- Before Storyboards you had to use XIB files and you could only use one XIB file per view (UITableViewCell, UITableView or other supported UIView types).
- With storyboard, you can see its scenes and how they’re related.
- Describe the transitions between the various scenes. These transitions are called “segues” and you create them by connecting your view controllers in the storyboard. Thanks to segues you need less code to take care of your UI.
- A “scene” represents a view controller in the storyboard.
In conclusion, storyboard saves time on coding UI parts.
