Resources to get started with iOS development

I have the opportunity tonight to teach a lecture to college students interested in getting started with iOS development.  I really have no idea which way the lecture will go, so I haven't really planned out a set agenda for the lecture.  Instead, I came up with a long lists of different topics that I could cover throughout the lifecycle of creating an iOS application, and then jump around based on me soliciting topics at the beginning of class.  Along with those topics, I came up with a list of online resources that would be helpful for someone getting started with iOS development.  I posted them on Github at: https://github.com/obuseme/GettingStartedProgrammingiOS
