Xcode 6 - "universal storyboard" projects will support iOS 7?

Question

If a new project is developed using Xcode 6 - universal story board, will it support its prior iOS versions (iOS 7) ?

Answer 1

You can use a universal storyboard on iOS 7, but you won't have access to size classes and trait collections

Answer 2

You need to check once by running your app on iOS 7. There are some feature which works on iOS 8 and we need to handle for iOS 7 differently.

For eg

I created gradient colour on x-code 6, it worked on iOS 8 but not on iOS 7. so need to handle that too.
