How to get my IONIC App compatible with Multitasking on iPad in iOS 9

When I submit my app to App Store i get following message

Invalid Bundle Error - “requires launch story board”

But this can be easily solved by adding following key in info.plist


This will be a quick fix.

But how can I make my app compatible with iOS9 multitasking.

Is anybody able to get Ionic app working with iPAD multitasking?
