From the debugger console window you can use GDB commands,
including calling functions in your code, and functions in
libraries your code links against. So, one way to view a
std::string would be to use the c_str() member function:
x/s myString.c_str()
There may be a way to get Xcode's debugger display to do that for
you automatically -- I haven't tried.
Certainly: you can type something like:
size={(int)$VAR.size()} "{(char *)$VAR.c_str()}:s"
into the summary column of a std::string row in the debugger window
and from then on, some of your std::strings will display their value.
Of course, some won't for no apparent reason, and references to
strings won't display, but it's slightly better than nothing.
