Hi, I'm updating my iPhone app (iPhone only) to be ready with iOS 26. I'm building my app using Xcode 26.0 beta 6 (17A5305f) and testing it on an iPad running iPadOS 26 (23A5326a). I found an issue with my new app icon updated using Icon Composer and I was able to find the issue. An iPhone only app running on iPadOS 26 doesn't use the provided app icon. It always displays the "standard" light icon. I just added iPad in Supported Destinations and the app icon now respect light/dark/translucent/tinted modes on the Home Screen. I submitted feedback FB19768667

Hi all, Recently, I received feedback from users that the cell of UITableView will be enlarged when clicked on the iOS26 system. After positioning, it was found that the iOS26 system has reset the frame of the contentView so that its width is always the screen width. The following Demo can reproduce this problem. Does anyone have this problem? Is there a solution? Thanks Run and click on the cell to see the problem http://www.yangshuang.net/TestProject.zip

An iOS app has a UINavigationController with a UINavigationBar that is non-translucent (e.g. black). When performing a push (or pop) to navigate to or from another UIViewController the UIBarButtonItems on the navigation bar are flashing a white background. With a dark navigation bar this is very noticeable and not desirable. This only occurs when run on iOS 26 and is related to Liquid Glass I've created FB19660024 with a minimal Xcode workspace to reproduce, along with a video showing the behavior. This is a cosmetic bug, not affecting functionality, but is a very undesirable effect on apps with dark and non-translucent navigation bars. Has anyone else seen this and found a workaround?

I was excited about the new APIs added to Network.framework in iOS 26 that offer structure concurrency support out of the box and a more modern API design in general. However I have been unable to use them to create a device-to-device QUIC connection. The blocker I ran into is that NetworkListener's run method requires the network protocol to conform to OneToOneProtocol, whereas QUIC conforms to MultiplexProtocol. And there doesn't seem to be any way to accept an incoming MultiplexProtocol connection? Nor does it seem possible to turn a UDP connection into a QUIC connection using NetworkConnection.prependProtocols() as that also only works for network protocols conforming to OneToOneProtocol. I suspect this is an accidental omission in the API design (?), and already filed a Feedback (FB18620438). But maybe I am missing something and there is a workaround or a different way to listen for incoming QUIC connections using the new NetworkListener? QUIC.TLS has methods peerAuthenticationRequired(Bool) and peerAuthenticationOptional(Bool), which makes me think that peer to peer QUIC connections are intended to be supported? I would also love to see documentation for those methods. For example I wonder what exact effect peerAuthenticationRequired(false) and peerAuthenticationOptional(false) would have and how they differ.

An app built on Xcode 26 (beta4) presents various UIViewCOntrollers. Presentation of any UIViewController that contains a UIToolbar leads to a UIKit crash when run on an iOS 18.5 device, it does not crash when run on iOS 26. The exception logged: *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView because no class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)' Anyone else seen this? I've submitted a bug report via Feedback Assistant, including a minimal Xcode workspace that reproduces the crash, hoping this will get some attention.

It seems that beta 3 broke StoreKit Testing when running against an iOS 26 simulator device. Specifically, when validating product IDs, the debug console displays messages like the following: [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) In addition, the SKProductsResponse (I am using the original StoreKit API), lists all requested product IDs in invalidProductIdentifiers. The products array is empty. StoreKit Testing behaves as expected when Xcode 26 beta 3 is run against an iOS 18.4 simulator device.

A bottom accessory view is set on the UITabBarController. When changing the window size either by dragging the resizing grip or when going to portrait mode, the accessory view shrinks down to the smaller width. When resizing the window to make it larger, the accessory view doesn’t resize to the full available width. During a workshop setup by Apple, folks from Apple told me that the view set as the content view of the UITabAccessory should not have its frame changed, either by using Auto Layout or by setting the frame. It seems logical since the view in the bottom accessory is supposed to resize accordingly to several factors, like when going inline inside the tab bar. Am I missing something? Maybe there is additional setup required not mentioned in the dedicated video. Feedback is FB19017330. It contains a sample project and videos demonstrating the issue. Reproduced on Xcode 26 beta 6 (17A5305f) I copy and paste the sample code that setups the bottom accessory for good measure. final class MiniPlayer: UIView { let label = UILabel() override init(frame: CGRect) { super.init(frame: frame) label.text = "Mini Player" label.numberOfLines = 0 label.textAlignment = .center addSubview(label) label.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ label.centerXAnchor.constraint(equalTo: centerXAnchor), label.centerYAnchor.constraint(equalTo: centerYAnchor) ]) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } } // MARK: - View Controller class ViewController: UIViewController { let rootTabBarController = UITabBarController() let miniPlayer = MiniPlayer() override func viewDidLoad() { super.viewDidLoad() let items: [UITab] = [ UITab(title: "Tab 1", image: UIImage(systemName: "archivebox.fill"), identifier: "tab-1") { _ in UIViewController() }, UITab(title: "Tab 2", image: UIImage(systemName: "books.vertical.fill"), identifier: "tab-2") { _ in UIViewController() }, UISearchTab { _ in UIViewController() } ] rootTabBarController.tabs = items rootTabBarController.view.backgroundColor = .secondarySystemBackground view.addSubview(rootTabBarController.view) rootTabBarController.view.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ rootTabBarController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor), rootTabBarController.view.topAnchor.constraint(equalTo: view.topAnchor), rootTabBarController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor), rootTabBarController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor) ]) rootTabBarController.bottomAccessory = UITabAccessory(contentView: miniPlayer) } }

Please refer to Feedback report: FB19701007 The Personal Voice file created in English changes to either Spanish or Chinese and no longer works properly. This has been happening since Beta 1 of iOS/iPadOS 26. I have been unable to pinpoint what causes this to occur. Possibly downloading foreign voices to a device or using different voices via AVSpeechSynthesizer. I run an app in Xcode on my device that prints to the console info about the installed voices. Initially after creation here is the output: Voice Identifier: com.apple.speech.personalvoice.16173F8D-DFB0-4024-98CC-69D965FD96A4 Language: en-US Then I hear a Spanish accent and find this: Voice Identifier: com.apple.speech.personalvoice.16173F8D-DFB0-4024-98CC-69D965FD96A4 Language: es-MX Currently it isn't working and here is the output: Voice Identifier: com.apple.speech.personalvoice.16173F8D-DFB0-4024-98CC-69D965FD96A4 Language: zh-CN Note that the voice file on all three above is the same. No matter what the user does, the created voice file should never be able to change languages. On my test devices I reset them all by erasing all content and settings and creating a new English Personal Voice and the issue persists. A side issue is the toggle share across devices doesn't remain off if turned off. I tried to not share to see if that could be the cause, but the toggle turns on automatically. It won’t remain off.

Hi! I am very new to the apple ecosystem. I saw a lot of comments online about how Stage Manager enabled iPads have access to extending the screen to an external display, and that was what hyped me about this beta. Unfortunately, while i do have Stage Manager now, the display is still unwilling to be extended. Is that a feature that’s planned to be included in the OS? Or am i just out of luck? The ipad is one of the most capable devices i have so i was kind of hoping it would get the feature. It has an A11 chip.

I updated my watch to take advantage of the reactivated blood oxygen/O2 function, but with my iPhone on public beta 3, it still shows unavailable. Will there be an update to beta three to allow this newly reactivated Apple Watch feature to function?

A UISegmentedControl as a UIBarButtonItem (customView) is ignoring selectedSegmentTintColor on iOS 26, works fine on prior versions I've submitted FB19660941 with a minimal Xcode workspace to reproduce the issue. Has anyone else seen this and identified a workaround?

Woke up to see my table gone. Whoa. What happened. FB19400940 Commenting this line in viewDidLoad or changing to softStyle brings it back. [self.tableView.topEdgeEffect setStyle:[UIScrollEdgeEffectStyle hardStyle]]; Videos in attached fb.

I have an issue where the leading UISwipeAction is offset by the size of the sidebar, but only when the sidebar is visible. Is there any known reason why this would happen?

In the latest beta of Ventura (and perhaps earlier versions) there is a section of the System Settings > General > Login Items pane called "Allow in Background". It appears that helpers (LaunchAgents/LaunchDaemons) that are installed by apps are listed here. As you can see in the screenshot below, I have 3 such items installed on my test system. The per User LaunchAgent for the Google Updater, the WireShark LaunchDaemon for the ChmodBPF script, and the LaunchDaemon for my userspace CoreAudio Driver (labelled "Metric Halo Distribution, Inc."). The WireShark and Google Updater have nice user identifiable names associated with them, whereas my Launch Daemon only has my company name associated with it. I don't see anything in the plists for Wireshark or GoogleUpdater that seem to specify this user-visible string, nor in the bundles the plists point to. How do I go about annotating my LaunchDaemon plist or the helper tool's plist so that the string in this pane helps the user properly identify what this Background item is for so that they don't accidentally turn it off and disable the driver they need to use our audio hardware? Obviously, we will document this, but just as obviously users don't always read the docs, and it would be better if the user just could make the immediate association that this Background item is needed for our CoreAudio driver.

My app does really large uploads. Like several GB. We use the AWS SDK to upload to S3. It seemed like using BGContinuedProcessingTask to complete a set of uploads for a particular item may improve UX as well as performance and reliability. When I tried to get BGContinuedProcessingTask working with the AWS SDK I found that the task would fail after maybe 30 seconds. It looked like this was because the app stopped receiving updates from the AWS upload and the task wants consistent updates. The AWS SDK always uses a background URLSession and this is not configurable. I understand the background URLSession runs in a separate process from the app and maybe that is why progress updates did not continue when the app was in the background. Is it expected that BGContinuedProcessingTask and background URLSession are not really compatible? It would not be shocking since they are 2 separate background APIs. Would the Apple recommendation be to use a normal URLSession for this, in which case AWS would need to change their SDK? Or does Apple think that BGContinuedProcessingTask should just not be used with uploads? In other words use an upload specific API. Thanks!

I know you guys probably dont care or what to help with this but I got taken down in the support communities because I simply run a beta version (didn’t even discuss it) but here we go **My MacBook Air has multiple accounts and the other users & shared category takes up 100+ gb. When I sign into one of the accounts, that 100+ gb gets moved to System Data. When I look in finder, the user only seems to take up 12 gb, though. I’ve shown hidden items and looked through the library, but it’s not showing anything that’s taking up that much space! **

This example application crashes when entering any text to the token field with FAULT: NSGenericException: The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window. The app uses controlTextDidChange to update a live preview where it accesses the objectValue of the token field. If one character is entered, it also looks like the NSTokenFieldDelegate methods tokenField(_:styleForRepresentedObject:) tokenField(_:editingStringForRepresentedObject:) tokenField(_:representedObjectForEditing:) are called more than 10000 times until the example app crashes on macOS Tahoe 26 beta 6. I've reported this issue with beta 1 as FB18088608, but haven't heard back so far. I have multiple occurrences of this issue in my app, which is working fine on previous versions of macOS. I haven't found a workaround yet, and I’m getting anxious of this issue persisting into the official release.

While testing my application on iOS beta 26, I am experiencing issues with the native UISegmentedControl component from UIKit. After implementing the control, I noticed that I am unable to switch to the second segment option—the selection remains fixed on the first segment regardless of user interaction. I have already reviewed the initial configuration of the control, the addition of the segments, and the implementation of the target-action, but the issue persists. I would like to understand what could be causing this behavior and if there are any specific adjustments or workarounds for iOS 26. I created a minimal application containing only a UISegmentedControl to clearly demonstrate the issue.
