Do we need to use 2 Storyboard for a Universal app?

Question

I have a project for iPhone and iPad. The iPad needs a split view controller. Do we create two separate storyboards? One for iPhone (using autolayout we can support all devices)

Answer 1

On iOS 8, you do not need two storyboards since a single storyboard can handle both iPhone and iPad; also, UISplitViewController is supported on the phone on that OS.

For earlier releases of iOS, you'll need two storyboards.
