I have an iOS App which looks great on iPhone, portrait only, which makes a lot of use of UITableViews. On iPad those tables look stretched out in Landscape. On MacOS with Apple Silicon the app can be resized to any size and the table views look very stretched. There are views in the App which users want to resize so limiting app size not an option. I've been modifying the app's table views to limit their width and centre them using constraints. This isn't easy, it's a lot of work as UITableViewController doesn't allow for constraining the table width. Or does it? So I've changed them to UIViewControllers with UITableView imbedded in the root UIView with constraints. Looks really nice. Now I've just run into the limitation that static tables, which I have a number of, aren't allowed to be embedded. So how can I limit the width of them? I really don't want to add a lot of dynamic code. Please tell me there's an simpler, more elegant method to what really makes a much more aesthetically pleasing UI on iOS App running on iPad and MacOS? TIA!

Does anyone else have a problem that with iPad OS18.2 beta, its not possible to set or change the wallpaper either from the lock screen or from settings. Alost means that you can’t add Widgets to the lock screen. Is this a bad update on my iPad or is this a bug?

Hi, I'm trying to create a UICollectionView where the cell high is automatic. Cells contains a UILabel with all anchors to the contentView of the cell. It seems to work but I have a strange behavior with longer text, on reload data and on device rotation: Cells do not display the whole text or they change row, both randomly. To create my collection view I first create the collection view with a custom flow layout setting the automatic size on viewWillAppear: let collectionViewFlowLayout = CustomFlowLayout() collectionViewFlowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize collectionView = UICollectionView(frame: .zero, collectionViewLayout: collectionViewFlowLayout) and I have also overridden: override func willAnimateRotation(to toInterfaceOrientation: UIInterfaceOrientation, duration: TimeInterval) { collectionView.setNeedsLayout() self.collectionView.layoutIfNeeded() self.collectionView.collectionViewLayout.invalidateLayout() //self.collectionView.reloadData() } Then, I created the custom layout as follow: import UIKit final class CustomFlowLayout: UICollectionViewFlowLayout { override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? { let layoutAttributesObjects = super.layoutAttributesForElements(in: rect)?.map{ $0.copy() } as? [UICollectionViewLayoutAttributes] layoutAttributesObjects?.forEach({ layoutAttributes in if layoutAttributes.representedElementCategory == .cell { if let newFrame = layoutAttributesForItem(at: layoutAttributes.indexPath)?.frame { layoutAttributes.frame = newFrame } } }) return layoutAttributesObjects } override func layoutAttributesForItem(at indexPath: IndexPath) -> UICollectionViewLayoutAttributes? { guard let collectionView = collectionView else { fatalError() } guard let layoutAttributes = super.layoutAttributesForItem(at: indexPath)?.copy() as? UICollectionViewLayoutAttributes else { return nil } layoutAttributes.frame.origin.x = sectionInset.left if(indexPath.section == 0){ layoutAttributes.frame.size.width = collectionView.safeAreaLayoutGuide.layoutFrame.width - sectionInset.left - sectionInset.right } else if (indexPath.section == collectionView.numberOfSections - 1){ let width = ScreenUtility.getCollectionCellWidthForElement(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing, multiplier: 3) layoutAttributes.frame.origin.x = ScreenUtility.getCollectionCellOriginForElement(in: collectionView, at: indexPath, forElementHavingWidth: width, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing, multiplier: 3) layoutAttributes.frame.size.width = width } else if (indexPath.section == collectionView.numberOfSections - 3) || (indexPath.section == collectionView.numberOfSections - 4){ let width = ScreenUtility.getCollectionCellWidthForElement(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing) layoutAttributes.frame.origin.x = ScreenUtility.getCollectionCellOriginForElement(in: collectionView, at: indexPath, forElementHavingWidth: width, sectionLeft: sectionInset.left, sectionRight: sectionInset.right, minimumInteritemSpacing: minimumInteritemSpacing) layoutAttributes.frame.size.width = width } else { let width = ScreenUtility.getCollectionCellSizeForElementFullRow(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right) layoutAttributes.frame.origin.x = ScreenUtility.getCollectionCellOriginForElementFullRow(in: collectionView, sectionLeft: sectionInset.left, sectionRight: sectionInset.right) layoutAttributes.frame.size.width = width } return layoutAttributes } } And finally on collection view cells: override func preferredLayoutAttributesFitting(_ layoutAttributes: UICollectionViewLayoutAttributes) -> UICollectionViewLayoutAttributes { setNeedsLayout() layoutIfNeeded() let targetSize = CGSize(width: layoutAttributes.frame.width, height: 0) layoutAttributes.frame.size = contentView.systemLayoutSizeFitting(targetSize, withHorizontalFittingPriority: .required, verticalFittingPriority: .fittingSizeLevel) return layoutAttributes } override func prepareForReuse() { self.nameLabel.text = "" self.idLabel.text = "" self.contentView.setNeedsLayout() self.contentView.layoutIfNeeded() } Let me show you an example on the iPad that is the worst. First Time I open the collection view I have cells on wrong rows and not sized properly Then I rotate the device portrait and the cells are fine On landscape again it changes behavior: This is just an example, things happens apparently randomly, and also sometimes cells disappear (I think the height is set to 0). I really do not understand why, cells width seems to be computed correctly, and cell label is set via setter: open var step: String = "" { didSet { nameLabel.text = step nameLabel.sizeToFit() self.contentView.setNeedsLayout() self.contentView.layoutIfNeeded() } }

I have been attempting to achieve the early access image creation (iPad iOS 18.2) and it has taken days, I still don’t have it and feel I never will. Someone heeelelllppppp!

Hi, my name is Yuki. I'm developing an application with generative AI for junior and high school students based on the Nocode tool "bubble" (BDK Native). I want to upload this app to the App Store, however, a notch-like interface element is appearing only in the iPad environment, which is causing my app to fail App Store review. I've reached out to the BDK Native support team about this issue, but they were unable to identify the cause and only offered a refund as a solution. This is particularly frustrating as I'm unable to proceed with the App Store publication, and time is passing without a resolution. Technical details: The notch appears only on iPad devices The issue is not present on iPhone versions The app was built using bubble/BDK Native Multiple App Store submissions have been rejected due to this UI issue Has anyone encountered a similar issue or knows how to resolve this iPad-specific interface problem? Any guidance or suggestions would be greatly appreciated, as this is blocking our app's release. Thank you in advance for your help!

Simulators sometimes draw the screen with the wrong aspect ratio and appear distorted. I'm on macOS 14.7 and using Xcode 16.1, but Xcode 16 was also sometimes doing this. This is happening in both iPhone simulator and iPad simulators. Is anyone else seeing this? It's not just the Home Screen, it happens in apps too. I have a weird bug when testing on the iPad simulators and I can't tell if it is a bug in the simulator or in my app. All my iPads are broken, so I can't actually test on device right now.

Hello, Apple developers. I have joined the MFi certification program. My Accessory to use USB HID IAP2 communication protocol and IOS devices connected, but in the first step, the Accessory to send the following data (0 XFF, 0 x55, 0 x02, 0 x00 to 0 xee, 0 x10) for IOS devices, but the IOS devices have no response, this is probably the reason why?

I work as the end user compute engineer at my employer. My test managed shared iPad Pro was on iOS 18.0.1 and from the sign in screen I was able to double click the lock/wake button twice to open the Wi-Fi picker. I upgraded it to the latest iOS 18.1 update and the Wi-Fi picker screen no longer comes up when double clicking the lock/wake button. Has this feature been removed? If so, this will pose a huge issue when it comes to new users signing in when not on a known Wi-Fi network.

iPadOS behavior with secondary displays is inconsistent. Firstly, Apple has not published what is the lower limit for supporting the extended display in non-mirrored mode. In iPadOS 16.1 beta even lower resolutions were supported, but it looks like the monitor must now support at least Full HD (1920x1080). Otherwise there will only be the possibility for mirroring the iPad screen and the Arrangement menu will not be visible in iPadOS Settings. This is the case with all iPadOS versions from 16.1 to 18.2 (beta). Secondly, even on monitors that do support Full HD or better resolution, iPadOS may still choose to only support mirroring with a strange resolution such as 1280x1024 even though 1920x1080 would be available. I have tested with various iPad Pro 11" models from gen 1 to gen 4, various USB-C adapters, and cables. Extended display does work properly with certain monitors, but the above issues still exist on others. I have filed feedbacks FB13576000 (Feb '24) and FB11467189 (Sep '22) on this bug. On the Support Community Forums there are a lot of users mentioning the same issues.

There are significant crash reports coming from iOS 18 users regarding AVKit framework that starts from this line [AVPlayerController _observeValueForKeyPath:oldValue:newValue:] which seems to be coming from iOS internal SDK. There are 2 kinds of crash we found: UI modification on background thread From the stack trace it seems like when AVPictureInPictureController is being deallocated and its view is being removed from superview somehow the code is being executed in background thread because there is this line there _AssertAutoLayoutOnAllowedThreadsOnly highlighted before the crash. But I’ve checked our code that plays around AVPictureInPictureController, in the locations where we would deallocate the object it will always be called on main thread which are insideviewDidLoad and deinit inside UIViewController class. From the log, it seems like the crash happened when user try to open another content when PIP player is active resulting in the current PIP instance will be replaced with a new one. My suspect is the observation logic inside AVPlayerController could be the hint to this issue, probably something broken over there since this issue happened across our app versions on iOS 18 users only. Unfortunately, I was unable to reproduce this issue yet but one of my colleagues reproduced it once but haven’t been able to do it again since. The reports keep raising each day up to 1.3k events in the last 30 days now. Over release object This one has lower reports than the first one but I decided to include it since it might have relevant information regarding the first crash since the starting stack trace is similar. The crash timing seems to be similar to the first one, where we deallocate existing AVPictureInPictureController and later replace it with a new one and also found only in iOS 18 users which also refers to [AVPlayerController _observeValueForKeyPath:oldValue:newValue:]. I also was unable to reproduce this issue so far. Oh, and both of the issues happened on both iPhone and iPad. We’d appreciate any advice on what we can do to avoid this in the future and probably any hint on why it could happened. I have reported this issue with bug number: FB15620734 I also attached one sample crash report for each of the crashes here. non ui thread access.crash over release.crash

I am creating an application using PKCanvasview. One function of that app is the ability to trace and retrieve a UITextView that has been addSubviewed to a PKCanvasView. We have confirmed that this functionality works correctly in the simulator and on the actual device on IOS 17.4. This feature did not work correctly on the IOS18 simulator and the actual device. Is this a bug? And if it is normal behavior, is there an alternative?

Hi, is there any way to interact with the eye tracking accessibility feature in iOS and iPadOS? I want to be able to trigger an eye tracker recalibration programmatically. Also if possible, I would like to be able to retrieve gaze location data. These are not intended to be features on an app being published to the app store but rather a custom made accessibility app.

https://support.apple.com/en-gb/guide/deployment/dep6fa9dd532/web dangles a carrot about being able to facilitate "A list of domains that the Shared iPad sign-in screen displays. The user can pick a domain from the list to complete their Managed Apple ID." - this sounds ideal! In the absence of this seemingly being supported by Apple Configurator or iMazing Profile Editor at the time of writing, I have tried to create my own but I fall foul of knowing what PayloadIdentifier or PayloadType to use? This is the draft/work in progress/doomed to failure config so far (which doesn't - as expected - work): <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>HasRemovalPasscode</key> <false/> <key>PayloadContent</key> <array> <dict> <key>PayloadDescription</key> <string>Configures Managed Domains</string> <key>PayloadDisplayName</key> <string>Domains</string> <key>PayloadIdentifier</key> <string>com.apple.domains.DE12211A-CFDD-4F8C-8D7B-72E569CE3B6C</string> <key>PayloadType</key> <string>com.apple.domains</string> <key>PayloadUUID</key> <string>DE12211A-CFDD-4F8C-8D7B-72E569CE3B6C</string> <key>PayloadVersion</key> <integer>1</integer> <key>WebDomains</key> <array> <string>domain.com</string> </array> </dict> </array> <key>PayloadDescription</key> <string>For Shared iPad login convenience</string> <key>PayloadDisplayName</key> <string>DefaultDomain</string> <key>PayloadIdentifier</key> <string>Tom.77CF3CA5-4A48-41DD-9179-EF6F4C5E786E</string> <key>PayloadRemovalDisallowed</key> <true/> <key>PayloadType</key> <string>Configuration</string> <key>PayloadUUID</key> <string>A5594F17-155B-4A1C-8696-3F502D118C37</string> <key>PayloadVersion</key> <integer>1</integer> </dict> </plist> The support article is probably ~2-year old information so I'd have thought that by now that this would be documented somewhere - am I just not looking hard enough?

Hi! I'm developing a custom keyboard and my user reported that they can't switch to my keyboard while using external original iPad keyboard. Unfortunately, I can't test it on a real device and I can't find a way to test it using a simulator. My questions: Is it possible to simulate this case on a simulator? Is it possible to temporarily show a custom keyboard while using an external keyboard on iPad? I saw in the photos that this keyboard has a globe button, but my user told me that nothing happens when they hold or press hit.

Hello, I am currently implementing the new iPadOS 18 TabBar with the new Tab API, but there are several things that don't look very good or aren't operating quite the way I'd hope and would like to know if there is a way around them or to change them. Here is what my sidebar for the TabBar looks like: My questions: The tabViewSidebarBottomBar isn't actually at the "bottom". Instead there is a gap below which you can see the sidebar scrolling. Is there a way to get the tabViewSidebarBottomBar actually at the bottom? Is there a way to make it so that the sections themselves are also reorderable? Can we turn scrollIndicators to .never or are we stuck with them being on? Is there any way at all to make the SF Symbols in the sidebar render in another color mode, particularly .palette? Is it possible to allow sections in between plain tabs? Like I want Dashboard, then the whole Events section, then the rest can continue. On iPhone why are sections not honored at all, in any way? Like even if they weren't going to be expandable menus, at least treating it like a list section would allow some visual hierarchy?! Bonus Question: Any way to make the tabViewSidebarHeader sticky so it's always at the top? Thank you in advance!

I have apple intelligence working fine with all the features on my iPhone 16 pro max. except for the summary feature and email summarizing, they don't work unless I turn on VPN on. why is that ? I am not living in the EU. and all the features of AI are working except for this one it won't work unless I have my vpn on. can anyone help me with this.

Running an existing Xcode project in an iPad OS 18 simulator is automatically using the newly introduced tab bar view, moved from the bottom to the top. Unfortunately, the isEnabled property on a tar bar item is no longer honored. In Xcode's Storyboard builder, some tab bar items are initially disabled. (can't add a screenshot here, I will try to do that after posting) The iPad OS 17 simulator shows them correctly as disabled and any user interaction is suppressed as expected. The iPad OS 18 simulator shows them as active and they can be selected. Also setting them to disabled inside of the UITabBarViewController doesn't work: for item in self.tabBar.items! { if item.tag != 99 { item.isEnabled = false } } They stay enabled and selectable. As a workaround, I implemented the UITabBarViewControllerDelegate and overrode this method: func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool { if Global.shared.accessToken == nil { if viewController is LoginViewController || viewController is SettingsViewController { return true } else { return false } } return true } The user can no longer select the tabs, however, there is no visual indicator that they are not selectable. I cannot find any indication in the release notes or documentation, that this behavior is intentional. So I assume this is a bug.

I found iPadOS18 displayed navigation bar incorrectly when transition from screen with hidden navigation bar to screen that show navigation bar. I have 2 ViewController: FirstViewController and SecondViewController. FirstViewController navigationBar set isHidden to be true (hidden) and SecondViewController navigationBar set isHidden to be false (showing). When transition from FirstViewController to SecondViewController, the navigation bar is displayed incorrectly as shown in picture below: Actual Expected Note I set hide navigation bar in viewWillAppear() in both ViewController override func viewWillAppear(_ animated: Bool) { navigationController?.setNavigationBarHidden(..., animated: true) } source code: https://github.com/ornthita/TestTabbar

Hi, The company produces MFI-certified devices. A lot of users are affected. it happens when users are in the background. The crash happens in NSArray; it looks like the array is out of bounds to which EAAccessoryManager tries to access. The only assumption I have is that something is wrong with Threads. Maybe we are blocking a Thread somewhere, or EAAccessory should always work on the Main Thread but we switch streams to another thread. It is hard to believe that Apple could have such a simple bug. If it were Apple's bug, other companies who produce MFI devices could also experience the identical bug, but I don't see anyone raising the identical issue. The issues don't have a relation to iOS versions; it happens for us from iOS 13 till iOS 18. Thanks in advance, Eugene.

I have been playing around with the page layout on my IPad Pro and discovered that is is impossible to group apps if you leave an empty space in the page. I found the option fun to finally place my apps where i want and not just lined up from top to bottom. I discovered if you leave gaps in the page layout it is impossible to groupe apps. The moment you hover the app over the groupe, the groupe shifts back to fill the empty space. Once I filled up all the empty space then the groupe stops moving. It is pretty annoying. The was excited to see the new feature to finally hate it completely. I do hope someone will fix this problem.
