On page 141 there is the following instruction for LLDB:
(lldb) breakpoint set -o -S "-[NSWindow mouseDown:]
This yields an error:
error: invalid boolean value '-S' passed for -o option
(lldb) help breakpoint set, it seems the
-o option needs an argument. I tried this and it seems to work:
(lldb) breakpoint set --one-shot true -S "-[NSWindow mouseDown:]"
Have a great day!
