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)

When I finished updating the system (Mac: 15.3.1 (24D70) Xcode: Version 16.2 (16C5032a)), the following situation occurred in the Archive package: Termination Description: DYLD, symbol '_objc_claimAutoreleasedReturnValue' not found, expected in '/usr/lib/libobjc.A.dylib', needed by '/private/var/containers/Bundle/Application/60C6E2BE-661A-4BA9-98CC-6C222F20452B/Blurams.app/Blurams' Highlighted by Thread: 0 A startup crash occurs on a system with iOS16 or earlier How to solve this problem?

I updated to iOS 18.4 beta developers and set the language of Siri and the phone to Spanish (Spain). Apple Intelligence says downloading but it never finishes. It has been connected to the wifi and plugged into the power for more than 12 hours.

Hello everyone, I'm looking for information on Apple's average response time for accessing the developer program. It seems to me that my application has been pending for approximately two weeks and I have not received any updates on the status of my process.

So I got charged the annual developer fee on December 2024, and then again this February 2025. Worse, a few days after getting charged twice, I received an email from Apple saying my developer account subscription has been suspended due to failure in paying the annual fee. I already submitted a support ticket to Apple, but I haven't gotten a response yet. Is there something else I can do? Would appreaciate any help. Thanks!

Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts

I have this code: var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16((EV_ADD | EV_ENABLE)), fflags: 0, data: 0, udata: nil ) I looked at it and thought why do I have those extra parentheses? So I changed it to var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16(EV_ADD | EV_ENABLE), // changed line! fflags: 0, data: 0, udata: nil ) and then kevent gave me EBADF. Does this make sense to anyone?

Why is it necessary that I have to reload all my personal apps developed by me for my use every year when I renew my Developer License? If I quit the program, anyone that bought my apps (if I had any) on the App Store would not lose the use of those apps. It should be the same for the apps I put on my devices when I am enrolled.

Dear Developers, I am having some problems with Reality Composer Pro on Mac. Specifically, I don't understand how to manage some timeline functions. I have an object that has a double animation, an opening animation and a closing animation. On a first tap the object should open through animation 1, while on the second tap the object should close through animation 2. Only the two animations conflict. In addition, animation 1 does not stop at the last frame but returns the object to the position of frame 0. Do you have any solutions? Thank you all

I developed my app on xcode, and it builds fine for xcode on simulator. However, when I transferred the swiftpm file to my ipad, the playground failed to build with only the error message "Build failed", while preview on playgrounds works fine. I am not sure what the cause of the error is, if anyone has any tips that would be greatly appreciated. Thank you.

Hello, There seems to be a regression with macOS SDK 15 and dynamically loading libraries if Address Sanitizer is turned on. Seems to only affect Debug builds, and .frameworks. I've also reported this via the Feedback Assistant: FB16513866 Here's a minimal repro, if anyone is interested: https://gist.github.com/peter-esik/6b00432e411be85333e14ae7d953966e I thought I'd post this here, as according to my web searches, this isn't a very well-known bug at this point.

Hello! We would like to know the steps required to build an application and submit it to the Apple Store using an automated process on a server. Here are our conditions: We have a server running macOS Sonoma 14.6.1 on Amazon EC2. Xcode 16.1 (Build version 16B40) is installed. We use only console commands, as the GUI is not available. We use Cordova to add the iOS platform to the application. A private key, certificate, and provisioning profile have already been created and are located on the server. Could you please clarify: What commands are needed to configure the Keychain to use the certificate and provisioning profile? How can we build the application using xcodebuild? What are the steps to sign and submit the application to the App Store with minimal human interaction? Thank you in advance for your assistance!

I’m experiencing a serious issue with my enrollment in the Apple Developer Program. I have been waiting for weeks with no response from Apple Support. Despite sending two emails (and now a 3rd) in an attempt to get a reply, I still haven’t heard back, even though I have completed all the necessary steps and received confirmation that my enrollment process has started. Has anyone else experienced a similar situation? If so, how did you manage to resolve it, or do you have any advice on how I can get Apple to respond and take action? I would really appreciate any insights or suggestions. Thank you in advance!

I used Swift Playground to develop application in Mac OS. Also using ZStack I used limited area in full page (using .frame(width: $, height: $)). However using command + R or clicking start button to see preview .app, while non resizing application my ZStack show as cutted. Please tell me how to set preview .app frame size as width, height... The buttom code is ContentView.swift code. @main struct ContentView: App { init() { MyFont.registerFonts() } // @StateObject private var audioPlayer = AudioPlayer() var body: some Scene { WindowGroup { NavigationStack { StartMenuView() .frame(minWidth: 594, maxWidth: 594, minHeight: 1142, maxHeight: 1142) .preferredColorScheme(.dark) // Dark Mod .statusBar(hidden: true) // Hidden Status Bar .edgesIgnoringSafeArea(.all) // Ignoring Safe Area } } .windowResizability(.contentSize) } } Thank you for reading. ![]("https://developer.apple.com/forums/content/attachment/8ad9f219-6caa-49bf-b8c3-e4b7c91ab40f" "title=image.png;width=1050;height=803") ![]("https://developer.apple.com/forums/content/attachment/395ee85e-9543-4bfd-9caf-3ce3c2ca8414" "title=image2.png;width=1104;height=973")

When I try to build my project in Xcode (from Unity AR) project, it throws me these errors: I feel like I've tried everything to make the LaunchScreen work. I downloaded xcode the night I tried running this build, so the whole deleting and redownloading and restarting everything didn't work. I've tried making sure my macbook and terminal are fully up to date. I literally can't find a solution! Please help!! I will also say, I'm fairly new to App building, Xcode, and Unity. But this does seem like a barrier that is stopping me from testing my project.

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.

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.

We applied for the Apple Developer Program more than two weeks ago, and our application is completely stuck with no updates or clear next steps. Despite providing all required documents (Company registration, D-U-N-S number, ID verification, etc. and several times !), we are still waiting for approval, while there is nothing complicated (EU citizens, UK company) We've reached out multiple times to Apple Support but have received no concrete answers or timeline for when our application will be reviewed. Meanwhile, we have successfully completed similar processes with Google, Meta, and financial institutions like banks or PSP, all within 48h ! How can a company like Apple treat its partners this way? The lack of transparency in the approval process is frustrating and severely impacts our timeline. This kind of experience does not inspire trust or confidence in doing business with Apple... 🔹 Has anyone else experienced such long delays in the enrollment process? 🔹 Is there any way to escalate this to get an actual response? Apple, please address this issue and provide a clear resolution. Thank you.

Hi! I wanted to use Lottie in my swiftpm app, but I've been running into errors and I'm not sure if it's possible. When I try to run the app, it crashes and I get errors saying that the library isn't loaded and the files aren't found (basically these: https://github.com/lottie-react-native/lottie-react-native/issues/373 , https://github.com/airbnb/lottie-ios/issues/2233 ). But moving the framework file into the PackageFrameworks folder doesn't work, and also I'm getting the error that swiftpm cannot distribute packages containing binary frameworks and from what I understand that just isn't something that swiftpm can do. So I was wondering if anyone knows any workarounds to this, or if I should just ditch Lottie? Any help or advice would be greatly appreciated!
