GestureButton

About GestureButton

GestureButton is a SwiftUI button that can trigger many different gesture-specific actions with a single gesture.

You can use a GestureButton just like a regular Button, and can define different actions for different gestures:

struct ContentView: View {

    @State private var isPressed = false
    
    var body: some View {
        GestureButton(
            isPressed: $isPressed,
            pressAction: { print("Pressed") },
            releaseInsideAction: { print("Released Inside") },
            releaseOutsideAction: { print("Released Outside") },
            longPressAction: { print("Long Pressed") },
            doubleTapAction: { print("Double Tapped") },
            repeatAction: { print("Repeating Action") },
            dragStartAction: { value in print("Drag Started") },
            dragAction: { value in print("Drag \(value)") },
            dragEndAction: { value in print("Drag Ended") },
            endAction: { print("Gesture Ended") }
        ) { isPressed in
            Color.yellow // You can use any button content view.
        }
    }
}

You can pass in various delays and timeouts to change how the button behaves, e.g. the max time between two taps for the taps to count as a double-tap. You can use any View as the button label.

Installation

GestureButton can be installed with the Swift Package Manager:

Getting Started

A GestureButton can be used just like a regular Button, as shown above, but needs some extra handling when used within a ScrollView.

In iOS 17 and earlier, you have to pass in a GestureButtonScrollState into the GestureButton initializer, for the button to not block the scroll gesture.

In iOS 18 and later, you must pass in a GestureButtonScrollState and apply it to the scroll view as well:

struct ContentView: View {

    @StateObject private var scrollState = GestureButtonScrollState()
    
    var body: some View {
        ScrollView(.horizontal) {
            GestureButton(
                scrollState: scrollState,
                pressAction: { print("Pressed") },
                label: { isPressed in
                    Color.yellow // You can use any button content view.
                }
            )
        }
        .scrollGestureState(scrollState)
    }
}

A future version of this library should aim to streamline this setup to only require the modifier. The gesture button should then access the state as an environment value.
