Understand iOS gestures
A tap is a brief contact of (usually) one finger on your device’s screen.
To drag is to move a finger across the screen to scroll or pan around content.
Swipe means move one or more fingers across an item or the screen, then let go.
A flick is like swiping, but it’s quicker, and is often used to scroll content more quickly.
Pinch means move two fingers together or apart, usually to zoom in or out.
Touchandhold means lightly rest your finger on an item and wait for a reaction.
