Split-screen multitasking would let iPad users run two apps at the simultaneously, side by side in landscape mode -- a feature that Microsoft often criticizes the iPad for lacking. Sources also claim that the feature is designed to allow for apps to interact with each other. For instance, a user can drag content (text, video, images) from one app to another.
Apple is said to be developing capabilities for developers to be able to design their apps to interact with each other. This functionality may mean that Apple is finally ready to enable “XPC” support in iOS, which means that developers could design App Store apps that could share content.
Currently the feature exclusively works in landscape mode, and has been designed for the 9.7-inch iPad displays. It is unclear if the multitasking feature would come to the smaller-screened iPad Minis. Split-screen multitasking would also work well with the rumored 12-inch iPad Pro.
