So what path have you chosen? I am a Ruby programmer and want to make an iOS app. I'm planning to use the Stanford course on iTunes to get started. Do you know if that's any good?
I don't think of myself as a visual learner and I tend to avoid screencasts in favour of reading, experimenting, and hands-on learning, but the difference between web development with Ruby and mobile development on iOS is so big that the methodical, step-by-step nature of this course is helping me.
I learn best by immersion and example, so I just picked a project and started building. I looked at prominent open source iOS apps and constantly referred to Apple iOS SDK docs, Apple example code, and several prominent books on iOS development (Hillegass, et al).
If you're more of a methodical or visual learner, use the iTunes U course videos.
Maybe also links to their repos?
Thanks
