I am developing an NE based System Extension on macOS Catalina 10.15.7 using Xcode 12.4. I have everything in place and my extension is running fine. However, I am not able to attach debugger to my extension from Xcode. I can go to terminal and as root user, I am able to attach lldb to the running system extension. But I am not able to attach the debugger from Xcode using Debug - Attach to Process by PID or Name - Debug Process As - root. Xcode just keeps on Waiting to Attach. If the extension is already running, then I am able to attach by PID but never by name. I would like to be able to start debugger using process name and launch the extension and be able to debug from first line of code in extension. Also, I really like Xcode's contextual debugging where I can see most of the variables and information without any extra effort. With terminal the debugging is comparatively hectic. So, is there any way I can attach to System Extensions by name in Xcode? I have tried using target name as well as extension bundle identifier and several other combinations. From terminal I can attach using bundle identifier of the extension itself.
