Conversely, older generation models and iPad mini will have "Slide Over," allowing them to slide in a smaller version of a second app from the side of the screen. Apple gives examples like quickly responding to a tweet or text message while browsing Safari as a prime example. Although, unlike Split View, Slide Over isn't true multitasking as the app relegated to the background can't be interacted with while the second app runs on the side of the screen.
iOS 9 will also bring picture-in-picture to allow users to watch video while browsing around within other apps. By simply pressing the home button when watching a video or even using FaceTime, users can browse their iPad as normal while a smaller boxed video keeps running in the corner of the screen.
