As far as I know, you won't be able to do it visually in XCode. (You could maybe attempt to edit the .rc files manually in a text editor, though.)
The GUI resources for Reaper and Reaper extensions are supposed to be done on Windows in Visual Studio, and for OS-X they are translated from the Microsoft resource files into C++ code with the PHP script (mac_resgen.php) that is included in the WDL/SWELL source tree.
