Let’s start with the word “storyboarding”. This is an action that is used in the art industry to sketch out scenes and building a visual path for making a movie, TV show, comic book, video or game. In the process of “storyboarding” you make storyboards which are the physical drawings.
I think you mean to compare Composer to Storyboard, two scene managers that we offer to us in Corona. But just to fully cover the bases, Apple also uses the term “Storyboard” in Xcode. It’s their multiple scene manager. Because Corona and Xcode are doing similar things, it helps to be clear which one you’re talking about. For the most part Corona SDK users will never need to mess with Xcode’s storyboards.
Now on to Corona.
Corona Labs needed a scene manager, basically a way you could create multiple screens for your app and switch between them. We named that scene manager “Storyboard” (well before Apple started using the term). Several years ago, we needed to upgrade the Storyboard scene manager and were heading towards Storyboard V2, but we made enough breaking changes that we decided to call the new scene manager Composer so as not to break existing apps. Therefore Composer is Storyboards newer, better brother and after a couple of years, we have retired Storyboard.
Unless you have old code that absolutely needs Storyboard, then you should be using Composer. So to summarize:
Composer is Storyboard V2 and is what we offer today…
Storyboard is an API module for managing scenes – in Corona Terms that is retired.
Storyboard in Apple Terms is a way to have multiple scenes in a native app but is also a design tool.
Hope this helps
