Overview

To recognize a long-press gesture on a view, create and configure the gesture, then add it to the view using the gesture(_:including:) modifier.

Add a long-press gesture to a Circle to animate its color from blue to red, and then change it to green when the gesture ends:

struct LongPressGestureView: View {
    @GestureState var isDetectingLongPress = false
    @State var completedLongPress = false

    var longPress: some Gesture {
        LongPressGesture(minimumDuration: 3)
            .updating($isDetectingLongPress) { currentstate, gestureState,
                    transaction in
                gestureState = currentstate
                transaction.animation = Animation.easeIn(duration: 2.0)
            }
            .onEnded { finished in
                self.completedLongPress = finished
            }
    }

    var body: some View {
        Circle()
            .fill(self.isDetectingLongPress ?
                Color.red :
                (self.completedLongPress ? Color.green : Color.blue))
            .frame(width: 100, height: 100, alignment: .center)
            .gesture(longPress)
    }
}
