I'm testing out the new tab view style PageTabViewStyle() in iOS 14. I know how to get the current tab index but would like to get the current drag position as well so I can create a custom interpolated animation while the user swipes - one that depends on position of the drag (for example parallax effects or scaling an item the closer it comes on to or away from view.

I've tried attaching drag handlers but they don't seem to work as intended anywhere inside this structure. Any ideas? Guessing there might be a way with GeometryReader

  import SwiftUI
  import PlaygroundSupport

  struct TipsView: View {
    @State private var selected = 1

    var body: some View {
        VStack {
            ZStack {
                TabView(selection: self.$selected) {
                    Text("1")
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .background(Color.pink)
                        .tag(1)

                    Text("2")
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .background(Color.red)
                        .tag(2)

                    Text("3")
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .background(Color.green)
                        .tag(3)

                    Text("4")
                        .frame(maxWidth: .infinity, maxHeight: .infinity)
                        .background(Color.blue)
                        .tag(4)
                }
                .indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always))
                .tabViewStyle(PageTabViewStyle())
            }
            .background(Color.black)
            .frame(width: 375 - 60, height: 500)

            Text("Current page: \(selected)")
        }
        .background(Color.white)
        .frame(width: 375, height: 812)

    }
  }

  PlaygroundPage.current.setLiveView(TipsView())

Just saw https://www.hackingwithswift.com/plus/remaking-apps/remaking-the-tips-app that does something very similar. Looks like I need to wrap each individual page item in a geometry reader.. will give that a shot

Did you get anywhere with this one @stammy? I'm trying to achieve similar.

I am too
