You are likely referring to the custom data formatters, a feature in
Xcode which allows developers to customize the information displayed
for variables in the debugger data view. Simple, customized expressions
can be entered directly into the GUI using a simple format string --
you can find more information on this in the help document "Viewing
Variables and Expressions", which can be found by:
1) Opening Xcode
2) Selecting "Xcode Help" under the "Help" menu
3) In the window that comes up, select the "Debugging" link on the
left-hand side of the "Xcode Help" document
4) From the nested content that appears beneath the "Debugging" link
(after clicking on it) select "Viewing Variables and Expressions"
5) From that page, scroll down to the "Using Custom Data Formatters
to View Variables in the Debugger" section
Or, you can just open the file directly at:
file:////Developer/Applications/Xcode.app/Contents/Resources/
English.lproj/Xcode_Help/Debugging/chapter_8_section_9.html
For types which require more complex processing, a mechanism for
writing a plugin bundle to generate descriptions for variables has been
provided. For developers interested in exploring this feature, some
interim documentation is located in the file 'DataFormatterPlugin.h',
which resides inside the Xcode application bundle
(/Developer/Applications/Xcode.app/Contents/PlugIns/
GDBMIDebugging.pbplugin/Contents/Headers/DataFormatterPlugin.h).
Hope that helps.

I thought I had seen an article about how to add your own custom
"Summary" to your variable types. Like when you have a variable of
type WindowRef and the Summary column in the debugger says
'title="Window" index=0'. I would like to do this for a few of my
classes.
