Adding a drag gesture in SwiftUI to a View inside a ScrollView blocks the scrolling

Question

So I have a ScrollView holding a set of views:

    ScrollView {
        ForEach(cities) { city in
            NavigationLink(destination: ...) {

I had a similar problem with dragging a slider at:

This is the working answer code, with the "trick" of the "DispatchQueue.main.asyncAfter"

Maybe you could try something similar for your ScrollView.

struct ContentView: View {
@State var pos = CGSize.zero
@State var prev = CGSize.zero
@State var value = 0.0
@State var flag = true

var body: some View {
    let drag = DragGesture()
        .onChanged { value in
            self.pos = CGSize(width: value.translation.width + self.prev.width, height: value.translation.height + self.prev.height)
    }
    .onEnded { value in
        self.pos = CGSize(width: value.translation.width + self.prev.width, height: value.translation.height + self.prev.height)
        self.prev = self.pos
    }
    return VStack {
        Slider(value: $value, in: 0...100, step: 1) { _ in
            self.flag = false
            DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
                self.flag = true
            }
        }
    }
    .frame(width: 250, height: 40, alignment: .center)
    .overlay(RoundedRectangle(cornerRadius: 25).stroke(lineWidth: 2).foregroundColor(Color.black))
    .offset(x: self.pos.width, y: self.pos.height)
    .gesture(flag ? drag : nil)
}

}
