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, I recently updated my app, and in the Transporter app it said that the processing failed. This is the email I recieved: Please correct the following issues and upload a new binary to App Store Connect. ITMS-90048: This bundle is invalid - Your archive contains paths that are not allowed: [._Symbols] I couldn't find anything related to this in XCode or anywhere else on the internet. What did I do wrong? For context, I am developing using Expo and React Native.

I'm trying to evaluate if we can support AR navigation with MapKit. The feature is supposed to be available for users in US. I tried to run the sample on my iPhone: https://developer.apple.com/documentation/arkit/tracking-geographic-locations-in-ar?language=objc But I'm in a location that ARGeoTrackingConfiguration.checkAvailabilityWithCompletionHandler: always return false. I think ARGeoAnchor isn't supported in my location. I tried to use simulated locations by Adding a gpx file when launching the app. Enabling Xcode -> Debug -> Simulate Location -> New York, NY, US But the availability for ARGeoAnchor is still false. Is that possible for me to develop the ARGeoAnchor feature outside of the covered areas?

Hello, We are struggling with a case creating the accounts for a company from Serbia and Croatia. The specific issue we are facing with these two accounts is that the enrollment is accepted without any problems. However, it is worth noting that during the registration of the Serbian account, Apple requested personal documentation from the account holder. Once the documentation was provided, the enrollment was successfully completed. However, when it comes to making the subscription payment, the transaction does not process correctly. We have tried making the payment from different devices and using various payment methods, but in all cases, we have been unable to activate the account. We always consider Apple's 48-hour processing time for payments, but after that period, we receive no information—neither account activation nor payment rejection. When we contacted Apple Support to explain our case, the only solution they provided was to cancel the Apple Developer enrollment and start the entire process again. However, even after doing this, the client is still unable to activate their account. Hope that someone that faced the same issue can help with this as Apple support won't give us more information about which can be the problem. Thank you,

I want use Swift and objective-c both, I build bridge header ,but I got to errors. I can't fix them. Please help me. Thank you . ios iphone app.

I am working on an XCode project and I have some Swift functions within a helper functions file. This file has some functions declared that create 3 global variables. These global variables are then used in various views throughout the app. In the functions, there are print statements for when it catches an error. However, when I run the app and I get an error that stems from this file, there are no print statements. How can I have this print statements show up in the debug console?

Hi, I have an app where user can select an amount within range 20$ - 2500$ and purchase tokens worth that amount, so if he pays 520$ he gets 520 tokens. They can then use these tokens to unlock content within the app. As far as I've seen, in-app purchase doesn't allow custom price set by user. So does this mean we can use third-party payment services? If no, how can we achieve this using in-app purchase. Thank you.

My clients are waiting.. i had to give them some excuses and discounts... everything is ready from my side but the enrollment is delayed already more than 1 month. The support did replay after 1 week , all they did was to withdraw my enrollment and tell me to try again , and back to point zero... and I'm waiting... I did try to open two accounts , one personal and one for organization so i can at least give my clients their app. now I'm checking both accounts daily basis . oh you may wounder what happened with support ? they did answer fallow my case a little but didn't provide a solution , and then stopped responding... I'm losing money, time and hope to this system.

I've got an app where I want to split its Model code into a framework (.xcframework and .framework for debugging) so that it can be used by more than one app. The code has dependencies on 3rd party code, which are installed via pods. During the conversion process I keep running into the same issue which manifests with all the 3rd party code - which is that the majority of its api can be used (something like 80-90%) but for the remainder there is a linker error at runtime showing undefined symbols. I have this problem with CocoaLumberjack,RealmSwift, PhoneNumberKit and more. Its very quick and easy to reproduce the issue with a minimal framework and minimal app, below I'll describe how a minimal setup using CocoaLumberjack reproduces the issue: From scratch, I use Xcode to create a framework project, run pod init, then modify the pod file to be: platform :ios, '16.0' workspace 'TheFramework' project 'TheFramework' target 'TheFramework' do use_frameworks! pod 'CocoaLumberjack/Swift', '3.8.5' end post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0' config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES' end end end Then I add source code: import Foundation import CocoaLumberjack public class AClassInTheFramework { public class func aMethod() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) DDLogDebug("Some logging") } } Within the Xcode project, Build Libraries for Distribution is set to Yes, I also add that line to the pod file in case CocoaLumberjack isn't set similarly. In the Framework's Xcode General section, Frameworks and Libraries contains Pods_TheFramework.framework set to Do Not Embed. In the Build Phases section, in the Link Binary with Libraries section, Pods_TheFramework.framework is set to required. Next I create an Xcode app template, run pod install, and edit the app pod file to be: platform :ios, '16.0' workspace 'AppUsingFramework' project 'AppUsingFramework' target 'AppUsingFramework' do use_frameworks! pod 'CocoaLumberjack/Swift', '3.8.5' end post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0' end end end I build the framework, and drag and drop it into the app. I add the following code to the app's delegate: import TheFramework ... AClassInTheFramework.aMethod() The App's target has the following linkage settings: When I build and run the app, there is the following error: If I change the source code in the framework to this: public class AClassInTheFramework { public class func aMethod() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) // DDLogDebug("Some logging") } } Then there is no error and the code runs successfully. This illustrates the problem I've encountered with all the nested frameworks - in this particular case calls to DDLog.add() don't result in an error but calls to DDlogDebug() do, and that has been mirrored with other nested frameworks (for example with Realm, opening a database, adding, finding,retrieving an item all works without a problem, however attempting to use Realm's Results<> API results in a similar symbol not found error). Additionally note that the identical CocoaLumberjack code can run fine when used directly from within the app, i.e., if I add the following code to the app: import CocoaLumberjack func useCocoaLumberjackDirectlyFromWithinApp() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) DDLogDebug("Some logging") } useCocoaLumberjackDirectlyFromWithinApp() Then it runs, i.e. DDLogDebug() can be successfully called from within the app, its only when its called via the framework that the error occurs. Why might I be encountering these issues? I'd have thought either I'd be able to use 100% of the nested framework's public api, or 0% of it (is something is not configured correct), not ~80% which is what I am encountering. Any ideas? TIA

My project is using Fastlane 2.226.0. After converted groups to folders on XCode 16, I got an error when executed below function in Fastfile: get_version_number(xcodeproj: "MyProject.xcodeproj", target: "MyProject") Below is the error message output after I ran fastlane: Unable to find XCode build setting: MARKETING_VERSION

I'm trying to add an Enterprise Apple account with the username and password of my developer account, which has worked once before. Now its giving me the following error: "There was an error while trying to log in: No trusted devices or trusted phone numbers are configured for this account." which doesn't make sense because the 2-Factor Auth works when I login to the website. What am I missing? I think the only thing different is I'm using a different Macbook, but should that make a difference? Has anyone else had this error from Visual Studio?

My application is in flightTest mode. I received my first two crash reports in XCODE /Organizer. The context is well described, and I was able to isolate the locations where very serious errors occurred. My application is connected. I'm missing one piece of data in this crash report: the time of the crash. This will help me see what (in my case) static data was being read on the data server at that time. This will help me investigate. Is it possible to obtain this information?

I've discovered what appears to be a system-level memory leak when pressing any key in Swift UI projects. This issue occurs even in a completely empty SwiftUI project with no custom code or event handlers. When monitoring with Instruments' Leaks tool, I observe multiple memory leaks each time any key is pressed. These leaks consist primarily of: NSExtraData objects (240 bytes each) NSMenuItem objects (112 bytes each) Other AppKit and Foundation objects Has anyone else encountered this issue? How can I fix this behavior? While the leaks are small (about 5-6KB per keypress), they could potentially accumulate in applications where keyboard input is frequent.

The app I'm working on has iOS 16.0 as target. Recently Live Activities support was added, but then it started crashing when running on iOS 16.0 devices. After some investigation, I've found that the culprit was the presence of NSUserActivityTypeLiveActivity and WidgetCenter.UserInfoKey.activityID, even though they were inside an @available(iOS 17.2, *) block. If I comment these two variables, the app work as expected. I've also tried adding #if canImport(ActivityKit) around the code, but without success. But if the @available isn't working, how can I prevent this? It looks like a bug, since the documentation says that NSUserActivityTypeLiveActivity is supported but iOS 14.0+, but I'm pretty sure it was introduced on 16.1. This is the only output I get with the crash: dyld[66888]: Symbol not found: _$s9WidgetKit0A6CenterC11UserInfoKeyV10activityIDSSvgZ Referenced from: <D6EFF120-2681-34C1-B261-8F3F7B388238> /Users/<redacted>/Library/Developer/CoreSimulator/Devices/8B5B4DC9-3D54-4C91-8C88-E705E851CA0F/data/Containers/Bundle/Application/DB6671FF-CB07-4570-BD63-C851D94FAF29/<redacted>.app/<redacted>.debug.dylib Expected in: <C5E72BB5-533F-3658-A987-E849888F4DFC> /Library/Developer/CoreSimulator/Volumes/iOS_20A360/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/WidgetKit.framework/WidgetKit

I implemented the cloudkit function, where users can connect with each other. The problem is, that if User A is doing a friend request and User B is accepting the request. The friend entry is correct visible for User B but not for User A. I can see in cloud kit that after the accepted request, the friend connection is set up correctly, also with the correct userID, but it not showing up for User A (the one that send the request) It's in the public database. In this view you sign in using Apple Sign-In and create a specific user ID. Then you can access a global leaderboard to compare with all signed-in users. Additionaly, there’s a friend tab where you can search for and type in a specific user ID. The target user sees the friend request, can accept it, and then the accepted friend appears in their friend list. However, the original requester doesn’t see the connection after acceptance even though CloudKit shows the records Add comment. I've also tried to add a placeholder in for User A, that e.g he send the request and then has a placeholder where it says e.g pending request to User B. After User B accepted the request, the placeholder will go away and no friend connection is displayed, very strange.

I have been using Xcode 16.2 for a long time. I downloaded it from the developer site. I recently downloaded Xcode 16.3. I was offline on an airplane and I got an error authenticating my account. Since then, I have not been able to sign my apps. I was able to create a new app that worked but in my effort to resolve the problem, I deleted my account and now I cannot add it back. I was getting a "bad URL" error. Now I'm getting "Could not connect to the server." I sent an email to Apple Dev Support and they told me to download Xcode from the App Store. I did that and it gave me the same error. Is anyone else having this problem? If Apple Dev Support cannot resolve it, I don't know how I am going to.

If I install RealmSwift into an ios app using SPM, I have no problems. However if I install it into an ios framework, then when building there is this error: error: missing required modules: 'Realm.Private', 'Realm', 'Realm.Swift' I have discovered that if I change the import statement from: import RealmSwift to private import RealmSwift then doing that makes this build error goes away (but doing that isn't a feasible workaround as I would like to publicly export classes stored in Realm from the framework). There's no point in posting issues with Realm on their support board as its being deprecated and its tumble weeds on their forum. But I would be very interested in hearing from the Apple expects explanation or speculation on: why is importing the same framework via SPM into a framework xcode project resulting in different behavior then when importing it into an app? why would changing import to private import make the build error go away? TIA

I'm trying to rewrite an old AppleScript mail rule that I used extensively as a Mail extension using the MailKit framework and I've run into an issue. Previously, when developing the script, it was possible to debug it by selecting the message I wanted it applied to and choosing the Mail.app menu item "Message/Apply Rules" This would re-execute my script and I could iterate over it as many times as I liked while developing. I haven't found any great way of doing this for my extension with a MEMessageActionHandler. The closest I've found is to forward the message to myself and wait for it to come back in again over the internet, at which point the extension would get executed again. Needless to say, this makes debugging my MEMessageAction handler much slower. I've tried a number of things in Mail.app to try and get it to re-execute my extension with a particular message without any luck. Does anyone know of a good process for debugging a MEMessageActionHandler that doesn't involve forwarding the message to myself over and over and waiting for it to come in each time?

If you have two video segments, one HDR and one SDR, next to one another in a composition, the SDR one appears dark, since its max luminance will be lower than the max luminance of the HDR clip. iMovie handles this well by (reverse) tone mapping the SDR content to make it look HDR in an HDR composition. This is what I want to achieve. I've looked into algorithms to do this, and the best that I can find is the conversion from RGB to YCbCr described in Table 4 of BT.2020, followed by conversion method A (Section 4.2, table 4) of BT.2446-1. I have these implemented in a Core Image kernel, available at this repo. The issue that I'm seeing is that the colors are still much too hot, and while there are frames that appear close to properly tone mapped, it doesn't come close to the accuracy of iMovie's approach. If someone is an expert in colorimetry, etc., I'd really appreciate a breakdown of what I'm doing wrong here. To be specific: Assuming non-constant luminance for the YCbCr conversion Using a Metal Core Image kernel for the actual tone mapping The video composition uses Core Image filters directly The video composition is using BT.2020 colorimetry and the PQ transfer function. Below is a comparison of two screenshots, one using an unaltered HDR asset, and the other using the same asset transcoded to SDR with QuickTime, and reverse tone mapped to HDR for playback. Is there something I'm missing?
