I have a MacMini M2 machine running Sequoia 15.1 OS. On this machine, I am running a Virtual Machine, utilizing the Virtualization.Framework, with the same OS version, 15.1. Logging into my account in the System Settings is successful. Next, I need to add my account in Xcode 16.1. While the initial login is successful, Xcode immediately displays the following error: Decoding Error. There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format. As a result, I cannot see any account information, teams, etc. A very similar bug has been reported at this issue - https://developer.apple.com/forums/thread/759877, but there has been no progress or updates there. Is there any chance to fix this and get it working?

I just submitted a feedback for this (FB9662125) but in the spirit of “share and enjoy”… The cool new Generate Info.plist File feature in Xcode 13 crashes if you try to put an NSLocationTemporaryUsageDescriptionDictionary in your Info.plist file. Here’s a simple repro scenario: Create a minimal iOS app (no Core Data, no tests) Go to target settings → Info tab → Custom iOS Target Properties Click the (+) button on any row to begin inserting a new row Select Privacy - Location Temporary Usage Description Dictionary Click somewhere else or press Return to commit the selection Xcode crashes immediately More generally, it seems that Xcode crashes any time it tries to regenerate your Info.plist file if it contains an NSLocationTemporaryUsageDescriptionDictionary, even if (for example) you manually pasted that dictionary into the file earlier. In that case, merely tapping the (+) button in step 3 above is enough to crash it.

The Foundation Models Framework stopped working after Xcode failed to download the "Predictive Code Completion Model". What happened was on macOS Tahoe 26.0: Downloaded and installed Xcode 26 Beta (17A5241e) Worked with Foundation Models framework. Everything worked fine. ✅ Opened Xcode 16.4 This triggers the downloading of Predictive Code Completion Model which then fails. Go back into Xcode 26 Beta, Foundation Models framework no longer works. ❌ Error: "Failed to find asset: com.apple.gm.safety_deny.input.code_intelligence.base.generic - no asset" What I've tried or checked: Reinstalling Xcode 26 Beta Uninstalling both Xcodes and only installing Xcode 26 Beta Checked available space on drive (over 300 GB free) Restarted Mac Restarted Xcode 26 Changed wifi networks Turned on VPN Deleted the Library > Developer > Xcode folder and reinstalled Xcode 26 Feedback Report FB18208139: Can't download Predictive Code Completion Model - Xcode 26 Screenshots

I am experiencing an issue where my Mac's speakers will crackle and pop when running an app on the Simulator or even when previewing SwiftUI with Live Preview. I am using a 16" MacBook Pro (i9) and I'm running Xcode 12.2 on Big Sur (11.0.1). Killing coreaudiod temporarily fixes the problem however this is not much of a solution. Is anyone else having this problem?

I Keep getting this error if I try to enroll in the developer program, why is this? Please tell me how to fix this of why this is happening!

I am unable to download the iOS 26.1 Simulator Runtime through Xcode 26.1 on macOS 26.1 (Build 25B78). Issue Details: When attempting to download via Xcode Settings → Platforms, the download fails with error code 41 (DVTDownloadableErrorDomain) and error code 60 (MADownloadCannotConnectToHost) The error message states: "Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({RequestedBuild = 23B80;})" I receive HTTP 403 Forbidden when accessing mesu.apple.com/assets/ Steps Attempted: Downloaded via Xcode Settings → Component → iOS 26.1 Simulator Tried command line: xcodebuild -downloadPlatform iOS Searched https://developer.apple.com/download/all/ - iOS 26.1 Simulator Runtime not listed Tested with different networks (home WiFi, VPN, mobile hotspot) Disabled proxy settings Flushed DNS cache All attempts result in the same error. Important Notes: Xcode 26.1 shows iOS Simulator SDK 26.1 (Build 23B77) is available However, Xcode attempts to download Build 23B80, which appears unavailable I experienced a similar issue previously with Xcode 16.4 requesting iOS 18.4 Simulator Runtime, which was also unavailable for download Impact: Without the iOS 26.1 Simulator Runtime, I cannot develop or test iOS applications. macOS 26.1 requires Xcode 26.1, which in turn requires iOS 26.1 runtime, leaving me unable to perform any iOS development work. Questions: Is iOS 26.1 Simulator Runtime (Build 23B80) officially released? Is there a direct download link available? Should Xcode 26.1 be requesting Build 23B77 instead of 23B80? Is there any account restriction preventing me from downloading newer simulator runtimes? System Information: macOS: 26.1 (Build 25B78) Xcode: 26.1 (Build 17B55) Error description: Download failed.

I have an app on the App Store for many years enabling users to post text into clouds in augmented reality. Yet last week abruptly upon installing the app on the iPhone the screen started going totally dark and a list of little comprehensible logs came up of the kind: ARSCNCompositor <0x300ad0e00>: ARSCNCompositor (0, 0) initialization failed. Matting is not set up properly. many times, then RWorldTrackingTechnique <0x106235180>: Unable to update pose [PredictorFailure] for timestamp 870.392108 ARWorldTrackingTechnique <0x106235180>: Unable to predict pose [1] for timestamp 870.392108 again several times and then: ARWorldTrackingTechnique <0x106235180>: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop].

I hoped the new beta version would have solved the issue, but it was not the case. Unfortunately I do not know if that depends on the beta version or some other issue, given the app may be not installed on the Mac simulator.

Hi there, I successfully created an AppIntent for our app, and when I had it in the same target as our main app it showed up fine in the shortcuts app. Then I realized that many of the new System Control widgets introduced in iOS 18 (e.g. lockscreen, control center) live in the widget extension target, but they also need to reference that same AppIntent. So to fix this, I thought I'd migrate out the code into it's own SPM package that both the WidgetExtension and the Main App processes can reference. However, after doing that and rebuilding, the intent no longer shows up in the Shortcuts app. Furthermore, my AppShortcutsProvider class now has this error when trying to define the list of appShortcuts: App Intent <name> should be in the same target as AppShortcutsProvider Is this intended, and if so, how do we reference the same AppIntent across multiple targets?

Trying to post a question about packages on this forum, I keep cueing the message: 'This post contains sensitive language. Please revise it in order to continue.' There is nothing in my query that is remotely ‘sensitive’. I don’t know what to do next. Thanks in advance for any advice. Regards, Lar

I've just downloaded "Additional Tools for Xcode 13" after today's release, and installed "Network Link Conditioner.prefPane" on my macOS Big Sur 11.6 (20G165). But it just don't work. Every time I try to open it an error appeared. Dose the tool only support macOS Monterey which Xcode 13.0 (13A233) dose not support? BTW, the workaround for me is using the tool in "Additional Tools for Xcode 12.5"...

Hello. In the Xcode 15 we were using this command in the terminal to run our tests on the Rosetta Simulator: xcodebuild -workspace CoreLibraries.xcworkspace -scheme CoreLibraries -destination 'platform=iOS Simulator,name=iPhone 15,arch=x86_64' test` In the Xcode 16 the same command doesn't work anymore. It produces the error: xcodebuild: error: Unable to find a device matching the provided destination specifier: { platform:iOS Simulator, arch:x86_64, OS:latest, name:iPhone 16 } Unsupported device specifier option. The device “iPhone 16” does not support the following options: arch Please supply only supported device specifier options. Running test directly from the Xcode UI using iPhone 16 (Rosetta) still works fine. Does anyone know how to modify the xcodebuild command to make it work again?

I've updated my computer to Sequoia 15, Xcode 16 and now no matter what I do, I am unable to work with Swift UI previews. I get this error each time I try to run the preview: Failed to launch app in reasonable time I have done: Uninstall/Re-install Xcode Deleted derived data Deleted the simulator data Used DevCleaner to remove all data related to Xcode Searched all websites about this issue. ( Non shown a good solution ) Write this question on here. If anyone has found a solution, please let me know how you fixed it.

Hi, We use Flat package installers (.pkg based installers) to install our applications on macOS. In macOS 26.1, installation is failing with the error Unable to use PK session due to incompatible packages. Terminating. 2025-11-03 14:22:36+05:30 Admin-3 installer[1160]: Install failed: The Installer could not install the software because there was no software found to install. Same installer package is working on macOS 26. Any help is greatly appreciated.

All is fine in Xcode15, no LLDB errors whatsoever, but in Xcode16 I can't get any variable displayed in the console because of the following error: error: type for self cannot be reconstructed: type for typename "$......." was not found (cached) error: Couldn't realize Swift AST type of self. Hint: using `v` to directly inspect variables and fields may still work. I've checked the output of swift-healthcheck and there are several messages like this: SwiftASTContextForExpressions(module: "ROA", cu: "ROA+ViewLayer.swift")::LoadOneModule() -- Missing Swift module or Clang module found for "UIKit", "imported" via SwiftDWARFImporterDelegate. Hint: Register Swift modules with the linker using -add_ast_path. I added -add_ast_path to the OTHER_LDFLAGS in the faulty module's build settings but no luck. How can I debug my project in Xcode16?

I am experiencing an issue where XCode reverts .xccurrentversion file in my iOS app to the first version whenever xcodebuild is run or whenever XCode is started. This means I can build the app and run tests in XCode if I discard the reversion .xccurrentversion on XCode start. However, testing on CI is impossible because the version the tests rely on are reverted whenever xcodebuild is run. The commands I run to reproduce the issue ❯ git status Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") ❯ git checkout "Path/.xccurrentversion" Updated 1 path from the index ❯ git status nothing to commit, working tree clean ❯ xcodebuild \ -scheme Scheme \ -configuration Configuration \ -sdk iphonesimulator \ -destination 'platform=iOS Simulator,name=iPhone 16 Pro,OS=latest' \ -skipPackagePluginValidation \ -skipMacroValidation \ test > /dev/null # test fails because model version is reverted ❯ git status HEAD detached at pull/249/merge Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: Path/.xccurrentversion no changes added to commit (use "git add" and/or "git commit -a") I have experienced such issue in 16.3 (16E140) and 16.2 (16C5032a). Similar issues/solutions I have found online are the following. But they are either not relevant or do not work in my case. https://stackoverflow.com/questions/17631587/xcode-modifies-current-coredata-model-version-at-every-launch https://github.com/CocoaPods/Xcodeproj/issues/81 Is anyone aware of any solution? Is there a recommended way I can run diagnostics on XCode and file a feedback?
