The book bases the first 9 chapters on using .xib files, and only covers storyboards in Chap. 10. I'm wondering if it's possible to convert most any project based on .xib files into a storyboard project.
Specifically, can this be done for the Blue-Yellow Application in Chap. 6? I think this is an interesting example because the root view controller is a bit unusual -- basically just a toolbar used to switch between one of two top-level views (which display above the toolbar). If someone could point me in the direction of converting this project to use a storyboard, I'd be grateful.
