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 am trying to learn Xcode and swift ui for a class project but the attribute inspector just does not show up, I can have the simulator open or closed I click on it nothing works. I feel so stupid. I suppose you don't need it but it helps a lot. anyone have any trouble shooting that could help?

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.

I'm adapting for iOS 26, and I found that when pressing and slowly swiping the screen, the section header near the bottom of the navigation bar in the tableview flickers frequently. How can I fix this issue? Please view the video in the github project: issue.mp4

UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom]; backBtn.frame = CGRectMake(0, 0, 44, 44); [backBtn setImage:[UIImage imageNamed:@"back"] forState:UIControlStateNormal]; [backBtn addTarget:self action:@selector(gotoBack) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithCustomView:backBtn]; // backItem.hidesSharedBackground = YES; // backItem.tintColor = [UIColor redColor]; self.navigationItem.leftBarButtonItem = backItem; I am using Xcode 26, which is compatible with iOS 26. After I set up the back button of the navigation bar, why are the background colors of the back buttons on some pages gray? When I pushed the new page, after popping back to the current page, the buttons with the gray background turned back to the white background. This issue will also affect the rightBarButtonItem.

The latest iPhone model is unable to retrieve the Wi-Fi information it has connected to. The phone's operating system is iOS 26.1, and location permission has also been granted. "Access Wi-Fi Information" is also configured in the same way The following is the code I used to obtain Wi-Fi information: func getCurrentWiFiInfo() -> String? { guard let interfaces = CNCopySupportedInterfaces() as? [String] else { return nil } for interface in interfaces { guard let info = CNCopyCurrentNetworkInfo(interface as CFString) as? [String: Any] else { continue } if let ssid = info[kCNNetworkInfoKeySSID as String] as? String, !ssid.isEmpty { return ssid } } return nil }

My app uses SwiftUI Map and draws Markers, MapPolyline and MapPolygons over it. These all work on actual devices. On the iOS 26.0.1 Simulator running on macOS 26.0.1 Polylines and Polygons do now show. Do others see the same thing?

When I use the .zoom transition in a navigation stack, I get a glitch when interrupting the animation by swiping back before it completes. When doing this, the source view disappears. I can still tap it to trigger the navigation again, but its not visible on screen. This seems to be a regression in iOS 26, as it works as expected when testing on iOS 18. Has someone else seen this issue and found a workaround? Is it possible to disable interrupting the transition? Filed a feedback on the issue FB19601591 Screen recording: https://share.icloud.com/photos/04cio3fEcbR6u64PAgxuS2CLQ Example code @State var showDetail = false @Namespace var namespace var body: some View { NavigationStack { ScrollView { showDetailButton } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline) .navigationDestination(isPresented: $showDetail) { Text("Detail") .navigationTransition(.zoom(sourceID: "zoom", in: namespace)) } } } var showDetailButton: some View { Button { showDetail = true } label: { Text("Show detail") .padding() .background(.green) .matchedTransitionSource(id: "zoom", in: namespace) } } }

Hi I have a NSTextView set as the document of a NSScrollView scrollView.documentView = textView I want to programatically scroll to a specific offset in the scrollView. I use the following function and it jumps to the right location: scrollView.documentOffset = offset However I would like to animate the scrolling. Any suggestions? Also to mention, I have not flipped the coordinates of the NSTextView Thanks Reza

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.

The issue can be reproduced using the simplest code. In Xcode 26 + iOS 26, when a UIBarButtonItem is created using a UIImage, it consistently prints numerous constraint conflict warnings to the console. Below is my test code and the console warnings: let btn = UIBarButtonItem(systemItem: .trash) self.toolbarItems = [btn] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( "<NSLayoutConstraint:0x1083b4550 _TtC5UIKitP33_DDE14AA6B49FCAFC5A54255A118E1D8713ButtonWrapper:0x108374e00.width == _UIButtonBarButton:0x1083e8000.width (active)>", "<NSLayoutConstraint:0x1083b4aa0 'IB_Leading_Leading' H:|-(2)-[_UIModernBarButton:0x103ac62e0] (active, names: '|':_UIButtonBarButton:0x1083e8000 )>", "<NSLayoutConstraint:0x1083b4af0 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x103ac62e0]-(2)-| (active, names: '|':_UIButtonBarButton:0x1083e8000 )>", "<NSLayoutConstraint:0x1083b4fa0 'UIView-Encapsulated-Layout-Width' _TtC5UIKitP33_DDE14AA6B49FCAFC5A54255A118E1D8713ButtonWrapper:0x108374e00.width == 0 (active)>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x1083b4af0 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x103ac62e0]-(2)-| (active, names: '|':_UIButtonBarButton:0x1083e8000 )> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

I need the user to input an emoji but not other characters. I'd like to be able to use an emoji keyboard similar to the one in the Reminders app. How can I do this?

.popover(isPresented: modifier doesn't work on Mac Catalyst when attached to the item in the toolbar. The app crashes on button click, when trying to present the popover. iOS 26 RC (macOS 26 RC) Feedback ID - FB20145491 import SwiftUI struct ContentView: View { @State private var isPresented: Bool = false var body: some View { NavigationStack { Text("Hello, world!") .toolbar { ToolbarItem(placement: .automatic) { Button(action: { self.isPresented.toggle() }) { Text("Toggle popover") } .popover(isPresented: $isPresented) { Text("Hello, world!") } } } } } } #Preview { ContentView() }

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.

Do you guys know how to fix the render of the text in the accessory view ? If I force the color of text to be .black it work but it will break dark mode, but forcing it .black : .white on color scheme changes makes white to still adapt to what is behind it I have noticed that Apple Music doesn’t have that artifact and it seems to break when images are behind the accessory view // MARK: - Next Routine Accessory @available(iOS 26.0, *) struct NetxRoutinesAccessory: View { @ObservedObject private var viewModel = RoutineProgressViewModel.shared @EnvironmentObject var colorSchemeManager: ColorSchemeManager @EnvironmentObject var routineStore: RoutineStore @EnvironmentObject var freemiumKit: FreemiumKit @ObservedObject var petsStore = PetsStore.shared @Environment(\.colorScheme) private var colorScheme // Tab accessory placement environment @Environment(\.tabViewBottomAccessoryPlacement) private var accessoryPlacement // Navigation callback var onTap: (() -> Void)? @State private var isButtonPressed = false /// Explicit black for light mode, white for dark mode private var textColor: Color { colorScheme == .dark ? .trueWhite : .trueBlack } /// Returns true when the accessory is in inline/minimized mode private var isInline: Bool { accessoryPlacement == .inline } var body: some View { accessoryContent() .onTapGesture { onTap?() } } private func accessoryContent() -> some View { HStack(spacing: 12) { // Content with smooth transitions VStack(alignment: .leading, spacing: 2) { if viewModel.totalTasks == 0 { Text(NSLocalizedString("Set up routines", comment: "Routines empty state")) .font(.subheadline.weight(.medium)) .foregroundColor(textColor) } else if let next = viewModel.nextRoutineTask() { HStack(spacing: 4) { Text(NSLocalizedString("Next", comment: "Next routine prefix")) .font(.caption) .foregroundColor(textColor) Text("•") .font(.caption) .foregroundColor(textColor) Text(next.routine.name) .font(.subheadline.weight(.medium)) .foregroundColor(textColor) .lineLimit(1) } .id("routine-\(next.routine.id)-\(next.time)") .transition(.opacity.combined(with: .move(edge: .leading))) HStack(spacing: 4) { Text(viewModel.petNames(for: next.routine.petIDs)) .font(.caption) .foregroundColor(textColor) Text("•") .font(.caption) .foregroundColor(textColor) Text(Routine.displayTimeFormatter.string(from: next.time)) .font(.caption.weight(.medium)) .foregroundColor(colorSchemeManager.accentColor ?? .blue) } .id("time-\(next.routine.id)-\(next.time)") .transition(.opacity.combined(with: .move(edge: .leading))) } else { // All tasks completed Text(NSLocalizedString("All done for today!", comment: "All routines completed")) .font(.subheadline.weight(.medium)) .foregroundColor(textColor) .transition(.opacity.combined(with: .scale)) Text("\(viewModel.completedTasks)/\(viewModel.totalTasks) " + NSLocalizedString("tasks", comment: "Tasks count suffix")) .font(.caption) .foregroundColor(textColor) } } .animation(colorSchemeManager.reduceMotion ? nil : .snappy(duration: 0.3), value: viewModel.completedTasks) .animation(colorSchemeManager.reduceMotion ? nil : .snappy(duration: 0.3), value: viewModel.progress) } .padding() .contentShape(.rect) .animation(colorSchemeManager.reduceMotion ? nil : .snappy(duration: 0.35), value: viewModel.completedTasks) } }

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.

I'm developing a rhythm game for iOS which has four buttons spanning the width of the screen in portrait. I noticed that my testers were having some missed inputs on the buttons on the left and right due to the fact that iOS, by default, tries to ignore accidental touches on the edges of the screen. So I enabled "Defer System Gestures" on the left and right edges, but then quickly started to notice a new, very specific, issue. Description of the issue If you have finger #1 touching and holding anywhere in the middle of the screen, and finger #2 touches on the far right or left edge of the screen just below the horizontal position of finger #1, those touches are inconsistently not recognized. If finger #1 is not present, this issue does not occur. If finger #2 is above or well below finger #1, this issue also does not occur. A dead zone is created on the right and left edges of the screen just below the horizontal position of the first touch. Here is a rough representative example of where touches #1 and #2 need to be for this issue to manifest, in case the text above is not clear. |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| It just so happens that this issue is causing major usability problems with my game, as it results in what the user sees as sporadic and inconsistent response when the game calls for two notes to be played at the same time. Steps to recreate the issue Here are the steps if you want to recreate the problem yourself using the "Create New Gesture" pane in "Assistive Touch" (Note that this problem is not specific to the Settings app, but rather is an issue across the system—however this panel defers system gestures and shows where touches are being read, so it is a great place to demonstrate): (1) Go to Settings &gt; Accessibility &gt; Touch &gt; Assistive Touch &gt; Create New Gesture...; (2) With one finger, touch the middle of the screen and hold it through step 3; (3) With a second finger, tap 4 times along the right (or left) edge of the screen in the following places: (a) well above the vertical position of the first touch, (b) just above the vertical position of the first touch, (c) just below the vertical position of the first touch, and (d) well below the vertical position of the first touch; (4) Notice how, more than half the time, touch (c) does not register. I have found that this problem is more replicatable when the first touch is on the lower half of the screen, but I have been able to replicate it when the finger is higher as well, just not as consistently. Here are the four positions described in the steps above: Position a: both touches register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position b: both touches usually register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position c: only touch 1 registers |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| Position d: both touches register |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9; 1&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9;&amp;#9;| |&amp;#9;&amp;#9;&amp;#9; 2| Is there anything I can do to resolve this behavior? My app requires gesture deferment to be on for the expected experience by the user, and this bug is causing other issues for my testers that kind of need to be resolved before I can confidently release the game.

Issue: The search functionality in FamilyActivityPicker has disappeared on iPadOS 26.0+. This feature was working in previous versions but is now missing. Framework: FamilyControls Expected: Search bar should be available in FamilyActivityPicker to help users find apps quickly. Actual: Search functionality is completely missing. Impact: Makes app selection difficult for users with many installed apps. Is this a known issue? If it's a bug, please address it in an upcoming update. If intentional, guidance on alternatives would be appreciated. Thank you.

We're using XCode 26.1.1 We do not have resource to adopt Liquid Glass design. Hence, we are using the following workaround <key>UIDesignRequiresCompatibility</key> <true/> This is our Storyboard. Pre XCode 26 Before XCode 26.1.1, the bottom toolbar looks great. In XCode 26 However, in XCode 26.1.1, the bottom toolbar buttons seems to "Squish together". Do anyone have any idea, how I can make UIToolbar works by enabling UIDesignRequiresCompatibility? Thanks.

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
