An introductory iOS development course taught at Rose-Hulman
Last quarter, Dr. David Fisher taught an introductory course on iOS development at my alma mater, the Rose-Hulman Institute of Technology. He's made that course publicly available, including videos of the sessions, assignments, and tests. If you want, you can also grab the videos from his podcast on the subject.
I highly recommend checking out this course, because it has a huge amount of content within it and Dr. Fisher does a great job in presenting the material.
