How to present a popup view in full screen - ios

Question

I've following view configuration
Tab bar -> Nav controller -> View: Click on a button -> segue to-> Another view: Click on a button -> Popup view.
This modal view is on a different storyboard.
I want to present this model view in full screen. I've tried this solution mentioned on Presenting modal in iOS 13 fullscreen but it doesn't work. I've also tried few other solutions but the popup view is not showing over full screen, status bar is visible at the top.
How do I present modal view in a full screen?
let storyboard = UIStoryboard(name: "Other", bundle: Bundle.main)
guard let popupVC = storyboard.instantiateViewController(withIdentifier: "PopUpViewController") as? PopUpViewController else {
print("PopUpViewController not found")
return
}
popupVC.modalPresentationStyle = .fullScreen
self.present(popupVC, animated: true, completion: nil)

Answer 1

You could try presenting with the navigation controller.
let storyboard = UIStoryboard(name: "Other", bundle: Bundle.main)
guard let popupVC = storyboard.instantiateViewController(withIdentifier: "PopUpViewController") as? PopUpViewController else {
print("PopUpViewController not found")
return
}
var navigationController = UINavigationController(rootViewController: popupVC)
navigationController.modalPresentationStyle = .fullScreen
self.present(navigationViewController, animated: true, completion: nil)
An alternative would be to use presentViewController but presentViewController will only present one viewController modally over the currently visible viewController whereas presenting with the navigationController will give the flexibility to push further components on top, providing a smoother navigation experience with go back to previous page kind of behaviour.

Maybe try creating the view controller this way:
let popOverVC = UIStoryboard(name: "yourBoard", bundle: nil).instantiateViewController(withIdentifier: "YourViewController") as! YourViewController
self.addChild(popOverVC)
let lSs = UIScreen.main.bounds
popOverVC.view.frame = CGRect(x: 0, y: 0, width: lSs.width, height: lSs.height)
popOverVC.view.tag = tag
self.view.addSubview(popOverVC.view)
popOverVC.didMove(toParent: self)
Within the popup view controller class, add a method for animating its view in viewDidLoad.
Edit: I read your replies. The issue you are having is caused by not handling the status bar properly. Instead of trying to make this veiewcontroller fullscreen, simply hide the status bar

and bring it back when you want to see it again.
