How to Use Split View
Enter Split View
With a Split View-compatible app already open, drag another’s icon from the Dock to the left or right edge of the screen. The first app will shrink a little; let go and the second one will snap into position, filling a quarter of the screen’s width. As in iOS 10, drag the handle on the divider to adjust the split. Swap in a new app
Pick up an app’s icon from the Dock or Home screen, then open the app switcher, tap the preview of the two apps that are already in Split View, drag the icon over the app you want to swap out so its portion of the screen goes dim, then let go of the icon. Apps outs ide the Dock
To add an app to Split View (or Slide Over) that’s not in the Dock, find it on the Home screen and start to drag it, keeping it held. While doing that, tap the icon of the second app you want to work in, or get to it through the app switcher, and use an earlier method to drop the first app into Slide Over or Split View. Toggle between modes
There’s a handle above the right app in a 50:50 split, or above whichever app is allocated less space; use this to switch either app’s mode. Dragging up or down from the handle toggles the app below between part of the split view and a movable window on top of another app. Siri app suggest ions
The method from the previous tip also works with app icons in Spotlight’s Siri App Suggestions widget – that’s the Spotlight entered by swiping downward on the Home screen. You can’t do this with the eponymous widget in the Today view, because you can’t open the Dock or the app switcher from there. Use three or four apps
With two apps open in Split View, open a third in Slide Over – drop it over the dividing line to avoid replacing one of the others. The fourth can be a video from an app that supports iOS’s Picture in Picture mode; like Slide Over, you can tuck it off the screen’s edge to gain room.
