SwiftUI Gestures

This lesson is part of Swift · All levels

Summary

This lesson discusses user touch gesture handling in SwiftUI such as TapGesture, DragGesture, MagnificationGesture, and RotationGesture. Gestures can be tied directly to the component using a .gesture() modifier for rich interface interaction.

Key points

Modifier '.onTapGesture(count:)' handles both single and double punches
DragGesture tracks the user's touch-to-touch coordinate shift on the screen
Supports temporary state during gesture running using the modifier '.updating()'
Gestures can be combined simultaneously (SimultaneousGesture) or sequentially (SequenceGesture)
