I am on M1 (Xcode Version 15.4 (15F31d), MacOS 14.5 (23F79), Simulator IOS 17.4) and as far as I remember printing common usage register was possible. I am not sure why it stopped to work rid, rsi and etc (arg1 arg2 seems like still working).

Hello everyone, I'm encountering an issue while trying to debug a macOS Action Extension. I created a completely fresh project with an Action Extension target. When I select the Action Extension scheme and run it, choosing Finder as the host app (app to launch it in), I receive the following error: Attach failed: Could not attach to pid : “647”. (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.) This is in Console.app: macOSTaskPolicy: (com.apple.debugserver) may not get the task control port of (Finder) (pid: 647): (Finder) is hardened, (Finder) doesn't have get-task-allow, (com.apple.debugserver) is a declared debugger(com.apple.debugserver) is not a declared read-only debugger. I am pretty sure it worked before on my project that I am developing. It stopped working and now it doesn't even work on a fresh new project. Any ideas? I tried cleaning derived data, restarting my mac, nothing helps. As per the documentation it should work normally using the Build & Run button.

i'm trying to get firefox running in 10.7 but the kernel is crashing. i have it working/running/looking great on 10.8 and higher. something is happening in 10.7 that is causing the panic. i need the right kit. someone asked a similar question for 10.11: https://forums.developer.apple.com/forums/thread/108732 but feedback assistant doesn't seem like the right answer. i need this kit to move forward. right now using either the 10.7.0 or 10.7.4 kernel debug kit causes a panic on reboot; something to do with AVX and the fpu. i am hoping APPUL had enough foresight to see this would be an issue (even one year later) for people on newer architectures debugging for older, supported (until 2014) targets: this use-case definitely falls within the parameters.

I am using Xcode 13 on a Macbook Pro (Intel/2019) with macOS Big Sur 11.6 I am building and launching the app on a connecting iPhone X running iOS 15.0, I am also running a UI test suite based on XCUITest while I do that. The app takes extremely long to launch (2+ minutes), then it sits on the splash screen for another 2-3 minutes. Meanwhile, Xcode shows the alert attached: I have 2 questions: Is this a widespread Xcode 13 / iOS 15 issue? Can someone please explain what the message in the alert means "LLDB is likely reading from device memory to resolve symbols"? Is there anything I can do to reduce or avoid this wait?

Hello, I have a test bundle in my application and one of the strong request of our project is to run ui tests from command line having just application build. How to run unit tests on .app file that has a test target? What we tried xcrun devicectl device install app --device <device-identifier> <UITestBundle-Runner.app> xcrun devicectl device process launch --device <device-identifier> --start-stopped <com.apptestbundle-Runner.xcrun> It launches and is waiting pid to be attached. In lldb: device select <device-identifier> device process list Seeing process 'UITestBundle-Runner' pid. device process --pid 'pid id' It attaches and I can see 'debugserver' in the pid list, but it does not start testing and I need tests to start and run. Thanks!

Hi 👋 I need assistance in attaching the to the pid in terminal. In lldb mode I am connecting to the pid using device process attach --pid <pid-id> which gives me an error Process 505 stopped * thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP frame #0: 0x00000001d505c808 libsystem_kernel.dylib`mach_msg2_trap + 8 libsystem_kernel.dylib`mach_msg2_trap: -> 0x1d505c808 <+8>: ret Thanks

If one would like to perform network debugging that involves toggling wireless on and off while still remaining connected to the debugger, how can one disable wireless connections of their devices to Xcode?

I'm writing a C/C++ command line program which, at some point, calls IOHIDManagerOpen. I've added both my program executable and lldb as permitted for input monitoring (as far as I remember, my program was added after showing up a permission prompt, I've added lldb manually later, trying to resolve the problem). My problem is that when I run my program from within lldb in Terminal, the call to IOHIDManagerOpen returns kIOReturnNotPermitted. When I run my program directly in the terminal session (without lldb), this call returns kIOReturnSuccess. Such behaviour means it will be impractical to use lldb for any debugging of this program. What can be done to make lldb session behave the same way, the normal execution works? I'm on: 23.2.0 Darwin Kernel Version 23.2.0: Wed Nov 15 21:55:06 PST 2023; root:xnu-10002.61.3~2/RELEASE_ARM64_T6020 arm64 and: lldb-1500.0.200.58 Apple Swift version 5.9.2 (swiftlang-5.9.2.2.56 clang-1500.1.0.2.5)

As I trying to check "Publishing changes from within view updates is not allowed, this will cause undefined behavior." within the app in Xcode 15.4 , but unable to see that in the specific file but is getting logged in the Xcode , even I tried adding debugger for "All runtime issues" , its not working. Console like Opposed to this I am expecting this to be visible in the file as Anyone can pls help me in there!! Thanks!!

I am using the Leaks instrument, and it has identified a bunch of 32 and 48 byte "Malloc" leaks. I would like to see a hex dump of some (or all) of those areas. I think if I can see what is in them I can get a better idea about what is triggering the leak. I'm pretty sure it is a real leak. What is the easy way to do this? Can it be done inside instruments, or do I need to run my app under instruments and also attach via lldb and hexdump from lldb? (can I attach lldb and instruments at the same time?) If it matters I'm debugging an iPadOS app, and it is written in Swift plus ObjC, plus ObjC++, oh, and some straight C++.

Visual Studio, Stadia, and JetBrains are supporting natvis files, where Xcode is still stuck on lldb python files that even Xcode no longer uses to debug data structures. Apple has converted all of their scripts to native code, so there are no samples of how to write complex lldb visualizer rules. There is already an lldb-eval that can bring in natvis files, so something like this should be brought to Xcode. C++ packages like EASTL only ship with a natvis file, and it's far simpler to edit and write than the lldb rules and python scripting.

I have a sandboxed app in /Applications. I'm attempting to shoot a problem with LLDB, so I cd to /Applications/app-name/Contents/MacOS and do lldb programname. However, once I fire it off with "r" it dies instantly with: error: process exited with status -1 (lost connection) Should this work? Should I try signing the lldb executable? Thanks!

After upgrading from Xcode 14.3 to Xcode 15.2, I am observing unexpected behaviour in Xcode when printing string variables to the console. Specifically, blank lines do not show up (they previously did, as expected, with Xcode 14.3). Steps to reproduce: Put this multiline (Swift) string literal in some Swift file (two lines with one blank line in between) let test = """ line1 line3 """ let Xcode hit a breakpoint in the file with the string print the string value to Xcode console: (lldb) po test "line1\n\nline3" print the same string, cast to NSString, to Xcode console: (lldb) po test as NSString line1 line3 Observed: The blank line is missing in the "po test as NSString" output Expected: There should be a blank line between line1 and line3 I'm running macOS 13.6 (22G120) and Xcode 15.2 (15C500b)

Xcode15.2 LLDB 太慢了，简直无法工作，好几分钟才断点出变量传，然后断点无法跳出继续执行。Xcode14.1则不会有这些问题，望修复。

I am trying to debug a kernel panic in our kext. I can attach to the target Mac over ethernet if I: cause an NMI using add an IOPanic call to my kext and cause it to be executed use Dtrace to invoke a panic However if I reproduce the kernel panic which I am investigating, the Mac just restarts. How can I make the Mac wait for me to attach with lldb rather than restarting? My target configuration is: Mac is 2021 M1 Pro 14" MacBook Pro macOS 14.2 (23C64) Network: Apple Thunderbolt 3 <-> Thunderbolt 3 adapter + Apple Thunderbolt 2 to ethernet adapters Boot-args = "debug=0x44 wdt=-1 kdp_match_name=en8" (I have also tried debug=0x104C0C)

Topic : Attaching debugger via lldb to remote process on tv device Current status I launch an app on a remote tv device that is paired to a macbook using the command xcrun devicectl device process launch --start-stopped -d XXXX-XXXXXX, com.metasample.SampleApp -j launch.json App is launched in stopped state and waiting for debugger to be attached to continue execution Using the XCode->Debug->Attach to Process, I am able to select the process and connect to the process and execute the app through the debugger. Expectation I would want to replace step 3 and use a command line instead to attach the debugger to the remote process instead of doing it via XCode.(the reason is to automate the execution without any manual intervention) I know the process id of the app on the remote tv device when i inspect the launch.json file that is created when the launch the app. eg pid 312 I also know the ip address of the device eg ip 192.168.178.29 However I do not know how to establish the debug session using lldb from command line. I launch lldb in the command line and execute these commands platform select remote-tvos target create /Users/works/apps/SampleApp-Payload/SampleApp.app/SampleApp gdb-remote 192.168.178.29: "what is the port?" - I do not know what port to connect to? Many Thanks for your suggestions and inputs on how to connect to the remote app via command line lldb.

Hello, is there any way that I can automatically fold items in the console? I do log all API requests and responses, printed in a nice json to console. It works well, but having a lot of requests makes the console very big, and it kills readability, I have noticed that I can manually fold json printed in console with CMD+OPTION+Left shortcut. I am asking if that's possible to fold everything, or just display first lines of the console. So I can see more entries easier, and if I need I can unfold, or disable Line Wrap, to see details. I am attaching the photo of how code folds works there. It's all good, but I need to do it one by one, which is bad. If I could select everything and auto-fold, or It has the line wrap disabled. I
