Let's recap what we have just learned in this chapter:
How Objective-C and Ruby work together
How RubyMotion objects are inherited from Objective-C
How RubyMotion interfaces with C and Objective-C
Memory management offered with RubyMotion
In the next chapter, we will learn how we can use the Model-View-Controller (MVC) design principle in our RubyMotion application. We will discuss in detail about the MVC architecture. Later in the chapter, we will have some hands-on examples to learn how to integrate our mobile application with an external API.
