Case 1

Case 2

Answer 1

The non-adaptive manual segues are deprecated and they don't adapt to the screen size and orientation, that's why they are called "non-adaptive".

With iOS 8, the size classes were introduced (Regular and Compact) and the new Adaptive Segues adapt to these, like when you turn your iPhone to landscape orientation, the status bar will disappear and the navbar will shorten in height.
