SwiftUI provides gesture modifier to implement tap gesture on a view. Multiple gesture can be achieved though adding count numbers.
To try it out let’s create a view and add a tap gesture recogniser
struct ContentView: View { var body: some View { Circle() .fill(Color.red) .frame(width: 50, height: 50, alignment: .center) .onTapGesture { print("Circle tapped") } } }
To detect multiple taps, we need to pass number of taps in count parameter
struct ContentView: View { var body: some View { Circle() .fill(Color.red) .frame(width: 50, height: 50, alignment: .center) .onTapGesture(count: 2) { print("Double tap on the circle") } } }
