Dictionary seems to be several versions ahead of the Apple documentation (2007). I found a good blog post about it, but everything seems different now. I installed Xcode (including the command line tools) but nothing is where it’s supposed to be (e.g. Developer does not get created and there is no Dictionary Development Kit). I would like to make a pretty complicated dictionary, so I’d like to make this work instead of converting file types.
Where is Developer/Extras/Dictionary Development Kit now?
Everything that was in /Developer is now embedded in the Xcode.app folder. Some items were not brought over by default and must be downloaded manually from https://developer.apple.com/downloads/index.action
You want the “Auxiliary Tools” for your version of Xcode.
