User Profile

I tried to create the demo with the code import UIKit class ViewController: UIDocumentBrowserViewController, UIDocumentBrowserViewControllerDelegate { override func viewDidLoad() { super.viewDidLoad() self.browserUserInterfaceStyle = .dark let button = UIBarButtonItem(title: "First", style: .plain, target: nil, action: #selector(action(_:))) let button2 = UIBarButtonItem(title: "Second", style: .plain, target: nil, action: #selector(action(_:))) self.additionalLeadingNavigationBarButtonItems = [button, button2] } @objc func action(_ sender: UIBarButtonItem) { showAlert(with: sender) } func showAlert(with button: UIBarButtonItem) { let controller = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet) let action = UIAlertAction(title: "Test", style: .default) controller.addAction(action) controller.addAction(action) let presentationPopover = controller.popoverPresentationController presentationPopover?.sourceItem = button present(controller, animated: true) } } But the action sheet is in the wrong position when the user taps the button bar. This issue only happens when the user switches between the share and recent options before tapping the bar button.
