Chapter 1. Objects from the Real World to the Playground
Whenever you have to solve a problem in the real world, you use elements and interact with them. For example, when you are thirsty, you take a glass, you fill it up with water, soda, or your favorite juice, and then you drink. Similarly, you can easily recognize elements, known as objects, from real-world actions and then translate them into object-oriented code. In this chapter, we will start learning the principles of object-oriented programming to use them in Swift 3 to develop apps and applications.
