PushViewController() causes popover to be full screen - ios

Question

I want to push a popover on top of my view controller. Currently, this code resides in my subclass of UIView:
func presentGameOver() {
let transition: CATransition = CATransition()
transition.duration = 0.75
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.type = CATransitionType.fade
let currentController = (getCurrentViewController() as! UINavigationController).topViewController!
currentController.navigationController!.view.layer.add(transition, forKey: nil)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "GameOverViewController") as! GameOverViewController
vc.modalPresentationStyle = UIModalPresentationStyle.popover
vc.highScore = highScore
vc.score = score
vc.FONT_H = FONT_H
vc.delegate = self
currentController.navigationController?.pushViewController(vc, animated: false)
}
This is my class declaration:
class GridView: UIView, ModalHandler, UIPopoverPresentationControllerDelegate {
I have these two methods as well:
func popoverPresentationControllerShouldDismissPopover(_ popoverPresentationController: UIPopoverPresentationController) -> Bool {
return false
}
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return UIModalPresentationStyle.none
}
In the storyboard, for the view controller I want to be a popover, I set the content size(this and this).
However, when the popover is shown, it is shown full screen. When I previously used popovers, I would present them. Does popover display not work using pushViewController()?

The animation is quite complicated if you have little experience. The following code may give you some clues.
func presentGameOver() {
let transition: CATransition = CATransition()
transition.duration = 0.75
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.type = CATransitionType.fade
let currentController = (getCurrentViewController() as! UINavigationController).topViewController!
currentController.navigationController!.view.layer.add(transition, forKey: nil)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "GameOverViewController") as! GameOverViewController
vc.modalPresentationStyle = UIModalPresentationStyle.popover
vc.highScore = highScore
vc.score = score
vc.FONT_H = FONT_H
vc.delegate = self
if let popoverPresentationController = vc.popoverPresentationController{
popoverPresentationController.delegate = self;
popoverPresentationController.sourceView = self
popoverPresentationController.sourceRect = CGRect.init(x: 200, y: 200, width: 500, height: 300)}
currentController.present(vc, animated: false) {}
}
