If you access the presentationController property before setting the modalPresentationStyle, the style is ignored. This code will result in a full screen modal presentation, as expected: let viewController = UIViewController() viewController.modalPresentationStyle = .fullScreen _ = viewController.presentationController present(viewController, animated: true) This code will result in a page sheet modal presentation, which is not expected: let viewController = UIViewController() _ = viewController.presentationController viewController.modalPresentationStyle = .fullScreen present(viewController, animated: true) I would expect to be able to access the presentationController property at any point and it not to affect the modalPresentationStyle value. This resulted in a day of dev time lost to trying to figure out why the modal style was not being applied! I have attached a minimal project to display this behaviour. This was observed on Xcode 11.3.1, with iOS 13.3 simulator.
