A new video from developer Steven Troughton-Smith has emerged on YouTube, showing off the activation of hidden code for split screen multitasking in the iOS 8 beta. The feature is shown off in the iOS simulator on Mac, hence the mouse cursor, awkward two-finger gestures and its rough overall look.
In the video, the three sizes are shown (1/3, 1/2 and 3/4) when using two fingers to scroll to the side. However, it's not evident how to open a second app next to the already opened app, likely because the feature is still being developed.
Split-screen multitasking may initially be limited to the iPad Air, with support for smaller devices, like the iPad Mini and rumored 5.5-inch iPhone 6, at a later date. The feature could also make it to Apple's rumored 12.9-inch "iPad Pro" that may or may not be in development.
