What sort of information ? Regarding AppleScriptability and its implementation, my typical method is to open Script Editor and bring up the "Library" window by pressing ⇧⌘L; after locating the XCode app icon (e.g. by opening the "Applications" folder in Finder), you can then drag the app onto Script Editor's "Library" window, and it should be added to the list given that it's scriptable.
From there, just double click on it, and Script Editor will show you the AppleScript dictionary for XCode, containing all (most) of its terminology and syntax, together with object inheritance. These dictionaries are fairly poorly structured, but also indispensable for formulating code targeted at an application that you've not scripted in the past.
Script Debugger, if you have it, has a builtin dictionary that is much more comprehensive it seems, and gives the feeling of being easier to read, plus, as far as I can tell, negates the need to add an application to its list manually, which one needs to do with Script Editor before you can access the dictionary.
