It's fixed in iOS 18 Beta 5.

It seems to me that, no matter which of the two variants posted above I'm using, the very first presentation does not look smooth. On the very first presentation I briefly get a white screen (when using the empty UIView) or a transparent screen (when using controller.view) before the presentation.

Also, I do not really understand why this solution is working at all? Why does implementing that delegate call enable the swipe down to dismiss? Did you find it out by accident?

I do have the same issue, UIRequiresFullScreen does not seem to be working any more. Also adding UIDesignRequiresCompatibility does not help with that. I understand that many apps are great when supporting all orientations and sizes, but there are also legitimate specific use cases where fullscreen portrait only is all that is needed and wanted.

Specifically, I also wonder how games are supposed to handle this?

I get an error when trying to update the post, therefore I add it as a new comment: The toolbar is showing up on iPadOS 26.

This is what it looks like in iOS 26 beta 4. The toolbar is behind the tabbar: All I did in this demo project is embed the default view controller in a navigation controller and then embed that in a tabbar. Here's the view controllers code: override func viewDidLoad() { super.viewDidLoad() title = "Hello World" let actionButton = UIBarButtonItem(title: "This is a button on the toolbar", style: .plain, target: self, action: #selector(buttonTapped)) self.navigationController?.isToolbarHidden = false self.toolbarItems = [actionButton]; }

Yes, I can confirm that - I've tried it with all the current versions. Unfortunately I haven't found a good workaround for this issue yet.

I solved it using this workaround: override func scrollViewDidScroll(_ scrollView: UIScrollView) { guard let tableView = scrollView as? UITableView else { return } for cell in tableView.visibleCells { let rect = tableView.convert(cell.frame, to: tableView) if rect.origin.y <= tableView.contentOffset.y { cell.isHidden = true } else { cell.isHidden = false } } }
