Both Objective-C and Swift have been suggested and Swift is an option in the course poll as well as the option named "App(iPhone/Android)" so I suggest that you vote over there, if you have not already.
The course poll was created to get input from the community to help decide which course should be added to Codecademy next, and once the poll has been closed, the new course will be decided and it will start being put together.
FYI in the poll (currently):
App (iPhone/Android) 20%;
Swift, for building iOS apps 3%
Thank you for your inquiry. If you are not sure about something, don't hesitate to ask.
