Avoid trackpad gesture conflict between dragging and accessibility zooming when using three fingers
Double-tap three fingers and drag to change zoom” should suppress “Three Finger to Drag”. Currently these gestures are triggered simultaneously, for no real reasons. I saw different behaviors for different environments, but none is desired. Current and desired behavior: This seems an issue so I filed a feedback.

Compositional Layout's broken `visibleItemsInvalidationHandler`
Hello everybody! TLDR: Issues with visibleItemsInvalidationHandler. Minimal code to reproduce available. I've been working with Compositional Layout for a while now and recently I've found myself needing to implement custom animation based on scroll position of UI elements. Once I found visibleItemsInvalidationHandler it felt like the exact solution that I needed. Once I implement I've found out it doesn't quite behave as you'd expect. To put it simply, it seems like the animations only work if your whole layout does not use .estimated nor .uniformAcrossSiblings. As soon as you use them then the animations will stop working, I've debugged it deeper and it seems like the invalidation context generated by it does not include the indexPath of the cells, which is always included in the version in which it works. Feel free to swap the line 51 with its comment to flip between the working and failing version of it. Playground Example My final question therefore is... Is this the expected behavior? The documentation doesn't give any clues about such behavior and although I've tried relentlessly to find a workaround for this specific hiccup I was not successful with it.

Automatic menu translation ok with El Capitan, notok with Mojave
Hi everybody, I use a very old photo software called Snapseed v 1.2.1 on 2 MacBook, one runs with El Capitan and the second runs with Mojave. These app has no language selection during install, and no preferences language choice in menu when running. When I execute app on El Capitan, all menus and topics are translate in French, but on Mojave no translation is done. I looked Contents of app and found differents languages files (structured as xx.po where xx=country) located in Resources folder. I deduced translation was executed after getting language param. I checked values on both systems and there are same (LANG=fr_FR.UTF-8). So I tried to change Info.plist file to force code langage to 'fr' in CFBundleLocalizations key. Result is same. Does somebody has a idea of reason of issue and how to solve it ? Snapseed release was 2012, El Capitan 2015 and Mojave 2018, it seems framework used to code app runs differently and can't get language value.

Webview In-App Browser Microsoft Login Redirection Not Working
Hello, We received a rejection on one of our IOS applications because we were doing Microsoft MSAL login through the user's browser. The representative recommended that we use Webview to do in-app logins. However when we tried to handle the custom app uri redirection (looking like myapp://auth/), Webview does not seem to send the user back to the application. Does anyone have a fix for this? Thanks!

Weird transparency in sidebar in iPad app
I have an iPad app with a classic sidebar. It's been working fine for years. Now with iPadOS 26 the sidebar sometime gets this fake transparency that makes it really hard to quickly grok. A part of Liquid Glass seems to be to sometimes (but not always) take whatever is in the secondary area (the main big content), blur it, mirror it and then use as the background for the sidebar. This is silly and does not work at all for an app like mine. It maybe looks decent if your background is a photo or similar, but not for an app that manages data. Not all views cause the sidebar to get this ugly unreadable background. In most of the cases the sidebar keeps its normal opaque background that it has always had. See this example for how it looks when it's really bad: This is how it should look. Notice that the content of the "main view" is pretty similar to the case where it gets the ugly background. The difference is the segmented thing at the top, ie. a different "root view". Is there some good way for me to force the sidebar to always have an opaque background? I guess I could make a ZStack and put a solid color as the background behind the sidebar, but those kinds of hacks are better to avoid. This can not be how some UI designer envisioned that apps should look? Maybe I'm missing some new modifier or setting somewhere that would led me opt out from this aspect of Liquid Glass? Apart from this it looks pretty nice. There are some bugs where the contents of the main area gets clipped when the sidebar is shown, hidden and then shown again, but that's for another time (and it's surely known already (if the bug tracking system allowed me to search I could verify)). So, any way to make my app look nice again?

Incorrect system color on popover view, and does not update while switching dark mode on iOS 26 beta 3
All system colors are displayed incorrectly on the popover view. Those are the same views present as a popover in light and dark mode. And those are the same views present as modal. And there is also a problem that when the popover is presented, switching to dark/light mode will not change the appearance. That affected all system apps. The following screenshot is already in dark mode. All those problem are occured on iOS 26 beta 3.

Expandable cell in List View shows slowly after swiping to delete it
If the cell is expandable in List View, it will show slowly after deletion swipe. the image shows how it looks like when this issue happens and it should be easy to reproduce with this sample codes // Model for list items struct ListItem: Identifiable { let id = UUID() let title: String let createdDate: Date let description: String } struct ExpandableListView: View { // Sample constant data private let items: [ListItem] = [ ListItem( title: "First Item", createdDate: Date().addingTimeInterval(-86400 * 5), description: "This is a detailed description for the first item. It contains two lines of text to show when expanded." ), ListItem( title: "Second Item", createdDate: Date().addingTimeInterval(-86400 * 3), description: "This is a detailed description for the second item. It provides additional information about this entry." ), ListItem( title: "Third Item", createdDate: Date().addingTimeInterval(-86400 * 1), description: "This is a detailed description for the third item. Tap to expand and see more details here." ), ListItem( title: "Fourth Item", createdDate: Date(), description: "This is a detailed description for the fourth item. It shows comprehensive information when tapped." ) ] // Track which item is currently selected/expanded @State private var selectedItemId: UUID? = nil var body: some View { NavigationView { List { ForEach(items) { item in ExpandableCell( item: item, isExpanded: selectedItemId == item.id ) { // Handle tap - toggle selection withAnimation(.easeInOut(duration: 0.3)) { if selectedItemId == item.id { selectedItemId = nil } else { selectedItemId = item.id } } } } .onDelete { indexSet in for index in indexSet { print("delete \(items[index].title)") } } } .navigationTitle("Items") } } } struct ExpandableCell: View { let item: ListItem let isExpanded: Bool let onTap: () -> Void private var dateFormatter: DateFormatter { let formatter = DateFormatter() formatter.dateStyle = .medium formatter.timeStyle = .short return formatter } var body: some View { VStack(alignment: .leading, spacing: 8) { // Always visible: Title and Date HStack { VStack(alignment: .leading, spacing: 4) { Text(item.title) .font(.headline) .foregroundColor(.primary) Text(dateFormatter.string(from: item.createdDate)) .font(.caption) .foregroundColor(.secondary) } Spacer() // Chevron indicator Image(systemName: isExpanded ? "chevron.up" : "chevron.down") .foregroundColor(.secondary) .font(.caption) } // Expandable: Description (2 lines) if isExpanded { Text(item.description) .font(.body) .foregroundColor(.secondary) .lineLimit(2) .fixedSize(horizontal: false, vertical: true) .transition(.opacity.combined(with: .move(edge: .top))) .padding(.top, 4) } } .padding(.vertical, 8) .contentShape(Rectangle()) .onTapGesture { onTap() } } } #Preview { ExpandableListView() }

UIViewController memory leak with modal presentedViewController
Hi everyone, I'm encountering an unexpected behavior with modal presentations in UIKit. Here’s what happens: I have UIViewControllerA (let’s call it the "orange" VC) pushed onto a UINavigationController stack. I present UIViewControllerB (the "red" VC, inside its own UINavigationController as a .formSheet) modally over UIViewControllerA. After a short delay, I pop UIViewControllerA from the navigation stack. Issue: After popping UIViewControllerA, the modal UIViewControllerB remains visible on the screen and in memory. I expected that dismissing (popping) the presenting view controller would also dismiss the modal, but it stays. Expected Behavior: When UIViewControllerA (orange) is popped, I expect the modal UIViewControllerB (red) to be dismissed as well. Actual Behavior: The modal UIViewControllerB remains on screen and is not dismissed, even though its presenting view controller has been removed from the navigation stack. Video example: https://youtube.com/shorts/sttbd6p_r_c Question: Is this the expected behavior? If so, what is the recommended way to ensure that the modal is dismissed when its presenting view controller is removed from the navigation stack? Code snippet: class MainVC: UIViewController { private weak var orangeVC: UIViewController? override func viewDidLoad() { super.viewDidLoad() self.view.backgroundColor = .blue let dq = DispatchQueue.main dq.asyncAfter(deadline: .now() + 1) { [weak self] in let vc1 = UIViewController() vc1.view.backgroundColor = .orange vc1.modalPresentationStyle = .overCurrentContext self?.navigationController?.pushViewController(vc1, animated: true) self?.orangeVC = vc1 dq.asyncAfter(deadline: .now() + 1) { [weak self] in let vc2 = UIViewController() vc2.view.backgroundColor = .red vc2.modalPresentationStyle = .formSheet vc2.isModalInPresentation = true let nav = UINavigationController(rootViewController: vc2) if let sheet = nav.sheetPresentationController { sheet.detents = [.medium()] } self?.orangeVC?.present(nav, animated: true) dq.asyncAfter(deadline: .now() + 1) { [weak self] in self?.navigationController?.popViewController(animated: true) } } } } } Thank you for your help!
