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'm attempting make to make a distribution build of an app. In the Xcode target the supported destinations has only iPhone and build active architectures only is set to NO. I created an archive, then selected Distribute App/ Debugging, but then got this error: Provisioning profile "iOS Team Provisioning Profile: com.abc.def" doesn't include the currently selected device "DT-iPad-XXXX" (identifier YYYY-YYYYYY). I've no idea what this device is, it's nothing to do with me, somebody must have added it to the provisioning profile. But that should be beside the point shouldn't it? Because this device has never ever been connected to my Mac/Xcode and so can't be "the currently selected device". So I tried again. I changed build active architectures to YES and connected an iPhone to the Mac/Xcode and created an archive again. But it was the exact same error. What's going on, why is Xcode saying this iPad is the currently selected device when attempting to make a distribution?

Hi everyone, I have created an Apple Developer Account for our company here in India. We are yet to launch our iOS Mobile App. However, recently we have also opened our branch in UAE and we want to change all the account details as per UAE’s Branch - Organisation’s name, DUNS Number, etc. I have submitted the change request of the details in the same developer account. Is it alright? How much time does Apple take in this regard? Do we have to create a new account for this or amendments can be made? Best Regards

Hi everyone, I'm working on an NFC-related app using CoreNFC with APDU commands to read and write tags. I’ve encountered an issue when trying to handle the scenario where the user cancels the NFC session. Here’s what’s happening: When a user cancels the NFC session manually (e.g., by tapping "Cancel"), I see an error log indicating tagReaderSession|userCancelled. However, when I explicitly call session.invalidate(errorMessage: "No NFC tag found") in my code to handle a scenario where no tag is detected, the session still shows the error as userCancelled instead of my custom error message. This behavior is confusing both in terms of debugging and for providing feedback to users, as I expect my custom message to appear instead of the generic "user cancelled" message. func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) { // Session becomes active } func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { // Handle tag detection logic } func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) { print("Session invalidated with error: \(error.localizedDescription)") } func handleNoTagDetected(session: NFCTagReaderSession) { session.invalidate(errorMessage: "No NFC tag found") } I call handleNoTagDetected(session:) explicitly when no tag is detected, expecting the custom error message to show. However, the system still shows the cancellation error. Has anyone else experienced this behavior? Is this the intended behavior for CoreNFC, or am I missing something in my implementation? Any guidance would be appreciated. Thanks in advance!

Got a Watch SE recently only to find out that I can't deploy apps to it from Xcode even once. I always get the message "Connecting to Watch" and "Reconnecting to Watch". Tried with Xcode 16 and then with 16.2. Same result. For countless times, I have tried every possible solution posted on this forum and elsewhere but to no avail. Filed a feedback, no reply yet from Apple. Looks like something is seriously broken. Please fix this. FB16122816

I am helping my company to renew the Enterprise Account, this exercise had been running smoothly in previous year. However, we did submit the application almost 1 month in advance, however, no reply or status update received yet. We had raised several tickets in support but helpless, our account is going to expired on 29-Dec-2024, anyone can share what should we do?

The problem is: As per screenshot below, one can only see the lineChart. I have another struct AffiliateView coded under this Chart: import SnapKit import Charts import DGCharts class AffiliateViewController: UIViewController { private lazy var chartView: LineChartView = { let chart = LineChartView() chart.noDataText = "No data available." chart.chartDescription.enabled = false chart.xAxis.labelPosition = .bottom chart.rightAxis.enabled = false chart.legend.enabled = true chart.backgroundColor = .lightGray // For debugging visibility return chart }() private lazy var containerView: UIView = { let view = UIView() view.backgroundColor = .white return view }() override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = .white // Add container view and chart view to the main view view.addSubview(containerView) view.addSubview(chartView) // Add SwiftUI View inside the container view let affiliateView = AffiliateView() let hostingController = UIHostingController(rootView: affiliateView) addChild(hostingController) containerView.addSubview(hostingController.view) hostingController.view.frame = containerView.bounds hostingController.didMove(toParent: self) layout() setupChartData() } private func layout() { // Layout the container view (SwiftUI content) containerView.snp.makeConstraints { make in make.top.equalTo(view.safeAreaLayoutGuide.snp.top) make.left.right.equalToSuperview() make.height.equalTo(350) // Increase the height for the SwiftUI content } // Layout the chart view below the container view chartView.snp.makeConstraints { make in make.top.equalTo(containerView.snp.bottom).offset(20) // Space between chart and the affiliate content make.left.equalToSuperview().offset(20) make.right.equalToSuperview().offset(-20) make.height.equalTo(200) // Set a fixed height for the chart } } private func setupChartData() { let dataEntries = [ ChartDataEntry(x: 1, y: 10), ChartDataEntry(x: 2, y: 20), ChartDataEntry(x: 3, y: 15), ChartDataEntry(x: 4, y: 30), ChartDataEntry(x: 5, y: 25) ] let dataSet = LineChartDataSet(entries: dataEntries, label: "Clicks per Day") dataSet.colors = [.blue] dataSet.valueColors = [.black] dataSet.circleColors = [.red] dataSet.circleRadius = 4.0 let data = LineChartData(dataSet: dataSet) chartView.data = data chartView.notifyDataSetChanged() } } // SwiftUI View remains in the same file struct AffiliateView: View { @State private var customMessage: String = "" @State private var uniqueLink: String = "Your unique link will appear here." @State private var clickData: [Double] = [10, 20, 15, 30, 25] // Example data var body: some View { NavigationView { VStack(spacing: 20) { // TextField for custom message input TextField("Enter your custom message...", text: $customMessage) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding(.horizontal) // Generate Link Button Button(action: generateLink) { Text("Generate Sign-Up Link") .font(.headline) .foregroundColor(.white) .frame(maxWidth: .infinity, maxHeight: 50) .background(Color.red) .cornerRadius(10) } .padding(.horizontal) // Generated Link Label Text(uniqueLink) .font(.body) .multilineTextAlignment(.center) .padding(.horizontal) // You can add a chart here if you want to show it in SwiftUI too /* LineChartView(data: clickData, title: "Clicks per Day", legend: "Daily Clicks") */ } .navigationTitle("Affiliate Marketing") .navigationBarTitleDisplayMode(.inline) } } private func generateLink() { let encodedMessage = customMessage.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) ?? "" uniqueLink = "https://affiliate.example.com/referral?message=\(encodedMessage)" addClickData() } private func addClickData() { clickData.append(Double.random(in: 0...100)) } } As you see, the AffiliateView has been declared outside of Controller View class. The View content was visible before the lineChart was added into this code. Now the View content is not visible anymore. I have tried to increment/decrement values at make.height.equalTo() but to no avail. Could anyone kindly point me in the right direction?

I imported few files in my Xcode project from other projects using drag and drop. Even though the files are copied in the new project and there are no softlinks pointing to the location of other project, the issue is whenever I do a git commit and push, Xcode keeps showing all the projects to commit to rather than just the current project. There seem to be no setting to permanently remove git dependency of other projects. Is there anyway to remove references to other projects?

Is there anyone here who can provide an answer, or is it related to someone who belongs to the App Review department at Apple? We uploaded an app to the App Store and discovered a bug that disables activity. We uploaded an update with the bug fix and now we are waiting for Apple to review the latest version and approve uploading it to the store. Thousands of users are waiting and leaving us. Losses of a lot of money and more importantly - a bad user experience. If there is anyone here who can help us, or knows someone who can speed up the process, we are more than happy!!! It is critical and urgent. And yes, we signed up for Apple's fast track program... It didn't help. Thanks!

I'm testing my App and the preview in Xcode keeps refreezing by itself preventing me from testing my code. It refreshes about once a second despite me not doing anything. Any ideas? Thank you!

Hello, I used to add openssl static libraries (libssl.a, libcrypto.a) that, I created on Mac, and add them after to my C++ project within XCode. With Xcode 14.2 (and before) all works fine. Switching to Xcode 15.2, tons of link errors rise (ld: Undefined symbols). I tried _ld_classic to force use 'old' linker but no success. Rebuild the static libraries with multiple config param or upgrade to recent openssl library does not help. Any clues what went wrong when linking static libraries with Xcode 15.2 project? Thx.

I am getting this error in a couple of places in my code with Task closure after setting Swift 6 as Language version in XCode. Passing closure as a 'sending' parameter risks causing data races between code in the current task and concurrent execution of the closure Below is minimally reproducible sample code. import Foundation final class Recorder { var writer = Writer() func startRecording() { Task { await writer.startRecording() print("started recording") } } func stopRecording() { Task { await writer.stopRecording() print("stopped recording") } } } actor Writer { var isRecording = false func startRecording() { isRecording = true } func stopRecording() { isRecording = false } } While making the class Recorder as Actor would fix the problem, I fear I will have to make too many classes as Actors in the class and in my scenario, there could be performance implications where real time audio and video frames are being processed. Further, I don't see any race condition in the code above. Does the error talk about possible race conditions that could arise if I were to call other functions on the self in future, or the current code itself is not safe?

Hello, Our company trying to register a developer account in BR, but seems all my e-mails is going to nowhere. Since November/2024 i´m trying and no response. I receive the email with the "case id", but after that, no one responds to me. I did the entire process on the website to create the account. It remains pending "under review for up to 48 hours", but they never get back to me. Does anyone have any other contact that can help me? Thanks, Davi Martins Ferreira CEO D-TELECOM

I regularly see questions from folks who’ve run into problems with their third-party IDE on macOS. Specifically, the issue is that their IDE is invoking Apple’s command-line tools — things like clang and ld — and that’s failing in some way. This post collects my ideas on how to investigate, and potentially resolve, issues like this. If you have any questions or comments, please put them in a new thread here on DevForums. Tag it appropriately so that I see it. Good tags include Compiler, Linker, LLVM, and Command Line Tools. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Investigating Third-Party IDE Integration Problems Many third-party IDEs rely on Apple tools. For example, the IDE might run clang to compile C code or run ld to link object files. These IDEs typically don’t include the tools themselves. Rather, they rely on you to install Xcode or Apple’s Command Line Tools package. These are available at Apple > Developer > Downloads Occasionally I see folks having problems with this. They most typically report that basic stuff, like compiling a simple C program, fails with some mysterious error. If you’re having such a problem, follow the steps below to investigate it. IMPORTANT Some IDEs come with their own tools for compiling and linking. Such IDEs are not the focus of this post. If you have problems with an IDE like that, contact its vendor. Select Your Tools macOS has a concept of the current command-line tools. This can either point to the tools within Xcode or to an installed Command Line Tools package. To see which tools are currently selected, run xcode-select with the --print-path argument. This is what you’ll see if you have Xcode installed in the Applications folder: % xcode-select --print-path /Applications/Xcode.app/Contents/Developer Note All of the tools I discuss here are documented in man pages. If you’re not familiar with those, see Reading UNIX Manual Pages. And this is what you’ll see with a Command Line Tools package selected. % xcode-select --print-path /Library/Developer/CommandLineTools There are two common problems with this: It points to something you’ve deleted. It points to something unexpected. Run the command above to see the current state. If necessary, change the state using the --switch option. For example: % xcode-select --print-path /Applications/Xcode.app/Contents/Developer % clang -v Apple clang version 14.0.3 (clang-1403.0.22.14.1) … % sudo xcode-select --switch ~/XcodeZone/Xcode-beta.app % clang -v Apple clang version 15.0.0 (clang-1500.0.38.1) … I have Xcode 14.3 in the Applications folder and thus clang runs Clang 14.0.3. I have Xcode 15.0b5 in ~/XcodeZone, so switching to that yields Clang 15.0.0. It’s possible to run one specific command with different tools. See Select Your Tools Temporarily, below. Run a Simple Test A good diagnostic test is to use the selected command-line tools to compile a trivial test program. Consider this C [1] example: % cat hello.c #include <stdio.h> int main(int argc, char ** argv) { printf("Hello Cruel World!\n"); return 0; } % clang -o hello hello.c % ./hello Hello Cruel World! IMPORTANT If possible, run this from Terminal rather than, say, over SSH. You may need to expand this test program to exercise your specific case. For example, if your program is hitting an error when it tries to import the Core Foundation framework, add that import to your test program: % cat hello.c #include <stdio.h> #include <CoreFoundation/CoreFoundation.h> int main(int argc, char ** argv) { printf("Hello Cruel World!\n"); return 0; } When you compile your test program, you might see one of these results: Your test program compiles. Your test program fails with a similar error. Your test program fails with a different error. I’ll explore each case in turn. [1] For a C++ example, see C++ Issues, below. If your test program compiles… If your test program compiles from the shell, that proves that your basic command-line tools setup is fine. If the same program fails to compile in your IDE, there’s something IDE-specific going on here. I can’t help you with that. I recommend that you escalate the issue via the support channel for your IDE. If your test program fails with a similar error… If your test program fails with an error similar to the one you’re seeing in your IDE, there are two possibilities: There’s a bug in your test program’s code. There’s an environmental issue that’s affecting your command-line tools setup. Don’t rule out the first possibility. I regularly see folks bump into problems like this, where it turns out to be a bug in their code. For a specific example, see C++ Issues, below. Assuming, however, that your test program’s code is OK, it’s time to investigate environmental issues. See Vary Your Environment, below. If your test program fails with a different error… If your test program fails with a different error, look at the test program’s code to confirm that it’s correct, and that it accurately reflects the code you’re trying to run in your IDE. Vary Your Environment If your test program fails with the same error as you’re seeing in your IDE, and you are sure that the code is correct, it’s time to look for environmental factors. I typically do this with the steps described in the next sections, which are listed from most to least complex. These steps only tell you where things are going wrong, not what is going wrong. However, that’s often enough to continue the investigation of your issue. Vary Your Shell Try running your commands in a different shell. macOS’s default shell is zsh. Try running your commands in bash instead: % bash … bash-3.2$ clang -o hello hello.c bash-3.2$ ./hello Hello Cruel World! Or if you’ve switched your shell to bash, try it in zsh. Vary Your User Account Some problems are caused by settings tied to your user account. To investigate whether that’s an issue here: Use System Settings > Users & Groups to create a new user. Log in as that user. Run your test again. Vary Your Mac Some problems are system wide, so you need to test on a different Mac. The easiest way to do that is to set up a virtual machine (VM) and run your test there. Or, if you have a separate physical Mac, run your test on that. Vary Your Site If you’re working for an organisation, they may have installed software on your Mac that causes problems. If you have a Mac at home, try running your test there. It’s also possible that your network is causing problems [1]. If you have a laptop, try taking it to a different location to see if that changes things. [1] I rarely see this when building a simple test program, but it do see it with other stuff, like code signing. C++ Issues If you’re using C++, here’s a simple test you can try: % cat hello.cpp #include <iostream> int main() { std::cout << "Hello Cruel World!\n"; } % clang++ -o hello hello.cpp % ./hello Hello Cruel World! A classic problem with C++ relates to name mangling. Consider this example: % cat hello.c #include <stdio.h> #include "hello-core.h" int main(int argc, char ** argv) { HCSayHello(); return 0; } % cat hello-core.cpp #include "hello-core.h" #include <iostream> extern void HCSayHello() { std::cout << "Hello Cruel World!\n"; } % cat hello-core.h extern void HCSayHello(); % clang -c hello.c % clang++ -c hello-core.cpp % clang++ -o hello hello.o hello-core.o Undefined symbols for architecture x86_64: "_HCSayHello", referenced from: _main in hello.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) The issue here is that C++ generates a mangled name for HCSayHello: % nm hello-core.o | grep HCSayHello 0000000000000000 T __Z10HCSayHellov whereas C uses the non-mangled name: % nm hello.o | grep HCSayHello U _HCSayHello The fix is an appropriate application of extern "C": % cat hello-core.h extern "C" { extern void HCSayHello(); }; Select Your Tools Temporarily Sometimes you want to temporarily run a command from a particular tools package. To continue my earlier example, I currently have Xcode 14.3 installed in the Applications folder and Xcode 15.0b5 in ~/XcodeZone. Xcode 14.3 is the default but I can override that with the DEVELOPER_DIR environment variable: % clang -v Apple clang version 14.0.3 (clang-1403.0.22.14.1) … % DEVELOPER_DIR=~/XcodeZone/Xcode-beta.app/Contents/Developer clang -v Apple clang version 15.0.0 (clang-1500.0.38.1) … Revision History 2025-01-27 Remove the full width characters. These were a workaround for a forums platform bug that’s since been fixed. Made other minor editorial changes. 2023-07-31 First posted.

I am unable to proceed with the Apple Developer program as my identity could not be verified through the Apple Developer app. However, I have all the necessary company documentation ready and can provide it upon request. This is an urgent matter, as I need this account to deploy our company’s app as soon as possible. Please advise on the next steps or required information/documentation to resolve this issue.

I am using Xcode 15.2. I am loading a URL in a WKWebView, but a hand cursor appears above the web view. Scrolling up and down does not work. I tried adjusting the scroll bounds and isUserInteractionEnabled, but the hand cursor is still visible. How can I fix this?

After updating from Xcode 15.4 to Xcode 16.2, I am unable to build my project. I would greatly appreciate any advice or guidance on how to resolve this issue. Thank you in advance for your help and guidance.

I am Developer of SMCB ANAND Application, my Apple Developer Program membership had been expired in September 2024. I observed that expired in November 2024. Since that time i couldn't able to renew Apple Developer Program membership. I went through Apple Developer app for renew the membership but still i couldn't renew it Kindly provide a solution for the same
