Xcore 26.2 run on newly installed macOS 15.7.3 (24G419) crashes when attempting to build assets backtrace

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?

Hey, im running a MacBook Pro m2 26.4.1 and Xcode 26.4. I'm trying to upload to App Store Connect and it's getting stuck on "Sending analysis to App Store Connect".... now what's interesting my Mac mini m4. same iOS works fine? Any ideas

Hi everyone, yesterday I updated my macOS and Xcode to the latest versions and today I have the strangest thing: Canvas is always crashing whenever I click it, in any and all my Projects. The full Simulator works just fine; only the Preview Canvas crashes. All the crash reports say it's because of AXRemoteElement-BackgroundFetch, and ChatGPT says it's not because of my code. These are very simple Projects, just for experimentation. Nothing complex, just native code while I follow examples in a SwiftUI book. Anyone else having this issue?

Hello! Every time I attempt to enroll into the program I get hit with one of the following two errors: Unknown Error Please try again. Apple ID Issue The region of the Apple ID that's signed in to Settings or System Preferences is different than the region of the Apple ID with which you signed into the Apple Developer app. Sign in to Settings or System Preferences with an Apple ID that has the same region. I’m very confused by this message because I have never changed the region of my Apple ID - it should be United States. How can I complete my enrollment?

Pulling my hair out here. After upgrading to Xcode Version 26.4.1 (17E202) I've started getting "unable to create tasks to copy stub binary: can't determine architectures of binary: /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Library/Application Support/MessagesApplicationStub/MessagesApplicationStub: Cannot open file handle for file at path: /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Library/Application Support/MessagesApplicationStub/MessagesApplicationStub: The file “MessagesApplicationStub” doesn’t exist." No matter what I do when trying to run the build (worked in previous versions). I've tried fresh install from App Store, direct package download, removing the SDKs, even previous versions and no matter what I get

Hello everyone. I need help! I'm using Xcode solely to create an archive of a mobile application created with WinDev Mobile. When everything is working correctly, I simply retrieve the application's generated version from WinDev Mobile, launch the archive creation process, and add a new version to TestFlight! Then I can test the application on the iPhone. The current problem is that the application crashes, without any error message, in a specific use case. Hoping to get some help with this crash, I had the idea to test the application using Xcode. Once launched, a crash occurs if I follow the same process. There's an error message, which I'll paste below. What does this error mean? How can I relate it to my WinDev Mobile code? Have a good day.

My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...

My Claude Agent component version was 2.1.81, it prompted me for an update the other day from the original release version 2.1.59. But now that I've installed Xcode 26.4.1 it's back to thinking 2.1.59 is the newest version. With every Xcode release it feels like there's a new regression or weird surprise with coding intelligence (26.4 was Claude losing its OAuth token every 8 hours or so). It really feels like this stuff needs more eyes on it. Filed as FB22529202

I have an iOS project based on SwiftUI in which almost all code is organised in Packages. With Xcode 26.2 and 26.3, I can preview all SwiftUI views without issues. With Xcode 26.4, the same previews don't work, in the canvas appears this error message: "Cannot preview in this file. Could not find target description for “TaskListView.swift”". The explanation is: "The list of source files that produce object files did not contain this file to be previewed. Check to make sure it is not excluded using the EXCLUDED_SOURCE_FILE_NAMES build setting." If I add a SwiftUI view to the main project files (not in a package), the preview works as expected. Is it an Xcode 26.4 regression? Or do I need to modify some configuration file?

Dear all, I am not able to transfer a programm to my iPhone 17, i get a certificate issue. Although i followed the general steps. If I was guided to this forum by the german apple support. Before in macOS Sonoma, with iOS 16 and iPhone 8 i have been able building programs for the iPhone. The Simulator has still no issues and works fine. Problem/Error: Certificate installation failed Installing a certificate in the keychain failed (Error Domain=DVTSecErrorDomain Code=-25295 "The specified keychain is not a valid keychain file." UserInfo={NSLocalisedDescription=The specified keychain is not a valid keychain file.}) No profiles for '-.delme2' were found Xcode couldn't find any iOS App Development provisioning profiles matching '-.delme2'. Furthermore, when I try to download a certificate myself via (https://developer.apple.com/account/resources/) I get the error: Unable to find a team with the given Team ID 'XXXXXXXCENSORED' to which you belong. Please contact Apple Developer Program Support. https://developer.apple.com/support In XCode I continue to receive the following information: So no programs can be transferred to my mobile phone. Objective: How do I get the reported errors resolved to transfer programs to my mobile phone?

Since 26.4 beta 3 I've been having errors after a few hours of using Claude Agent. I get an error stating that I am not authed. If I go into Xcode settings, it still shows I am signed into Claude Agent. I have click sign out and then go through the whole auth process again to start using the agent again. This is on two separate computers. Is there anything I can do to stop this behaviour and stay logged in for longer? It worked fine in 26.3.

I have an orphaned asset folder taking up 9.13GB located at: /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime/c0d3fd05106683ba0b3680d4d1afec65f098d700.asset It contains SimulatorRuntimeAsset version 18.5 (Build 22F77). Active Version: My current Xcode setup is using version 26.2 (Build 23C54). I checked the plist files in the directory and found what seems to be the cause of the issue: The "Never Collected" Flag: The Info.plist inside the orphaned asset folder explicitly sets the garbage collection behavior to "NeverCollected": <key>__AssetDefaultGarbageCollectionBehavior</key> <string>NeverCollected</string> The Catalog Mismatch: The master catalog file (com_apple_MobileAsset_iOSSimulatorRuntime.xml) in the parent directory only lists the new version (26.2). Because the old version (18.5) is missing from this XML, Xcode and mobileassetd seem to have lost track of it entirely. What I Have Tried (All Failed) Xcode Components: The version 18.5 does not appear in Settings -> Components, so I cannot delete it via the GUI. Simctl: xcrun simctl list runtimes does not list this version. Running xcrun simctl runtime delete 22F77 fails with: "No runtime disk images or bundles found matching '22F77'." Manual Deletion: sudo rm -rf [path] fails with "Operation not permitted", presumably because /System/Library/AssetsV2 is SIP-protected. Third-party Tools: Apps like DevCleaner do not detect this runtime (likely because they only scan ~/Library or /Library, not /System/Library). Has anyone found a way to force the system (perhaps via mobileassetd or a specific xcrun flag) to re-evaluate this folder and respect a deletion request? I am trying to avoid booting into Recovery Mode just to delete a cache file. Any insights on how AssetsV2 handles these "orphaned" files would be appreciated.

Hi, I’m a paid Apple Developer Program member and I’m seeing an entitlement issuance issue with ShazamKit. ShazamKit is enabled for my App ID (com.tomharris.dnbidfinder) in Certificates, Identifiers & Profiles. However, every iOS Development provisioning profile I generate does not include the entitlement: com.apple.developer.shazamkit verified this by decoding the downloaded .mobileprovision file: security cms -D -i .mobileprovision | /usr/libexec/PlistBuddy -c "Print :Entitlements" /dev/stdin The entitlement dictionary does not contain the ShazamKit key. Because of this: • The signed .app does not contain the Shazam entitlement • SHSession.match(signature) fails on device • I receive ShazamKit runtime error 201 / 212 I’ve already: • Toggled ShazamKit off and back on for the App ID • Created new provisioning profiles • Created a brand new App ID to test • Refreshed profiles in Xcode The portal UI shows ShazamKit as enabled, but the entitlement is not being issued into provisioning profiles. Has anyone experienced this before? Is there an additional approval step required for ShazamKit, or could this be a backend entitlement propagation issue? Thanks.

My Family Controls (Distribution) capability request (C4N7962252) was approved March 15, 2026 for bundle ID com.jedsiegel.unplugtogether. All three Family Controls capabilities are enabled on the App ID. When I generate a provisioning profile (manual or automatic), Xcode reports: "Provisioning profile doesn't match the entitlements file's value for the com.apple.developer.family-controls entitlement." I decoded the profile using security cms -D and found: com.apple.developer.family-controls.app-and-website-usage → present com.apple.developer.family-controls → missing entirely My entitlements file requires com.apple.developer.family-controls with value ["individual"] for AuthorizationCenter. I've tried toggling capabilities off/on, deleting and recreating profiles, switching between automatic and manual signing, and clearing provisioning profile caches. Nothing works because the profile generation itself is not including the entitlement. Team ID: Q4RA4WMD6K Xcode 26.3, targeting iOS 26.2 Has anyone encountered this? Is there a way to get the provisioning system to include this entitlement?

For the last 2 days, the claude agent has stopped working, it's not the issue where you get logged out after 8 hours, I have signed out and back in multiple times, quit xcode, nothing is working, every request just generates the following response: "Your request couldn't be completed."

Several app developers are struggling with the inability to provide a separate app icons that looks nice on older macOS versions while at the same time provide Icon Composer icons that look great on macOS Tahoe 26. An ability to provide separate icons is super important to those who have app icons that follow the curvature of the default icon borders (as the corner rounding radius is different for Sequia and Tahoe). Take a look at this for example: https://github.com/ghostty-org/ghostty/issues/7564#issuecomment-3042061547 Question: Is there a definitive/recommended way to address this issue? How can a developer add a glass icon variant that looks good on Tahoe and provide a bitmap icon for older macOS versions? Some background info: Prior to Xcode 26 beta 4, one could add an App Icon to Assets to be used as app icon for legacy macOS versions (Sequia and older) and use a new Icon Composer icon (placed in the project root) for macOS Tahoe 26. Enabling "Include all app icon assets" under target settings ensured that older macOS versions would use the old app icons while Tahoe the new Icon Composer glass one. Since Xcode beta 4 this technique no longer works. Xcode instead insists on populating Assets.car with Icon Composer generated variants, disregarding the App Icon provided in Assets. Although the App Icon in Assets makes its way to a .incs file in the app bundle's Contents/Resources folder, but that is not used by macOS anymore and is there for some compatibility purposes. The Assets.car file (which matters) only contains the variants generated by Icon Composer and does not contain the png icons provided in the Assets.

I am trying to create a test case in XCTest using the UI Test target. I have a use case where I use a SwiftUI Canvas to draw a network graph; and the user can drag the graph on the Canvas. After the drag, the user may click on a node. The application presents a popup with the information about the network node clicked. SwiftUI provides the information required for the application to translate the location of the tap into the original location prior to the drag; and so the logic behind the popup can determine which node the network graph was tapped by the user. It appears that the distance of the drag operation performed does not match distance that the image actually moved. The drag distance is always larger than the actual distance dragged. I can observe this during the test execution. The arrow starts at the correct spot but then goes further than the object being dragged. I also observe this when I am driving the application. Is there some standard and supported way to determine the distance that the image on the screen was moved given a specific distance of the "thenDragTo:" coordinate?
