At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for UI Frameworks. How would you recommend developers start adopting the new design? Start by focusing on the foundational structural elements of your application, working from the "top down" or "bottom up" based on your application's hierarchy. These structural changes, like edge-to-edge content and updated navigation and controls, often require corresponding code modifications. As a first step, recompile your application with the new SDK to see what updates are automatically applied, especially if you've been using standard controls. Then, carefully analyze where the new design elements can be applied to your UI, paying particular attention to custom controls or UI that could benefit from a refresh. Address the large structural items first then focus on smaller details is recommended. Will we need to migrate our UI code to Swift and SwiftUI to adopt the new design? No, you will not need to migrate your UI code to Swift and SwiftUI to adopt the new design. The UI frameworks fully support the new design, allowing you to migrate your app with as little effort as possible, especially if you've been using standard controls. The goal is to make it easy to adopt the new design, regardless of your current UI framework, to achieve a cohesive look across the operating system. What was the reason for choosing Liquid Glass over frosted glass, as used in visionOS? The choice of Liquid Glass was driven by the desire to bring content to life. The see-through nature of Liquid Glass enhances this effect. The appearance of Liquid Glass adapts based on its size; larger glass elements look more frosted, which aligns with the design of visionOS, where everything feels larger and benefits from the frosted look. What are best practices for apps that use customized navigation bars? The new design emphasizes behavior and transitions as much as static appearance. Consider whether you truly need a custom navigation bar, or if the system-provided controls can meet your needs. Explore new APIs for subtitles and custom views in navigation bars, designed to support common use cases. If you still require a custom solution, ensure you're respecting safe areas using APIs like SwiftUI's safeAreaInset. When working with Liquid Glass, group related buttons in shared containers to maintain design consistency. Finally, mark glass containers as interactive. For branding, instead of coloring the navigation bar directly, consider incorporating branding colors into the content area behind the Liquid Glass controls. This creates a dynamic effect where the color is visible through the glass and moves with the content as the user scrolls. I want to know why new UI Framework APIs aren’t backward compatible, specifically in SwiftUI? It leads to code with lots of if-else statements. Existing APIs have been updated to work with the new design where possible, ensuring that apps using those APIs will adopt the new design and function on both older and newer operating systems. However, new APIs often depend on deep integration across the framework and graphics stack, making backward compatibility impractical. When using these new APIs, it's important to consider how they fit within the context of the latest OS. The use of if-else statements allows you to maintain compatibility with older systems while taking full advantage of the new APIs and design features on newer systems. If you are using new APIs, it likely means you are implementing something very specific to the new design language. Using conditional code allows you to intentionally create different code paths for the new design versus older operating systems. Prefer to use if #available where appropriate to intentionally adopt new design elements. Are there any Liquid Glass materials in iOS or macOS that are only available as part of dedicated components? Or are all those materials available through new UIKit and AppKit views? Yes, some variations of the Liquid Glass material are exclusively available through dedicated components like sliders, segmented controls, and tab bars. However, the "regular" and "clear" glass materials should satisfy most application requirements. If you encounter situations where these options are insufficient, please file feedback. If I were to create an app today, how should I design it to make it future proof using Liquid Glass? The best approach to future-proof your app is to utilize standard system controls and design your UI to align with the standard system look and feel. Using the framework-provided declarative API generally leads to easier adoption of future design changes, as you're expressing intent rather than specifying pixel-perfect visuals. Pay close attention to the design sessions offered this year, which cover the design motivation behind the Liquid Glass material and best practices for its use. Is it possible to implement your own sidebar on macOS without NSSplitViewController, but still provide the Liquid Glass appearance? While technically possible to create a custom sidebar that approximates the Liquid Glass appearance without using NSSplitViewController, it is not recommended. The system implementation of the sidebar involves significant unseen complexity, including interlayering with scroll edge effects and fullscreen behaviors. NSSplitViewController provides the necessary level of abstraction for the framework to handle these details correctly. Regarding the SceneDelagate and scene based life-cycle, I would like to confirm that AppDelegate is not going away. Also if the above is a correct understanding, is there any advice as to what should, and should not, be moved to the SceneDelegate? UIApplicationDelegate is not going away and still serves a purpose for application-level interactions with the system and managing scenes at a higher level. Move code related to your app's scene or UI into the UISceneDelegate. Remember that adopting scenes doesn't necessarily mean supporting multiple scenes; an app can be scene-based but still support only one scene. Refer to the tech note Migrating to the UIKit scene-based life cycle and the Make your UIKit app more flexible WWDC25 session for more information.

I have a borderless NSWindow with transparent background floating at Dock level and with collectionBehavior set to NSWindowCollectionBehaviorCanJoinAllSpaces. To render its background I was using an NSVisualEffectView, but, with the introduction of Liquid Glass, I decided to replace it with a NSGlassEffectView on Tahoe. On macOS 26.0 and 26.1 all works fine: my window's background is correctly rendered and updated. On macOS 26.2 this is not so: the background seems cached and doesn't update if I move my window or if I drag some other window underneath it. My window's movable property is set to NO (and I need this to be so): dragging is implemented by handling mouseDown, mouseDragged, and mouseUp events. Just to experiment, I tried setting movable and movableByWindowBackground both to YES. In this case, the NSGlassEffectView is correctly updated if I move the window itself, but doesn't change if I move other windows underneath it. Has anybody experienced a similar problem on maOS 26.2? If so, is there a way to solve it? Thanks, Marco

Hello! What UIKit API enables you to add a view below the navigation bar and extend the scroll edge effect below it in iOS 26? safeAreaBar is how you do it in SwiftUI but I need to achieve this design in my UIKit app (which has a collection view in a view controller in a navigation controller). struct ContentView: View { let segments = ["First", "Second", "Third"] @State private var selectedSegment = "First" var body: some View { NavigationStack { List(0..<50, id: \.self) { i in Text("Row \(i + 1)") } .safeAreaBar(edge: .top) { Picker("Segment", selection: $selectedSegment) { ForEach(segments, id: \.self) { Text($0) } } .pickerStyle(.segmented) .padding(.horizontal) .padding(.bottom, 8) } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline) } } }

Since iOS 26.0, the Control Center layout consistently resets in landscape orientation after certain system events. This issue is still present in the official public release of iOS 26.2. The reset occurs without a visible reboot and appears to be triggered by a background SpringBoard termination (jetsam) during charging idle maintenance windows (typically overnight while the device is plugged in). After SpringBoard relaunches: • The portrait Control Center layout is restored correctly • The landscape Control Center layout is reinitialized using the default order This indicates a state restoration failure rather than a user configuration or sync issue. ⸻ Steps to Reproduce: Use an iPhone 15 Pro running iOS 26.0, 26.1, or 26.2 Manually reorder Control Center controls Leave the device plugged in and idle overnight During charging idle, SpringBoard is terminated in the background due to memory pressure (no visible reboot) Open Control Center the next day: • Portrait layout is preserved • Landscape layout has reverted to default ⸻ Expected Result: Both portrait and landscape Control Center layouts should persist across SpringBoard restarts caused by jetsam or memory pressure, including during charging idle maintenance. ⸻ Actual Result: After SpringBoard relaunch: • Portrait layout is restored correctly • Landscape layout is lost and recreated using the default configuration ⸻ Analytics / Logs (relevant excerpt): Process: SpringBoard Case Type: MemoryResourceException Subtype: MREExceptionFatalLimitActive This occurs during charging idle and does not require a user-initiated reboot. ⸻ Additional Observations: • Issue does not occur when the device is idle overnight without charging • Manual reordering works correctly until the next SpringBoard jetsam • Resetting settings, disabling iCloud sync, or reinstalling iOS does not resolve the issue • This behavior has persisted across multiple major and minor releases, indicating a regression or unresolved bug ⸻ Suspected Root Cause: Incomplete state restoration in ControlCenterKit after SpringBoard relaunch following jetsam during charging idle. Portrait state is restored; landscape state falls back to default.

Filed in Feedback as FB20772137 Zoom transition originating from inside tabViewBottomAccessory, when the binding passed to fullScreenCover's item is a Binding other than a "$-synthesized" binding, the animation fails with the following error (and crucially fails to perform the desired animation): Starting a zoom transition from a nil view will trigger a fallback transition. To get the best possible teansition, be sure to provide a view that's visible and in a window. What I want to do is pass a binding to a property inside an ObservableObject (or @Observable, but it doesn't matter) to hold the item representing the presentation. But this stopped working as of 26.1b4. It worked in 26.1b3 and in 26.0 (and 26.0.1) Here's the gist of code that will reproduce the issue (I've omitted irrelevant details in the interest of brevity): struct ContentView: View { @Binding var presentation: PresentationDestination? @Namespace private var animation var body: some View { // Omitted TabView stuff… .tabViewBottomAccessory { miniPlayer .matchedTransitionSource( id: "player", in: animation ) } .fullScreenCover( item: $presentation, content: { _ in fullScreenPlayer .navigationTransition( .zoom( sourceID: "player", in: animation ) ) }) } As you can see, ContentView takes a Binding to the presentation, but it matters how this binding is constructed. This works: @State private var presentation: PresentationDestination … ContentView(presentation: $presentation) This fails (as does ObservableObject with @Published): @Observable class Router2 { var presentation: PresentationDestination? } … @State private var router2 = Router2() … ContentView(presentation: $router2.presentation) Also, this fails: @State private var presentation: PresentationDestination … ContentView( presentation: .init(get: { presentation }, set: { newValue in presentation = newValue }) ) These differences are unexpected, of course. I consider this a regression in 26.1b4 I should add that if I move the source of the transition to somewhere outside tabViewBottomAccessory things seem to work fine.

"Use location, address and addressRepresentations instead" Is it possible to know what kind of "Address" a MapItem is representing (State, County, Neighborhood etc) after a MKGeocodingRequest? Is it possible to find out the CLRegion or similar of an map item. (Now when we cannot read it from the Placemark)

Problem Description: In a SwiftUI application, I've wrapped UIKit's UIPageViewController using UIViewControllerRepresentable, naming the wrapped class PagedInfiniteScrollView. This component causes navigation bar elements (title and buttons) to disappear. This issue only occurs in Low Power Mode on a physical device. Steps to Reproduce: Enable Low Power Mode on a physical device and open the app's home page. From the home page, open a detail sheet containing PagedInfiniteScrollView. This detail page include a navigation title and a toolbar button in the top-right corner. PagedInfiniteScrollView supports horizontal swiping to switch pages. Tap the toolbar button in the top-right corner of the detail page to open an edit sheet. Without making any changes, close the edit sheet and return to the detail page. On the detail page, swipe left and right on the PagedInfiniteScrollView. Expected Result: When swiping the PagedInfiniteScrollView, the navigation title and top-right toolbar button of the detail page should remain visible. Actual Result: When swiping the PagedInfiniteScrollView, the navigation title and top-right toolbar button of the detail page disappear. import SwiftUI @main struct CalendarApp: App { var body: some Scene { WindowGroup { ContentView() } } } import SwiftUI struct ContentView: View { @State private var showDetailSheet = false @State private var currentPage: Int = 0 var body: some View { NavigationStack { Button { showDetailSheet = true } label: { Text("show Calendar sheet") } .sheet(isPresented: $showDetailSheet) { DetailSheet(currentPage: $currentPage) } } } } struct DetailSheet: View { @Binding var currentPage: Int @State private var showEditSheet = false var body: some View { NavigationStack { PagedInfiniteScrollView(content: { pageIndex in Text("\(pageIndex)") .frame(width: 200, height: 200) .background(Color.blue) }, currentPage: $currentPage) .sheet(isPresented: $showEditSheet, content: { Text("edit") }) .navigationTitle("Detail") .navigationBarTitleDisplayMode(.inline) .toolbar { ToolbarItemGroup(placement: .topBarTrailing) { Button { showEditSheet = true } label: { Text("Edit") } } } } } } import SwiftUI import UIKit struct PagedInfiniteScrollView<Content: View>: UIViewControllerRepresentable { typealias UIViewControllerType = UIPageViewController let content: (Int) -> Content @Binding var currentPage: Int func makeCoordinator() -> Coordinator { Coordinator(self) } func makeUIViewController(context: Context) -> UIPageViewController { let pageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal) pageViewController.dataSource = context.coordinator pageViewController.delegate = context.coordinator let initialViewController = UIHostingController(rootView: IdentifiableContent(index: currentPage, content: { content(currentPage) })) pageViewController.setViewControllers([initialViewController], direction: .forward, animated: false, completion: nil) return pageViewController } func updateUIViewController(_ uiViewController: UIPageViewController, context: Context) { let currentViewController = uiViewController.viewControllers?.first as?

One screen in my app uses a navigation bar with some buttons added to the titleView and some buttons added as a customView of a single rightBarButtonItem. In iOS 26 (beta 9), if I switch to the home screen and back again, the titleView and rightBarButtonItem disappear and an overflow button (three dots) appears instead. Nothing happens when I click the overflow button. Here's a screen capture: https://youtu.be/tthRnMz98kA This also happens when I switch to another app, when I rotate the device or when I resize the app window. In all cases, there is enough room to show all the buttons, but they still disappear. I overrode the viewWillTransition function in my view controller and logged when that runs. I can see that if I switch to the home screen and back again before that runs (within one or two seconds), there's no problem. But once that runs, the navigation bar items disappear and the overflow button appears. I have not done anything to set up the overflow button and don't have any need to use it. The documentation about it isn't very detailed, but it seems like it shouldn't be used unless I add it. This wasn't a problem in iOS 18 or earlier iOS versions. Does anyone know how to stop this? BTW, I'm using Swift, but not SwiftUI.

Try this simple code: import SwiftUI import StoreKit struct ReviewView: View { @Environment(\.requestReview) var requestReview var body: some View { Button("Leave a review") { requestReview() } } } When the Review Alert shows, the "Not Now" button is disabled for some reason!? It was always tappable in all iOS versions that I remember. And there is no way to opt out, unless the user taps on the stars first. Is it a bug or a feature? Thanks for looking into it!

Hi, I faced with the issue on iOS 26.1 with PHPickerViewController. After first selection I save assetIdentifier of PHPickerResult for images. next time I open the picker I expect to have the images selected based on assetIdentifier Code: var config = PHPickerConfiguration(photoLibrary: .shared()) config.selectionLimit = 10 config.filter = .images config.preselectedAssetIdentifiers = images.compactMap(\.assetID) let picker = PHPickerViewController(configuration: config) picker.delegate = self present(picker, animated: true) But on iOS 26.1 they aren't selected. On lower iOS version all works fine. Does anybody faced with similar issue?

I have installed the latest beta on my iPad , iPadOS 16.1 (20B5050f) On running in app in Playgrounds that has a TextField, external keyboard input do not seem to be working. Tapping on the Text field inserts the cursor but no text can be entered on my external keyboard. (TextEditor field also do not work) Tested with both a Smart Keyboard and a Magic Keyboard. The keyboard works to enter the code in playgrounds, so it is not a keyboard connection issue. Disconnecting the keyboard, the onscreen keyboard is displayed and works correctly. Is this a Playgrounds issue or an iPadOS 16.1 issue or a compatibility issue with Playgrounds & iPadOS 16.1 ? import SwiftUI struct ContentView: View {     @State var field: String = "Test input"          var body: some View {         VStack {             Image(systemName: "globe")                 .imageScale(.large)                 .foregroundColor(.accentColor)             Text("Hello, world!")             TextField("", text: $field)                 .frame(height: 100)         }     } }

I've got a situation where I want the iPad to push an editing view onto the sidebar (like on iPhone) and also display a detail view (no content view). This is working great. However, I need to determine which item from a List in a NavigationSplitView has been selected and pass this to the detail view (the selection is out of scope). This works with the List selection parameter, but the item selected is ONLY selected and the child view in the NavigationLink does not get pushed, nor does the detail view get changed. I either need to figure out a way to capture the selection without the List Selection parameter (Tap Gesture?) or get the navigation to happen even when using the Selection parameter. I'd appreciate some ideas as I'm a newb just learning SwiftUI.

With iOS 26 there has been a change in behavior with Pickers in the toolbar. The Picker looks expanded unlike other views such as a Button and Menu. See screenshots below. Is this the intended behavior or a bug? (I already submitted a feedback for this at FB19276474) What Picker looks like in the toolbar: What Button looks like in the toolbar:

I have a SwiftUI recursive list, created with the (children:) initializer, just like it's shown in the code example here: https://developer.apple.com/documentation/SwiftUI/List#Creating-hierarchical-lists I would like this tree view to be searchable (i.e a user enters a query into a text field and it searches the entire tree at all levels). Displaying a search result which is not at the top level would require its parents to be programmatically expanded. How to programmatically expand certain levels of such a list?

My app doesn't respond on iPhone Air iOS 26.1. After startup, my app shows the main view with a tab bar controller containing 4 navigation controllers. However, when a second-level view controller is pushed onto any navigation controller, the UI freezes and becomes unresponsive. The iPhone simulator running iOS 26.1 exhibits the same problem. The debug profile shows CPU usage at 100%. However, other devices and simulators do not have this problem.

With iOS 26.1 we started seeing a bug that only appears on iPhone Air. This bug is visible with simulators too. I have tried so many different ways to fix the issue, but Instruments Profiler is pointing at UIKitCore. We load a tab bar, when the user attempts to switch a tab, the app hangs and never recovers. It happens right as the animation of the Glass bubble is in progress. I have tried a UIKit Tab bar, a SwiftUI Tab bar. I tore out AppDelegate and did a direct @main SwiftUI entry for my application. This issue appears with every tab bar instance I try. I attempted to disable LiquidGlass by utilizing this flag UIDesignRequiresCompatibility in my plist, but the flag seems to be ignored by the system. I am not sure what else to try. I have a trace file if that is helpful. What else can I upload? Here is what the code looks like. struct ContentView: View { @State private var selectedTab = 2 var body: some View { TabView(selection: $selectedTab) { Text("Profile") .tabItem { Label("Me", systemImage: "person") } .tag(0) Text("Training") .tabItem { Label("Training", systemImage: "calendar") } .tag(1) Text("Home") .tabItem { Label("Home", systemImage: "house") } .tag(2) Text("Goals") .tabItem { Label("Goals", systemImage: "target") } .tag(3) Text("Coach") .tabItem { Label("Coach", systemImage: "person.2") } .tag(4) } } } #Preview { ContentView() } and AppView entry point import SwiftUI @main struct RunCoachApp: App { var body: some Scene { WindowGroup { ContentView() } } }

The top toolbar looks fine, but in the bottom toolbar, one of the layers is stretched into a capsule shape instead of an ellipse. Is this intended?

I have a search field and a List of search results. As the user types in the search field, the List is updated with new results. Crucially, with each update, I want to reset the List's scroll position back to the top. To achieve this, I'm using the following .onChange() modifier along with a ScrollViewReader: .onChange(of: searchQuery) { _, newQuery in Task { searchResults = await searchLibrary(for: newQuery) scrollViewProxy.scrollTo(0, anchor: .top) } } My List uses index-based IDs, so scrolling to 0 should always go to the first item. The above code works, but crashes if searchResults is empty because there is no item in the List with an ID of 0. (As a side note, it seems rather excessive for the scrollTo() method to trigger a full-on crash just because the ID is not found; I don't think this should be anything more than a warning, or the method should throw an error that can be caught). To work around this, I added an isEmpty check, so we only attempt the scroll if the array is not empty: .onChange(of: searchQuery) { _, newQuery in Task { searchResults = await searchLibrary(for: newQuery) if !searchResults.isEmpty { scrollViewProxy.scrollTo(0, anchor: .top) } } } However, even with this check, I was seeing rare crashes in production, consistent with a race condition. My guess is that when searchResults is updated, the view is not recreated immediately, so if scrollTo() is called too quickly, the List may not yet be seeing the latest update to the searchResults array. I figured that I could try to delay the calling of scrollTo() to give the view time to update: .onChange(of: searchQuery) { _, newQuery in Task { searchResults = await searchLibrary(for: newQuery) if !searchResults.isEmpty { DispatchQueue.main.async { scrollViewProxy.scrollTo(0, anchor: .top) } } } } However, even with this, I've just received a crash report pointing to the same issue (the first in about four months). I'm not able to reproduce the bug myself – so it definitely seems like a rare race condition, probably relating to the timing of view updates. I guess, I can insert another isEmpty check before calling scrollTo(), but I'm starting to wonder if it's even possible to guarantee that the item will be in the List when scrollTo() performs its action, and because this is so hard to reproduce, I can't really test any ideas. Does anyone have any idea how (and at what point) the ScrollViewReader reads the view's current state? What's the right way to approach debugging a problem like this? Moreover, does anyone have any better suggestions about how to handle resetting the List position? The reason I want to do this is because, if the user types, scrolls a bit, and then types some more, the new results appear above the fold where the user can't see them, leading to a confusing experience. I thought about switching to the newer .scrollPosition() modifier, but that's only iOS 18+ and only for ScrollViews, not Lists. Cheers!

Using desaturated mode on an image in a widget will break any links or buttons that use the image as their 'label'. Using the following will just open the app as if there was no link at all - therefore just using the fallback userActivity handler, or any .widgetURL() urls provided. Link(destination: URL(string: "bug://never-works")!) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } The same goes for buttons: Button(intent: MyDemoIntent()) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } I've tried hacky solutions like putting the link behind the image using a ZStack, and disabling hit testing on the image, but they don't work. Anything else to try? Logged as Feedback #15152620.

When tap the Button quickly in List, the ButtonStyleConfiguration’s isPressed property don't change properly, always false. When using Button in ScrollView, the same error doesn't exist.
