My application supports all devices with 4 inches forward in both orientations.
iPhone - 5, 5S, 5C, 6, 6S, 6+, 6S +, SE
iPad 4, iPad Air, iPad Air2, iPad Pro, etc.
Using the asset catalog for the launch screen, it works fine, but in iPad Pro the application displays a standard keyboard, and iPad has an optimized keyboard that is bigger and does not give a better user experience.
As shown below, the app must use the launch storyboard, not object images, to get an optimized iPad Pro keyboard.

Now the question is how to maintain both orientations during the startup screen storyboard?
How to add different launch images for portrait and landscape modes in a storyboard? Using the iPad size class in both orientations has both regular and regular sizes.
Note. Since its storyboard on the startup screen, you cannot configure a size class with a custom class.
A quick reply is welcome !!
Thanks, Siva
