title: Adding more options to Application Languages in Scheme Options
body: <p>In xcode 6, there is a very nice feature where you can select the language you want to test your app in, without having to change the system language and restarting.
  My system shows only 2 languages, how can I add more ?. I tried adding more languages in system preferences language list, but I still see the same options.</p>
