Hello,
I'm trying to build XNU with KASAN support. However I get error:
clang: error: unsupported option '-fsanitize=kernel-hwaddress' for target 'arm64e-apple-darwin23.2.0'
If I try to compile a non-kernel C code with -fsanitize=hwaddress, I get the same target error.
But Apple ships HWASan kernels with KDK, which shows there is a clang which is capable of compiling hwasan code for arm64e.
How can we compile hwasan sanitized code ourselves? Is it a private toolchain or released somewhere?
Xcode Sanitizers and Runtime Issues
RSS for tagXcode Runtime Issues are reports of programming errors found at run time. Issues can be found by variety of tools, including Address Sanitizer (ASan), Main Thread Checker (MTC), Thread Sanitizer (TSan), and Undefined Behavior Sanitizer (UBSan).

I didn't find any errors in my program, and Xcode didn't report any errors in the program code, but when I ran it, it inexplicably reported an error:
Command CompileAssetCatalog failed with a nonzero exit code
What should I do?
Hi!
I noticed that when I use the simple Textfield in SwiftUI it generates unexpected error:
-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:] perform input operation requires a valid sessionID
Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem.
If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable.
Here is the code example to repoduce the error:
import SwiftUI
struct ContentView: View {
@State private var firstName = ""
var body: some View {
TextField("First name", text: $firstName)
}
}
How it could be fixed ? Is it one of the bugs that came along with iOS 17 ?
Thank you!

I'm writing here because I'm out of ideas now, I allow my iOS app to be used on macOS and previously I was able to launch my app via XCode and perform debugging but suddenly I'm not able to launch my app anymore (I updated my OS (12.6) and my XCode (14.0.1) in the meantime). When I start it I see the icon but then it immediately crashes with following error in the output
AddressSanitizer: CHECK failed: sanitizer_mac.cpp:1231 "((ret_value)) <= (((1ULL << 36)))" ...
AddressSanitizer: CHECK failed: sanitizer_mac.cpp:1231 "((ret_value)) <= (((1ULL << 36)))" ...
(lldb)
I can't even put a breakpoint anywhere as my code doesn't even get executed. I tried a test project and it works there but my project doesn't start up even though it works perfectly fine on iOS/ tvOS and on iPads. How can I fix this error or what's exactly the problem?
Dear Experts,
When I try to use Address Sanitizer on my iOS app, it reports "attempting free on address which was not malloc()-ed" whenever a C++ exception is caught.
If first saw it inside Apple's libFontParser and filed FB13271831, but I now see it in my own code. The Address Sanitizer stack trace always starts like this:
#1 0x215766ae8 in __cxa_decrement_exception_refcount+0x40 (/usr/lib/libc++abi.dylib:arm64e+0x13ae8)
Having looked up __cxa_decrement_exception_refcount in the C++ ABI docs, my guess is that the C++ runtime is creating and destroying the exception objects in some way that Address Sanitizer doesn't properly understand, causing it to think that they are being freed without having been allocated by malloc.
This is only really a problem because it does not seem possible to continue after ASan has reported this error; the app is terminated.
Question: is there a way to tell Address Sanitiser to ignore errors in this function? And/or, is there a way to continue after the error?
Thanks.
I face this problem on Xcode 15, and on so many forums talk about old version of Xcode. Can someone help me on it please. Thank you a lot
I am using Xcode 14.3 and when Issue that says "Could not find bundle inside /Library/Developer/CommandLineTools under scntool". I searched this up and tried reinstalling CommandLineTools, reinstalling xcode, and reseting xcode.
Here are screenshots of the issue: https://docs.google.com/document/d/1H6HsoZoJhISMo-5cXG-kN0hat6jftcujL1iYK2TRkeA/edit
And here is the code: https://github.com/EnderRobber101/Xcode
Is there a solution? Please inform me of the solution. Thank you for reading.
Hi!
I am getting the next warning returned when the textfield is focused. Xcode version: 14.3.1. Should I ignore it ?

Hi, I am working on the apple pie project trying to figure out why this line of code is outputting an error. all of my connections are correct and I have double checked them and the game file is correct as well. how can I remove this error and continue the project? [
