Storyboards were originally introduced in Xcode 4.2 with iOS 5.0. Storyboards solved the problem of being able to graphically present the flow of screens in an iOS application, and they also provided a way to edit the content of these screens in one place instead of many separate xib files. Storyboards work in the same way with Swift as with Objective-C, and the Swift and storyboards section shows how to integrate Swift code with storyboard transitions.
This chapter will present the following topics:
