Gesture detection can be added to SwiftUI views using gesture recognizers. SwiftUI includes recognizers for drag, pinch, rotate, long press and tap gestures. Gesture detection notification can be received from the recognizers by implementing onEnded, updated and onChange callback methods. The updating callback works with a special property wrapper named @GestureState. A GestureState property is like the standard state property wrapper but is designed exclusively for use with gestures and automatically resets to its original state when the gesture ends. Gesture recognizers may be combined so that they are recognized simultaneously, sequentially or exclusively.
