Can someone explain in simple words the difference between .xib and .storyboard?
Apple introduced the concept of
"storyboarding" in iOS5 SDK to simplify and better manage screens in your app. You can still use the
.xib way of development.
UIViewController had an associated
.xib with it.
Storyboard achieves two things:
.storyboard is essentially one single file for all your screens in the app and it shows the flow of the screens. You can add
segues/transitions between screens, this way. So, this minimizes the boilerplate code required to manage multiple screens.
Minimizes the overall no. of files in an app.
You can avoid using
Storyboard while creating a new project by leaving the "Use Storyboard" option unchecked.
