Last year, online education provider Udacity launched its Nanodegree program. In partnership with AT&T, the initiative’s goal is to help people develop focused vocational specialties in a short period of time. Now, Udacity, created by Google X founder Sebastian Thrun, has started an iOS developer Nanodegree. Enrollment is open until March 10, and the 6 month-to-12 month program costs $200 a month.
