Using the iOS 26 beta simulator, I am experiencing a crash using the QLPreviewController. This is easily reproduced using a small sample app and a sample excel file in the bundle. It does work in prior Xcode 16.4 and simulators (18.5). I didn't find any mention of this in Xcode 26 or iOS 26 release notes but I could have missed something. I don't have a spare device to update to iOS 26 and try on a real device so it may just be a simulator issue? Any feedback would be helpful. Thanks. Error: QuickLook/QLHostRemoteViewModel.swift:37: Fatal error: No extensions could be found matching '_AppExtensionQuery(extensionPointIdentifier: "com.apple.quicklook.UIExtensionPoint", predicate: nil, hostAuditToken: nil, extensionPoint: nil, allowsDuplicates: true)' Sample view controller... import UIKit import QuickLook class ViewController: UIViewController, QLPreviewControllerDataSource { var excelFileURL: URL! override func viewDidLoad() { super.viewDidLoad() // Load the Excel file (example: from bundle) if let url = Bundle.main.url(forResource: "file_example_XLSX_100", withExtension: "xlsx") { excelFileURL = url presentPreviewController() } } func presentPreviewController() { let previewController = QLPreviewController() previewController.dataSource = self present(previewController, animated: true, completion: nil) } // MARK: - QLPreviewControllerDataSource func numberOfPreviewItems(in controller: QLPreviewController) -> Int { return 1 } func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem { return excelFileURL as QLPreviewItem } }

I'm working on a catalyst video editor and I'm using my wacom graphic tablet to work. The wacom input gets translated into a pencil touch. Whenever I hold down a modifier (shift, cmd etc) the touch gets ended and also ends all gestures. The mouse (indirectPointer touch) doesn't exhibit this kind of behavior. Is this expected behavior? If so is there a way to opt out? Any way to prevent this? This basically makes the typical transform gestures impossible to do when using the graphic tablet.

Hi, I have a SwiftUI View, that is attached to a 3D object in Reality View. This is supposed to be a HUD for the user to select a few things. I wanted a sub menu for one of the top level buttons. But looks like none of the reasonable choices like Menu, Sheet or Popover work. Is there a known limitation of RealityKit Views where full SwiftUI cannot be used? Or am I doing something wrong? For example, Button { SLogger.info("Toggled") withAnimation { showHudPositionMenu.toggle() } } label: { HStack { Image(systemName: "rectangle.3.group") Text("My Button") } } .popover(isPresented: $showHudPositionMenu, attachmentAnchor: attachmentAnchor) { HudPositionMenuItems(showHudPositionMenu: $showHudPositionMenu, currentHudPosition: $currentHudPosition) } This will print "Toggled" but will not display the MenuItems Popover. If it makes any difference, this is attached to a child of a head tracked entity.

I am attempting to start my application on iOS 26 with Xcode 26. It uses an UISplitViewController that is instantiated through a Storyboard. It uses the "Unspecified" style, which is a holdover from a previous version of iOS. I'm not sure if this is a bug in iOS, or if I am supposed to change it now. The viewControllers property only has the primary view controller on iOS, although it has the primary and detail view controllers on iPadOS. When I start the application on iOS 18.5, it has both primary and detail controllers on both platforms.

I'm currently working on implementing a character limit for Korean text input using UITextField, but I've encountered two key issues. 1. How can I determine if Korean input is complete? I understand that markedTextRange represents provisional (composing) text during multistage text input systems (such as Korean, Japanese, Chinese). While testing with Korean input, I expected markedTextRange to reflect the composing state. However, it seems that markedTextRange remains nil throughout the composition process. 2. Problems limiting character count for Korean input I’ve tried two methods to enforce a character limit. Both lead to incorrect behavior due to how Korean characters are composed. Method 1 – Before replacement: func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { guard let text = textField.text else { return true } return text.count <= 5 } This checks the text length before applying the replacementString. The issue is that when the user enters a character that is meant to combine with the previous one to form a composed character, the input should result in a single, combined character. However, because the character limit check is based on the state before the replacement is applied, the second character does not get composed as expected. Method 2 – After change: textField.addTarget(self, action: #selector(editingChanged), for: .editingChanged) @objc private func editingChanged(_ sender: UITextField) { guard var text = sender.text else { return } if text.count > limitCount { text.removeLast() sender.text = text } } This removes the last character if the count exceeds the limit after the change. But when a user keeps typing past the limit, the last character is overwritten by new input. I suspect this happens because the .editingChanged event occurs before the multistage input is finalized, and the final composed character is applied after that event. My understanding of the input flow: Standard input: shouldChangeCharactersIn is called replacementString is applied .editingChanged is triggered With multistage input (Korean, etc.): shouldChangeCharactersIn is called replacementString is applied .editingChanged is triggered Final composed character is inserted (after all the above) Conclusion Because both approaches lead to incorrect character count behavior with Korean input, I believe I need a new strategy. Is there an officially recommended way to handle multistage input properly with UITextField in this context? Any advice or clarification would be greatly appreciated.

Hi, I can't get onScrollPhaseChange to fire when using a List. It works as expected when using a ScollView and LazyVStack. Interestingly, onScrollGeometryChange gets called as expected for both List and ScrollView. Has anyone successfully used onScrollPhaseChange with a List?

Prior to iOS 26, it was possible to design an inputAccessoryView(Controller) that would integrate seamlessly with the system keyboard, by which I mean appearing as a natural extension of the system keyboard. For example, using CYRKeyboardButton https://github.com/tmcintos/CYRKeyboardButton. To date, I have successfully used this to provide an enhanced numeric key row within my apps, which is a distinguishing feature of these apps. It took a lot of engineering and testing effort to perfect this design. However, with iOS 26 the design is completely broken due to the system keyboard UI change, which makes it impossible to display an inputAccessoryView seamlessly along the top of the system keyboard (see attached screenshots). In my opinion, it is just plain reckless for Apple to make these kinds of trivial UI changes, which break existing app designs without adding any significant value to the user experience. iOS ≤ 18.x: iOS 26 beta:

Hello, I have a question about FocusState, navigationLink and sheet, the code which in navigationLink closure doesn’t work, but work without navigationLink, just like the following code struct ContentView: View { var body: some View { NavigationStack { // this work interView() // this doesn't work NavigationLink { interView() } label: { Text("into interView") } } } } struct interView: View { @FocusState var focusStateA : Int? @State var show : Bool = false @State var text: String = "" var body: some View { ScrollView { VStack { coreView Button("Detail") { show.toggle() } } .sheet(isPresented: $show, content: { coreView }) } } } extension interView { var coreView : some View { VStack { VStack { putdown TextField("hi", text: $text) .focused($focusStateA , equals: 1) } } } var putdown : some View { Button(action: { if focusStateA != nil { focusStateA = nil print("OK") } else { print("It's nil") } }, label: { Text("Put down the keyboard") }) } } and there are some strange phenomena, I must put all view into a scrollview, otherwise, it even doesn’t work without navigationLink This problem has existed in IOS 18, and now in IOS26 still doesn’t be settled, is it a problem or some character?

I'm developing a CarPlay version of my app, with the CarPlay EV Charging App entitlement (com.apple.developer.carplay-charging). However, I would like to use the Search template to searching for charging stations — but it seems this template is only available for Navigation Apps(maps). In this case, what is the recommended approach? Is it possible to apply both entitlements simultaneously and use the Search template only?

Can I adjust the color properties of disclosure carets in an Outline Disclosure List view (with NavigationLinks for the list entries) in visionOS? I have color for these carets using .foregroundStyle(.accent) and it works, however, I want to change the “brightness” of those accented color carets.

I’ve noticed with the new design language, SwiftUI views appear to not use color as much. Example, color modifiers for List View items like carets. Is this intended and can developers introduce color back into SwiftUI view elements, if desired, like in iOS/iPadOS 18? Specifically, accent color not been used in List disclosure outline carets.

Prior to visionOS 2.5, .onTapGesture was called with the following structure, but in visionOS 26.0 beta, it is no longer called. Is .onTapGesture deprecated in visionOS 26.0 and above? Or is it a bug? TabView(selection: $selectedTab) { WebViewView(selectedTab: $selectedTab) .onTapGesture { viewModel.userDidInteract = true } }

Hi, I have a List and I want to limit the dynamic text size for some of the elements in the list's row item view. I created a test view below. The ".dynamicTypeSize(.large)" restriction only works if it's applied to the List view, not if it's set for the the ContentItemView in the ForEach below. Is there a reason for this? Do I need to do something else to limit a list row to a certain size? The example only has a text field, but I want to do this for a Image with some text inside it, and I wanted to restrict that text field, but it doesn't seem to work when the view is inside a List row. Please let me know if there's a workaround for it. import SwiftUI import CoreData struct ContentView: View { @FetchRequest( sortDescriptors: [NSSortDescriptor(keyPath: \Item.timestamp, ascending: true)], animation: .default) private var items: FetchedResults<Item> @State private var multiSelectedContacts = Set<Item.ID>() var body: some View { NavigationStack { List (selection: $multiSelectedContacts) { ForEach(items) { item in ContentItemView(item: item) } .dynamicTypeSize(.large) // <-- doesn't works } .dynamicTypeSize(.large) // <-- THIS WORKS } } } struct ContentItemView: View { @Environment(\.managedObjectContext) private var viewContext @ObservedObject var item: Item @State var presentConfirmation = false var body: some View { HStack { if let timestamp = item.timestamp, let itemNumber = item.itemNumber { Text("\(itemNumber) - \(timestamp, formatter: itemFormatter)") } } .popover(isPresented: $item.canShowPopover, content: { Text("Test Item Label") .frame(width: 100, height: 150) }) } } private let itemFormatter: DateFormatter = { let formatter = DateFormatter() formatter.dateStyle = .short formatter.timeStyle = .long return formatter }() #Preview { ContentView().environment(\.managedObjectContext, PersistenceController.preview.container.viewContext) }

I'd like to support different template views within a ViewThatFits for items within a list, allowing the list to optimize its layout for different devices. Within the child views is a Text view that is bound to the name of an item. I'd rather the Text view simply truncate the text as necessary although it instead is influencing which view is chosen by ViewThatFits. I'd also rather not artificially set the maxWidth of the Text view as it artificially limits the width on devices where it's not necessary (e.g. iPad Pro vs. iPad mini or iPhone). Any guidance or suggestions on how this can be accomplished as it looks very odd for the layout of one row in the list to be quite different than the rest of the rows.

With the advent of APNs pushs to Widgets, I would like to confirm some things. I understand that we have a budget of updates for it, however is the budget for APNs part of the budget for background updates? In other words, 1 budget for both or 2 separate budgets? Also, can we make a push to an individual widget, or are we essentially calling .reloadAllTimelines()?

With the latest iPadOS 26 changes, the traditional multitasking experience using Slide Over and Split View has been removed in favor of Stage Manager. While Stage Manager is a great option for some, the old multitasking UI was more intuitive, stable, and ideal for quick productivity. Please consider restoring the classic multitasking gestures as an optional feature or toggle alongside Stage Manager. Many users like myself rely on the traditional layout for studying, work, and multitasking efficiency.

I have a floating action button in my app above a toolbar. The action button adds items to my app, so is pretty important and should be easy to reach. Now with the new liquid glass design, I wonder what the best way is to combine those two. Should I use .tabViewBottomAccessory() for that? Though, that will merge down on scroll. 🤔 Or can I replace the search button in the bottom right with my own custom button action?

When exporting an icon using Icon Composer Beta for macOS 26, a light, dark and tinted versions for macOS are created, but I was not able to find how to use them on the Xcode Project. I also tried finding something pointing to that on documentation, but I was not able to find anything. I see that system apps have light, dark and tinted versions on the first beta of macOS 26, which leads me to believe it would be possible for third-party apps to do that same.

I have noticed that in iOS 14 the UIPickerView has by default a light grey background on the selected Row like shown here. https://developer.apple.com/design/human-interface-guidelines/ios/controls/pickers/ I noticed also that pickerView.showsSelectionIndicator is deprecated on iOS 14. Is there a way to change the background color to white and add separators to achieve a pre iOS 14 UIPickerView style? Thank you
