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’ve noticed a good number of strange problems in the IOS development process, so I’m going to track them here. If they’re resolved at some point, I’ll note it. At least in my first attempt, letting Appleconnect build my code resulted in a build with no errors that could not be submitted for review. The solution for me was to build from Xcode. It took a while to stumble on that, so if you have problems with one way, try the other. Xcode doesn’t show Info.plist by default. This is a particularly nasty bug that caused a great deal of trouble, being the biggest reason I had so much trouble getting my first app submitted for review. The only way I found to get around it was to make a small change to one of the items under the Info tab under the project name/icon in Xcode. Then, the Info.plist showed up! SwiftUI and SwiftData are siloed off from each other, so if you have a list, the view is controlled by SwiftUI. This means that if a user moves an item in a list, SwiftData is not informed. If the user quits the app, the order will revert to the last saved version! So you must resort to tracking the order in your code and adjusting your query accordingly.

In my Mac's Settings -> General -> Storage -> Developer -> (i) I have a series of entries for "bridgeOS", all 2.49 GB except one that is "zero". Do I need these? Can I remove them? I am only doing "normal" iPhone / iPad development. (There was some previous mention of this here: https://developer.apple.com/forums/thread/711279 with no feedback.)

I am new to Xcode and coding in general. I am trying to resolve an issue with my CI in GitHub, which I think is coming from a path issue. To summarize my approach: I start by creating a GitHub repo, I then clone that to a outer folder (e.g., TEST) on my desktop, which results in desktop/TEST/TEST/[github files]. When I go to create my Xcode project, it always forces me to create a new folder resulting in desktop/TEST/TEST/TEST/[xcode files]. I want the Xcode files to sit in the repo folder so its desktop/TEST/TEST/[github & Xcode files]. I thought I could drag and drop them in but get a popup blocking it. Any thoughts on how to address this. Thank you in advance.

When launching the SimpleWatchConnectivity sample in a simulator (iOS 18.2 + watchOS 11.2), almost all the functionality works, but TransferFile does not work. The error is the following: -[WCFileStorage persistOutgoingFileTransfer:] error serializing file transfer <WCSessionFileTransfer: ...> due to Error Domain=NSCocoaErrorDomain Code=4866 "Caught exception during archival: This object may only be encoded by an NSXPCCoder." How can it be fixed or worked around?

Hello, I am an iOS and Android mobile application developer. However, I have a major issue on the iOS side, and Apple has not resolved this problem for years. My app is an internal company application, so I cannot publish it publicly. This is where the real issue begins. When I distribute the app to my users via an invitation code, any updates I release take a week or even months to appear on their devices. Users have to uninstall the app, go back to the "Purchased Apps" section in the App Store, and reinstall it. Since the app is private, it doesn’t appear in the regular App Store listings. How can I explain this complicated process to my staff, some of whom have limited technical knowledge? Why doesn’t the update button appear, forcing users to navigate to the "Purchased Apps" section for updates? The app doesn’t need to be visible to the general public, but at least let the update button appear when users find the app in the "Purchased Apps" section. I am currently forced to use TestFlight. However, there is another issue: the approval process for TestFlight takes about four days, which is three times longer than the publishing approval process. I am seriously frustrated by this poor user experience. I’ve become disillusioned with Mac and iPhone because of these problems.

When I'm inspecting a WKWebView in a simulator and the WKWebView loads a local URL with a port number, I've found that most features of Safari dev tools that worked in iOS 17 are broken in iOS 18. Here are the steps I'm taking: Set up a WKWebView with isInspectable = true that loads a local URL, e.g. https://www.local.mydomain.com:3000 Install a self-signed SSL certificate on a simulator for www.local.mydomain.com Run my app on the simulator The WKWebView loads successfully In Safari on my Mac, I can select the WKWebView and open dev tools to inspect it If the simulator is on iOS 17, this works fine, no issues. But if the simulator is on iOS 18, Safari dev tools are mostly broken. I can tell that there is a connection to the WKWebView because the Network tab logs the requests that I expect. But I cannot use any of the other dev tools features: Elements, Sources, Console, etc. Has anyone else encountered this? Is there a workaround?

Hello, Since Xcode update to 16.1, I can't open some of my storyboard files in Interface Builder. When I click on a storyboard, Xcode takes a long time to load, then crashes. I dont have any errors or warnings and everything works well, I can build and distribute the app, just I can't use my storyboards. MacBook Pro M1 on Sequoia 15.1.1 Any help is welcome!

Background: We are developing an App for both Windows, Android and iOS. Our process is that virtually every pull request must be tested by a tester before being pushed to the main branch. Up until now, we have been distributing the 3 versions to our testers via Microsoft AppCenter. Unfortunately, AppCenter is stopping per 31 March 2025 and we are looking for an alternative method. As the Play Store isn't really useful for us for distributing android apps (a test build can take a few hours before appearing according to their documentation), we may have to look into setting up our own distribution website for our apps. As such I was wondering, rather then using Test Flight for iOS, to also distribute the iOS app via our own website to our testers as it would be easier for our testers to have everything together. Even though our apps are build and signed using an "ad hoc" provisioning profile, it's still not possible to just install the .IPA files just by downloading it. The actual question: So my question is, how can I install our app to our testers from a website. Do I have to set the link as something specific? Or has AppCenter been using a trick not available to us mere mortals? To clarify: I am only asking for distributing to our testers using the ad hoc provisioning profile with the test devices registers at apple. I am NOT asking for distribution to end users, that goes via the App Store as usual.

computer specs: MacBook Pro 14in 2023 m2 pro 16gb macos ver: Version 15.1 Beta (24B5009l) Issue: When I open xcode on my Mac, it unexpectedly quits every time. I have disabled internet connection, it doesn't work. I have uninstalled and install again on appstore, it still doesn't work. I've open the app in another user on my laptop, it doesn't work. The problem report generated from the quitting Xcode is too long so i put it into the attached text file: Report Log when it reported quit unexpectedly

How can I add navigation to an existing program. I coded this as per youtube video: var body: some View { NavigationView { VStack { NavigationLink(destination: viewdetail()) { Text("click") .frame(width: 300, height: 150, alignment: .center) .background(Color.gray) .foregroundColor(.black) } } } It doesn't work. If I comment out the rest of the program it works. I have VStacks and HStacks and functions after the navigation code. Please help.

Hi everyone, Since a couple days, I can't launch my watchOS widget extension in the Xcode simulator. After launching the scheme in Debug or Release, I always end up with Xcode stuck on "Waiting to attach to watchOSWidgets on Apple Watch Series 9". I already uninstalled and reinstalled Xcode and cleared all Xcode related folders in Library. I also tried to use Debug > Attach to process, then Xcode goes into "Running watchOSWidgets on Apple Watch Series 9" but no widgets are installed, neither the app so I cannot debug anything. I tried on different simulators, always end up with the same problem. However, the watch app scheme works fine, in Debug or Release, it is only the widgets extension which doesn't work anymore. This seems related to my computer, because if I create an empty project with a default watch widget extension, I still have the same issue. I really don't know what to do... Does anyone has a clue ? Thanks

It only seems to happen in the real app I am working on and not within any of the test apps I make. Its lasted a few Xcode versions. Don't know if this is widespread to the point of having a name?

I'm using xcode 16.1 withSwiftUI. I want to know how to call a function passing in an array. Also I need to know how to declare the function receiving the array. I currently have: func myfunc(costa: [Double] { some code } I call it like this: myfunc(costa:[ ]) It's an array of Doubles. I don't get any errors but the array is always empty even though it's not empty on the sending side. Please help. Thank you.

I saw in the Xcode 16 release notes that on-device debugging is no longer available on watchOS prior to version 7.0, but I can't even get a signed, compiled app to run on an older watch. The current version I have live in the App Store works just fine on 4.3.2. I have changed no code, I just started building the app with Xcode 16, and now it won't launch on older watches. Is it no longer possible to update an app for older watches?

We use a local swift package in 6 of our app extensions. The product from the local package that we link to each app extension is a dynamic framework. And while the dynamic framework is copied into the final app bundle once, the resource bundles of each target that comprise the dynamic framework is copied into each app extension. I'd much rather have the bundles be copied into the dynamic framework once to prevent app bloat. Here is a visualization of the issue: . └── MyApp.ipa/ ├── MyApp (executable) ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle ├── MyDynamicFramework_TargetC.bundle ├── Frameworks/ │ └── MyDynamicFramework.framework/ │ ├── TargetA │ ├── TargetB │ └── TargetC └── PlugIns/ ├── Widgets.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── Intents.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── IntentsUI.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── NotificationContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── RichPushContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle └── NotificationService.appex/ ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle └── MyDynamicFramework_TargetC.bundle Notice that the resource bundles of Target A, B, and C are copied multiple times causing an unhealthy app size. I'd either like the resource bundles to be copied into MyDynamicFramework or copied once into the app bundle and let the app extensions reference them. Given the SPM + Xcode linking is a black box for the most part, how would I accomplish this?

Happy to have a new MacBook Pro M4 now - the new machine was setup from time machine backup of my old MacBook Pro M1. Sadly Predictive Code Completion does not work on the new M4 (it was working great on the M1). Xcode shows as downloaded component: Predictive Code Completion Model [com.apple.fm.code.generate_small_v1.base: 500.1.81600.13.200772,0] [com.apple.fm.code.generate_safety_guardrail.base: 1.6.81619.13.200716,0] [com.apple.gm.safety_deny.input.code_intelligence.base: 32024010.20241007.171244.100.377,0] [com.apple.gm.safety_deny.output.code_intelligence.base: 32024010.20241007.171244.100.377,0] (Installed) Things I already tried: Removed and reinstalled Xcode 16 (also latest beta). Disabled/enabled Xcode Editor Settings for predictive code completion Many many reboots Removed Xcode cache Maybe the downloaded Model is somehow locked to the old machine? How can I remove, redownload or reinstall it again? Thank you very much. Tobias

I am writing a package in Swift using Xcode 16.1 (swift-tools-version: 6.0) and am trying to use features that became available in later versions of macOS and iOS. The following line naturally causes a compiler error when compiling against 'My Mac': let match = "test-string".firstMatch(of: /-(.+)/)! 'firstMatch(of:)' is only available in macOS 13.0 or newer I can of course fix this by using @available(macOS 13.0, *), but there are dozens of methods and I would prefer to use the platforms property in the Package file like this: platforms: [ .macOS(.v10_13), .iOS(.v16) ], However for reason that are not clear, this does not work and the compiler errors remain. I have tried cleaning, removing derived data etc. What I am doing wrong?

I try to use "Download container" on "Devices and Simulators". But on iOS 17, xcappdata file size is 4KB and ''AppData" folder is empty. On iOS 15, xcappdata file size is 2MB and success downloaded. Xcode show these error when I unplug iOS 17 and plugin iOS 15. The system failed to get a list of files on the remote device. Domain: com.apple.dt.CoreDeviceError Code: 7001 User Info: { DVTErrorCreationDateKey = "2023-12-12 07:39:24 +0000"; NSFilePath = ""; } -- Unknown response: { XPCErrorDescription =&gt; Connection interrupted } Domain: com.apple.dt.remoteservices.error Code: -1 -- System Information macOS Version 14.2 (Build 23C64) Xcode 15.1 (22502) (Build 15C65) Timestamp: 2023-12-12T15:39:24+08:00 PS. I had turn on [Airplane mode] on iOS 17.

When I attempt to preview my code, I encounter an error message stating, “Cannot preview in this file: Failed to launch (App Name).” This issue is specific to this particular app. I attempted creating a new project, and that works fine. This is what it says in the diagnostics: | [Remote] JITError | | ================================== | | | [Remote] LLVMError | | | | LLVMError: LLVMError(description: "The file was not recognized as a valid object file")

Our company has been trying to register for the Apple Developer Enterprise Program since September 15, 2024. However, it wasn’t until early November that we received an email requesting our business information. Following that, we contacted Apple’s team on November 15, 2024, to answer their interview questions. Now, more than a month has passed since that call, and we still have no idea about the status of our approval. When I check the account, it always shows 'Your enrollment is being processed. Your enrollment ID is 8K8SXNKA89.' I’ve also emailed Apple Support but have not received any further response. How much longer will this process take? Apple’s handling of this is excessively slow and frustrating
