Hi, I'm testing out Xcode 16 beta and I have a couple of questions: Is Swift Assist only available on Sequoia? I see that predictive code completion is per https://www.apple.com/newsroom/2024/06/apple-empowers-developers-and-fuels-innovation-with-new-tools-and-resources/, but I tried the beta on Sonoma and I'm not seeing it Regarding Swift Assist - I understand that code is only used to process requests and never stored on servers, and Apple will not use it to train machine learning models. However, my company's security team may still decide that using Swift Assist is too much of a risk. How can we disable it across multiple developer machines? Thank you!

We have a script that builds several Swift Packages using xcodebuild. Since Xcode 16.3, xcodebuild crashes when invoked on a Swift Package, with the following error xcodebuild -list Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -list Resolve Package Graph ** INTERNAL ERROR: Unable to load workspace '/Users/glaurent/Developer/livesight-universalsdk/SDKs/Modules/CommonObjC' ** Uncaught Exception: -[Swift.__SwiftDeferredNSArray intersectsSet:]: unrecognized selector sent to instance 0x600002593e00 Stack: 0 __exceptionPreprocess (in CoreFoundation) 1 objc_exception_throw (in libobjc.A.dylib) 2 -[NSObject(NSObject) __retain_OA] (in CoreFoundation) 3 ___forwarding___ (in CoreFoundation) 4 _CF_forwarding_prep_0 (in CoreFoundation) 5 -[DVTCoreDevice(DVTCoreDeviceIDE) deviceSupportsBuildable:buildParameters:error:] (in IDEFoundation) 6 -[DVTCoreDevice(DVTCoreDeviceIDE) supportedArchitecturesForBuildableContext:buildParameters:error:] (in IDEFoundation) 7 _IDERunDestinationsForBuildableUsingDeviceWithBuildParameters (in IDEFoundation) 8 -[IDERunDestinationManager runDestinationsForScheme:schemeCommands:executionEnvironment:eligibleOnly:genericOnly:architectureVisibility:] (in IDEFoundation) 9 IDESchemeDetermineAvailableRunDestinations (in IDEFoundation) 10 -[IDEScheme _actuallyInvalidateAvailableRunDestinations] (in IDEFoundation) 11 addSchemeAndMakeActiveIfNecessary #1 (result:error:) in IDESwiftPackage.generateScheme(with:buildable:additionalBuildables:unsetRunnable:makeActive:orderHint:) (in IDESwiftPackageCore) 12 IDESwiftPackage.generateScheme(with:buildable:additionalBuildables:unsetRunnable:makeActive:orderHint:) (in IDESwiftPackageCore) 13 IDESwiftPackage.generateSchemes(_:isRootPackage:) (in IDESwiftPackageCore) 14 IDESwiftPackage.update(from:graphHasErrors:delegate:) (in IDESwiftPackageCore) 15 specialized IDESPMWorkspaceDelegate.rootPackagesDidUpdate(packages:graphHasErrors:modelGraphSynchronizerToken:) (in IDESwiftPackageCore) 16 closure #1 in IDESPMWorkspaceDelegate.packageGraphDidFinishAction(_:duration:result:) (in IDESwiftPackageCore) 17 partial apply for closure #1 in IDESPMWorkspaceDelegate.disableWorkspaceContentSynchronization(during:) (in IDESwiftPackageCore) 18 <deduplicated_symbol> (in DVTFoundation) 19 <deduplicated_symbol> (in DVTFoundation) 20 thunk for @escaping @callee_guaranteed () -> () (in DVTFoundation) 21 __58-[DVTModelObjectGraph performBlockCoalescingModelChanges:]_block_invoke (in DVTFoundation) 22 -[DVTModelGraphTransactionScope performTransaction:] (in DVTFoundation) 23 -[DVTModelObjectGraph performBlockCoalescingModelChanges:] (in DVTFoundation) 24 DVTModelObjectGraph.performBlockCoalescingModelChanges<A>(_:) (in DVTFoundation) 25 IDESPMWorkspaceDelegate.disableWorkspaceContentSynchronization(during:) (in IDESwiftPackageCore) 26 IDESPMWorkspaceDelegate.packageGraphDidFinishAction(_:duration:result:) (in IDESwiftPackageCore) 27 <deduplicated_symbol> (in IDESwiftPackageCore) 28 SPMWorkspace.packageGraphActionFinished(_:) (in SwiftPM) 29 closure #2 in closure #3 in SPMWorkspace.processPackageGraphActionsInBackgroundIfNeeded(canProcessPackageGraphActions:) (in SwiftPM) 30 partial apply for closure #1 in SPMSDKPackageContainer.loadManifest() (in SwiftPM) 31 specialized thunk for @escaping @isolated(any) @callee_guaranteed @async () -> (@out A) (in SwiftPM) 32 partial apply for closure #1 in SPMSDKPackageContainer.loadManifest() (in SwiftPM) 33 completeTaskWithClosure(swift::AsyncContext*, swift::SwiftError*) (in libswift_Concurrency.dylib) This error happens regardless of the command passed to xcodebuild.

Trying to submit a build to TF from Xcode 26 via Xcode Cloud (both for iOS and macOS). The operation fails with this message: Missing app icon. Include a large app icon as a 1024 by 1024 pixel PNG for the 'Any Appearance' image well in the asset catalog of apps built for iOS or iPadOS. Without this icon, apps can't be submitted for review. For details, visit: https://developer.apple.com/documentation/xcode/configuring-your-app-icon. If you’ve added an icon made with Icon Composer, visit https://developer.apple.com/app-store-connect/release-notes/ for details about known issues. I thought it's because Icon Composer icons may not be supported yet, but then that last sentence is confusing me. Does this mean that TF just won't support Xcode 26 uploads yet, or does it accept them and I need to provide legacy icons for my build?

I just wanted to say thank you to the team that added coding assistance (Chat-GPT) to Xcode. I'm just learning SwiftUI and I love how it made suggestions to improve my app and shows me what it does and explains why it does what it does.

I can't find Rosetta Simulators in Xcode 26 Beta, even when I select "Show all destinations."

I would like to use devicectl to take a picture of my iPhone screen on iOS 17. So far I have successfully performed, Launching and exiting the app I created. Reboot the iPhone connected via USB etc.... I used to use libimobiledevice, but when I bought a new iPhone with iOS17, I can't do it anymore.

Hi, in our Xcode project we have a Tooling package, which defines build tool plugins for generating compile time safe constants for our localization strings as well as assets using swiftgen. This is working very well in Xcode 16, but fails in Xcode 26 beta 1 and beta 2 as well. The failure is specifically: unsupported configuration: the aggregate target 'Localization' has package dependencies, but targets that build for different platforms depend on it. I've reduced this to a minimal sample project, which you can find here.. To reproduce: Open the Repro workspace, that is attached in Xcode. Try to build TestyPackage. You'll see the error. I've filed this bug during WWDC week, but no feedback yet and no solution in Xcode 26 beta 2. Here's the feedback number, in case you have this too and want to file a duplicate: FB17934050. Does anyone else have this issue and perhaps a solution?

Since first beta of iOS 26 I've created a workflow where I can deploy to TestFlight the builds compiled using the iOS 26 SDK, and it has worked fine until yesterday when I started receiving this error: Unsupported SDK or Xcode version. Your app was built with an SDK or version of Xcode that isn’t supported. Although you can use beta versions of SDKs and Xcode to build and upload apps to App Store Connect, you need to use the latest Release Candidates (RC) for SDKs and Xcode to submit the app. For details on currently supported SDKs and versions of Xcode, visit: https://developer.apple.com/news/releases. I haven't changed anything in the workflow so I suspect it's a bug on Apple side? Or am I missing something? It is set to use "Latest Beta or Release" for both Xcode and macOS, archive and deploy to TestFlight Internal Testing. Thank you!

We are getting following error in xcode cloud "The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes" We are using following env to create a build. Xcode: 14.2 Macos: Ventura 13.2.1 We didn't face any issue in Ventura 13.2.0 and we are seeing this issue in our first build using ventura 13.2.1. The difference I see between successful and failure build, I don't see "Discovering Swift tasks after 'Compiling { list of swift file " in a failed build. I see compiling { list of swift file } and end of the compilation, the build is failing.

Problem I’m trying to implement Sign in with Apple in my application. However, when my app redirects to the Apple authorization page at: https://appleid.apple.com/auth/authorize I get an invalid_client error with no further explanation. Settings I followed this article closely: [https://developer.okta.com/blog/2019/06/04/what-the-heck-is-sign-in-with-apple#generate-the-client-secret] Steps I have completed: Created an App ID and a Service ID on Apple Developer Portal. Enabled “Sign in with Apple” for both the App ID and the Service ID. Added my domain and callback URL to the Service ID configuration. (I'm using ngrok to proxy my localhost during development.) Linked an existing private key with “Sign in with Apple” capability. My identifiers: Service ID is used as client_id Team ID is taken from the top right of the Apple Developer dashboard Key ID is from the private key associated with the App Environment My backend is built with Laravel, and I'm using the [SocialiteProvider/Apple][https://socialiteproviders.com/Apple/#installation-basic-usage] library to handle the OAuth flow. I followed the recommended method to generate a client secret (JWT) for each request, using this blog post: [https://bannister.me/blog/generating-a-client-secret-for-sign-in-with-apple-on-each-request] My .env configuration looks like this: APPLE_CLIENT_ID=com.service.paxton.stockApp APPLE_TEAM_ID=25729642DK APPLE_KEY_ID=JFP9Q53ZCY APPLE_PRIVATE_KEY=storage/AppleDev-AuthKey_JFP9Q53ZCY.p8 JWT Generation I also tested generating the JWT using the Ruby script from the Okta article: [https://developer.okta.com/blog/2019/06/04/what-the-heck-is-sign-in-with-apple#generate-the-client-secret] Here is the script I used: require 'jwt' key_file = './storage/AppleDev-AuthKey_JFP9Q53ZCY.p8' team_id = '25729642DK' client_id = 'com.service.paxton.stockObserve' key_id = 'JFP9Q53ZCY' ecdsa_key = OpenSSL::PKey::EC.new IO.read key_file headers = { 'kid' => key_id } claims = { 'iss' => team_id, 'iat' => Time.now.to_i, 'exp' => Time.now.to_i + 86400*180, 'aud' => 'https://appleid.apple.com', 'sub' => client_id, } token = JWT.encode claims, ecdsa_key, 'ES256', headers puts token This JWT validates correctly. I’ve also used Apple’s public key to verify the signature, and it passed. I verified the JWT header and payload format using this helpful article: [https://fluffy.es/how-to-solve-invalid_client-error-in-sign-in-with-apple/] Third-Party Testing To eliminate mistakes in my setup, I even tried a third-party tool featured in this YouTube video: [https://youtu.be/8v01TaX1EJA?si=0jOBGBVk0R0zbmdo] Unfortunately, the result was the same — invalid_client. Question I’ve double-checked everything I can think of: keys, claims, domain whitelist, identifiers. I even verified the JWT independently. If anyone (especially someone from Apple) can help identify the missing piece, I would be truly grateful.

Hi everyone, Starting today, my Xcode Cloud CI workflow can no longer successfully build iOS/macOS/visionOS targets. The Archive step does not report any errors, but the xcodebuild command hangs indefinitely and eventually fails with the following message: The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes. My iOS and macOS targets can still be built, but the build time has increased by 2-3x compared to before. That's interesting. After I removed the visionOS target, the iOS target also failed to build. Additionally, since today, I’ve noticed a significant increase in network-related errors in Xcode Cloud. There have been multiple failures to download dependencies from Homebrew or GitHub. I have confirmed that CI versions which previously built successfully are now failing, while running the same build commands locally works fine. Based on these observations, I suspect there may be an issue with the Xcode Cloud environment itself. Has anyone else encountered similar problems? Any suggestions or updates would be appreciated! Thanks!

Our developer account was granted the com.apple.developer.mail-client by Apple ages ago, which we use for one of our apps. At the time, this entitlement was granted through a special "entitlements" drop-down on the profile creation page. In fact, the entitlement is still available to us in this manner: Unfortunately, applying the entitlement directly to the profile no longer works through the App Store Connect API. Which is a bummer because we periodically use the API to update our development and ad hoc profiles with new UDIDs. I was eventually able to get Apple to migrate the entitlement to a capability that we can instead apply to the app IDs in our account. Great! However, for some reason the "Default Mail App" capability (on the "Edit your App ID Configuration" screen) shows does NOT apply to Ad hoc profiles: Note that "Ad hoc" is missing. This means we still need to update the Ad hoc profile for the app in question manually through the Apple developer portal. This has to be a bug. It makes no sense that this specific capability doesn't apply to Ad hoc profiles. Other capabilities don't have this issue. e.g.: Another strange thing is that on the profile page for the ad hoc profile under "Enabled Capabilities" it shows "Default Mail App" (see screenshot above) but the capability/entitlement is missing from the downloaded profile unless I add it via the drop down menu on the profile page. How do I get Apple to fix this? Multiple support tickets submitted via our developer account have gone unanswered. (It took months just to get the entitlement partially migrated in the first place.)

Any idea what this message means? I assume it's coming from CloudKit, but the application seems to store and retrieve data properly.

After updating my system to macOS Tahoe 26.1 and Xcode 26.1, all breakpoints in my project fail to work. When I run the application in Debug mode, any enabled breakpoint (blue) immediately becomes disabled (grayed out) the moment the app launches. The application runs, but the debugger never stops. This issue occurs in any location, including in the application's init() method, which should always be hit. This behavior suggests that the LLDB debugger is failing to attach to the process at launch or is being instructed not to enable breakpoints. System Configuration: Mac Model: MacBook Pro 14" (2021), Apple M1 Pro macOS Version: Tahoe 26.1 Xcode Version: 26.1 Project Type: SwiftUI App for macOS Troubleshooting Steps Performed (All Unsuccessful): We have performed an extensive series of troubleshooting steps to resolve the issue, none of which have worked. These steps include: Basic Project Cleaning: Cleaned the build folder (Product > Clean Build Folder). Deleted the entire DerivedData directory. Deleted the project's xcuserdata folder. Xcode & System Procedures: Restarted Xcode multiple times. Rebooted the Mac multiple times. Reinstalled Xcode Command Line Tools using xcode-select --install. Reset the Xcode path using sudo xcode-select --reset and sudo xcode-select -s /Applications/Xcode.app/Contents/Developer. Forced an update of the system's shared cache with xcrun simctl runtime dyld_shared_cache update --all. Project Build Settings Verification (for Debug configuration): Build Configuration: Verified that the "Run" scheme is set to Debug. Optimization Level: Confirmed it is set to No Optimization [-O0]. Debug Information Format: Confirmed it is set to DWARF with dSYM File. Strip Swift Symbols: Confirmed it is set to No. (This was a new setting noticed after the Xcode update). Enable Hardened Runtime: Attempted setting this to both Yes and No. The issue persists in both cases. Validate Workspace: Confirmed it is set to Yes. Code Signing: Verified that "Automatically manage signing" is enabled with a valid team. Manually deleted and re-created the "Apple Development" certificates via Xcode's Accounts settings. Direct LLDB Testing: Created a ~/.lldbinit file. Using breakpoint list, confirmed that LLDB starts with "No breakpoints currently set," indicating that Xcode is likely not passing the breakpoints to the debugger. Using settings set target.process.stop-on-entry true, confirmed that the app still does not stop on entry, suggesting the debugger is failing to attach to the process at all. Conclusion: Given that all standard and advanced troubleshooting steps have failed, and the issue started immediately after updating both macOS and Xcode to a non-public release (Tahoe 26.1 / Xcode 26.1), this appears to be a regression or a bug in the new development environment. The failure of stop-on-entry strongly suggests a fundamental issue with the debugger attachment process on this specific OS and Xcode combination.

ChatGPT in Xcode 26.1 is super slow for me, anyone else? The response returns quickly but the preview window takes a few seconds per line. What it used to do in a few seconds on 26.0 now takes tens of minutes. Anyone else running into this and have suggestions? I'm using the minimal setting on a fast internet connection.

Right now, I am trying the tutorial for SwiftUI from the Apple Developer Program inside of Xcode, but I encountered a problem. Inside of the selectable canvas mode in Xcode, I wanted to command-control-click the element (in this case, a text) to bring up the editing popover and select "Show SwiftUI Inspector." For some reason, on the popover menu, the only option was "Embed." I only wanted the menu point Show SwiftUI Inspector, and I also tried the shortcut Ctrl+Option, but nothing worked. Now is there another method to get to this menu? Or can you help me with that? Noah

I am writing to report multiple issues encountered after updating to Xcode 26 Beta, which have significantly impacted my project's compilation and functionality. My project can run normally in Xcode16.3 version, Below are the specific problems, along with the steps I took to address them and the subsequent errors that arose: Symbol Not Found Error for _NSUserActivityTypeBrowsingWeb After updating to Xcode 26 Beta, my project failed to build with the error: "Symbol not found: _NSUserActivityTypeBrowsingWeb." To resolve this, I removed the MobileCoreServices framework from the Build Settings, as it appeared to be related. However, this led to a new error, indicating that this change introduced further complications. Clang++ Error: No Such File or Directory 'OpenGLES' Following the resolution of the first issue, I encountered a new error: "iOS clang++: error: no such file or directory: 'OpenGLES'." To address this, I added the OpenGLES.framework to the Build Phases. While this resolved the clang++ error, it triggered additional errors, suggesting that the underlying issue persists or new dependencies are conflicting. Recurring XIB File Compilation Errors My project uses XIB files, and every time I attempt to compile and run, Xcode reports errors related to different XIB files. Notably, when I open the reported XIB file, no errors are displayed within the Interface Builder. After saving or inspecting the file, the compilation error temporarily disappears, only for another XIB file to trigger the same issue in the next build. This creates a repetitive cycle. I have confirmed this is not a caching issue, as I clean the build cache (Product &gt; Clean Build Folder) before each run. If I skip cleaning the cache, the OpenGLES-related error (Issue 2) reappears, indicating potential interactions between these problems. These issues have made development with Xcode 26 Beta extremely challenging, as each attempted fix seems to introduce new errors, and the XIB issue creates a persistent loop. My setup includes: Xcode Version: 26.0 beta 2 (17A5241o) macOS Version:15.4.1 (24E263)

I can't access my approved and verified Apple Developer account on the web and my certificates were revoked. When I sign in with the correct email and password, I am redirected to a page asking me to enroll in the Developer Program, even though I successfully enrolled and was approved months ago. Everything with Apple Developer account had been working fine for months, and the iOS App Store app confirms that my Apple Developer Program membership subscription is still active. And if I click "Enroll Today," it says my Apple ID is already associated with an "account holder of a membership." Additionally, my macOS app certificates have been revoked without any email or explanation, and I cannot create new ones due to this issue. Also I can access my developer account via iOS and macOS apps normally, but I can't access it on the web to create new certificates. This I urgent and time sensitive for me, can someone please help?

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 am trying to fix a bug in my iOS app that is dependent upon date and time. Is there any way to set the actual time on the iOS Simulator to a specific date and time? I know that you can set one for the status bar, but that doesn't affect the actual date and time that is reported by the system to apps.
