I've never programmed in ObjC. I see that GDB can be used to debug
Objective-C (assuming this is the same language). I don't know how
data structures are printed but Emacs currently displays them in the
speedbar. It uses a feature of GDB called "variable objects". These are
described in the GDB info manual under the node GDB/MI. The relevant file
for this in GDB is varobj.c, but inspection of this file shows that unlike
C++ and Java, Objective-C isn't treated specially but as for C.

That would be great but you might need to make changes to GDB too. Also
eventually I would like to display watch expressions using tree-widget.el
rather than the speedbar as the icons are more suitable and the timer functions
of the speedbar aren't needed/wanted by gdb-ui.el

Please post to emacs-devel@gnu.org when you need help.
