One Storyboard to Rule Them All
Do you really want to write 20 storyboards to cover three sizes of iPhones, the iPad, iPad mini and iPad Pro, and iPad multitasking windows? You don’t have to. Auto layout, size classes and stack views in Xcode 7 make this task easy. You can make one storyboard for all 20 layouts, and sell many apps as universal apps that couldn’t before. We are getting close to the time Apple will require Auto layout and size classes.
In iOS8, Apple made it impossible to code popovers, modal views, Alerts and Split views without size classes. In iOS9, multitasking requires it. But most developers do not know the difference between a regular width and compact width. Doing so, they risk their code becoming obsolete and useless. You need to know size classes, or your code can break in iOS9.
