swift - Storyboard issue in Xcode 6 -

i developing ios 8 app using swift. got problem viewcontroller layout in storyboard. when add together viewcontroller, iphone size not ipad size. app focus on ipad not universal application. checked size in "simulated metrics" there no size ipad except iphone sizes.

but create new storyboard , add together viewcontroller. there no totally issue @ all. happened existing storyboard? , how can prepare it?

thanks, frog

select storyboard in project navigator. utilize file inspector , enable size classes (it's checkbox). solves it.

if don't enabling size classes, disable size classes 1 time again - when dialog appears, specify want maintain ipad size class data. (really, though, should using size classes if ios 8 app.)
