I don't usually write about rumors, but the latest report from Mark Gurman on dual-app viewing mode possibly coming to iPad with iOS 9 is too exciting for me to resist a link.
Sources now say that Apple plans to show off the side-by-side feature for iOS 9 using currently available iPad models. The latest plans suggest that the split-screen mode will support ½, 1/3, and 2/3 views depending on the apps. When split, the screen can either display two different apps side-by-side, or multiple views of the same app. This would enable iPad users to see two separate Safari tabs, or compare a pair of Pages documents at the same time. Sources are quick to warn, however, that the feature could still be pulled before next month’s conference, as additional polish would be needed to bring it to the same level as other features that will be making their way into the first iOS 9 beta next month
A new multitasking experience for iPad was one of my big wishes for iOS 9. I had, however, many questions and doubts about the implementation of flexible split-screen on the current generation of iPads. Here's what I wrote:
My issue with requesting a new multitasking experience is that I don't know if it would be possible to make one that doesn't put too much stress on the user. I think that I'd like the ability to see parts of two apps at once, but what if there simply isn't a way to make that work well? What happens when you bring up two apps that require keyboard input – how do you understand which app you're typing into if you have one keyboard and two apps? Can two apps receive touch input simultaneously? Can you open two camera apps at once? What about audio output? I'm not sure why anyone would want to do that, but, in theory, should you be able to run two games at the same time? Would this new mode only work in landscape?
Gurman's report doesn't have any details on how this mode would actually work. How would you activate a second app – with a gesture or a special menu inside apps? Will developers get new tools to optimize their apps for new iPad layouts? Will apps be able to invoke specific apps programmatically (could it be this 'app links' API mentioned in the WebKit source code)?
As I concluded last month, the iPad needs new multitasking features. I'm curious to see what Apple does.
