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 Developer Tools. Will my project codebase be used for training when I use Xcode's intelligent assistant powered by cloud-based models? When using ChatGPT without logging in, your data will not be used to improve any models. If you log in to a ChatGPT account, this is based on your ChatGPT account settings, which allows you to opt-out (it defaults to on). When using Xcode with accounts for other model providers, you should check with the policies of your provider. And finally, at no point will any portion of your codebase be used to train or improve any Apple models. We'd love to make our SwiftUI Previews (and soon, Playgrounds) as snappy as possible. Is there any way to skip certain build steps, such as running linters? It seems the build environment is exactly the same (compared to a debug build), but maybe there's a trick. Starting with Xcode 16, SwiftUI previews use the exact same build artifacts as the regular build. The new Playgrounds support in Xcode 26 uses these build artifacts too. Shell script build phases are the most common thing that introduces extra build time, so as a first step, try turning off all shell script build phases (like linters) to get an idea if that’s the issue. If those build phases add significant time to your build, consider moving some of those phases into asynchronous steps, such as running linters before committing instead of on every build. If you do need a shell script build phase to run during your build, make sure to explicitly define the input and output files, as that is a huge way to improve your build performance. Are we able to provide additional context for the models, like coding standards? Documentation for third party dependencies? Documentation on your own codebase that explains things like architecture and more? In general, Xcode will automatically search for the right context based on the question and the evolving answer, as the model can interact multiple times with your project as it develops an answer. This will automatically pick up the coding style of the code it sees, and can include files that contain architecture comments, etc. Beyond automatic context, you can manually attach other documents, even if they aren't in your project. For example, you could make a file with rules and ideas and attach it, and it will influence the response. We are very aware of other kinds of automatic context like rule files, etc, though Xcode does not support these at this time. Once ChatGPT is enabled for Coding Intelligence in Xcode 26, and I sign into my existing ChatGPT account, will the ChatGPT Coding Intelligence model in Xcode know about chat conversations on Xcode development done previously in the ChatGPT Mac app? Xcode does not use information from other conversations, and conversations started in Xcode are not accessible in the web UI or ChatGPT app. Is there a plan to make SwiftUI views easier to locate and understand in the view hierarchy like UIKit views? SwiftUI uses a declarative paradigm to define your user interface. That allows you to specify what you want, with the system translating that into an efficient representation at runtime. Unlike traditional AppKit and UIKit, seeing the runtime representation of SwiftUI views isn't sufficient in order to understand why it's not doing what you want. This year, we introduced a SwiftUI Instrument that shows why things are happening, like view re-rendering. Is it possible to use the AI chat with ChatGPT Enterprise? My company doesn't allow us to use the general ChatGPT, only the enterprise version they have setup that prevents data from being leaked Yes, Xcode 26 supports logging into any existing ChatGPT account, including enterprise accounts. If that does not meet your needs, you can also setup a local server that implements the popular chat completions REST API to talk to your enterprise account how you need. Now that Icon Composer is here, how does it complement or replace existing vector design tools such as Sketch for icon design? Icon Composer complements your existing vector design tools. You should continue to create your shapes, gradients, and layers in another tool like Sketch, and compose the exported SVG layers in Icon Composer. Once you bring your layers into Icon Composer, you can then use it to influence the translucency, blur, and specular highlights for your icon. What’s one feature or improvement in the new Xcode that you personally think developers will love, but might not immediately discover? Maybe something tucked away or quietly powerful that’s flown under the radar so far? One feature we're particularly excited about is the new power profiler for iOS, which gives you further insights into the energy consumption of your app beyond what was possible with the energy instrument previously. You can learn more about how to use this instrument and how it can help you greatly reduce your apps battery usage in the documentation, as well as the session Profile and optimize power usage in your app. There were also improvements in accessibility this year with Voice Control, where you can naturally speak your Swift code to Xcode, and it understands the Swift syntax as you speak. To see it in action, take a look at the demonstration in What’s new in Xcode 26. We have a software advisory council that is very sensitive to having our private information going to the cloud in any form. What information do you have to help me guide Xcode and Apple Intelligence through the acceptance process? One thing you can do is configure a proxy for your enterprise that implementing the popular Chat Completions API endpoint protocol. When using a model provider via URL, you can use your proxy endpoint to inspect the network traffic for anything that you do not want sent outside of your enterprise, and then forward the traffic through the proxy to your chosen model provider. Are there list of recommended LLMs to use with Xcode via Intelligence/Local? I've tried Gemma3-12B, but.. I hope there are better options? Apple doesn't have a published list of recommended local models. This is a fast-moving space, and so a recommendation would become out of date very quickly as new models are released. We encourage you to try out the local model support in Xcode 26 with models that you find meet your needs, and let us and the community know! (continued below)

I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle. This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs. When it's selected, it looks right and the layers move correctly: But when it's not selected, the background layer disappears: Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why. I've spent a day trying everything. Very frustrated. The icon previews correctly in Xcode and in Parallax Viewer. The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large. The back layer is a non-transparent PNG. I tried adding a Large@2x set. Didn't help. Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help. All the PNG files are from GnuIMP. Same color space, even. I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.) Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.

Hi guys, I have set size of cube is 20 cm. Then i want to transform scale with values x: 0.048, y: 1, z: 0.0.48, But strangely it reset all value to x: 1, y: 1, and z:1. Then i want to try with another decimal such as x: 1.2, y: 2, z: 1.2 the panel will automatically reset it into x: 1, y: 1, z: 1. My question is how to set transform scale that can accept decimal number ?

It only seems to happen in the real app I am working on and not within any of the test apps I make. Its lasted a few Xcode versions. Don't know if this is widespread to the point of having a name?

Today I got stuck with a weird behaviour with my c++ project. There is the code which doesn't catch exception from standard library (the same snippet works well on intel mac and under linux machines). Code snippet: #include <exception> #include <stdexcept> #include <iostream> #include <string> int main() { try { std::stod("notanumber"); } catch (const std::invalid_argument&) { std::cerr << "Caught std::invalid_argument" << std::endl; } } Compilation command: clang++ -fno-rtti main.cpp -o main && ./main Clang versions: clang++ --version Homebrew clang version 15.0.3 Target: arm64-apple-darwin21.6.0 Thread model: posix InstalledDir: /opt/homebrew/opt/llvm/bin Also tried: Apple clang version 14.0.0 (clang-1400.0.29.102) Target: arm64-apple-darwin21.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin Output: libc++abi: terminating with uncaught exception of type std::invalid_argument: stod: no conversion [1] 65643 abort ./main Expected output: Caught std::invalid_argument Other info: Chip: Apple M1 OS: 12.6

Is remotepairingd part of Xcode? It seems to be stuck using 119% CPU. This may have started when I recently paired my new Apple Watch with Xcode - or maybe that is a coincidence. The console is full of: error 16:40:26.237601+0000 remotepairingd socket-1: No more data can be received, connection was closed

I followed this guide, and added com.apple.developer.spatial-audio.profile-access as an entitlement to the app (via the + Capability button – Spatial Audio Profile). I have a audio graph that outputs to AVAudioEngine. However, the Xcode Cloud build ended up with this error: Invalid Code Signing Entitlements. Your application bundle's signature contains code signing entitlements that are not supported on iOS. Specifically, key 'com.apple.developer.spatial-audio.profile-access' in 'Payload/…' is not supported. This guide says it's available on iOS. Does it mean not on iOS 17? In which case how can I provide fallback for iOS 17?

I saw in the Xcode 16 release notes that on-device debugging is no longer available on watchOS prior to version 7.0, but I can't even get a signed, compiled app to run on an older watch. The current version I have live in the App Store works just fine on 4.3.2. I have changed no code, I just started building the app with Xcode 16, and now it won't launch on older watches. Is it no longer possible to update an app for older watches?

I've got an existing app which is using some 3rd party xcframeworks within its app extensions (for example within a Notification Service Extension). Within the target for the app extensions there is a Frameworks and Libraries section where the xcframework was dragged and dropped into. However now I want to create a new project and do a similar thing, within the app's target there is a Frameworks and Libraries section, but when an app extension target is created, Xcode is not adding a Frameworks and Libraries section. There is a Link Library with Binary section, however this doesn't have an embed section (where you can select to embed, don't embed, embed without signing etc.) and I get build error trying to drag and drop the xcframework in here. Where id the Framewoks and Libraries section go for app extensions for projects created with Xcode 16? How can this section be added?

For normal testing I build an application using Xcode and selecting "Build for Profiling" from the Product menu. For production I do "xcodebuild clean build -configuration Release ......." I notice a big performance difference. In my case the XCode profiling build runs in under a minute, the xcodebuild version takes over 4 minutes. The XCode profiling build uses the Release configuration, the xcodebuild is also using the Release configuration. What additional configuration options are being set/used when "Building for Profiling"? I'm having a hard time finding an answer to this question.

I have developed a mobile app using SwiftUI. Now I am in the process of building a CarPlay application. I know how to test the CarPlay app using a simulator but here is my confusion, Testing the iPhone app and CarPlay together (few scenarios like user login / logout, location enabled /disabled in the mobile app) Kindly help me validate the above scenarios as I am getting black screen on iPhone whenever the CarPlay is launched. Below is the code snippet, func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration { if connectingSceneSession.role == .carTemplateApplication { let sceneConfiguration = UISceneConfiguration(name: "CarPlay Scene", sessionRole: connectingSceneSession.role) sceneConfiguration.delegateClass = CarPlaySceneDelegate.self return sceneConfiguration } // Configuration for other types of scenes return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role) } struct MyApp: App { @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate var body: some Scene { WindowGroup { ContentView() .preferredColorScheme(.light) } } } Info.plist <key>UIApplicationSceneManifest</key> <dict> <key>UIApplicationSupportsMultipleScenes</key> <true/> <key>UISceneConfigurations</key> <dict> <key>CPTemplateApplicationSceneSessionRoleApplication</key> <array> <dict> <key>UISceneConfigurationName</key> <string>CarPlay Scene</string> <key>UISceneDelegateClassName</key> <string>$(PRODUCT_MODULE_NAME).CarPlaySceneDelegate</string> </dict> </array> </dict> </dict>

Am running Xcode 16.1 on Sequoia and am getting "No such module" error. Here are my steps: Create workspace in Xcode and name it AccessControl2 Create Project named OrangeInc and add it to AccessControl2 group. Create blank playground named AccessControl and add it to AccessControl2 group Error message in playground after I add "import OrangeInc" reads "No such module" Have tried repeating this several times; get same error message.

What is the reason for the input box on the login page of the self-developed APP not working in the new version of iOS?

After upgrading to XCode 16.2, I am not able to see apple watch in xcode. I was able to see in XCode 15.2.

Device : macOS Monterey 12.7.6，Xcode 14.2，IOS 16.0.2; I tried adding -ld_classic or -ld64 to the other link flags，but it did not work for me。 How should I fix this?

Hello, I am doing the SwiftUI tutorial with Xcode 16.2 For the watch app the simulator working fine but the preview keep saying “This app cannot run on the selected target device.” while the preview is working …… For the macOS part the simulator working fine but the preview is totally broken with -> ”ContentView.swift” not found in any targets. While it is correctly added to the target … Please fix or make tutorial clear.

After updating Xcode my app stoped running on real device

Please see this question: https://github.com/appium/appium/discussions/20827?sort=new

Our team is currently handling hang issues and logs received by the Organizer during our project. Regarding the xCode Organizer, we’d like to ask a few questions: The hang rate is presented as a bar chart for each app version. Is there any way to get detailed information for each versions? For example, what percentage of the hang rate is attributed to users on different iOS versions? We've encountered a situation where the hang logs have decreased, but the hang rate has increased. Could you explain why this might occur? I was wondering how the hang rate is sampled. For instance, does it record all users who experience a hang, or only those under specific conditions? The situation is that we can see only a handful of hang logs (around 13), but we have hundreds of thousands of DAUs. This ratio seems quite off. Could you explain what might cause us to receive such a small number of logs for each version?

When I try to open Xcode, it tries to open the previous windows and load up the project I was last working on, but I can’t create a new project without opening Xcode, and I can’t do that; it just quits and gives me an Xcode quit unexpectedly, and it still happens when I download earlier versions of Xcode from the Apple developer website and the latest from the App Store, and I even when in Finder and tried to open my project that way, and it just does the same thing. I have tried everything, and I mean everything. I even reinstalled macOS, and it worked for a minute until it tried to open my project and then quit again and is doing the same thing.

Let's say I have a local package Foo, Bar and Baz. Foo has Bar and Baz as dependency and has test target,FooTests. Below is the Package.swift manifest that describes package Foo. import PackageDescription let packages: [Package.Dependency] = [ .package(path: "../Bar"), .package(path: "../Baz"), ] let products: [Target.Dependency] = [ .product(name: "Bar", package: "Bar"), .product(name: "Baz", package: "Baz"), ] let package = Package( name: "Foo", platforms: [ .iOS(.v16), ], products: [ .library( name: "Foo", targets: ["Foo"] ), ], dependencies: packages, targets: [ .target( name: "Foo", dependencies: products, path: "Sources" ), .testTarget( name: "FooTests", dependencies: [.target(name: "Foo")], path: "Tests", swiftSettings: swiftSettings ), ] ) Bar and Baz is also local packages. Due to the limitations of the project, Baz has sources with symbolic links instead of exact directories, and these sources are what FooTests will test. If I run FooTests, test succeed with proper logs indicating that all test methods are run correctly, but test coverage says that Baz's coverage is 0% and there is no executable lines unlike the Bar which is not what be tested. Is there any way to fix this problem?
