Replace the viewcontroller without it appearing behind it

Question

My issue occurs when changing the VC, the old VC continues to appear in the background (see screen capture). How can I fix it?

Thank you for your help.

Answer 1

The sheet presentation style appears as a card. To make it fullscreen use this.

let vc = UIViewController()
vc.modalPresentationStyle = .fullScreen //or .overFullScreen for transparency
self.present(vc, animated: true, completion: nil)

Answer 2

If VC is to disappear, try to get rid of its reference - call the destructor - deinit, and then VC will be destroyed by ARC
