SwiftUI: How to get continuous updates from Slider

Question

I\'m experimenting with SwiftUI and the Slider control like this:

struct MyView: View {

    @State private var value = 0.5

    var body: some View {

Just use the onEditingChanged parameter of Slider. The argument is true while the user is moving the slider or still in contact with it. I do my updates when the argument changes from true to false.

struct MyView: View {

    @State private var value = 0.5

    func update(changing: Bool) -> Void {
        // Do whatever
    }

    var body: some View {
        Slider(value: $value, onEditingChanged: {changing in self.update(changing) }) 
        { pressed in }
    }
}
