“LLDB crash”

Hi all:I watched the WWDC15 talked titled What's New in UIKit Dynamics and Visual Effects. Around the 16:00 minute mark the speaker refers to UIDynamicAnimators debugEnabled feature.He states:• Pause the debugger• Find a reference to your UIDynamicAnimator• Set debugEnabled to trueNow, this is likely something very trivial. However, my LLDB skills are poor. If anyone could enlighten me as to how I would go about doing this the right way, it would be very much appreciated.The steps I've currently tried are:• Run the app• Hit 'pause' in the debug area• Search in local variables segment to the left of the console (it's always blank)• I've tried referring to the animator by the variable name I gave it, 'animator', but the console returns an error stating the command is invalid• I've tried using 'expr animator.debugEnabled = true' - same issue.Do I need to edit my scheme to be in a specific mode? Really quite lost.Thanks in advance for any help.

Chrome has started crashing almost immediately after startup. I've reported the issue to the Chrome team here: https://issues.chromium.org/issues/385433270 I'm hoping to debug the issue a bit more myself. This page from the Chrome team https://chromium.googlesource.com/chromium/src/+/master/docs/mac/debugging.md#chrome-builds suggests using the follow to strip off the protections: codesign --force --sign - path/to/Google Chrome.app However, applying that seems to have no effect: % codesign --force --sign - /Applications/Google Chrome copy.app /Applications/Google Chrome copy.app: replacing existing signature /Applications/Google Chrome copy.app: resource fork, Finder information, or similar detritus not allowed % lldb /Applications/Google Chrome copy.app (lldb) target create /Applications/Google Chrome copy.app Current executable set to '/Applications/Google Chrome copy.app' (arm64).

Hi, I am working on a quite huge source code in which the breakpoint function is critical but unfortunately, XCode does not hit the breakpoint. To illustrate the problem clearly, I simplified the step to help you reproduce. XCode version: 12.5 OSX version: 11.3 Steps: 1, Pull the source of WebRTC, build it with is_debug=true and symbol_level=2 I ran the steps below: Note: This forum does not allow me to post the actual link, so please let me post how to reach there. A Viste webrtc.org/support/overview B Select Native development in the left pane. C Select iOS link on the page. D Go through the steps till and include Using Xcode 2, I open the XCode project and select AppRTCMobile , set the breakpoint at main.m, and hit the play button, XCode did build the source yet the breakpoint does not get hit. 3, I suspected that the problem might be the ninja build code inside the huge source, so I made an experiment using lldb to load the binary, it is actually working, here is the copy of messages: Load the ap

Hi, I am using Mohave 10.14.6 on a work computer with XCode 11.2 having recently been upgraded from High Sierra. Before the upgrade, I had been successfully using lldb-mi as part of my cross-platform C++ debugging sessions; this binary file had been present in the /Applications/Xcode.app/Contents/Developer/usr/bin folder before the upgrade. After the upgrade, lldb-mi is gone! How do I get it back? I see this is also happening to Catalina developers (not just Mohave). There are bugs debugging certain C++ elements in lldb thus the need for lldb-mi. How do I get lldb-mi back? A quick look through /usr/local/bin and other spots didn't locate it either unless I missed something? Thanks in advance for anyone's help.

I'm getting the error: ** Warning: Error creating LLDB target at path '/Users/tantan/Library/Developer/Xcode/DerivedData/Videe-bpukzfmjaxewiuaiolulcqllukjg/Build/Products/Debug-iphonesimulator/[AppName].app'- using an empty LLDB target which can cause slow memory reads from remote devices.** Is there anyone who can explain to me what the reason is and how can fix it? Thanks,

Here's a simple C++ program: cpp #include stdio.h int main() { printf(Hello worldn); return 0; } On my M1 Macbook air, I can compile, run, and debug this program successfully: bash % clang++ hello.cpp -g % ./a.out Hello world % lldb a.out (lldb) target create a.out Current executable set to '/Users/sam/build/a.out' (x86_64). (lldb) run Process 55681 launched: '/Users/sam/build/a.out' (x86_64) Hello world Process 55681 exited with status = 0 (0x00000000) When adding -arch arm64, it builds and runs, as expected: bash % clang++ hello.cpp -g -arch arm64 % ./a.out Hello world But debugging seems to fail: bash % lldb a.out (lldb) target create a.out Current executable set to '/Users/sam/build/a.out' (arm64). (lldb) run error: process exited with status -1 (attach failed ((os/kern) invalid argument)) Is there anything special I need to do to get lldb to work with an executable compiled with -arch arm64?

Ever since updating to Xcode 16.3, auto-completing variable names in lldb does not work. Is this a known bug? Is there a workaround to get it do auto-complete again?
