LLVM Linker Crash on ARM64 with bfloat16 Symbols (Xcode 17.0.0)
We're encountering a critical linker crash in Xcode 17.0.0 (clang-1700.4.4.1) on macOS 15.1.0 (Darwin 25.1.0) with Apple Silicon M3 Max when linking a pybind11 C++ extension against the MLX framework (v0.30.1). The linker consistently crashes with LLVM ERROR: No way to correctly truncate anything but float to bfloat during the linking phase, even though our code uses only integer types (int64, uint32) for BPE tokenization and never directly references bfloat16 types.
Error Details:
[100%] Linking CXX shared module _metal_trainer.cpython-312-darwin.so
LLVM ERROR: No way to correctly truncate anything but float to bfloat
clang++: error: unable to execute command: Abort trap: 6
clang++: error: linker command failed due to signal (use -v to see invocation)
Reproduction:
Install MLX framework: pip install mlx (any version with bfloat16 support)
Create a minimal pybind11 extension that links against MLX:
Compiler: AppleClang 17.0.0.17000404
Target: arm64-apple-darwin25.1.0
Flags: -std=c++17 -O2 -march=native
Link against: libmlx.dylib (contains bfloat16 symbols)
Run: cmake .. && make
Linker crashes during final linking phase
Root Cause: The LLVM ARM64 backend in Xcode 17.0.0 has a code generation bug when processing bfloat16 truncation operations during link-time. The crash occurs when the linker processes bfloat16 symbols from libmlx.dylib, regardless of whether the application code uses them. The error originates from LLVM's type legalization pass attempting to truncate bfloat16 values, but the ARM64 backend lacks a valid code path for this operation.
Workarounds Attempted (all failed):
Disabling LTO: INTERPROCEDURAL_OPTIMIZATION FALSE
Linker flags: -Wl,-no_compact_unwind, -fno-lto
Runtime symbol resolution: -undefined dynamic_lookup
Compiler optimizations: Changed from -O3 to -O2
Impact: This blocks any C++ extension development that links against libraries containing bfloat16 symbols on Xcode 17.0.0. The issue does not occur on Xcode 16.x.
Linker Crash Dump Location: /var/folders/gn/7_g6wy1j66b8z3lkywyrbsx00000gn/T/linker-crash-*
Expected Behavior: Linker should successfully link the extension, or at minimum, gracefully handle bfloat16 symbols without crashing.
Temporary Solution: Downgrade to Xcode 16.x or use Python-only implementations until this is fixed in a future Xcode release.

Is there a way to check or be notified for new Xcode beta versions?
The only way I know is to manually keep checking the available betas web page to see if anything new is available (while also manually comparing it to the installed version).
Or am I missing something?
Hello ,
after last update in Xcode, now the Apple Intelligence (Chat GPT) appears only what it was “changed” but don’t apply on code!
Any solution?

I'm developing in Objective C with Xcode on a Mac exclusively to run on Mac and all of a sudden when I try to run I get the message:
"a build only device cannot be used to run this target". If I go to the destination folder, the newly built app is there and runs from Finder, I just can't get it to run from within Xcode, which is inconvenient for testing.
What setting am I missing or has changed? Up to now I could build and run with no problem.

Since upgrading my iPhone 13 Pro Max to iOS 26, apps have become nearly impossible to debug. The recent update to iOS 26.1 has made this even worse.
Going from app start to a fully rendered & responding screen takes <1 second on a Debug build when no debugger is attached, but with the debugger attached I get these times (measured manually with a stopwatch):
First render:
<1 second without debugger
5 seconds on USB debugger
30 seconds on wireless debugger
Data loaded from webserver and UI responding:
<1 second without debugger
19 seconds on USB debugger
5 minutes on wireless debugger!
Doing an online speed test reports 55 Mbps for the phone and 60 Mbps on the MacBook, so I doubt it's my WiFi.
Having a debugger attached used to make minimal difference on iOS 18, but the performance has tanked completely since the last major release. What happened?
Hello,
While setting up Xcode Cloud using Bitbucket, I encountered an issue with Source Control and providing access to the repository.
The problem most likely stems from the fact that Bitbucket has updated its policy, and the use of app passwords is no longer available (at least for new ones). However, in Xcode → Settings → Source Control, the login flow still requires an app password, which makes it impossible to authenticate using the new API tokens. Attempting to authenticate via SSH also does not resolve the issue.
After connecting to GitHub, I also tried to connect through the web version, but I'm getting the same message: "Bitbucket Cloud installation was incomplete." I received this same message when I first tried to connect through Xcode.
This problem does not occur when connecting to GitHub.
I would appreciate receiving feedback from the Apple team on this issue.

Hey!
I am writing type formatting scripts in Python for lldb, as described in https://lldb.llvm.org/use/variable.html#python-scripting. I'm trying to pass an environment variable to lldb from Xcode to determine the path to the scripts in the project root, so the project is not bound to some predetermined path. I am having trouble doing this in Xcode.
What I have tried:
lldbinit file
Create a .lldbinit file in $(SRCROOT) with the following content: platform shell echo $SRCROOT.
Set the path to the .lldbinit file in Edit Scheme... > Info > LLDB Init File ($(SRCROOT)/.lldbinit).
Set the SRCROOT environment variable to $(SRCROOT) in Edit Scheme... > Arguments > Environment Variables.
entry-point breakpoint
Add a breakpoint to the entry-point of the application.
Set the Automatically continue after evaluating actions option.
Add the action platform shell $(SRCROOT) or platform shell $SRCROOT.
Set the SRCROOT environment variable to $(SRCROOT) in Edit Scheme... > Arguments > Environment Variables.
What I expect to happen: The first line of the debug console is a path pointing to $(SRCROOT)
What actually happens: No path is output
Is this functionality available in Xcode Version 26.0.1 (17A400)?
Thanks in advance,
Barnabas
I have a small, simple iOS project that doesn't use a lot of memory or libraries or anything.
If I open my iOS project in XCode and run it on the iPhone 17 simulator, my memory consumption (as seen in Activity Monitor) goes into the yellow zone.
Granted, I have some other apps open (Safari, Mail, Messages, the usual stuff that people run) but nothing especially demanding. Without XCode and the Simulator running, my memory consumption is only around 25% on the Activity Monitor graph.
Is this expected behavior with Tahoe and iOS 26?
I was able to work on my project without running out of RAM on this same computer for the past 4 years no problem. Now it seems I have a problem.
in my xcode project, i created a new package by going through File > New > Package, just like they said in https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages
I have a package, but the problem is, whenever I made any changes in the package's source code, it never showed in the main project. I can import the package just fine, but the package does not show anything. no added apis, functions, nothing.
Im using Xcode 26.0.1
When xcode is installed on a mobile phone, the first run always fails. The second run usually works normally.The certificate signatures have been checked and all are normal。This problem will also occur if you stop the running xcode and then run it again。please help me.

I updated my project (a Swift-based Screen Saver) from Xcode 14 to 15, and while the project works fine, I'm seeing a bunch of warnings during the link phase like this:
ld: warning: reexported library with install name
'/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/SpeechSynthesis.framework/Versions/A/SpeechSynthesis'

'/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/SpeechSynthesis.framework/Versions/A/SpeechSynthesis.tbd'
couldn't be matched with any parent library and will be linked directly
Am I doing something wrong?
Can I safely suppress these warnings?
In the official explanation, "deployment targets" refers to "the OS range supported by this version of Xcode for uploading apps to App Store Connect." On the Xcode Support page (https://developer.apple.com/support/xcode/), I can find the deployment targets supported by each Xcode version.
My question is: can I use a newer version of Xcode to build an IPA with an older deployment target that isn’t listed? For example, can I use Xcode 26 to build an iOS 12 IPA (just build, not debug)?
In my opinion, since the new SDKs still contain many old macros restricted to earlier iOS versions, it should be possible, but I’m not sure if that’s correct.
Thanks.
On devices and simulators with iOS 26.1, the animation does not work correctly (the initial and final screens are distorted). I use open class func transition(with view: UIView, duration: TimeInterval, options: UIView.AnimationOptions = [], animations: (() -> Void)?, completion: ((Bool) -> Void)? = nil)
with options: .transitionFlipFromRight
Opened a FB already (FB20928652) but wanted to check here if anybody has seen similar or has better workarounds.
xcresulttool merge appears to crash immediately after launch in Xcode 26.1 (and in 26.2b1).
It does so regardless of any inputs passed in; the crash appears to be during argument parsing before any other logic is run, so it's not contingent on inputs.
Working example from 26.0.1 (passing in arbitrary strings for a minimum-reproducible-case, so we expect to see an error message) :
% /Applications/Xcode-26.0.1.app/Contents/Developer/usr/bin/xcresulttool merge --output-path a b c
Error: File or directory doesn't exist at path: b.
Usage: xcresulttool <subcommand>
See 'xcresulttool --help' for more information.
The same example crashes in 26.1:
/Applications/Xcode-26.1.0.app/Contents/Developer/usr/bin/xcresulttool merge --output-path a b c
zsh: trace trap /Applications/Xcode-26.1.0.app/Contents/Developer/usr/bin/xcresulttool merge
Again, this does crash in real use cases as well, the arbitrary strings are just for quick reproduction.
The stack trace appears to be during argument parsing (which from a quick look, did indeed change between 26.0.1 and 26.1). On 26.1+, garbage data seemingly gets passed to AbsolutePath.init.
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1

frame #6: 0x00000001804d5d54 dyld`start + 7184
The only workaround we've found is to keep using 26.0.1's copy of xcresulttool, though that's obviously not ideal.
Since a few days, I'm trying to fetch our private SPM repo hosted on Azure via Xcode but without success. Actually they now accept only ssh key RSA-SHA2-256 or RSA-SHA2-512.
So I created a new SSH key, but it seems the problem persists when I try to fetch spm repo or git clone via xcode:
"You’re using ssh-rsa that is about to be deprecated and your request has been blocked intentionally. Any SSH session using SSH-RSA is subject to brown out (failure during random time periods). Please use rsa-sha2-256 or rsa-sha2-512 instead. For more details see aka.ms/ado-ssh-rsa-deprecation. remote: ERROR_SSH_UNSUPPORTED_CIPHER (7) (-20)"
Even so I'm choosing the good new ssh key, it seems Xcode is sending wrong information about the new generated ssh key.
Anyone is experiencing the same here?
Hi there,
When I deploy my app to the iPhone for testing, I get the following error:
Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the
Please ensure that the certificates used to sign your app have not expired. If this issue persists, please attach an IPA of your app when sending a report to Apple.
executable is no longer valid.)
My account was mistakenly deactivated by Apple last month. After appealing, Apple restored it at the end of last month. Currently, my Apple Developer account seems to be working fine.
Today, I recreated the developer certificate and identifier, added the account in XCode, everything seemed fine, and I clicked the XCode button (Start the active scheme). The build was successful, but I got the error:
Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the executable is no longer valid.)
Both my certificate and identifier were created just a few hours ago and show no issues.
Before my account was deactivated, everything was working fine.
I used a regular non-Apple developer account in XCode and performed the same steps, and it worked fine.
I looked at relevant posts on the forum and tried the suggestions, but none of them solved my problem.
Hi,
I am reaching out to seek assistance with a persistent code signing issue that is preventing our team from installing our iOS app, "Scoopz" (https://apps.apple.com/us/app/scoopz-real-life-real-video/id6449206831) on physical devices. We suspect there may be an issue with our Apple Developer account, as we have exhausted all standard troubleshooting steps without success. Below, I’ve provided details about the issue, the error logs, and the steps we’ve taken.
Issue Description:
When attempting to install the app on an iPhone using Xcode, we encounter the following error:
Unable to Install “Scoopz: Debug”
Domain: IXUserPresentableErrorDomain
Code: 14
Recovery Suggestion: Failed to verify code signature of /[REDACTED_PATH]/OurApp.app : 0xe8008018 (The identity used to sign the executable is no longer valid.)
The app builds successfully to the iOS Simulator and can be released to the App Store without issues, but it fails to debug on physical devices.
Steps Taken:
Our team has attempted the following troubleshooting steps without resolving the issue:
Verified that our Apple Developer account is active and our team membership is valid.
Checked certificates in Keychain Access and the Apple Developer Portal, ensuring they are not expired or revoked. We created and installed new Apple Development certificates.
Confirmed that the provisioning profile includes the target device’s UDID, is associated with a valid certificate, and is not expired. We regenerated and reinstalled the profile. We tried both xcode managed and manually installed profiles.
Cleaned the Xcode build folder, deleted the app from the device, and rebuilt the project.
Despite these efforts, the issue persists across our entire development team, leading us to believe there may be a problem with our Apple Developer account or its associated certificates/profiles.
Request for Assistance:
We kindly request your help to:
Investigate any potential issues with our Apple Developer account that could be causing this code signing error.
Verify the status of our certificates and provisioning profiles on Apple’s servers.
Provide guidance on any additional steps or configurations needed to resolve the error.
If necessary, suggest how we can escalate this issue for further investigation.

Hello
I have developed a standalone app for watchOS - trying my best to use best practices and floowing the (limited)documentation. But here I am, unable to distribute - or even Validate - my apps archive in Xcode.
As far as I can tell, bundle_id's are correct. It has an iOS wrapper (set up by New Project), Skip install has been tried in every combination.
I'm at a loss.
I'm sure there is some simple setting or workflow that I am missing, but I've been at it for days. Yes. Days.
Has anyone recently created and successfully distributed a standalone watch app that could help me troubleshoot?
I would be extremely appreciative. My kids would too. They miss their dad (just one 5 more minutes, I think I got it!)(I didn't get it)
Thank you

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!
