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)

Hello, My payment system works correctly when my backend is in sandbox mode, but when I submit my app for review, I get the following error: VerificationException [Error] at SignedDataVerifier.verifyNotification (/Users/---/node_modules/@apple/app-store-server-library/dist/jws_verification.js:126:19) at SignedDataVerifier.verifyAndDecodeNotification (/Users/---/node_modules/@apple/app-store-server-library/dist/jws_verification.js:121:14) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async file:///Users/---/src/api/routes/apple.routes.js:22:18 { status: 2, cause: undefined } Main Question For Apple to approve in-app purchases, should I submit my app for review with the backend in sandbox mode or production?

Update Xcode 16.2 but i get error Assets Validation Failed upload to Appstore,

Hi! I have now spend a few days of trying to only get the option in Xcode to distribute to App Store. My app works on my own device, I have paid developer account and created a record for the app and its bundle id in App Store Connect. After archive the only options I can see is "Release testing, Enterprise, Debug and Custom". I have verified a lot of settings in both info.plist and build settings, without luck. I also see that the "Validate" button is greyed out, and the "SKIP_INSTALL" does not do the trick to enable it, and the archive is not a generic one, its explicit for watchOS. Using Xcode 16.2. Any suggestions of what to try before registering a support case.

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

Hello, Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices. Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations? TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.

We are encountering a persistent code signing error with in-app purchase capabilities in our iOS app. Despite having the com.apple.developer.in-app-purchase entitlement properly configured in the app's entitlements file and the In-App Purchase capability enabled in both Xcode and the App ID configuration in the Apple Developer Portal, we continue to receive the error: "The provisioning profile 'iOS Team Provisioning Profile: does not include the com.apple.developer.in-app-purchase entitlement." We have attempted multiple solutions including: Regenerating provisioning profiles Cleaning and rebuilding the project Switching between automatic and manual signing Removing and re-adding the in-app purchase capability Verifying all entitlements and capabilities configurations The error persists despite the entitlement being correctly set in the entitlements file and the capability being enabled in the App ID. This appears to be an issue with how the provisioning profile is being generated or how the entitlement is being recognized by Xcode's code signing system.

Hey, I wanted to create a Mac-OS application. Normally I only code iPhone apps. But as soon as I want to display anything on the preview, it loads, just as normal, and then the throbber/progress indicator disappears and the preview canvas stays gray like it used to be before. I also don't get any error messages. Only one time after trying different things I got one message saying: "Could not launch Preview Shell." and "Could not create FBSOpenApplicationService." I also searched for a few solutions and tried some but none of them seemed to work. In the DiagnosticReports were some files of the time but I didn't seem to find anything helpful in there and they don't appear when I reopen my project or switch from PreviewMode "My Mac" to "iPhone 16 Pro". When I launch the app on a simulator it works perfectly fine but this is quite annoying. Thanks for trying to help me!

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.

Hello, I used to add openssl static libraries (libssl.a, libcrypto.a) that, I created on Mac, and add them after to my C++ project within XCode. With Xcode 14.2 (and before) all works fine. Switching to Xcode 15.2, tons of link errors rise (ld: Undefined symbols). I tried _ld_classic to force use 'old' linker but no success. Rebuild the static libraries with multiple config param or upgrade to recent openssl library does not help. Any clues what went wrong when linking static libraries with Xcode 15.2 project? Thx.

I am trying to update my AboutView.xib file (https://git.callpipe.com/AccelerateNetworks/an-mobile-ios/-/blob/main/Classes/Base.lproj/AboutView.xib) through the xcode interface builder, and the changes that I make are correctly reflected in the wysiwyg, as well as in the file itself. However, I whenever the app is built and installed, it shows an older version of the about page. Things I have tried to resolve this are (not listed in order): Product > Clean Build Folder Uninstall and reinstall the app Restart the phone Restart xcode Restart the computer Test a build created through xcode cloud rm -rv ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Caches/com.apple.dt.Xcode rm -rf "$(getconf DARWIN_USER_CACHE_DIR)/org.llvm.clang/ModuleCache" Changing something in the xib file (hoping it will recognize a change) The only time the about page has shown something different is when I deleted the xib entirely. The project still built and deployed to the test device, but the about page was completely blank. This tells me I am working with the correct file, and when I look at the xml contents of the file, I can't find any of the old strings that are showing up. What the editor shows: What the app shows:

How to collaborate project between Unity Dev and Xcode SwiftUI Dev, is it possible..? and how is the workflow for that if possible..?

In my Swift app, Xcode has decided to put various important settings like, SWIFT_VERSION under "User Defined." Does anyone know why?

I'm trying to add an iMessage extension to my app, and upon adding the iMessage App Icon set, I ran into an issue with one specific icon size: 1024x768px, aka 1x 1024x768pt. When I remove this one icon from the icon set, it compiles and runs fine, however I can't push it to the App Store as I get the error: "Asset validation failed. Missing Image Asset. Your app is missing the Large App Icon asset 'AppIcon' in 'Payload/Runner.app/PlugIns/MessagesExtension.appex'." I'm assuming this refers to 1024x768px, as this size placeholder appears upon adding a New Messages Extension Icon to my assets folder, and 1024x1024 is already included and compiles fine with it. However, when I add the 1024x768 icon, and try to run the app, I get the error: "Command CompileAssetCatalog failed with a nonzero exit code" The app icon's filename is correct, it is exactly 1024x768 px, and my contents.json correctly includes : { "filename" : "AppIcon_1024x768.png", "idiom" : "ios-marketing", "platform" : "ios", "scale" : "1x", "size" : "1024x768" } as is the same format for all of my other icons that work. Why am I running into this issue upon inclusion of this one required size? How do I fix it?

I am currently using Xcode 16 (16A242d) and testing on an iPhone 7 running iOS 12.1.3. However, when I try to launch the app on the device, it crashes immediately.

I would like to know the possible reasons for this behavior.

When renaming a variable in the active scheme, it's not renamed for the non active ones. As a result when you have code that operates in both schemes (with #if os() conditions) a compile time error is introduced. Is this an Xcode bug or expected behaviour?

I’m working in the app playground and want to add my usdz file but when i drag drop the file to my main folder i cannot add target to it which leads to a resource not found error while I build my app. It was working on a normal xcode project but while transitioning to app playground it is not working. How can I fix this issue?

A while ago, perhaps early in v16, Xcode stopped tracking file liveness. I'd hoped the regression would be fixed, but... not yet. Is there some setting I'm missing? Is this from underlying filesystem limits? or from working with swift packages? Conversely, if/since this is a regression, is this the new normal, and not to be fixed (e.g., because the modern build system cannot be retrofitted to detect and update stale resources)? Assuming I create a Swift package and open it in Xcode... 1. New files I expect to get errors when I create a new swift file, add bad code, and build. Instead, the file doesn't seem to be added to the build. If I try to use Add Files to "{project}".. menu, the file is disabled for selection. A workaround is to close and re-open the project 2. Files updated extrinsically If outside Xcode I format the files in the package or edit them, I expect Xcode to notice and either 1) update with the new contents if there were no changes, or 2) ask what to do if there were changes. Instead, Xcode proceeds oblivious to the underlying changes. It is not a workaround to use Integrate/Refresh file status menu for SCM status. Again, a workaround is to close and re-open the project. Possible factors Swift package projects, if resource tracking is tied to metadata unused in package projects? External filesystem: these are on APFS volumes mounted via TB-4 and USB-3 Pilot error? Impact This leads me to re-open projects 10's of times a day, to create test files or maintain lint. Also, because I have to drop out of Xcode to process files before checking in, I end up using an external git workflow/UI. Also, because Xcode is not particularly extensible, I've written external tools for analyzing and generating Swift, hosted via CLI or eclipse (which support resource markers for UI navigation). I use Swift LSP in Eclipse for analysis and git-driven changes, and end up coding there because well, I'm already there. I'd take slower builds over this continuous hassle and context-switching in a heartbeat.

Hi everyone, I’ve been experiencing a persistent issue with my MacBook Pro (M2 Pro, macOS 15.2) when using Xcode (version 16.2). If Xcode is open and my Mac goes into sleep mode, the screen size changes upon waking. Specifically, I notice 3mm bezels appear on each side of the screen, making the display slightly smaller, and everything scales down to fit this reduced size. This issue happens multiple times a day and has been ongoing for over a year. It’s quite disruptive to my workflow. Here is a video to illustrate the problem: Has anyone encountered this before? If so, do you have any suggestions for fixing it or steps I can take to debug the issue? Thanks in advance for your help and support!
