The app dock in iOS 11 is a lot more fluid and dynamic than it was in older versions iOS.
It’s not just for the Home screen anymore – it can be brought to the fore from any app, providing quick access to your favorite apps.
Whatever you’re doing on your iPad, you can access the app dock with a quick swipe up from the bottom of the screen. Continuing to swipe will not only reveal the dock, but the Cover Sheet as well.
In addition to the usual apps you have selected for the dock positioned to the left, you’ll find that Apple recommends three more apps to the right. These can be your most recently used apps, or even the ones you accessed last on your iPhone or Mac.
