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, Im not sure why this happens.This is frustrating to see that despite paying the heavy amounts to join developer programme.The account is not getting confirmed surpassing way more than 48 hours of the payment. I paid the amount on 26th of December. and today is 29th. will you be compensating on the days we lost in this review process ?

I’m trying to integrate our app with the iXGuard obfuscation tool, which needs to run in the archive post-actions step in Xcode Cloud. The issue is: iXGuard takes a long time to complete and, during its execution, does not generate any console output or logs in the Archive Post-actions step. Problem: When Archive Post-actions runs for a long time without producing log output, Xcode Cloud triggers a timeout and the workflow stops before running the next CI step (e.g., ci_post_xcodebuild.sh). Even though the script continues running in the background, the workflow is aborted due to inactivity in the logs. Workaround Tried: As a workaround, I have ci_post_xcodebuild.sh print the logs generated by archive post-actions. However, this does not help in my case since the timeout occurs before ci_post_xcodebuild.sh even runs. Error: The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes. Question: Is there a recommended way to prevent Xcode Cloud from timing out during long-running steps that do not produce log output? Are there best practices for keeping the workflow alive with periodic logs during Archive Post-actions? Any support or workaround for integrating tools like iXGuard that require significant processing time after the archive step? Thanks in advance for your help!

I'm trying to download an iOS Simulator runtime in Xcode 26.2 or 26.1 on macOS 26.1, but the download keeps failing with the following error: Download failed. Domain: DVTDownloadableErrorDomain Code: 41 Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({ RequestedBuild = 23C54;}) Domain: DVTDownloadsUtilitiesErrorDomain. Code: -1. Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: {checkConfiguration = 1;} macOS & Xcode Info: macOS Version: 26.1 (Build 25B78) Xcode Version: 26.2 (24553) (Build 17C52) What I've tried so far: Formatted my Mac and reinstalled Xcode multiple times. Completely deleted Xcode and its related files several times (/Applications/Xcode.app, caches, preferences). Tried different internet connections from multiple locations. Checked Apple servers and verified network. Attempted downloading other simulator runtimes (fail). but download fails immediately with DVTDownloadableErrorDomain Code 41 and bad URL error. Question: How can I fix the simulator download issue in Xcode 26.2 on macOS 26.1? Is there a known workaround for the bad URL / catalog download error?

when i start to enroll apple developer account for organisation it could not be completed and in the end saying contact support. but when i mailed to them there is no support or reply from apple customer support. and there is no specification what problem i have from stopping me to complete apple developer account enrollement.

I am experiencing an issue where XCode reverts .xccurrentversion file in my iOS app to the first version whenever xcodebuild is run or whenever XCode is started. This means I can build the app and run tests in XCode if I discard the reversion .xccurrentversion on XCode start. However, testing on CI is impossible because the version the tests rely on are reverted whenever xcodebuild is run. The commands I run to reproduce the issue ❯ git status Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") ❯ git checkout "Path/.xccurrentversion" Updated 1 path from the index ❯ git status nothing to commit, working tree clean ❯ xcodebuild \ -scheme Scheme \ -configuration Configuration \ -sdk iphonesimulator \ -destination 'platform=iOS Simulator,name=iPhone 16 Pro,OS=latest' \ -skipPackagePluginValidation \ -skipMacroValidation \ test > /dev/null # test fails because model version is reverted ❯ git status HEAD detached at pull/249/merge Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") I have experienced such issue in 16.3 (16E140) and 16.2 (16C5032a). Similar issues/solutions I have found online are the following. But they are either not relevant or do not work in my case. https://stackoverflow.com/questions/17631587/xcode-modifies-current-coredata-model-version-at-every-launch https://github.com/CocoaPods/Xcodeproj/issues/81 Is anyone aware of any solution? Is there a recommended way I can run diagnostics on XCode and file a feedback?

I set "show live issues", but in the Xcode 26.2 version, I defined an unused variable in the function. This variable does not trigger real-time warnings; it only alerts when the compilation is completed. What settings should I make to trigger an alert for unused variables in real time?

Hi, I am running build on ios 26.2 device, connected with cable (not wifi) and it crashes because files are not loaded or something. But when i turn off Debug Exetuble, it works just fine. Also, tried to run on ios 18.2 device, with Debug executable On - everything is ok, and breakpoints work. My guess, App crashes on reading and loading Assets and others app files like certificates. XCode run logs shows: **"Too many file errors". ** sample.txt xcode_run_logs.txt Also, exectued image list on lldb console, could not attach here, if needed i can add it with some url here.

I’m encountering an issue on iOS when rendering a list using React. Each list item uses the array index as the React key and consists of two parts: a header section that uses position: sticky for dynamic sticking behavior, and a body section whose height is automatically adjusted based on its content. When the list data is updated, I sometimes observe that the sticky header content does not update visually in time, even though the underlying data and DOM have changed. // demo.jsx import React, { useState } from 'react'; import { Button } from '@iftide/mobile'; import './style2.less'; // import data1 from './data1.json'; // import data2 from './data2.json'; const prefixCls = 'im-detaillist'; const data1 = [ { sectionTitle: '2025年05月' }, { sectionTitle: '2025年04月' }, { sectionTitle: '2025年03月' } ]; const data2 = [ { sectionTitle: '2023年08月' }, { sectionTitle: '2023年07月' }, { sectionTitle: '2023年06月' }, { sectionTitle: '2023年05月' } ]; export default function App() { const [list, setList] = useState(data1); const [toggle, setToggle] = useState(true); return ( <div> <Button title="更新2" onClick={() => { setToggle(!toggle); setList(data2); }} /> <div className={`${prefixCls}-container2`} style={{ height: `700px` }}> {list.map((section: any, sectionIdx: number) => { return ( <div className={`${prefixCls}`} key={String(sectionIdx)} // id={section.sectionTitle} > <div className={`${prefixCls}-section-title`} role="text"> {section.sectionTitle} </div> <div style={{ background: 'green', height: `${Math.ceil(400 * Math.random()) + 50}px` }} > 省略 </div> </div> ); })} </div> </div> ); } .@{prefixCls}-section-title { position: sticky; position: -webkit-sticky; will-change: transform; top: 0; z-index: 1; padding-left: 11px; width: 100%; height: 30px; font-size: var(--font-size-s); font-weight: 400; line-height: 30px; color: #000000; background-color: #F4F5F7; letter-spacing: 0; }

Hi everyone, I’m experiencing a persistent issue when trying to download the iOS Simulator Runtime 26.1 on Xcode (version 26.1). The download always fails with the following error Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 I’m located in Brazil, so I initially thought it might be region-related, but I’ve already tried several attempts to fix it, including: Using VPNs for the US and Europe Installing the Xcode 26.2 beta Downgrading Xcode to earlier versions Reinstalling the same version of Xcode Restarting Xcode and my Mac Switching networks Clearing simulator support/device files Unfortunately, nothing has resolved the issue. Is anyone else facing this problem? Does anyone know a workaround or a manual way to download/install the iOS 26.1 simulator runtime? Thanks in advance!

After updated to Tahoe 26.2 and Xcode 26.2 it seems to have forgotten the Model Provider I had configured. I create a new Model Provider and it works fine, until I exit Xcode. When I open Xcode again my Model Provider is gone. It all worked fine before I did the updates of MacOS and Xcode.

My project requires the on-device apple intelligence models (FoundationModels) which are only available for iPad on iPad Pro M1 and later, iPad Air M1 and later, iPad mini A17 Pro. If they don't judge on one of these devices, my project might not work properly as FoundationModels is a pretty big part of my project. For this reason I really need to know what devices the Swift Student Challenge will be judged on.

Hello, I hope you are doing well. I recently submitted my app for review, and it was rejected. However, I am still unsure about the exact reason for this decision. I carefully reviewed the feedback provided, but some points remain unclear to me. Could you please clarify which specific guidelines were not met, or which parts of the app need to be changed or improved? My goal is to fully understand the issue so I can fix it properly and ensure that the app complies with all App Store Review Guidelines in the future. Thank you in advance for your time and support.

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

Hello guys, recently I integrated a third-party library into my code to handle blur effects (Glur). This library leverages Metal's compute capabilities and appears to automatically depend on the Metal toolchain during the build process. When using Xcode Cloud, the archive step consistently fails with a "CompileMetalFile Failed" error. However, when I manually archive the project in Xcode locally, everything works fine without any issues. I’ve confirmed that the macOS and Xcode versions specified in my Xcode Cloud workflow are correct. Reply if you know how to fix it or it will be fixed future, thanks. I'm using Xcode 26.2(17C52) and macOS(15.7.1 (24G231))

I have an open NFC Value-Added Services entitlement case (17370116) with Apple Wallet Entitlements. My request was acknowledged, information provided, but the case appears to have been split into duplicates and stalled. Is there a way to have the case consolidated and routed back to the Wallet Entitlements team?

Since Dec 18th, my Xcode Cloud builds (for multiple apps) have been failing with this error: Command line name "app-store" is deprecated. Use "app-store-connect" instead. I haven't made any changes to my system, signing, etc, and two separate apps started failing at the same time. No matter what I change on my Workflows (environment, new workflow from scratch, etc), nothing seems to fix it, which leads me to believe this is a bug with Xcode Cloud itself. I've logged FB21456291 already, but just wanted to post here to see if I'm missing something.

Several lessons in Keep Going with Apps cannot be completed even when the code is correct. This blocks progression and greys out the Next button permanently.

I have opened a case with the apple developer support a month ago and they have not replied, since then I sent multiple other emails and opened more cases requesting them to get a status update about my case. So far I am being ignored, no reply or anything it is very frustrating, what can I do to get someone to help me with the apple developer team?

Hi, Some time ago I created an Apple Developer business account on behalf of my (now former) business partner. The company is no longer active, and I've been away from app development for a few years. I'd now like to start fresh with a new business account, but first I need to step away from this existing one. From the documentation, I understand that first I have to transfer the Account Holder role, and I've already spoken with the other person - he's willing to accept the role. According to the docs: https://developer.apple.com/help/account/access/transfer-the-account-holder-role/ the option should appear under "Update your information", but in my case there is no option called "Transfer Account Holder role". Has anyone encountered this before? Are there prerequisites or account conditions that need to be met for the transfer option to appear? Thanks in advance for any guidance.
