You can think of storyboards as a graph of all your view controllers connected by segues that dictate the transition between them.

The benefits of storyboards don’t stop there. They also make it easy for developers to create static table views without a data source. How many times have you wanted to create a table view that’s not bound to a real data source—for example, a table that shows a list of options instead of data.
