I just want to output the version number of my ios application in a settings file.
I understand that I have to add the settings file to the application folder.

NSUserDefaults doen't write any values to a settings file. It will only save data in the user defaults plist in your app.
To save something in another file you will have to write this your own. Maybe this will help:
