Apple talked about its new split screen mode that will arrive on iOS 8, but Apple failed to show much in the way of details at WWDC. Now a video demoing the multi-tasking aid has appeared online.

The code to run iOS 8's split-screen is found in the SpringBoard beta that's in the hands of developers right now. It allows for a screen split of either quarter, half or three quarter sizes.

The split-screen multitasking is already available on Microsoft's Surface tablets as well as several Samsung devices. But this is a first for Apple.

The video shows that in typical Apple style splitting a screen should be intuitively straight forward. A two-finger slide of the screen to one side appears to compact the size down in the three sizes depending on how far across it is pushed.

Pop-up menus don't appear to re-size and centre to fit, causing cut-offs on the screen. Although this is a beta so that may be resolved in the final version.

iOS 8 is due to be released this autumn.
