LLDB crashes whenever Breakpoints are added

I have a project in Xcode 10.1 which contains both Objective C and Swift code.Whenever I apply breakpoints in my swift code the LLDB crashes, which eventually end the debugging session.I am completely stuck in this scenario as I cannot debug my code.I have tried moving the breakpoints to other lines(suggested by some other posts), but its not working.
Is there any workaround on this?
Message from debugger: The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'.

Complete crash log
The crash is happening in swift code, Objective C code is working fine. Also, it is not occasional, it is happening every time.
I have also tried clearing all Xcode caches and derived data.

I meet the same situation, hopes my solution helps you.
The reason of my Xcode LLDB crashing while adding breakpoints is that my project name (Security) is same to Apple's framework.
After switch project name to another random name, the problem solved.

Xcode injects the dynamic library libViewDebuggerSupport.dylib, which causes the crash. And problematic *.dylib is
/System/Library/PrivateFrameworks/WirelessDiagnostics.framework/Versions/A/Libraries/libprotobuf.dylib
Fixing the custom allocator is the one of the options, but I want to avoid doing it.
Do you know any way to prevent XCode from injecting libViewDebuggerSupport.dylib?

It is appeared to be a bug in Mojave. Apple is working on fixing it, but they did not give me any ETA.
For now I fixed the crash by fixing my custom allocator.

Patching a Mach-O binary with LC_LOAD_DYLIB requires reboot to work

I'm patching a Mach-O binary with a dylib (by appending a LC_LOAD_DYLIB command at the end of the load commands + adjusting the mach header's sizeofcmds + incrementing its ncmds) and I would expect to be able to compile over and over the dylib itself and just rerun the binary.
However, for some reason, when doing so, after the first run, the binary crashes for various reasons (e.g EXC_CRASH or EXC_BAD_ACCESS at different addresses)
If I restart the machine, everything works perfectly fine(the lib is patched and the exec runs). I bet this has to do with some obscure (for me at least) memory mapping or caching the dynamic linker does, but my expertise in that area is slim. Any chance you guys know something about it?

This was due to library image not loaded in release build. I didn't added library in 'Linked Binary With Libraries'.

Xcode 5.02 crash on opening any xib - Yosemite

I am running Yosemite 10.10.4 on a Macbook Air. I have a number of Xcode projects that worked successfully under Xcode 6.4. However, I downloaded Xcode 5.02 from Apple in order to use the Big Nerd Ranch book "IOS Programming" which is written for Xcode 5. Any time I open a xib file, Xcode crashes. As suggested, I opened the console app,found the crash log, and copied it.
