问题
I have made a storyboard using "wCompact" (Compact Width) and "hRegular" (Regular Height") size class. Now when I change to "wAny"|"wHeight" all the components of on the storyboard to be specific that view controller disappears. I want to copy the same design for "wAny" (Any Width) and hAny ("Any Height") size class. How can I do it ? Right now I have placed no constraints on the design just layout. Is there any way to copy it. Following are images in "Compact Width" and "Regular Height" Well I have referred this too, why storyboard ui elements not showing on UIViewController in xcode 6? But i wanted to know if by any means copying across size classes is available in xcode6.

Basically you've done it wrong and you need to start over. Design the basic interface in Any/Any. What you do there will by default be true for all specific classes. Now design modifications to the basic interface in specific size classes.
