Hi, I would like to share an issue with the bottom accessory on iPhone Duo (iOS 27.1 beta 1). When the device is rotated from landscape to portrait and back to landscape, the bottom accessory shrinks and is no longer centered between the edge of the screen and the vertical tab bar. Steps to reproduce: Create UITabBarController with a regular UIView set as bottom accessory Open the app on iPhone Duo in unfolded landscape orientation Rotate the device to portrait and back to landscape The bottom accessory is smaller than prior to the orientation changes and isn’t centered between the edge of the device and the vertical tab bar anymore Set the accessory to nil and back to restore initial width Expected: Bottom accessory keeps its width across orientation changes Actual: Width of the bottom accessory changes after orientation changes (landscape -> portrait -> landscape). I’m using Xcode 27.1 beta and iOS 27.1 beta SDK (24A94403). I submitted a report via Feedback Assistant, here is the report ID: FB25002243. In the report I attached a minimal reproduction example and a video recording of the bug. Here is the minimal reproduction example: // SceneDelegate.swift import UIKit class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { guard let windowScene = (scene as? UIWindowScene) else { return } let window = UIWindow(windowScene: windowScene) window.rootViewController = TabBarControllerWithAccessory() window.makeKeyAndVisible() self.window = window } } // TabBarControllerWithAccessory.swift import UIKit class TabBarControllerWithAccessory: UITabBarController { override func viewDidLoad() { super.viewDidLoad() tabs = [ UITab(title: "First", image: UIImage(systemName: "1.circle"), identifier: "first") { _ in ScreenViewController() }, UITab(title: "Second", image: UIImage(systemName: "2.circle"), identifier: "second") { _ in ScreenViewController() }, ] bottomAccessory = UITabAccessory(contentView: AccessoryContentView()) } } class ScreenViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .systemBackground let mountButton = UIButton(configuration: .filled(), primaryAction: UIAction(title: "Mount") { [weak self] _ in self?.tabBarController?.bottomAccessory = UITabAccessory(contentView: AccessoryContentView()) }) let unmountButton = UIButton(configuration: .filled(), primaryAction: UIAction(title: "Unmount") { [weak self] _ in self?.tabBarController?.bottomAccessory = nil }) let stackView = UIStackView(arrangedSubviews: [mountButton, unmountButton]) stackView.axis = .vertical stackView.spacing = 16 stackView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(stackView) NSLayoutConstraint.activate([ stackView.centerXAnchor.constraint(equalTo: view.centerXAnchor), stackView.centerYAnchor.constraint(equalTo: view.centerYAnchor), ]) } } class AccessoryContentView: UIView { private let widthLabel = UILabel() override init(frame: CGRect) { super.init(frame: frame) backgroundColor = .systemOrange widthLabel.translatesAutoresizingMaskIntoConstraints = false addSubview(widthLabel) NSLayoutConstraint.activate([ widthLabel.centerXAnchor.constraint(equalTo: centerXAnchor), widthLabel.centerYAnchor.constraint(equalTo: centerYAnchor), ]) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func layoutSubviews() { super.layoutSubviews() let text = "\(bounds.width)" if widthLabel.text != text { widthLabel.text = text } } } Before: After: Thank you in advance!

Hi, I would like to share an issue with UITabBarController's vertical tab bar and iPhone Duo's unfolded pose. On iPhone Duo (27.2 beta 3), when tab bar controller is added to the view controller while in unfolded pose, the vertical tab bar doesn't appear unless the tab bar controller view's frame is set manually before adding it to the parent's view. Show any VC. Use unfolded Duo pose. After some time/on button press add a UITabBarController to it: (https://developer.apple.com/documentation/uikit/creating-a-custom-container-view-controller#Add-a-child-view-controller-programmatically-to-your-content) with Auto Layout constraints. Vertical tab bar does not appear. Fold and unfold the device. The tab bar appears. Expected: Tab bar appears after adding the UITabBarController in unfolded Duo pose. Actual: Tab bar does not appear after adding the UITabBarController in unfolded Duo pose. In Feedback Assistant report (FB25261013) I attached minimal reproduction example and recordings showing the different behavior in folded and unfolded poses and behavior with manual frame application fix (commented out in minimal reproduction example). Minimal reproduction example: // SceneDelegate.swift import UIKit class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { guard let windowScene = (scene as? UIWindowScene) else { return } window = UIWindow(windowScene: windowScene) window?.rootViewController = ViewController() window?.makeKeyAndVisible() } } // ViewController.swift import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .systemBackground let button = UIButton(configuration: .filled(), primaryAction: UIAction(title: "Show Tab Bar Controller") { [weak self] _ in self?.showTabBarController() }) button.translatesAutoresizingMaskIntoConstraints = false view.addSubview(button) NSLayoutConstraint.activate([ button.centerXAnchor.constraint(equalTo: view.centerXAnchor), button.centerYAnchor.constraint(equalTo: view.centerYAnchor), ]) } private func showTabBarController() { let tabBarController = UITabBarController() tabBarController.tabs = ["First", "Second", "Third"].map { title in UITab(title: title, image: UIImage(systemName: "circle"), identifier: title) { _ in let viewController = UIViewController() viewController.view.backgroundColor = .systemBackground return viewController } } addChild(tabBarController) // Uncomment to show the tab bar on the unfolded iPhone Duo. tabBarController.view.frame = view.bounds view.addSubview(tabBarController.view) tabBarController.view.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ tabBarController.view.topAnchor.constraint(equalTo: view.topAnchor), tabBarController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor), tabBarController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor), tabBarController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor), ]) tabBarController.didMove(toParent: self) } } Thank you in advance.

Hi, I would like to share an issue with UISearchBar's delegate method searchBarCancelButtonClicked on iOS 27 beta. On iOS 27 beta, when search bar is integrated into navigation bar’s items, tapping search cancel button doesn’t invoke UISearchBar’s delegate method searchBarCancelButtonClicked:. Steps to reproduce: Create UINavigationController with one UIViewController Set up searchController. Set searchController.searchBar.delegate, preferredSearchBarPlacement = .integratedButton, searchBarPlacementAllowsToolbarIntegration = false Tap the search button and type a query Tap the search cancel button Expected: On iOS 26, the searchBarCancelButtonClicked delegate method is called. Actual: On iOS 27 beta, the searchBarCancelButtonClicked delegate method is NOT called. On iOS 27 beta, if search bar is “stacked” or placed in the toolbar rather than the navigation bar, the bug does not reproduce. I’m using Xcode Version 27.0 beta 6 with latest available iOS 27 iPhone 17 Pro simulator (24A5423a). I reported the issue via Feedback Assistant with a minimal reproduction example and 2 videos comparing the behavior between iOS 26 and iOS 27 beta. Here is the report ID: FB24636315. Here is the minimal reproduction example: // SceneDelegate.swift import UIKit class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { guard let windowScene = scene as? UIWindowScene else { return } let window = UIWindow(windowScene: windowScene) window.rootViewController = UINavigationController(rootViewController: ViewController()) window.makeKeyAndVisible() self.window = window } } // ViewController.swift import UIKit final class ViewController: UITableViewController { private let allItems = (1...30).map { "Item \($0)" } private var items: [String] = [] private var cancelCount = 0 override func viewDidLoad() { super.viewDidLoad() items = allItems updateTitle() let searchController = UISearchController(searchResultsController: nil) searchController.searchBar.delegate = self navigationItem.searchController = searchController navigationItem.preferredSearchBarPlacement = .integratedButton navigationItem.searchBarPlacementAllowsToolbarIntegration = false tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell") } private func updateTitle() { title = "Cancel presses: \(cancelCount)" } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { items.count } override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) cell.contentConfiguration = { var config = cell.defaultContentConfiguration() config.text = items[indexPath.row] return config }() return cell } } extension ViewController: UISearchBarDelegate { func searchBarCancelButtonClicked(_ searchBar: UISearchBar) { print("searchBarCancelButtonClicked(_:)") cancelCount += 1 updateTitle() items = allItems tableView.reloadData() } } Thank you in advance!
