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.

We have SwiftUI AttributedString with links. But these links are inaccessible via automation scripts. The text is visible to the automation scripts as XCUIElementTypeStaticText and there is no provision to access the links within. Is there any workaround available for this case ?

I am currently implementing multiple scenes in my React Native / Swift application (one scene for the phone and one scene for CarPlay). I am facing an issue where one scene renders completely white (on the iPhone) but I can see in the console that the code is running (for example if I add a console.log to the App.tsx I can see that console log happen in XCode). There are no errors when building the app in XCode, and testing with the simulator CarPlay appears to render the correct output, but there is no component being rendered on the simulated phone screen (just white).

I am very new to building apps with React Native and Swift so could do with some support.

I have an application named "XY" that has been launched in several countries. Now, I intend to launch it in Turkey, but we are facing legal issues preventing us from using "XY" as the app's display name. Following the documentation, I localized the app's display name to "ZX" for both Turkish and English (Turkey). However, when users change their device settings, they do not see an option for English (Turkey) language selection. I assumed that for Turkish users, English (Turkey) would be the default language, but this is not the case. Could someone please assist me in resolving this issue? I've investigated options for localizing the display name based on region, but it seems that this functionality isn't feasible on iOS. In contrast, it's relatively straightforward to achieve on Android platforms.

Hi guys, I’m making a simple note taking app and I want to support markdown functionality. I have tried to find libraries and many other GitHub repos but some of them are slow and some of them are very hard to implement and not very customizable. In WWDC 22 apple also made a markdown to html document app and I also looked at that code and it was awesome. It was fast and reliable (Apple btw). But the only problem I am facing is that the markdown text is on the left side and the output format is on the right in the form of html. I don’t want that I want both in the same line. In bear notes and things 3 you can write in markdown and you can see that it is converting in the same line. I have also attached example videos. So, I have markdown parser by apple but the only thing in the way is that it is converting it into a html document. Please help me with this. Also please look into the things 3 video they have also completely customized the text attributes selection menu. By default with UITextView we can only enable text attributes and it shows like this. By clicking more we get the complete formatting menu but not the slider menu which is more convenient. Please also help me this. I don’t know if I can provide apple file but it is from wwdc 22 supporting desktop class interaction

I have a UITextView being added at runtime to a UIImageView as the result of doing text recognition. It's set to be editable = NO and selectable = YES. When I set the text and select it, it asks the delegate for the menu to display via: textView:editMenuForTextInRange:suggestedActions: The suggested items contains many UIAction and UICommand objects that have private methods or do not have the destructive attribute set, yet they are destructive. Some of these are: promptForReplace: transliterateChinese: _insertDrawing: _showTextFormattingOptions: I need to return a menu that has only non-destructive commands in it. First, why isn't UITextView sending only non-destructive suggested commands when its editable is NO? Second, how can I filter the array of suggested commands when it's impossible to know if they're destructive (as some are missing that attribute)? In addition to that, even non-destructive commands are causing an unrecognized selector exception, such as the Speak command, which it is sending to my view controller instead of to the UITextView, which is the only thing that knows what the text is that it should speak.

I set UIToolbar and UIBarButtonItem to UITextField placed on Xib, but when I run it on iOS18 iPad, the following error is output to Xcode Console, and UIPickerView set to UITextField.inputView is not displayed.

Hi everyone, I believe this should be a simple and expected default behavior in a real-world app, but I’m unable to make it work: 1. I have a View (a screen/page in this case) that calls an endpoint using async/await. 2. If the endpoint hasn’t finished, but I navigate forward to a DetailView, I want the endpoint to continue fetching data (i.e., inside the @StateObject ViewModel that the View owns). This way, when I go back, the View will have refreshed with the fetched data once it completes. 3. If the endpoint hasn’t finished and I navigate back to the previous screen, I want it to be canceled, and the @StateObject ViewModel should be deinitialized. I can achieve 1 and 3 using the .task modifier, since it automatically cancels the asynchronous task when the view disappears: view .task { await vm.getData() } I can achieve 1 and 2 using a structured Task in the View (or in the ViewModel, its the same behavior), for example: .onFirstAppearOnly { Task { away vm.getData() } } onFirstAppearOnly is a custom modifier that I have for calling onAppear only once in view lifecycle. Just to clarify, dont think that part is important for the purpose of the example But the question is: How can I achieve all three behaviors? Is this really such an unusual requirement? My minimum deployment target is iOS 15, and I’m using NavigationView + NavigationLink. However, I have also tried using NavigationStack + NavigationPath and still couldn’t get it to work. Any help would be much appreciated. Thank you, folks!

I have setup the extension for replaykit successfully , the bundle id and everything is correct but still the system broadcast picker view is not showing my own app to broadcast screen content when trying to do system wide broadcast.

So I am looking to use a custom NSWindow application (so I can implement some enhanced resizing/dragging behavior which is only possible overriding NSWindow). The problem is my whole application is currently SwiftUI-based (see the project here: https://github.com/msdrigg/Roam/blob/50a2a641aa5f2fccb4382e14dbb410c1679d8b0c/Roam/RoamApp.swift). I know there is a way to make this work by dropping my @main SwiftUI app and replacing it with a SwiftUI root view hosted in a standard AppKit root app, but that feels like I'm going backwards. Is there another way to get access (and override) the root NSWindow for a SwiftUI app?

Hello, is there a way to implement Continuity Markup in our own apps? (This is what I'm talking about: https://support.apple.com/en-us/102269 , scroll down to "Use Continuity Markup"). Also, why does a QuickLook panel (QLPreviewPanel.shared()) not display the markup options when triggered from my app for png image files in my app's Group Container? Do I need to implement certain NSServicesMenuRequestor methods for that? Sadly, I could not find any docs on that. Thank you, – Matthias

SwiftUI, using LPLinkView through UIViewRepresentable. Default behavior is a long press brings up a context menu and a popover to preview content. I want to replace that default long press behavior with my own custom screen. Adding a UILongPressGestureRecognizer didn't work. Thanks!

As you can see in the screenshot, the verification popups that appear when making a StoreKit purchase cut off the buttons. When typing the code into the input field, the window will also flicker and stutter with random view refreshes. Is this something I can configure/change? It's not a very pleasant experience for making an in app purchase.

I'm trying to create a .pkg installer with productbuild/pkgbuild. But I'd also like to add my custom installer plugin to this. I'm using the following script. I'd like to add my bundle into this script. Since there are no official docs from apple how to do this nor there are a lot of updated resources, here are some things I have tried. adding the following line to Distrubtion.xml <bundle id="pluginid" path="path/to/myplugin.bundle"/> adding component tag to pkgbuild also doesn't do anything --component "path/to/myplugin.bundle" The bundle itself is build with XCode - it is a simple UI for user to type some input in Apple provides documentation for Distribution.xml file, which supports different UI elements but doesn't support text input - docs I have been also looking at this tutorial , it is very outdated but i could still fit it to my needs except the part where the .bundle file needs to be inserted into .pkg. Note - there is no option to view the contents of .pkg file build with pkbuild/productbuild How can i do this process correctly? I would like to link my installer pane plugin to a generic .pkg(with licenses and so on). I'd appreciate any kind of help!

Hi, Is there any way of changing the contentInset (UIKit variant) of a List in SwiftUI? I do not see any APIs for doing so, the closest I gotten is to use safeAreaInset . While visually that works the UX is broken as you can no longer "scroll" from the gap made by the .safeAreaInset(edge:alignment:spacing:content:) I have subbmited a feedback suggestion: FB16866956

I want to truncate text from head with max 2 lines. I try the following code import SwiftUI struct ContentView: View { @State var content: String = "Hello world! wef wefwwfe wfewe weweffwefwwfwe wfwe" var body: some View { VStack { Text(content) .lineLimit(nil) .truncationMode(.head) .frame(height: 50) Button { content += content } label: { Text("Double") } .buttonStyle(.borderedProminent) } .frame(width: 200, height: 1000) .padding() } } #Preview { ContentView() } It show result like this, this is not what I want.

Hi everyone! I'm thrilled to share that I'm conducting a field research as part of my final university project, focused on iOS architecture. The goal is to dive deeper into the best practices, challenges, and trends in the iOS development world. To make this research truly impactful, I need your help! If you're an iOS developer, I’d love it if you could take a few minutes to answer a short survey. Your insights and experiences will be invaluable for my research, and I greatly appreciate your support! Here is the link: https://docs.google.com/forms/d/e/1FAIpQLSdf9cacfA7my1hnlazyl7uJraa2oTsQ7dJBWvFtZ_4vbYenRA/viewform?usp=send_form Thank you so much in advance for helping me out—feel free to share this post with others who might also be interested. Let’s build something amazing together! 💡✨

I am working on creating a custom Popup View based on a .fullscreenCover. The .fullscreenCover is used to place the Popup content on screen on a semi-transparent background. While this works on iOS 18, there is a problem on iOS 17: When the Popup content contains a .sheet, the background is not transparent any more but opaque. Image: iOS 17. When showing the Popup an opaque background covers the main content. When tapping on the background it turns transparent. Image: iOS 18. Everything works as intended. When showing the Popup the main background is covered with a semi-transparent background. Removing the .sheet(...) from the Popup content solves the problem. It does not matter if the sheet is used or not. Adding it to the view code is enough to trigger the problem. Using a .sheet within a .fullscreenCover should not be a problem as far as I know. Is this a bug in iOS 17 or is there something wrong with my code? Code: struct SwiftUIView: View { @State var isPresented: Bool = false @State var sheetPresented: Bool = false var body: some View { ZStack { VStack { Color.red.frame(maxHeight: .infinity) Color.green.frame(maxHeight: .infinity) Color.yellow.frame(maxHeight: .infinity) Color.blue.frame(maxHeight: .infinity) } Button("Show") { isPresented = true } .padding() .background(.white) Popup(isPresented: $isPresented) { VStack { Button("Dismiss") { isPresented = false } } .frame(maxWidth: 300) .padding() .background( RoundedRectangle(cornerRadius: 20) .fill(.white) ) .sheet(isPresented: $sheetPresented) { Text("Hallo") } } } } } struct Popup<Content: View>: View { @Binding var isPresented: Bool let content: () -> Content init(isPresented: Binding<Bool>, @ViewBuilder _ content: @escaping () -> Content) { _isPresented = isPresented self.content = content } @State private var internalIsPresented: Bool = false @State private var isShowing: Bool = false let transitionDuration: TimeInterval = 0.5 var body: some View { ZStack { } .fullScreenCover(isPresented: $internalIsPresented) { VStack { content() } .frame(maxWidth: .infinity, maxHeight: .infinity) .background( Color.black.opacity(0.5) .opacity(isShowing ? 1 : 0) .animation(.easeOut(duration: transitionDuration), value: isShowing) .ignoresSafeArea() ) .presentationBackground(.clear) .onAppear { isShowing = true } .onDisappear { isShowing = false } } .onChange(of: isPresented) { _ in withoutAnimation { internalIsPresented = isPresented } } } } extension View { func withoutAnimation(action: @escaping () -> Void) { var transaction = Transaction() transaction.disablesAnimations = true withTransaction(transaction) { action() } } }
