iOS 7 beta brings with it a host of surprising features, one of which is the new way in which the mobile operating system handles multitasking. In iOS 6, a double click on the Home button on your iPhone, iPad, or iPod touch brings up a multitasking bar along the bottom of the screen. On iPhone and iPod touch, it only works in Portrait mode. On the iPad, it works in both Portrait and Landscape screen orientations.
That’s the same in iOS 7, but the visual look of the multitasking system is quite different. Instead of a small bar sliding up from the bottom, you get full previews of each app in the multitasking list. You can swipe left and right to move between apps at will. Also different in iOS 7 beta is the way you force quit apps, to start them anew or prevent certain ones from running in the background.
In iOS 7 beta, double click the Home key as per usual to engage the multitasking system. You’ll see an icon for the app and an app screen preview across your iOS device.
Previously, you’d tap and hold on a multitasking bar app icon and get the app wiggle. You’d then tap the X button to remove it from the multitasking bar, letting it start from a clean state next time you started it up, or keeping it from running in the background.
In iOS 7 beta, all you need to do is swipe the app review up toward the top of your screen, and it will be taken out of the list, essentially doing the same thing: letting it start from a clean state as well as keeping it from running in the background, if the app supported that.
