Previous concept for split-screen multitasking (not based on specific rumors)
Besides allowing the operation of multiple apps at the same time, the feature also may allow users to share data such as links and images between apps. The integration of this sharing functionality suggests Apple may open up support for XPC services in iOS, making it easier for developers to share content between apps.
In addition to allowing for two iPad apps to be used at the same time, the feature is designed to allow for apps to more easily interact, according to the sources. For example, a user may be able to drag content, such as text, video, or 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.The multitasking feature, which is said to work in landscape mode only, is likely to land in the 9.7-inch iPad, with its extension to the smaller iPad mini unclear at this time. It may also be a critical feature for the rumored iPad Pro, which may ship sometime in 2015 with a 12-inch display.
