What is the best practice when making a storyboard for iPhone and iPad?

Question

I'm making an app that would run on iPad and iPhone but only in landscape mode. The first app that I made was only for iPhone using one storyboard and hAny wAny size classes.

1. What are the good practices when designing an app for iPhone and iPad, regarding usage of storyboards and size classes?

2. Should I make 2 storyboards for each one of them? If so, what would the size classes be?

Answer 1

1. You Should use 2 Storyboards. One for iPhone and another for iPod.

Answer 2

No need to create two storyboard, you can design an app using auto layout.

Answer 3

1. Use Size classes. Start from wAny and hAny. Make appropriate changes for each device switching to different sizes. Using container views will make it more handy.
2. Single storyboard should be sufficient for both iPhone and iPad. A storyboard specific to a separate module / User story is preferred.
