How to delete iOS simulator runtimes?
There are multiple iOS simulator runtimes located at /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime which I don't need. I tried the following approaches to delete them but not working. Xcode > Settings > Components > Delete (It can delete some but not all of them) xcrun simctl runtime list (It doesn't show the old runtimes) sudo rm (Operation not permitted) sudo rm -rf cc1f035290d244fca4f74d9d243fcd02d2876c27.asset Password: rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData/096-69246-684.dmg: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/Info.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/version.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset: Operation not permitted I have two questions: Why "xcrun simctl runtime list" is unable to list some old runtimes? How to delete them?

Incremental build not working on Mac mini CI (Xcode 26) — always full rebuild
Hi everyone, We run our CI builds on a Mac mini. On my local MacBook, incremental builds work properly and build times are fast, but on CI it looks like Xcode rebuilds everything from scratch every time, and the build is about 6 minutes slower than local. In Xcode 26, “compilation caching” became available. My understanding was that if DerivedData is preserved between CI runs, compilation caching / incremental builds should reduce build time. So I tried specifying the DerivedData path as an absolute path in our xcodebuild command to reuse it across builds. However, it still seems to do a full rebuild every time and the build time didn’t improve. Has anyone seen a similar issue with incremental builds on CI (Mac mini) with Xcode 26? Any advice on what to check or how to configure CI so incremental builds / caching actually work would be greatly appreciated. Thanks!

Code Coverage Not Generated in Xcode 26.1 Despite Successful Test Runs
We’re facing an issue with Xcode 26.1 where code coverage is not being generated. All our test cases run and pass successfully, but the .xccovreport / .xccovarchive files are never produced. Code coverage is enabled in the scheme, and this setup used to work correctly in earlier Xcode versions. We are trying to determine whether this is a configuration issue on our end or a possible Xcode 26.1 bug. Is anyone else experiencing the same problem with code coverage in Xcode 26.1? Any insights or workarounds would be appreciated.

Metal toolchain compilation error after migration to MacOS 26 and XCode 26.1
Hello. I migrated yesterday two machines from OS15 to OS26 (same Ram; M1Max chip). On the first one, a MBP, everything is allright, and my old Metal projects can compile and run, even with MacOS12 as a destination. On the second computer (MacStudio) I got a compile "error: cannot execute tool 'metal' due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain". I spent hours on many forums and tried all proposed solutions and still get the same error. Any idea? Thanks

Help: Compiled Timeline Issues
I have developed a fun living diorama world using Reality Composer Pro and XCode. Everything is as it should be, and it looks/works great ... until it does not. If I seem to make any change to any of the 10 timelines that I am using (all on the same scene, no nested scenes), running the app in simulator, device, and via testflight throws errors around compiled timelines, leading to the black screen of death. Every time I clean and run, the timelines in questions might change. Its very frustrating and impossible to track down. Heres are some examples. AssetLoadRequest failed because asset failed to load '/ (3661553931319769725 Timeline (RealityFileAsset)URL/file:///var/containers/Bundle/Application/F4408256-6014-4264-9E4B-F74AEF0EDE53/SantasVillage.app/RealityKitContent_RealityKitContent.bundle/RealityKitContent.reality/Timeline_779.compiledtimeline)' (failed to register asset) Asset / (13631856135570808851 AnimationLibraryAsset (RealityFileAsset)URL/file:///var/containers/Bundle/Application/F4408256-6014-4264-9E4B-F74AEF0EDE53/SantasVillage.app/RealityKitContent_RealityKitContent.bundle/RealityKitContent.reality/AnimationLibraryAsset_1.compiledanimationlibraryasset) failure: failed to register asset Asset 10430065658338454790 AnimationScene (RealityFileAsset)URL/file:///var/containers/Bundle/Application/F4408256-6014-4264-9E4B-F74AEF0EDE53/SantasVillage.app/RealityKitContent_RealityKitContent.bundle/RealityKitContent.reality/AnimationScene_14.compiledanimationscene failure: failed to register asset I went with recommended fixes of closing RCP > Clean Build Folder > Delete Derrived Date (multiple ways) > Re-Open Xcode > Reset Package Cache > Re-Open RCP via XCode > Make a Change > Save > Clean Build Folder Again > Run. Sometimes it works. Most times it does not. I then found my own little work-around, but its not always working as is literally costing me days of wasted time messing around with this. I will DISABLE all timelines, do the above clean method, rerun with no timelines, and it resolves. Then, turn on timelines ONE BY ONE and run until I get another error. Then, rebuild that timeline and nothing else. This is not sustainable. There must be some better way to do this? Or, perhaps I am doing something wrong? Please help if you can.

Xcode 26 cannot run app on simulator, as well as unit test
Hi, When running unit test or app on simulator, it got process crashed mostly of the case, it works fine on the same project, like in Xcode 16.x.

SPM Traits not working correctly with multiple targets in same Xcode workspace (App + App Clip)
Hi, I've just migrated to Swift Tools 6.2 and package traits, and I'm encountering an issue when using traits with multiple targets in the same Xcode workspace. Setup: Main iOS app target App Clip target Both consume the same local packages (e.g., UIComponents) What I'm trying to achieve: Main app imports packages without the COMPACT_BUILD trait App Clip imports packages with the COMPACT_BUILD trait enabled Package configuration (simplified): // UIComponents/Package.swift let package = Package( name: "UIComponents", platforms: [.iOS(.v18)], traits: [ .trait(name: "COMPACT_BUILD", description: "Minimal build for App Clips"), ], // ... targets: [ .target( name: "UIComponents", dependencies: [...], swiftSettings: [ .define("COMPACT_BUILD", .when(traits: ["COMPACT_BUILD"])), ] ), ] ) In the code: #if COMPACT_BUILD // Excluded from App Clip #endif The consumer packages: Main app's package imports without trait: .package(path: "../UIComponents") App Clip's package imports with trait: .package(path: "../UIComponents", traits: ["COMPACT_BUILD"]) The problem: When building the main app target, the COMPACT_BUILD compiler condition is unexpectedly active — even though the main app's dependency chain never enables that trait. It seems like the trait enabled by the App Clip target is "leaking" into the main app build. I confirmed this by adding #error("COMPACT_BUILD is active") — it triggers when building the main app, which shouldn't happen. If I disable the App Clip target from the build scheme, the main app builds correctly with COMPACT_BUILD not defined. I am also able to build the App Clip separately. Environment: Xcode 26.2 swift-tools-version: 6.2 iOS 26.2 Questions: Is this expected behavior with Xcode's SPM integration? Are traits resolved workspace-wide rather than per-target? Is there a workaround to have different trait configurations for different targets consuming the same package? Or do I need to fall back to separate package targets (e.g., UIComponents and UIComponentsCompact) to achieve this? Any guidance would be appreciated. Thanks!

Xcode 26.0 Share Extension crashes with NSInternalInconsistencyException on iOS 26.0
Issue : When creating a new project in Xcode 26.0 and adding a Share Extension target without modifying any code, the app crashes upon displaying the extension screen with the following error: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The layout constraints still need update after sending -updateConstraints to <_UINavigationBarTitleControl: 0x105b9cc00; frame = (0 0; 0 0); layer = <CALayer: 0x10b834270>>. _UINavigationBarTitleControl or one of its superclasses may have overridden -updateConstraints without calling super. Or, something may have dirtied layout constraints in the middle of updating them. Both are programming errors.' Environment : Xcode 26.0 iOS 26.0 (physical device) Note: This issue does not occur when running on iOS 18.3.1 (physical device). Temporary Workaround : Adding the following implementation to the isContentValid method prevents the exception from occurring: Objective-C- (BOOL)isContentValid { // Do validation of contentText and/or NSExtensionContext attachments here if (@available(iOS 26, *)) { self.navigationController.navigationBarHidden = YES; } return YES; } Questions : Is there any alternative way to avoid this exception? Since this crash occurs with the default implementation generated by Xcode, is there any plan to fix it in future updates?

XCTest doesn't return the elements in navigation bar after iOS 26 upgrade
The buttons in the navigation bar are not available in the element tree after iOS 26 upgrade of the test phones. The same IPA version, the same XCode version, but different trees on different phones. There is no way to automate UI testing for these missing buttons. # ios 18 NavigationBar, 0x108e0c3c0, {{0.0, 47.0}, {390.0, 44.0}}, identifier: 'Profile' Button, 0x108e0c500, {{8.0, 47.0}, {43.0, 44.0}}, identifier: 'UserProfileSceneViewController_profile_back_button', label: 'chevronLeftIcon' StaticText, 0x108e0c640, {{169.3, 58.0}, {51.3, 22.0}}, label: 'Profile' Button, 0x108e0c780, {{339.0, 47.0}, {43.0, 44.0}}, identifier: 'UserProfileSceneViewController_settings_bar_button', label: 'Settings' # ios 26 NavigationBar, 0x13d63c8c0, {{0.0, 47.0}, {428.0, 54.0}}, identifier: 'Profile' StaticText, 0x13d63ca00, {{188.3, 58.0}, {51.3, 22.0}}, label: 'Profile'

Build keeps failing with PhaseScriptExecution error
I have a Unity AR project that I want to build for iOS. The build in Unity succeeds just fine, but when it opens in XCode, whatever I do, it keeps showing this error in GameAssembly: "Command PhaseScriptExecution failed with a nonzero exit code". This error also doesn't open when choosing "Reveal in Log". I have added the IL2CPP package in the Unity version, deleted and reentered scenes and no issue on Unity's side. On XCode I signed in with my developer account, tried deleting derived data, made a clean build and still the issue persists.

XCode will not allow access to Code Commit
I'm really sick of Apple and their BS kickbacks they get from github and the other source control outfits restricting what source control packages we can use inside of XCode. We have used Code Commit with AWS for YEARS! We are not switching but apple's Xcode will not allow us to add it as an account. We used to be able to use it, but Apple took away the GIT account setup so now you have to use one of their kickback outfits. This is complete BS Apple. Even AWS realized how important Code Commit is and made it available to everyone again and pledged full support going forward. How about you get off your collective sixes and do the same. I'd like an explanation on why you took away the one feature that allows us to use what works for us.

Reminders app developer tutorial console warning: ... The existing content view does not support the new configuration
Hi, I am working through the https://developer.apple.com/tutorials/app-dev-training/editing-reminders The app runs as described, but in the Xcode 26.1.1 console, I get numerous warnings that say: Warning: You are setting a new content configuration to a cell that has an existing content configuration, but the existing content view does not support the new configuration. This means the existing content view must be replaced with a new content view created from the new configuration, instead of updating the existing content view directly, which is expensive. Use separate registrations or reuse identifiers for different types of cells to avoid this. Make a symbolic breakpoint at UIContentConfigurationAlertForReplacedContentView to catch this in the debugger. Does this app need to be updated for Xcode 26, or are there settings in Xcode 26 that I need to make to get rid of these warnings? Thanks

Augmented Reality app unable to load the image from the camera
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]. Failed on timestamp: 870.413247, Last known timestamp: 865.350198, Delta: 5.063049, System timestamp: 870.415781, Delta between system and frame: 0.002534. } and then again the pose issues several times. 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.
