Use one or more storyboards to graphically lay out the user’s path through your app. Most new project templates include a storyboard for the main user interface of the app.
A storyboard is a type of user interface file that you edit using Interface Builder. The components a storyboard are:
Container and content view controllers
Relationship connections between a container and its children
Segue connections between content scenes
Control views used to trigger the segues
