xattr -c not removing com.apple.FinderInfo attribute from Xcode files
Hi all, reposting this from here: https://unix.stackexchange.com/questions/789849/xattr-c-not-removing-com-apple-finderinfo-attribute I came to this problem because my Xcode project was failing to build due to the error "resource fork, Finder information, or similar detritus not allowed" (was trying the solutions on this post). Basically, running xattr -cr . in the terminal on my project directory removes all extended attributes except com.apple.FinderInfo, which stays on all .xcodeproj and .xcworkspace files. I've tried everything under the sun, from sudo to xattr -d to dot_clean to tar to rsync and nothing works. Is this just an immortal attribute that can never be removed? I'm truly at a loss here, this is for my senior thesis project.

swift package with arm64e
I use spm manage swift package, now i want my macos app support arm64e,so i add arm64e in Build Srtting -> Architectures. but i got error Could not find module 'SwiftyJSON' for target 'arm64e-apple-macos'; found: arm64-apple-macos, x86_64-apple-macos Apparently, if no limit in Package.swift, SPM will only compile versions for x86 and ARM64 architectures by default. now, how should I configure SPM to compile the arm64e version? thanks

Xcode 16.3 Compile fails
After updating to 16.3, my project now fails to compile with the diagnostic: "Command SwiftCompile failed with a nonzero exit code". This is a SwiftUI document project with two local packages, the second of which is a rather large one with 112 SwiftUI files. It is this second package that is failing. There are no issues when compiling with 16.2. Without diagnostics I'm having a bit of difficulty in determining the cause. My thought is to regress the commits unit 16.3 gives a success, or shows issues. Although I'm not catching a similar issue in the forums, I'm seeing other problems with 16.3. Has anyone else had such build failure isolated to 16.3? Any advice on other ways to approach this problem? Thanks in advance

Icon Composer and Xcode building time
Hi everyone, I’ve run into a strange issue while building my app with Xcode 26 beta 6 (targeting iOS 26). When I include an app icon created using Icon Composer, the build time jumps to over 5 minutes. During this time, I noticed that a utility called AssetCatalogSimulatorAgent is consuming a significant amount of CPU. If I remove the Icon Composer-generated icon from my target, the build completes in about 40 seconds. This behavior is consistent across multiple builds. Has anyone else experienced this? Is there a known workaround or optimization for icons created with Icon Composer? I’d love to keep using the new icon format, but the build time is becoming a real bottleneck. Thanks in advance!

Warning: Error creating LLDB target at path. the specified architecture 'arm64-*-*' is not compatible with 'x86_64-apple-ios13.2.0-simulator'
Every time my app runs in the simulator I see this error: Warning: Error creating LLDB target at path '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app'- using an empty LLDB target which can cause slow memory reads from remote devices: the specified architecture 'arm64--' is not compatible with 'x86_64-apple-ios13.2.0-simulator' in '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app/Babylist' What is this? I'm on an M1, no build issues. It makes me think the simulator is running under rosetta with x68_64. But I didn't choose to do that. Mac OS Ventura. Xcode 14 RC.

How do I use IOUserSCSIPeripheralDeviceType00?
I am having similar problems to this guy on Stack Overflow over a year ago: https://stackoverflow.com/questions/77627852/functions-of-iouserscsiperipheraldevicetype00-class-in-scsiperipheralsdriverkit There are also a few questions on this forum about this object, none of which have answers. I can get my driver to match and instantiate, but nobody calls my UserDetermineDeviceCharacteristics (which does nothing, just returns kIOReturnSuccess) I can attempt to call UserSuspendServices(), UserResumeServices() or UserReportMediumBlockSize() and all of them return kIOReturnUnsupported. It doesn't matter if I've unmounted the disk or not. Is the custom driver supposed to be instantiated beside the kernel's IOSCSIPeripheralDeviceType00, or should it replace it? What should its IOProviderClass be? What should its IOClass be - IOUserService, or something else? see FB19678139 and FB19677920

After updating to Xcode 16.3, getting the error - Symbol not found: ___cxa_current_primary_exception
It didn't happen with Xcode 16.2 that I used before, but after updating to 16.3, when I build the app, the following error is output to the console and the app doesn't run. dyld[2150]: Symbol not found: ___cxa_current_primary_exception Referenced from: <6B00A4F2-B208-3FDB-BA38-B7095AF0034A> /private/var/containers/Bundle/Application/B590DB18-9C66-4C9E-8330-104943419E60/Mubeat DEV.app/Mubeat DEV.debug.dylib Expected in: <7F51CB08-A0CA-386E-BB62-4B8BFB0CED9F> /usr/lib/libc++.1.dylib Symbol not found: ___cxa_current_primary_exception Referenced from: <6B00A4F2-B208-3FDB-BA38-B7095AF0034A> /private/var/containers/Bundle/Application/B590DB18-9C66-4C9E-8330-104943419E60/Mubeat DEV.app/Mubeat DEV.debug.dylib Expected in: <7F51CB08-A0CA-386E-BB62-4B8BFB0CED9F> /usr/lib/libc++.1.dylib dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/usr/lib/libRPAC.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib After looking for another solution, I found a way to remove the -Objc option in Other Linker Flags, but this method only works on iOS 18.4 and doesn't work on other versions. Is there another solution?

Orphaned 9GB Simulator Runtime in /System/Library/AssetsV2 - Cannot Delete (SIP protected)
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.

Project xcodeproj file can no longer by iCloud Sync
Following an unexpected error message while working in Xcode, the project file xcodeproj is no longer synced in iCloud Drive. The Finder shows a cloud icon with a ! and an error message : (NSFileProviderErrorDomain error -2005.) If the local file is zipped, and unzipped elsewhere on iCloud Drive, then the unzipped file can still not be iCloud Synced. Restoring the file from a Time Machine archive does not solve the issue. Apple Care Support finds that iCloud Drive is working fine except for this xcodeproj file and says the issue is Xcode related.

Xcode 14.0.1 does not have support for iPhone 13 Mini in interface builder
With Xcode 14, the device selection on the bottom of the storyboard canvas has changed, and the iPhone 12 and 13 mini screens are no longer there, as well as there only being one model of iPad. Is there a way to add more devices to this section? I have simulators installed for these devices, and this is the way I've been checking compatibility so far, but this is not sustainable. I appreciate any help that you can give me.

iOS simulator triggers lots of "*** quit unexpectedly" alerts
Everytime when iOS simulator is launched I het a lot of repeated "*** quit unexpectedly" alerts. Where "***" is a mix of "managedappdistributiond","healthappd", and "findmylocated" Even after the simulator is launched I still het random "*** quit unexpectedly" alerts. Very annoying because the alerts deactivates the active window This is on an MacBook Pro M3 Max,, Xcode 15.2, Sonoma 14.2.1, it also happens with Xcode 15.1 A co developer (MacBook Pro M1 Max,Xcode 15.2, Sonoma 14.2.1) does not have the issue Any idea how I can prevent this from happening? Update Every mentioned service crash happens in libswiftCore.dylib at 0x1929f3938 assertionFailure(:_:file:line:flags:) + 248

Xcode shows alert about unknown com.apple.quicklook.preview extension point when running on Apple Vision Pro Simulator
I have an iOS app with a QuickLook extension. I also added Apple Vision Pro in the target's General > Supported Destinations section. About one year ago, I was able to run the app on iPhone, iPad and Apple Vision Pro Simulators. Today I tried running it again on Apple Vision Pro with Xcode 26.0.1, but Xcode shows this error: Try again later. Appex bundle at ~/Library/Developer/CoreSimulator/Devices/F6B3CCA8-82FA-485F-A306-CF85FF589096/data/Library/Caches/com.apple.mobile.installd.staging/temp.PWLT59/extracted/problem.app/PlugIns/problemQuickLook.appex with id org.example.problem.problemQuickLook specifies a value (com.apple.quicklook.preview) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. I tried again later a couple times, even after running Clean Build Folder Immediately, without any change. I can reproduce this with a fresh Xcode project to which I add a Quick Look Preview Extension and Apple Vision Pro as a supported destination. The error doesn't happen when running on Apple Vision Pro (Designed for iPad) or iPad Pro 13-inch (M4) destinations. What is the problem? I created FB20448815.

Device with Number Already exists on this Team
I've created a new project in Xcode. I'm running the Xcode 16.4 and MacOS 15.5. I'm trying to run my barebones project on my iPhone 16 (I'm just getting started). I turned on developer mode on my iPhone and went through the whole process. But in the Signing & Capabilities of my project under status I see two errors... There is a problem with the request entity A device with number 'XXXX8801C' already exists on this team. Provisioning profile "iOS Team Provisioning Profile: [MyBundleID]" doesn't include the currently selected device "My iPhone" (identifier XXXX8801C). I noticed in the devices on the developer portal that my device is showing as "Processing." I feel ike it's stuck. But I can't figure out how to clear it all out and try again. It's been 24 hours since this error came up. I've tried to clear trusted computers on the iPhone. I've deleted the "Derived Data" folder. I've removed my developer account from Xcode and added it again. I've restarted both my Mac and my iPhone multiple times. I've noticed it asked to authorize my computer twice. When I clear the authorized computers and then plug the phone back in it asks twice again. So I'm not sure if this is the issue? No idea why it asks twice but I'm only ever able to respond to the second request as the first request gets blocked in the UI by the second requests if that makes sense? I'm also not able to turn off developer mode on my iPhone. The switch isn't there as the docs state it should be. So again, I feel like this is the phone and the developer portal stuck causing the problem. Note: I saw someone else had encountered this problem and I replied to it and boosted it. But it looks like it was posted in 2017? Hence this new post.
