I am trying to add document types to my non-document-based application using the "Document Types" section of the target info panel in Xcode 4.5.2.
Well, I seemed to have worked just once, for one file extension, but I did some modifications to inform quick look that it could display my files as text files.
As a result, it doesn't work anymore, and I can't make it work again.
Let's say my app bundle identifier is com.mycompany.myapp and the file extension for the files I would like to edit is .xyz.
How should I fill the form so that my app becomes the default editor, and quick look knows that it can display all .xyz files as text files ?
