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)

We are transferring ownership of an app from one org to another. Most things seem to be transferring as expected thus far according to this page, with the exception of our Xcode Cloud configuration and workflows. I understand that they are connected to source code (Github in this case), so those would probably need to be reconnected, but is there any way to get some of the configuration/workflows transferred?

I upgraded xcode to 16.2 and found that the txt file generated by Write Link Map File is different from before, no longer containing detailed data. So, how to set it up to obtain the same link map file as the previous xcode version. # Path: /Users/....../xxx.app/__preview.dylib # Arch: arm64 # Object files: [ 0] linker synthesized # Sections: # Address Size Segment Section 0x00004000 0x00000000 __TEXT __text # Symbols: # Address Size File Name

I have an issue when i use external tester with a public link and emails. Test fly is well installed but when i have to open the app, it just charge as seen in the screen.

We are renaming the project and a Static Library the is critical to the operation on the app is not found during compiling. We have the same project working fine. We have reviewed the project.pbxproj file and searched for erroneous linking, reviewed the Target settings and there is nothing obviously wrong. (Copied and secured the original) Typically workflow is: Clean Delete Derived Data dir D/l Swift Packages Build/Run The team has many years using Xcode / Swift and the project and this is not clear how to resolve. We have scoured SO and the solutions do not apply. Facts: -No cocoapods -Search Paths all set Linker all set Thoughts?

I can use devicectl to copy single files from a device fine using: xcrun devicectl --verbose device copy from --user mobile --domain-identifier <BUNDLE_ID> --domain-type appDataContainer --device <DEVICE_ID> --source Documents/Screenshots/0001.png --destination Screeshots/0001.png but when there are many files this can get pretty slow. Is there a way of recursively copying an entire directory? I've tried this: xcrun devicectl --verbose device copy from --user mobile --domain-identifier <BUNDLE_ID> --domain-type appDataContainer --device <DEVICE_ID> --source Documents/Screenshots --destination Screeshots but nothing is transferred and it times out eventually with the error: ERROR: The specified file could not be transferred. (com.apple.dt.CoreDeviceError error 7000 (0x1B58)) ERROR: The operation couldn’t be completed. The file service client failed to read data from the network socket because we timed out when waiting for data to become available. (NSPOSIXErrorDomain error 60 (0x3C)) NSLocalizedFailureReason = The file service client failed to read data from the network socket because we timed out when waiting for data to become available. Xcode itself can do it with the "download container..." option, but I'd like to be able to automate it.

We'd like to give account holder role to another person in our team and when I tried to verify my account and post id photos in Developer app, I always got the next answer: 'Unable to Send Information, Your information could not be sent due to a connection error' with 2 buttons (try, cancel). I tried it many times with same result. I don't know what is wrong.

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.

Xcode 16.3 simulator slow to load - unusable

Hello, Two months ago, I tried to enroll in the Apple Developer Program and provided official documents such as my ID and passport. However, I was repeatedly asked to upload them again until my account was declared no longer eligible for use in the Apple Developer Program. I don’t know why my ID was rejected. I tried uploading a regular photo of the document, I tried a scan, and I tried various formats, but nothing worked. Now I want to try again and enroll, but the button is not clickable. Can you please guide me through what went wrong and how I can try again? Thank you.

I have a swift project with a Watch companion. Since the update of Xcode in 16.3 version after updating MAcOs , Watch OS, iOS to the latest version . It is quasi impossible for me to make Xcode work with my series 10 Watch. I have a lot of alert box, messages in the "device & Simulator" tool like this Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. And many message telling me that Xcode is preparing the Watch , then that it has lost the connexion. I have to wait some minutes after EACH run of the App to test it again. This is very annoying . Some of the alerts I have : And the best to know , is that I can run the APP outside of Xcode , it works, Connects to the iPhone, fetch data and so. the iPhone sees the Watch without and problem. Reboots can solve for a few minutes the problem. But that is not a solution.

Upon updating to Xcode 16.3, my StoreKit2 unit testing suite encountered a malfunction. let result = await product.purchase() The code snippet above simply halts execution, preventing the task from progressing. In a regular environment, everything appear to function correctly.

Bluetooth connection is very buggy since updating to iOS 18.4. Beta X (with all betas) Airpods Pro 2 most of the time don't connect directly with my Iphone 15 Max. I have to disable bluetooth and then the connection works find. This issue ist not only with my Airpods, but also with the car, ... Very annoyinig. I reset the network settings. But this didn't help. Any suggestion how to fix this? I hear from quite a few people that they have bluetooth issues with iOS 18.X. Hope Apple fixes this soon.

So I will summary an issue one of our clients has asked us on GitHub: https://github.com/pendo-io/pendo-mobile-sdk/issues/233 Project that is a custom framework that uses different SPM packages (one of them is Binary package), we have our main logic inside that framework and we have different targets that use this framework, everything works on the simulator, but running the app on the actual device provokes a crash saying "Binary framework was not found". We have like 20 other SPM packages that work fine, this is the first one we have an issue with. Please note I understand that SPM will not copy paste the Binary for the magic framework as it does for the apps so I suggested to embed it manually. So my question is what the best(easy) way to do it. Please refer to the following issue for more details: https://github.com/pendo-io/pendo-mobile-sdk/issues/233

Hello Friends, We have a strange bug that Xcode is deploying static binaries from within .XCFramework into the CONFIGURATION_BUILD_DIR An example of our xcframeworks structure is: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>AvailableLibraries</key> <array> <dict> <key>BinaryPath</key> <string>libglfw3.a</string> <key>HeadersPath</key> <string>Headers</string> <key>LibraryIdentifier</key> <string>macos-arm64_x86_64</string> <key>LibraryPath</key> <string>libglfw3.a</string> <key>SupportedArchitectures</key> <array> <string>arm64</string> <string>x86_64</string> </array> <key>SupportedPlatform</key> <string>macos</string> </dict> </array> <key>CFBundlePackageType</key> <string>XFWK</string> <key>XCFrameworkFormatVersion</key> <string>1.0</string> </dict> </plist> for open source creative coding toolkit https://github.com/openframeworks/openFrameworks Can you see any issues in the above. Some ideas for me is to generate xcarchive instead of deploying the .a in the xcframeworks, however that does not explain the include being packaged there, so I think this might be a Xcode issue

I'm using RevenueCat in a Flutter app to manage in-app subscriptions. On iOS, the subscription products load and display correctly when running in debug mode on a real device. However, when I upload the app to TestFlight, the products fail to load — I get an empty list or no products shown at all.

Xcode 16 seems to „forget“ a swift package within a subfolder of a root package after restart or shut-down. I have the following project structure, which also resembles the directory structure on disc: MyPackage - Package.swift - README.md - Sources - MyPackage - Tests - MyPackageTests - Tools - MyGenerator // <- after restart this folder is not visible in the Xcode project navigator - Package.swift - Sources - main.swift - Tests MyGenerator is a standalone package which is used during development of MyPackage to generate source code files for MyPackage based on text file input. Essentially an executable target script which I can run within its folder with: swift run MyGenerator someInputFile.txt MyPackage does NOT use MyGenerator as a dependency, nor do I want this tool listed as a dependency in MyPackage Package.swift file. Yet MyGenerator is part of the same Git repo, as it documents the changes to the tool on how to generate source code for MyPackage. Both packages are developed in tandem. MyGenerator itself defines dependencies in its Package.swift file, which are unrelated to the functionality of MyPackage. After restart of Xcode or even just a longer shut-down period the MyGenerator subfolder is not visible in the Xcode project navigator, the /Tools folder is empty. I have to manually add the sub package via Add files to "MyPackage" -> Move files to destination every time. How can I solve that Xcode remembers the sub package unter /Tools? Edit: I am using Xcode 16.2

Hello. We're developing an app with Flutter that receives VoIP calls. However, when the app is in the background or closed, the push notification arrives, but the call doesn't. It works perfectly when the app is open. We use Firebase, Flutter, and JANUS WebRTC. We need to know what type of permissions or actions we should consider so that the app opens when it receives a call. How can we resolve this issue? Thank you very much.

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.

Unable to add a user on my app store connect. I get "This field is invalid" error each time. I have tried with a variety of different emails, same error.

I want to build an ios .xcframework (for external delivery) and .framework(for internal debugging) in order to package some code to a customer for incorporation into their app. My framework has a dependency upon RealmSwift, which I've added using SPM. There is a warning saying Module RealmSwift was not compiled with library evolution support. And when building SwiftVerifyEmittedModuleInterface fails with an error saying "missing required modules: 'Realm.Private', 'Realm', 'Realm.Swift'" By default, Build Libraries For Distribution was set to YES, however if I turn it off then the warning and error go away and I can cleanly build the framework. I've been attempting to get a good understanding of this flag and if it should be used or not, most material says yes but doesn't go a good job of explaining why. However anyway I can't get the framework to build with RealmSwift as a dependency without turning off this flag. Therefore is that ok to proceed down that route? Does the fact the xcframework will only ever be distributed to one consumer affect decisions (i.e. binary compatibility etc.) Thanks
