The lessons are great for people that have some experience in programming (C/C++) and want to learn Objective-C and how to program for the iPhone. The video lessons are available on iTunes U and the materials are posted on the class website.

For the first assignment (1A) you had to make a simple iPhone application interface in XCode’s Interface Builder. The second assignment of the first lesson (1B) was a little bit more complicated. It includes making a simple command line tool in Objective-C.

The second lecture’s assignment (2A) was based on the assignment 1B and that was also the conclusion of the command line tool.

After some trial and error, I successfully completed the assignment

UPDATE: I removed the full code, but you can still ask for help in the comments. Happy coding!
