iOS has always been dependent on gestures for accomplishing certain tasks, and this is even more the case with iPadOS. But these gestures are hard to discover, and even harder to remember. Do you know how to make the proper three-finger pinch to copy text on your iPad?
Much of the power of iPadOS comes through new gestures, and while Apple offers a Tips app, this app only shows a couple of the new gestures, and none of the older ones. macOS features visual assistance for gestures on the trackpad or mouse, and you can view them in System Preferences > Trackpad, or System Preferences > Mouse. (Of course, you have to know to look there.)
It would be useful if iOS and iPadOS came with similar instructions. They could be in the Settings app, or there could be a dedicated Gestures app, to which users could refer when they want to refresh their memories about how to do something, or to learn about gestures they aren’t aware of. Apple does offer detailed user guides for iOS and iPadOS, but their descriptions of the gestures may not be sufficient for people just learning how to use these devices. The little videos in the macOS preferences, as in the above screenshot, are much easier to understand.
It is a bit of a shame that these powerful features are so hidden. It wouldn’t be that difficult for Apple to provide a more efficient way for users to discover them and get more out of their iPhones and iPads.
