the viewcontroller as a modal and also adds a close Gesture that is triggered by clicking and dragging down the screen.

Resolution with storyboard/following

Access the storyboard, select the following and in the inspector attribute (blue icon at the top), change the properties:

  • kind of push for Present Modally
  • Presentation of Same As Destination for Full Screen

Programmatic resolution

1) To let the screen fullscreen as in iOS 12 just set modalPresentationStyle as .fullScreen in the viewcontroller that will be displayed.

@IBAction func mainClick(_ sender: Any) {
    if let controller = self.storyboard?.instantiateViewController(withIdentifier: "DetailsViewController") {
        controller.modalPresentationStyle = .fullScreen
        present(controller, animated: true)
    }
}

2) You can get around the situation by avoiding the Gesture that hides the view controller by setting isModalInPresentation as true, the screen will still have visual of a tab.

@IBAction func mainClick(_ sender: Any) {
    if let controller = self.storyboard?.instantiateViewController(withIdentifier: "DetailsViewController") {
        controller.isModalInPresentation = true
        present(controller, animated: true)
    }
}

Delegates

Three new methods are offered to handle this new Esture through UIAdaptivePresentationControllerDelegate.

  • presentationControllerDidAttemptToDismiss: Activated by pulling the tab only when isModalInPresentation for true.

  • presentationControllerDidDismiss: Activated when the tab has already disappeared and isModalInPresentation for false.

  • presentationControllerWillDismiss: Activated when starting Esture (click and drag) and isModalInPresentation for false.

Example:

import UIKit

class DetailsViewController: UIViewController {


    override func viewDidLoad() {
        super.viewDidLoad()
        self.presentationController?.delegate = self
        self.isModalInPresentation = false
    }
}

extension DetailsViewController: UIAdaptivePresentationControllerDelegate {
    func presentationControllerDidAttemptToDismiss(_ presentationController: UIPresentationController) {
        print("Ao puxar a aba")
    }

    func presentationControllerDidDismiss(_ presentationController: UIPresentationController) {
        print("Quando a aba já sumiu")
    }

    func presentationControllerWillDismiss(_ presentationController: UIPresentationController) {
        print("No inicio do gesture")
    }
}
