Xcode 6 - “universal storyboard” projects will support iOS 7?

Question

如果使用Xcode 6 - 通用故事板开发新项目，它是否会支持其以前的iOS versions （ iOS 7 ）？

Answer 1

您可以在iOS 7上使用通用故事板，但您无法访问大小类和特征集合

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.
