iPadOS 17.7.7

The iPadOS display Reference Mode is a large part of what I need for a colour measurement app I have written. I want to disable the Auto Brightness, True Tone, and other tools that vary the display brightness, and produce a given, known brightness. I can ask the user to disable all these, but I cannot test whether they are disabled within the app. I have found that my iPhone display is close enough to sRGB that the differences when matching to my macBook are probably due to the difference in spectrum between OLED and LCD other than any errors in calibration. It does not matter to me if we cannot set my iPhone display values to the precision or the brightness range of the iPad Pro. We expect differences from metamerism when matching different spectra. The important thing for me is to get the display to the same brightness and white in some repeatable way.

After upgrading my iPad to iPadOS 26.0, I noticed that when using UIPopoverPresentationController, the popover no longer appears at the expected position. According to the debug logs, the position of the arrow indicator is printed correctly. Interestingly, the issue can be fixed temporarily by switching between portrait and landscape orientations. Could you please help me resolve this issue?

I have an app written that has been working for over 3 years. The app is installed via OTA. Was contacted by user yesterday with an iPad Air 3rd generation with ipados 13.3 and the app will not install on his device. It says the certificate is not valid. This is the first time in over 3 years we have had an issue where the app will not install on a device. It appears to correctly install on any other ipad (have not had any calls) but outside the ipad air 3 there, all the other ipads were released in 2018. Did apple change something with the new ipads that come out in 2019 to use a different certificate type causing the install to fail?

We are observing that for devices with iPadOS 26, table views within apps are unexpectedly auto scrolling. The issue can be reproduced as follows: The table view has enough cells to the point where not all cells can fit on the screen and the table view is scrollable User has scrolled to the bottom of the tableView and tableView.reloadData() is called. One of the following applies: The ViewController containing the tableView is embedded in a UINavigationController, and ViewController sets self.edgesForExtendedLayout = .bottom The ViewController containing the tableView is embedded in a UINavigationController, and UINavigationController sets navigationBar.isTranslucent = false The following constraints are applied to the tableView: tableView.topAnchor.constraint(equalTo: view.layoutMarginsGuide.topAnchor).isActive = true tableView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true tableView.rightAnchor.constraint

Hello, Right when iPadOS 15 is released in the Fall, I'll want to support the new large widget and a few of the other iPadOS 15 specific features. I'm working on them now in the Xcode 13 Beta, but to give these features out to users on launch day, can I update my app now with these features from the Xcode 13 Beta? Or would I need to wait until Xcode 13 is public? Sorry if this question seems simple. This is my first time launching on the new update's release day, so I am unsure if I can submit those new features now or wait until launch day. Please let me know! P.S. My app is multi-platform (iOS, iPadOS, and macOS). Would submitting early from an Xcode beta potentially mess up the other platforms?

Why is Feedback Assistant app missing in iPadOS 14.2? Seems to be missing on iOS 14.1 too. I need to report a serious bug on the iPad - audio from a video plays even AFTER an app is quit in some unexplained cases. You have to start another audio source and then stop that one to regain control of your iPad.

Hi everyone, I'm working with a third party to integrate their USB driver into our app and I'm wondering if iPadOS supports bundling a prebuilt .systemextension file with the entitlement com.apple.developer.system-extension.redistributable into our app that has the com.apple.developer.driverkit.communicates-with-drivers entitlement? If not, is there a way to bundle a third party USB driver into our iPad app?

I want the sidebar to show if a user launches my app in portrait mode on iPadOS. I using SwiftUI so I'm hoping there is an easy way to do that.

I've encountered an issue when using TabView inside a Popover on iPadOS, and I wanted to see if anyone else has run into this or if there's a known workaround before I file a bug report. Issue: When placing a TabView inside a Popover on iPadOS, the tab bar is not center-aligned correctly if the popover’s arrow appears on either the leading or trailing edge. It seems that the centering calculation for the TabView includes the width of the arrow itself. If the popover arrow is on the left, the tabs inside the TabView are pushed to the left. If the popover arrow is on the right, the tabs shift toward the right. This suggests that SwiftUI is incorporating the popover arrow’s width into the alignment calculation, which results in the misalignment. Questions: Has anyone else encountered this behavior? Is there a known workaround to ensure proper centering? If this is indeed a bug, should I file a report through Feedback Assistant? Any insights would be greatly appreciated!

I have an app that runs eitheir as MacOS or iPadOS. After a few changes to adapt to API differences (PasteBoard notably), app runs OK on both. But the layout of views is messy when running on iPad. Reason seems to be that Text are not using the same default font size, or that the same system font size does not use the same space. Same issue when using segmented picker for instance. Configuration: Xcode 14.2 MacOS 12.6.6 Simulator: iPad Pro (12.9) - iOS 16.2 Is it a correct analysis ? Is there a simple workaround, to avoid the need to redesign all views for iPadOS ?

I have found a bug in iPadOS 15 in a UIKit app that is a legacy Objective-C app. This app has full screen presentation and uses UINavigationView at the top level, from the UIApplicationDelegate. In the UIApplicationDelegate the UINavigationBar is hidden, and does not become visible again in the app. This app has functioned correctly for years, but recently I decided to try adding a hosted SwiftUI view as a view controller component. The way this works is that I create a Container view controller that hosts the SwiftUI UINavigationController - ParentUIViewController - ContainerUIViewController - HostingViewController - SwiftUI View. The ContainerUIViewController contains logic for instantiating the hosted SwiftUI view and performing correct child view controller insertion and removal from the container. This worked on iPadOS 14, but on iPadOs 15 the presentation of the hosted SwiftUI view causes the NavigationBar to appear. Once presented it cannot be hidden by commands to hide the b

Hi, is VP9 support available to MacOS alone? On iOS 14 youtube is playing 4K Videos(supported 4K only in webm(vpx)), but when i try to create VP9 codec with videoToolBox, always it is failing. status = VTCopyVideoEncoderList(nil,&array); No Vp9 encoder available. let isHWSupported = VTIsHardwareDecodeSupported(kCMVideoCodecType_VP9); VP9 hardwareDecoder not supported. And when tryed to create VP9 decoder even when hardware acceleration not supported, it is failing(expected as VT supports hardware only video codecs). we can't even register supplementary decoders in iOS. is VP9 really supported on iOS, how youtube playing VP9 on iOS and iPadOS? Checked on latest iOS 14.0.1, iPhone11 pro.
