Summary
This chapter presented two sample iOS applications, one in which the UI was created programmatically and another in which the UI was loaded from a storyboard. Together with an overview of classes, protocols, and enums and an explanation of how iOS applications start, this chapter gives a springboard to understand the Xcode templates that are frequently used to start new projects.
The next chapter, Storyboard Applications with Swift and iOS, will go into more detail about how storyboards are created and how an application can be built from scratch.
