In this section we went through the basics of programming in Objective-C. We will discuss some basic definitions such as:

• Variables

• dot operations

• Collections

• Functions

We will then learn how to call a function and how to use it. By the end of this section, you should have a better understanding of how a piece of code in Objective-c actually works.

For most everything in here, we will work outside of iOS and we will work on developing command line tools.
