In this chapter, you learned about an important building block that can be used with any application. We also looked at how to associate values with words that can be used throughout our application. These words are better known as variables. By learning what a variable is and how we can create them, we learned how to utilize a very important piece in creating an iOS application. Consider it your first major step!

Our next step, which will be covered in the next chapter, is learning what types are. In this chapter, we briefly went through what a String value looks like, but we will cover this topic in detail in subsequent chapters. We will cover what String means and how exactly we create String values.
