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?

My native language is not English, so apologies if I say anything wrong. (The screenshot is for illustration only.) I’m currently using Xcode 16.4 (16F6). Inside Xcode, macOS 15.5 is shown as built-in, and the Predictive Code Completion Model is already installed. But even though I already installed Xcode before, and even ran the simulator components once, in the past few days whenever I open a project or run the simulator, this “Select the components you want to get started with” screen suddenly pops up again. At the bottom it even shows “installed,” but I can’t do anything else except click Install. When I click it, it says “Installing system components,” but it finishes very quickly. I just want to know why this keeps happening. The only things I did recently were updating to macOS 26 and installing Xcode Command Line Tools 26. Could these be related? Do I need to worry about this? Thanks!

I'm experiencing a persistent iOS Simulator app installation failure when running automated tests using Appium/XCUITest. The error occurs consistently across different simulator configurations and appears to be related to metadata handling during app installation.

Hello, I'm trying to use Xcode's ARKit Session replay functionality. I have a capture I made using Reality Composer and when trying to use it with Xcode's replay functionality the installation and debugging process seems stalled forever. I've gotten it to work once so I know the capture file is functional but I have never gotten it to work a second time, even though I didn't change any settings. No amount of restarting Xcode, the Mac, or the iPhone seem to work. I have also tried cleaning build folders, reinstalling the app, and clearing DerivedData. I can confirm from the Xcode logs that the app installs correctly but the app never launches. If I unselect the checkbox for "ARKit Replay Data", the app launches and debugs nearly instantly. I have tried letting it "attach" for up to 10 minutes to no avail.

My Mac Catalyst app fails with a "MissingEntitlement" error when accessing keychain/secure storage, while the same code works perfectly on iOS. I have tested this extensively on macOS using Visual Studio Code on a MacBook, trying both automatic and manual provisioning approaches - both result in the same MissingEntitlement error during keychain operations. Error Message: "An error occurred during OTP verification: Error adding record: MissingEntitlement" Environment : Platform: Mac Catalyst (.NET 9.0) Issue: Keychain access fails on macOS, works on iOS Development: Using .NET MAUI What I've Tried : Entitlements Configuration Added keychain-access-groups to Entitlements.plist: xml <key>keychain-access-groups</key> <array> <string>$(AppIdentifierPrefix)com.example.myapp</string> </array> Project Signing Setup (.csproj configuration) : <PropertyGroup Condition="'$(TargetFramework)'=='net9.0-maccatalyst'"> <EnableCodeSigning>true</EnableCodeSigning> <ProvisioningType>manual</ProvisioningType> <DevelopmentTeam>TEAM_ID</DevelopmentTeam> <CodesignKey>Apple Development: Name (XXXXXXXXXX)</CodesignKey> <ProvisioningProfile>PROVISIONING_PROFILE_UUID</ProvisioningProfile> <CodesignEntitlements>Platforms/MacCatalyst/Entitlements.plist</CodesignEntitlements> <UseHardenedRuntime>true</UseHardenedRuntime> </PropertyGroup> Has anyone encountered similar issues with Mac Catalyst keychain access?

Does anyone know how to solve this? Suddenly X-code stopped allowing me to build on my iPhone. Works fine in simulato.

I have a major problem with team membership and Xcode. I work in a company, where my apple account was added to the development team with app manager role. I can see that on the apple portal, everything seems fine there. I have been also provided with the provisioning profile for the project and signing certificate of the company. However, when I log into Xcode the team does not show up anywhere. I am able to build the app, but cannot distribute to TestFlight (or anywhere else). When I use manual signing to choose the signing certificate it shows the "unknown team" message next to it. When I check my account in xcode it also only shows my personal team and does not allow to pick any other one (doesn't show any other one). When I click the "+" button on my xcode account to add a certificate an error pops up: "You already have active certificate or a pending request". I do have a pending request to enroll into apple developers program, but everyone says you don't need one if you are added to the team, you can just operate as a team member. Finally, when trying to upload to TestFlight, the following error is displayed: "No team for account ***" I have tried deleting and re-adding all the certificates. I have tried logging in and out of Xcode, I have tried deleting and re-adding my account in Xcode. I have tried reloading everything. My account was deleted and re-added to developers team. Nothing worked. I don't know the source of the issue, nor does my employer. I am new to ios development and this is my first project. Please help!

When I compile my Xcode project using the xcodebuild command, I observe long incremental build durations. For example, compiling a new, empty project in Xcode only takes around one second. The same project takes 7 seconds to compile using the xcodebuild command. I've noticed that xcodebuild hangs at the "GatherProvisioningInputs" phase. Steps to Reproduce: Create a new Xcode project (iOS app template) Build the project in Xcode with timing summary enabled Build the same project from the command line with the following command: time xcodebuild -destination 'platform=iOS Simulator,name=iPhone 15 Pro,OS=latest' I would appreciate any insights or suggestions on how to improve the build times when using the xcodebuild command. Thank you in advance for your help!

Hi everyone, have any of you tried running an app from Xcode 16.x (during development, running on device) on one of the iPhone 17 models? I'd like to know whether it still works or if someone would need to update to Xcode 26 for that to work.

Hi everyone, After updating my Mac and Xcode to 26, I’m running into a consistent crash whenever I try to launch an app from Xcode. Environment: Mac: Apple Silicon M3 macOS: 26.0 (25A354) Xcode: 26.0.1 (17A400) Issue: When I press Run on any project (including new, empty projects), Xcode immediately crashes. This started only after updating to the latest macOS and Xcode. Crash details: The crash log shows: Application Specific Signatures: ___localError Thread 0 crashed inside -[IDEScheme _executionOperationForSchemeOperationParameters:...] from IDEFoundation/IDEKit. I also noticed background threads calling DVTPortal (developer portal requests) right before the crash. What I’ve tried so far: Cleared DerivedData, ModuleCache.noindex, and Xcode caches. Signed out/in of my Apple ID in Xcode. Recreated project schemes. Verified provisioning profiles. Reinstalled Xcode 26. Unfortunately, the crash still happens. Question: Is this a known issue with Xcode 26 on Apple Silicon (M3)? Has anyone seen a workaround? Any guidance would be greatly appreciated — I can’t currently launch apps in Xcode at all. Thanks!

Hey there Just updated to Xcode 26 on mac OS Sequoia (MBP M1 Max 32GB, 2021, so you know, still pretty decent and capable). Xcode is super slow on building, but also on editing. There is a lag between what I type and what is displayed. Am I the only one experiencing this? Is there something I should look into?

I am using the latest version of Xcode 16, and I have created a GPX file in my project. However, I am unable to see or select the file to simulate the GPS location. I have attempted to uninstall and reinstall Xcode completely, but the issue persists. Has anyone encountered a similar problem? How can I resolve this? Thank you.

My app hangs and I get this error when using an inspector view on macos tahoe. Changing to a different type of view resolves the issue. The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window. <SwiftUI.AppKitWindow: 0x8897e0000> 0xb4d8 (46296) {{1004, 182}, {1254, 948}} en Future marking as needing Update Constraints in Window might be ignored.

After updating from Xcode 16 to the new Xcode 26 beta 3, running my iOS app becomes slow to the point of unusable. It builds and installs fine, but when running with the console, it lags about 20-50x compared to building and running with Xcode 16. I wanted to try our Xcode 26 to preview my new app icon made in icon composer but now I don't think it's worth the hassle. When running via simulator, the same performance issues. Anybody also struggling with slow on-device testing speed? I am on Sequoia 15.5.

When I try to build my project with Xcode 26.1 beta (17B5025f) it freezes a lot. The steps are as follows: Open my project with the aforementioned Xcode Start a build of one of my schemes Open a browser or any other app above the Xcode window Try to present the Xcode window on the foreground Result: Xcode freezes I cleared the Derived Data and it still happens

Hi everyone, I’m a student developer currently building a watchOS app that uses HealthKit and HKWorkoutSession to estimate core body temperature from real-time heart rate data. The app runs well in the simulator, but testing on a physical Apple Watch has been extremely difficult. Each time I try to run the app from Xcode (Version 16.3), the build gets stuck on: “Copying shared cache symbols from MyWatchName (0% completed)” Sometimes it just stops stating connection failure. However, more often no errors are shown, but the sync never finishes. I’ve tried the following without success: Restarting the watch, iPhone, and Xcode Switching networks (Wi-Fi and hotspot) USB wired pairing Resetting developer settings and trust prompts Deleting derived data Rebuilding the project This is especially limiting for a real-time health tracking app where I need to monitor HKLiveWorkoutBuilder data while the screen sleeps — which can’t be tested effectively in the simulator.
