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’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?

I'm receiving this error when attempting to log into my game and authenticating via Firebase and Game Center. I am using Unity to develop my game and have been able to successfully authenticate with Google Play and Apple Sign In but Game Center is giving some trouble. The error seems easy enough except I have triple checked that I am signed in to Game Center with the profile that is set up in Sandbox Testing. Other things I have verified: I have a provisioning profile and game center is on it. In xCode I have Game Center on my signing capabilities, entitlements, and have the GameKit.framework in my Link Binary with Libraries. Any ideas as to what may be causing this error to throw? Maybe another step I missed somewhere?

Dear Apple Support Team, I am Tianwei Yue. I received your email this morning regarding the immediate termination of our Apple Developer Program License Agreement and Apple Developer Agreement, citing alleged fraudulent behavior and violations of certain terms. We are both surprised and deeply anxious about this decision. Firstly, the email mentioned that if we wish to file an official complaint under the applicable Platform Regulation, we could contact you via “Contact Us”. However, when I logged in with my account and clicked the “Contact Us” link, the system responded with “You’re not eligible to make this request.” We would appreciate guidance on how to properly submit an official complaint or if there is an alternative way to reach out for assistance. Secondly, I would like to emphasize that the “mathos ai” application operated under this account currently has over 3 million active users. Our application has consistently maintained a high user rating of 4.6 and a record of excellent service. The immediate deletion of our account has rendered the service inaccessible to a large number of customers who use Apple products, severely impacting their experience. We believe that this decision does not align with the shared values of customer care that both Apple and we have always upheld. We have always been proactive in handling user accounts, refunds, and payment issues, and we continuously strive to provide high-quality service to our users. Consequently, we are puzzled by the reason for the account suspension and believe that there might be some misunderstanding or miscommunication. We sincerely hope to connect with the relevant Apple personnel to understand the issue in detail and provide any necessary additional information to resolve any concerns and restore our service. Thank you very much for taking the time to read our email. We look forward to your prompt response so that we can resolve this issue and jointly safeguard the interests of our valued customers. Sincerely, Tianwei Yue

I am creating an imessage sticker pack and I am having an issue with an update of my app. It publishes to test flight but I can't download it to test. My app has an extension of imessage. I have tried: Checking the size of the animated stickers. All are below 500kb My version number is 4.1.1. so no 0 I am really no sure what to do. Any suggestions would be appreciated.

Hello all! My application written with C++/CMake and when building have some troubles with adding test environment for StoreKit every time - it need to be done manually. Is there any way to add StoreKit environment settings with CMake and when executed command like this $ cmake -g Xcode ... StoreKit test environment were automatically added?

I can sucessfully send pushes to an app (which has been installed/run via Xcode) when the pushes are going through the Apple sandbox server. However I want to test the server is configured correctly to send them through the Apple production server. In the Xcode scheme I tried to change the build configuration to release (and ticked debug executable off) ,however the pushes still only work when sent through the sandbox. Is there a way of installing/running the app using Xcode such that its compatible with the push production environment? Does the APS Environment entitlement come into play here? this only ever says development. (The app is on behalf of a 3rd party company, they've added me to their apple developer account but with limited powers, I can't upload to Testflight nor make an ad-hoc release with with to test with)

Hello, In 2024 I received notice of Apple Developer Account termination (Team ID: FCKZLDS8EQ) (with no reason) and in 5 days I have sended the appeal. After 30+ days - my account was terminated. The notification said that I only have a month to file an appeal, I did it within 5 days, but neither during the month nor so far - I have not received a response. Also, after the appeal, I contacted support saying that there was no response to the appeal and still remained unanswered to these tickets: 102346160903 and 102349953096. I described everything in detail in that appeal. I have an Apple Developer membership since 2014 and this is some kind of misunderstanding, I have an old trusted developer account without any violations.

After updating from Xcode 15.4 to Xcode 16.2, I am unable to build my project. I would greatly appreciate any advice or guidance on how to resolve this issue. Thank you in advance for your help and guidance.

I get this error: Verification failed with status INVALID_APP_IDENTIFIER we use this method: payload = signed_data_verifier.verify_and_decode_notification(notification_data) I use Production environment (this is automatically set in our server) and use my device (connected to Mac) to test the purchase. When trying to purchase I get the Sandbox environment in the Widget. This works when manually setting the environment to Sandbox before calling the function. The time it works because it does not check the apple app id (because of the environment). Now my question is: Which is the apple app id? Is it the App Id "Apple-ID" in the app store connect? Or is it the TeamId+BundleId? Could it be that my function doesnt work because the Payment was done in Sandbox and the environment is Production?

I'm having trouble compiling my project for the iOS 18.2 simulator. I'm getting the following error: `Missing '#include <sys/_types/_time_t.h>'; 'time_t' must be declared before it is used` The error points to to simulartor-iOS 18.2 > user/include/sys/_types/_time_t.h #ifndef _TIME_T #define _TIME_T #include <machine/types.h> /* __darwin_time_t */ typedef __darwin_time_t time_t; #endif /* _TIME_T */ This suggests that the time_t type should be defined, but the compiler isn't seeing it. I suspect there might be a problem with preprocessor definitions. Is there anything I set wrong? I am using OpenSSL.xcframework.

Is there anyone here who can provide an answer, or is it related to someone who belongs to the App Review department at Apple? We uploaded an app to the App Store and discovered a bug that disables activity. We uploaded an update with the bug fix and now we are waiting for Apple to review the latest version and approve uploading it to the store. Thousands of users are waiting and leaving us. Losses of a lot of money and more importantly - a bad user experience. If there is anyone here who can help us, or knows someone who can speed up the process, we are more than happy!!! It is critical and urgent. And yes, we signed up for Apple's fast track program... It didn't help. Thanks!

I enrolled to the apple developer account more than one week ago. Nothing! After 3 or 4 emails to support I received an email with steps I should perform from the iPhone app. I did so, my money was charged and ... nothing. My enrollment has been withdrawn no activation nothing. I made another request (although I am not sure that it is ok). Can somebody help me?

I just made clean data on simulator then started getting the below error built on Xcode ? Showing Recent Issues Entitlements file "Clinic.entitlements" was modified during the build, which is not supported. You can disable this error by setting 'CODE_SIGN_ALLOW_ENTITLEMENTS_MODIFICATION' to 'YES', however this may cause the built product's code signature or provisioning profile to contain incorrect entitlements.

I checked privacy & security tab in settings but I dont see developer mode anywhere.

I'm trying to build an app for Mac from an external source and the build process fails due to the requirement of a provisioning profile. I'm new to developing in Xcode and as far as I've know rn, you need to have a developer account to create a profile. I just want to test the app locally. Not sure if a profile is required for that.

I am Developer of SMCB ANAND Application, my Apple Developer Program membership had been expired in September 2024. I observed that expired in November 2024. Since that time i couldn't able to renew Apple Developer Program membership. I went through Apple Developer app for renew the membership but still i couldn't renew it Kindly provide a solution for the same

When Xcode 16.2 connects iPad to real machine debugging using the view in the picture box, the mac will be stuck directly, the computer cursor will disappear, and the computer cannot do any operation

I find Xcode's Debugging Variable View to be to cluttered, even when just watching "local" variables. Is there anyway to set it so that it only shows the variables I want to watch? Would make debugging so much easier.
