Issue Summary: iOS 26 UI components are not visible in the Expo app when installed via TestFlight. All components render correctly in local builds or when running with expo run:ios. Details: The app is built using Expo managed workflow. iOS 26-specific UI components do not appear in TestFlight builds. The same components display correctly in local builds and simulators. Test device: iPhone running iOS 26.1. There are no crashes or runtime errors; only the components are missing. This issue occurs only in TestFlight/release builds. Expected Behavior: All iOS 26 UI components should render in TestFlight builds the same way they do in local builds. Actual Behavior: Components fail to render or are completely missing. Device Information: Device: iPhone iOS Version: 26.1 Distribution: TestFlight Local Build: Working correctly Additional Notes: This may be related to Expo release build optimization or iOS 26 SDK compatibility.

Dear random Apple UIKit engineer. This is a question for you. Today let's speak about keyboard notifications. In particular, UIResponder.keyboardWillShowNotification and UIResponder.keyboardWillHideNotification. While working with those, I noticed some undocumented behaviour. First, let me give you some context: extension UIViewController { func registerForKeyboardNotifications() { NotificationCenter.default.addObserver(self, selector: #selector(keyboardNotification), name: UIResponder.keyboardWillShowNotification, object: nil) NotificationCenter.default.addObserver(self, selector: #selector(keyboardNotification), name: UIResponder.keyboardWillHideNotification, object: nil) } /// Override this method to handle keyboard notifications. @objc func keyboardNotification(_ notification: Notification) { ... } } Eventually, I found that latter method with 3 dots has an implicit animation inside it's scope. Here is the [proof.](https://medium.com /uptech-team/why-does-uiresponder-keyboard-notification-handler-animate-10cc96bce372) Another thing I noticed, is that this property definition is perfectly valid let curve = UIView.AnimationCurve(rawValue: 7)!. The 7 btw comes from UIResponder.keyboardAnimationCurveUserInfoKey as a default value during my tests. So, the enum with 4 possible values (0...3) can be initialized with a value out of enum's cases range. Also, how can I initialize UIView.AnimationOption from 7? I will pollute my OptionSet which I feed to options parameter on UIView.animate(...) My questions: Why implicit animation is not documented and can I trust it or it's a subject to change. Why UIView.AnimationCurve(rawValue: 7)! does not crash. How can I convert UIResponder.keyboardAnimationCurveUserInfoKey's value into UIView.AnimationOption properly if I don't want to use implicit value. I don't encroach on UIKit secrets. I just need to know how to work with the API. Thank you!

I want to support Genmoji input in my SwiftUI TextField or TextEditor, but looking around, it seems there's no SwiftUI only way to do it? If none, it's kind of disappointing that they're saying SwiftUI is the path forward, but not updating it with support for new technologies. Going back, does this mean we can only support Genmoji through UITextField and UIViewRepresentable? or there more direct options? Btw, I'm also using SwiftData for storage.

I am trying to use Zone Sharing in my SwiftUI app. I have been attempting to get the UICloudSharingController to show an initial share screen to pick users and the mechanism to send the invitation. From the documentation, it appears that the UICloudSharingController .init(preparationHandler:) API is deprecated so I am not using that approach. Following the Apple documentation, I am creating a Zone Share and NOT saving it and presenting using the UICloudSharingController(share:container:) API. However, this presents a UI that is the 'mgmt' API for a Share. I can get to the UI I was expecting by tapping on the 'Share with More People' option, but I want to start on that screen for the user when they have not shared this before. So, I found an example app from Apple at: https://github.com/apple/sample-cloudkit-zonesharing. It has the same behavior. So we can simply discuss this problem based on that example code. How do I get the next View presented when tapping 'Share Group' to be the invitation for new users screen? Here is the UI it presents initially: And here is the UI (on the bottom half of the screen) I am trying to start the share process with: Thanks, Charlie

I've been struggling with this issue since the release of macOS 15 Sequoia. I'm wondering if anyone else has encountered it or if anyone has a workaround to fix it. Inserting a new element into the array that acts as data source for a SwiftUI List with a ForEach is never animated even if the insertion is wrapped in a withAnimation() call. It seems that some other changes can be automated though: e.g. calls to shuffle() on the array successfully animate the changes. This used to work fine on macOS 14, but stopped working on macOS 15. I created a very simple project to reproduce the issue: import SwiftUI @main struct TestApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct IdentifiableItem: Identifiable { let id = UUID() var name: String { "Item \(id)" } } struct ContentView: View { @State var items: [IdentifiableItem] = [ IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), IdentifiableItem(), ] var body: some View { List { ForEach(items) { item in Text(item.name) } } Button("Add Item") { withAnimation { items.insert(IdentifiableItem(), at: 0) } } Button("Shuffle Items") { withAnimation { items.shuffle() } } } } How to reproduce Copy the code below in an Xcode project. Run it on macOS 15. Hit the "Add Item" button Expected: A new item is inserted with animation. Result: A new item is inserted without animation. How to prove this is a regression Follow the same steps above but run on macOS 14. A new item is inserted with animation.

I am using WebView and WebPage to display web pages. Some web pages have content fixed to the top of the screen (like apple.com). When this happens, content is under the status bar (like menu buttons), and I cannot tap them. My work around is to put the WebView in a VStack with the top being Color.clear.frame(height: 44). It isn't very elegant, especially since it is applied to all pages and not just pages with fixed content at the top. Is there a more Apple-y way to solve this? For example, Safari seems to detect these situations and puts something like Color.clear.frame(height: 44) in those cases but not other cases. Here is sample code: import SwiftUI import WebKit struct ContentView: View { @State private var page: WebPage init() { let configuration = WebPage.Configuration() page = WebPage(configuration: configuration) let url = URL(string: "https://www.apple.com")! let request = URLRequest(url: url) page.load(request) } var body: some View { WebView(page) } } Here is a screenshot of Apple's page in WebView with the menu Here is a screenshot of Apple's page in Safari. It appears to have inserted a spacer frame at the top for Apple's page (but not, for example, my own web site which doesn't have this problem).

I’ve been trying to set up a UIDocument and override writeContents(...). This works correctly in older projects, but I haven’t been able to get it working in my new iOS 26 app using Swift 6. To troubleshoot, I tested the Particles demo and successfully overrode writeContents there. However, as soon as I switch that project to iOS 26 and Swift 6, calling save; which triggers writeContents, causes the same crash. override public func writeContents( _ data: Any, to url: URL, for _: UIDocument.SaveOperation, originalContentsURL _: URL?, ) throws { ... } Thread 10 Queue : UIDocument File Access (serial)

Is anyone else getting new warning about menu items with submenus when running on Tahoe? I'm getting big performance problems using my menu as well as seeing these messages and I'm wondering if there's a connection. My app is faceless with a NSStatusItem with an NSMenu. Specifically it's my own subclass of NSMenu where I have a lot of code to manage the menu's dynamic behavior. This code is directly in the menu subclass instead of in a controller because the app I forked had it this way, a little wacky but I don't see it being a problem. A nib defines the contents of the menu, and it's instantiated manually with code like: var nibObjects: NSArray? = [] guard let nib = NSNib(nibNamed: "AppMenu", bundle: nil) else { ... } guard nib.instantiate(withOwner: owner, topLevelObjects: &nibObjects) else { ... } guard let menu = nibObjects?.compactMap({ $0 as? Self }).first else { ... } Within that nib.instantiate call I see a warning logged that seems new to Tahoe, before the menu's awakeFromNib is called, that says (edited): Internal inconsistency in menus - menu <NSMenu: 0x6000034e5340> believes it has <My_StatusItem_App.AppMenu: 0x7f9570c1a440> as a supermenu, but the supermenu does not seem to have any item with that submenu My_StatusItem_App.AppMenu: 0x7f9570c1a440 is my menu belonging to the NSStatusItem, NSMenu: 0x6000034e5340 is the submenu of one of its menu items. At a breakpoint in the NSMenu subclass's awakeFromNib I print self and see clear evidence of the warning's incorrectness. Below is a snippet of the console including the full warning, only edited for clarity and brevity. It shows on line 32 menu item with placeholder title "prototype batch item" that indeed has that submenu. Internal inconsistency in menus - menu <NSMenu: 0x6000034e5340> Title: Supermenu: 0x7f9570c1a440 (My StatusItem App), autoenable: YES Previous menu: 0x0 (None) Next menu: 0x0 (None) Items: ( "<NSMenuItem: 0x6000010e4fa0 Do The Thing Again, ke mask='<none>'>", "<NSMenuItem: 0x6000010e5040 Customize\U2026, ke mask='<none>'>", "<NSMenuItem: 0x6000010e50e0, ke mask='<none>'>" ) believes it has <My_StatusItem_App.AppMenu: 0x7f9570c1a440> Title: My StatusItem App Supermenu: 0x0 (None), autoenable: YES Previous menu: 0x0 (None) Next menu: 0x0 (None) Items: ( ) as a supermenu, but the supermenu does not seem to have any item with that submenu (lldb) po self <My_StatusItem_App.AppMenu: 0x7f9570c1a440> Title: My StatusItem App Supermenu: 0x0 (None), autoenable: YES Previous menu: 0x0 (None) Next menu: 0x0 (None) Items: ( "<NSMenuItem: 0x6000010fd7c0 About My StatusItem App\U2026, ke mask='<none>', action: showAbout:, action image: info.circle>", "<NSMenuItem: 0x6000010fd860 Show Onboarding Window\U2026, ke mask='Shift', action: showIntro:>", "<NSMenuItem: 0x6000010fd900 Update Available\U2026, ke mask='<none>', action: installUpdate:, standard image: icloud.and.arrow.down, hidden>", "<NSMenuItem: 0x6000010e46e0, ke mask='<none>'>", "<NSMenuItem: 0x6000010e4780 Start The Thing, ke mask='<none>', action: startTheThing:>", "<NSMenuItem: 0x6000010e4dc0 \U2318-\U232b key detector item, ke mask='<none>', view: <My_StatusItem_App.KeyDetectorView: 0x7f9570c1a010>>", "<NSMenuItem: 0x6000010e4e60, ke mask='<none>'>", "<NSMenuItem: 0x6000010e4f00 saved batches heading item, ke mask='<none>', view: <NSView: 0x7f9570b4be10>, hidden>", "<My_StatusItem_App.BatchMenuItem: 0x6000016e02c0 prototype batch item, ke mask='<none>', action: replaySavedBatch:, submenu: 0x6000034e5340 ()>", "<NSMenuItem: 0x6000010f7d40, ke mask='<none>'>", "<My_StatusItem_App.ClipMenuItem: 0x7f956ef14fd0 prototype copy clip item, ke mask='<none>', action: copyClip:>", "<NSMenuItem: 0x6000010fa620 Settings\U2026, ke='Command-,', action: showSettings:>", "<NSMenuItem: 0x6000010fa6c0, ke mask='<none>'>", "<NSMenuItem: 0x6000010fa760 Quit My StatusItem App, ke='Command-Q', action: quit:>" ) Is this seemingly incorrect inconsistency message harmless? Am I only grasping at straws to think it has some connection to the performance issues with this menu?

is there anything I can do about this? It's in a navigation controller, and I get a lot of these when I pop and push. eventually it causes glitches with zoom animations making for some really loopy zooms. I posted a movie to FB20439774. If there's anything I can do to fix it would be great. Unable to simultaneously satisfy constraints.

How can I correctly display the cursor using a custom keyboard in SwiftUI without using UIKit? Currently, I'm encountering a conflict between the custom keyboard and the system keyboard in SwiftUI, resulting in both keyboards being displayed simultaneously. If I disable the system keyboard and then handle the custom keyboard, the cursor disappears. How can I resolve this issue?it?

I have an app where I create UIToolbars and add them to UIViews programatically. I've never used autolayout for anything, I've never assigned any constraints to anything, etc. This worked fine pre-iOS 26. Now I'm trying to build for iOS 26 (liquid glass) and my toolbars are spamming my debug pane with hundreds of lines of autolayout warnings. Here are some key phrases from the warnings: Unable to simultaneously satisfy constraints. Will attempt to recover by breaking constraint Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) Does anybody know what happened and how I can get it to stop? The way things are, I can't use the debug pane for anything because of this spam.

When a UIVisualEffect with glass effect view is added with opacity 0, it remains hidden as expected. But when changing it back to 1 should make it visible, but currently it stays hidden forever. The bug is only reproducible on iOS 26.1 and iOS 26.2. It does not happen on iOS 26.0. The issue is also not reproducible with UIBlurEffect. Only happens for Glass effect Here is the repro link

What is the correct way to implement scrolling in a looong list that uses ScrollView and LazyVstack Imagine I have some api that returns a longs list of comments with replies The basic usecase is to scroll to the bottom(to the last comment) Most of the time this works fine But, imagine some of the comments have many replies like 35 or more (or even 300) User expands replies for the first post, then presses scroll to bottom. The scrollbar reaches the bottom and I see the blank screen. Sometimes the scrollbar may jump for a while before lazyvstack finishes loading or until I manually scroll up a bit or all the way up and down What should I do in this case? Is this the swiftui performance problem that has no cure? Abstract example: ScrollViewReader { proxy in ScrollView { LazyVStack { ForEach(comments) { comment in CommentView(comment: comment) .id("comment-\(comment.id)") } } } } struct CommentView: View { let comment: Comment @State var isExpanded = false var body: some View { VStack { Text(comment.text) if isExpanded { RepliesView(replies: comment.replies) // 35-300+ replies } } } } ... scroll proxy.scrollTo("comment-\(lastComment.id)", anchor: .bottom)

Hello! I'm creating a settings page for my app and I want it to look as native as possible. I want to know if it's possible to add constraints that make the second label go to the bottom when the text size gets really large (see Picture1) instead of having to force it to be on the right (see Picture 2). I've left my constraint code for this cell down below, too. I'm still learning constraints and best practices, so if there's any feedback, I'd love to hear it. Thank you! Picture 1 Picture 2 - (void) setConstraints { [NSLayoutConstraint activateConstraints:@[ // Cell Title Label [self.themeColorLabel.leadingAnchor constraintEqualToAnchor:self.contentView.layoutMarginsGuide.leadingAnchor], [self.themeColorLabel.trailingAnchor constraintEqualToAnchor:self.contentView.layoutMarginsGuide.trailingAnchor], [self.themeColorLabel.topAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.topAnchor], [self.themeColorLabel.bottomAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.bottomAnchor], // Selected Theme Color Label [self.selectedColorLabel.trailingAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.trailingAnchor], [self.selectedColorLabel.topAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.topAnchor], [self.selectedColorLabel.bottomAnchor constraintEqualToAnchor: self.contentView.layoutMarginsGuide.bottomAnchor], ]]; }

iOS simulator version 18.0+ I have a demo like this: Menu { Button { } label: { Text("Option 1") Image(systemName: "star") } Button { } label: { Text("Option 2") Image(systemName: "star") } } label: { Text("Menu") } And I used the tool Accessibility Inspector to modify the text size. Case 1: We could see the option title and the star icon. Case 2: But we could not see the icon, only the option title here Is this by design from Apple? Or does this need to be fixed? Does anyone know about my question?

I have a SwiftUI app. It fetches records through CoreData. And I want to show some records on a widget. I understand that I need to use AppGroup to share data between an app and its associated widget. import Foundation import CoreData import CloudKit class DataManager { static let instance = DataManager() let container: NSPersistentContainer let context: NSManagedObjectContext init() { container = NSPersistentCloudKitContainer(name: "DataMama") container.persistentStoreDescriptions = [NSPersistentStoreDescription(url: FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: group identifier)!.appendingPathComponent("Trash.sqlite"))] container.loadPersistentStores(completionHandler: { (description, error) in if let error = error as NSError? { print("Unresolved error \(error), \(error.userInfo)") } }) context = container.viewContext context.automaticallyMergesChangesFromParent = true context.mergePolicy = NSMergePolicy(merge: .mergeByPropertyObjectTrumpMergePolicyType) } func save() { do { try container.viewContext.save() print("Saved successfully") } catch { print("Error in saving data: \(error.localizedDescription)") } } } // ViewModel // import Foundation import CoreData import WidgetKit class ViewModel: ObservableObject { let manager = DataManager() @Published var records: [Little] = [] init() { fetchRecords() } func fetchRecords() { let request = NSFetchRequest<Little>(entityName: "Little") do { records = try manager.context.fetch(request) records.sort { lhs, rhs in lhs.trashDate! < rhs.trashDate! } } catch { print("Fetch error for DataManager: \(error.localizedDescription)") } WidgetCenter.shared.reloadAllTimelines() } } So I have a view model that fetches data for the app as shown above. Now, my question is how should my widget get data from CoreData? Should the widget get data from CoreData through DataManager? I have read some questions here and also read some articles around the world. This article ( https://dev.classmethod.jp/articles/widget-coredate-introduction/ ) suggests that you let the Widget struct access CoreData through DataManager. If that's a correct fashion, how should the getTimeline function in the TimelineProvider struct get data? This question also suggests the same. Thank you for your reading my question.

I’m building a photo‑gallery view that mimics the iOS Photos app when it’s zoomed in to the maximum level: all years are displayed at once, with roughly 400 tiny thumbnails per page. The user experience of the system app is that the view is instantly visible, and scrolling keeps thumbnails instantly appearing. I’ve already tried fetching thumbnails with PHImageManager and PHCachingImageManager, requesting the .fastFormat representation. However, the thumbnails still take several seconds to load, so the scrolling experience is noticeably laggy compared to the system app. Is there another approach or technique—perhaps a different caching strategy, pre‑fetching, or a lower‑level API—that would allow me to retrieve and display thumbnails as quickly (or faster) than the native Photos app? Any guidance or code snippets would be greatly appreciated.

I tried to narrow down the y-axis and use the clipped() to crop the excess. However, the clipped portion is too small, causing some of the chart to render above the x-axis. Is there any way to fix this, or any way to have the framework automatically set the y-axis range based on the data?

Hello, I'm having a problem with the .glasseffect modifier in a view of a SwiftUI application. I have a list that starts with a static element, followed by several dynamic entries, and then another static element. I've applied the .glasseffect modifier to all the elements, and it works fine except for the first static element. I think I've figured out what's causing it. This element contains two date pickers, and if I comment one out, it works. As soon as both are present, I get a BAD_ACCESS_ERROR. Oddly enough, this only happens on the tablet. Everything runs normally in the simulator. If I remove the .glassmodifier and use a normal background, it still works. Is this a bug, or is it against Liquid Glass to have two date pickers in a stack and then use the .glasseffect modifier?
