Select your target, then choose Model > Class Model > Quick Model. In the resulting class diagram, show the Model Browser. Sort it on the Type column.

You can do a multiple selection on all the ivars and copy them to a text file.

If you save the Class Model file in your project, it will update as you add classes, ivars, and methods to the target.
