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 want to statically link xcframework as binaryTarget in Swift Package, but it is copied into the product as dynamic when the Xcode build. How to use xcframework in SwiftPackage and statically link it into iOS product? The Package.swift content and the project are: The WebP.xcframework is static: The Xcode Build Product's WebP.framework is dynamic:

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.

When I build UITabBarController on (iPad + iOS18), selectedImage on each tabBarItems don't appear. (SwiftUI TabView can change iconImages by state change, so no problem on SwiftUI.) Could someone tells me how to solve this problem? sample project which produce the problem: github before after

When I thought Xcode could not get any worse, here's the most absurd thing I have ever seen developing software in almost 20 years of work. When building a project, which I haven't touched lately, and last time it was building just fine, it raised errors on a class that doesn't even belong in any way to such project, it only exists in another one. To clarify, we're talking of a project written in C++ which runs only on mac, which is failing due to linker errors, where the linker can not find symbols of a class living in a different project and that is not referenced in any way inside this project. I mean, really? how does Apple manage to make Xcode more and more unstable by the minute? Starting from Xcode 15.1 I was already experiencing much longer building times, due to the fact that it doesn't manage the cache properly and is rebuilding lots of stuff every time..

I have a Mac Mini (M4) running macOS Sequoia 15.3.1. I very recently downloaded and installed the current version of XCode from the app store. I have not added any extensions - it's a vanilla, un-customized, un-enhanced installation. I have two user profiles (accounts) on my Mac: one Administrator and one Standard, each using a different apple account. I am using the Standard user account to learn XCode. When I attempt to set up a project, I get an error message when Xcode initially tries to save the (provided) project template file. The error states: "Failed to save Project2.xcodeproj. The backing file has been modified outside of XCode." I am using a NAS drive to store my project file. I have also tried saving it to the Desktop. It makes no difference to the error wherever the file is being saved. Similarly, I tried changing the Standard user account to an Administrator account to see if it was a privileges problem. Again, it made no difference to the error message. (So I changed the account back to a Standard user). I have tried googling the error but I only find references to problems related to extension/add-in products to XCode: none of which have I added to my XCode installation. I am attaching screenshots of the steps through the project creation process. Hopefully someone can tell me what I am doing wrong or what the problem is. Thank you.

Hey, I've been having a lot of problems with Xcode 16 not seeing changes made to code in local Swift packages (the packages are inside the root directory of the project). Whenever I make any change like renaming a variable or type, or adding new methods or whatever, autocomplete doesn't see those changes and when I type in that new type/variable manually it gives me an error. However, building the project still works fine, even with the errors never going away. The only way for it to notice the code changes is to clean the project and build it again which takes a long time. At first, I thought this was connected to the new "Explicitly built modules" feature in Xcode 16, but I turned it off and it still happens. Any ideas what I can try? I'm on the latest Xcode version, but this problem has been happening since Xcode 16 originally came out. Thanks! Dennis

Hi, This maybe somewhat confusing, but please bear with me. I currently have an app in the App Store that supports iOS and tvOS. But the tvOS version was a separate app during the development process. I'd like to combine the iOS and tvOS app into one project so its easier to handle and keep track of internally. Can I upload the new Apple TV version to the same place where the current one is, or would I have to delete the current Apple TV version before uploading the newly combined version? I hope I made that clear enough :-) Thank you, Dan Uff

Neither a google search, nor a search of the Apple forums give me a clue as to how to locate or fix the following message I get from Xcode. CLIENT: Failure to determine if this machine is in the process of shutting down, err=1/Operation not permitted This error message came from attempting to build and execute an iOS App which ran just fine the last time I built it. Now, that was actually a little over two years ago. This is an iOS app, which I've run successfully for more than a year on macOS, and that, "My Mac (Designed for iPad)", is what my build target for this run was. Any ideas? Anyone? If this is a "known condition", just why doesn't a friendly internet search or a search of the Apple forums NOT tell me what it means, or what causes the message. Of course, I've upgraded the OS a few times, and updated Xcode as well, but have just not had any time to monkey around with my pet code project. Now that I've gotten some time, and I want to see what's new since March of '23, I finally remember where I stashed my code repository and decided to take it for a spin. Sure, I expect(ed) to see Xcode tell me that the version of Swift has been updated, and maybe some code constructs need to be fixed. But, NO, the code compiles fine. The first build attempt told me that I needed to update my provisioning profiles, and sign-in and agree to the updated developer agreements, which I did. Not so unhelpful was the code window in the debugger: libswiftCore.dylib`swift_willThrow: -> 0x1aeb7b2a0 <+0>: pacibsp 0x1aeb7b2a4 <+4>: str x19, [sp, #-0x20]! 0x1aeb7b2a8 <+8>: stp x29, x30, [sp, #0x10] 0x1aeb7b2ac <+12>: add x29, sp, #0x10 0x1aeb7b2b0 <+16>: adrp x8, 365651 0x1aeb7b2b4 <+20>: add x8, x8, #0x88 ; _swift_willThrow 0x1aeb7b2b8 <+24>: ldapr x8, [x8] 0x1aeb7b2bc <+28>: cbnz x8, 0x1aeb7b2cc ; <+44> 0x1aeb7b2c0 <+32>: ldp x29, x30, [sp, #0x10] 0x1aeb7b2c4 <+36>: ldr x19, [sp], #0x20 0x1aeb7b2c8 <+40>: retab 0x1aeb7b2cc <+44>: mov x0, x21 0x1aeb7b2d0 <+48>: mov x19, x21 0x1aeb7b2d4 <+52>: blraaz x8 0x1aeb7b2d8 <+56>: mov x21, x19 0x1aeb7b2dc <+60>: b 0x1aeb7b2c0 ; <+32> Still not much to go on. I decide to see if it was a macOS vs. iOS issue, so did a clean build folder and tried running on an iPad simulator, "iPad (10th generation)". Now, I have a blank white screen on my simulator and not much to go on in the code window. import SwiftUI @main struct JottoApp: App { Thread1: Breakpoint 1.1 var body: some Scene { WindowGroup { ContentView() } } init() { UITableView.appearance().backgroundColor = UIColor.clear } } Any and all help with this error message will be appreciated.

I am developing a game that has 3 team members. I can manually start up 3 simulators and run the game for developing/testing but seem like there should be a simple way to click build/run and have it launch on all three automatically. Does anyone know how to do this or if its even possible without writing some scripts?

We are experiencing networking issues in our iOS application when it is built with Xcode 16 or later. Our app includes a video conferencing feature that works reliably when built with Xcode 15 or earlier — we can sustain hour-long video sessions without interruption. However, when the app is built using Xcode 16 or higher, network connections drop after 2–3 minutes during a session. This triggers an auto-reconnect, which succeeds, but the connection drops again after another 2–3 minutes. This loop continues indefinitely. Key Details: The issue only occurs in TestFlight builds. When running the app via Xcode debugger, the issue does not occur. The issue is consistently reproducible in TestFlight builds created with Xcode 16 or later. TestFlight builds created with Xcode 15 do not exhibit this issue. All the videoconferencing runs on C and C++ code What We’ve Tried: Reviewed Xcode 16+ release notes but found no relevant changes or deprecations. Verified app configuration and entitlements. Confirmed that no app-side changes occurred between the working and broken builds. Request: We’re seeking guidance on what changes in Xcode 16+ could be affecting networking behavior in release/TestFlight builds. Any insight into relevant build settings, compiler changes, or runtime behavior differences would be greatly appreciated. Thank you in advance for your assistance.

Can we use Icon Composer to drive an app icon for iOS 26 apps today? I get errors uploading a build to TestFlight internal testing about missing App icon dimensions for an iOS 26 app.

I'm integrating Apple Pay with PayFort in a Swift iOS application, and I’m currently working on preparing a valid purchase request using Apple Pay, as described in PayFort’s documentation: 🔗 https://docsbeta.payfort.com/docs/api/build/index.html?shell#apple-pay-authorization-purchase-request The documentation outlines the following required parameters: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod apple_displayName apple_network apple_type Optional: apple_applicationData I understand these should be derived from the PKPayment object after Apple Pay authorization, but I’m having trouble mapping everything correctly. Here’s what I’m seeing in code: payment.token // Returns something like: <PKPaymentToken: 0x28080ae80; transactionIdentifier: "..."; paymentData: 3780 bytes> payment.token.paymentData // Contains 3780 bytes of encrypted data payment.token.paymentData.base64EncodedString() // Returns a long base64 string, which at first glance seems like it could be used for apple_data, // but PayFort doesn't accept it as-is — so this value appears to be incomplete or incorrectly formatted I can successfully retrieve the following values from payment.token.paymentMethod: apple_displayName apple_network apple_type However, I’m still unsure how to extract or build the following in the format accepted by PayFort: apple_data apple_signature apple_header apple_transactionId apple_ephemeralPublicKey apple_publicKeyHash apple_paymentMethod These may be contained within the paymentData JSON, but I’m not sure how to decode it or if Apple allows decrypting it in a way that matches PayFort’s expected format. How can I correctly extract or build apple_data, apple_signature, and apple_header from the Apple Pay token? Also, how should I handle the decryption or decoding (if necessary) of paymentData to retrieve values like apple_transactionId, apple_ephemeralPublicKey, and apple_publicKeyHash? If anyone has successfully set this up or has example code that bridges Apple Pay and PayFort’s expected request format, it would be super helpful! Thanks in advance 🙏

Running macOS 15.4.1, Simulator 16.0 (1042.1), various iOS devices (iPhone 16, iPad 13" M4) I log into iCloud and enable iCloud Drive. Running the Files app, I noticed that I can click on "flat" documents (PDF, JPEG, etc) and they work. However, when I click on "package" documents (e.g. represented by a directory behind the scenes), I get a normal download progress, but then an alert "The operation could not be completed. No such file or directory". This seems to happen with all package documents, e.g. Keynote documents or Reality Composer objcap documents. It does not happen on actual devices logged into the same account. I've tried completely deleting and rebuilding the simulator instances in question, with no success.

Hi, I am able to build my iOS app successfully, developed in objective-C with iOS 17.5 SDK and Xcode 15. Due to requirement of Appstore we are trying to build with iOS 18 SDK and Xcode 16. When building getting error in LAEnvironmentState.h file: a) "Property requires field to be named" b) "Expected member name or ';' after declaration specifiers" Same app when opening with Xcode 15 gets build without any issue. Any help/suggestion would be appreciated.

Hello All, I see an issue while running the Notification content Extension on simulator without checking the "Copy only when installing in app target -> Build Phases -> Embed App Extensions" If I check "Copy only when installing in app target" then only it is working. Can someone please confirm if Notification Content Extension is working on simulator. If yes how can we do that. Please share the details

Hi all, I’m running into a persistent linker error when building my Unity 6 project (IL2CPP, iOS target) that calls a Swift method via an Objective-C++ wrapper. Despite following all known steps, I keep getting: Undefined symbols for architecture arm64: "_placeGeoAnchor", referenced from: _GeoAnchorTrigger_placeGeoAnchor in libGameAssembly.a ... ld: symbol(s) not found for architecture arm64 I’m trying to place a persistent AR anchor at real-world GPS coordinates (so that the same asset can appear at the same location for a returning user). Since I’m targeting iOS, I can’t use Google’s geospatial anchors (but I sooo wish I could--please apple I beg of you stop being so selfish lol). I've already done these things: Swift file is added to Unity-iPhone target. .mm and .h files are in Unity-iPhone target under Compile Sources. Bridging header is set to Unity-iPhone-Bridging-Header.h. Generated header name is correct (GeoTest-Swift.h). Build Active Architecture Only set to No. Function has attribute((visibility("default"))). Unity project uses IL2CPP scripting backend. Yet I'm still getting the same linker error — it appears Unity (via IL2CPP) references the function, but Xcode doesn't link it. It’s something small that’s being missed with how IL2CPP links native symbols? Or maybe I need to explicitly include something in Link Binary With Libraries? I’ve verified symbol visibility and targets repeatedly. I’ve built AR features in Unity before (for Quest), but this is my first time trying to bridge C# → Objective-C++ → Swift in this way for a geolocation-based AR anchor for an iphone. I'm going crazy, I’ve been stuck on this for 12+ hours now, so any insight or nudge would be deeply appreciated. SPECS: Macbook Pro M4 Pro--Sequoia 15.4 Unity 6000.0.45f1 IPhone 11 iOS 18.4 Xcode 15
