LLDB Tracing Feature

Can someone share a Tracing for-noob introduction please? Whenever I put ‘thread trace start’. Below is what I got. Instruction tracing is extremely helpful while doing assemble level debugging.
(lldb) thread trace start
error: Tracing is not supported. Tracing is not supported. jLLDBTraceSupported is unsupported

I think this belongs in the LLDB category instead. Try there.
