How to get frames (size and coordinates) for different views in SwiftUI?

I need to get frames for multiple views inside a VStack. I think using the GeometryReader but it returns the necessary parameters only for the parent. How can I get these parameters for each view on the screenshot below?

We can use the GeometryReader inside the overlay on needed views and store necessary frames in an array or as separate variables.

ForEach(0..<n) { number in
  YourView()
    .overlay(
      GeometryReader { geometry in
        Color.clear
          .onAppear {
            self.buttonFrames[number] = geometry.frame(in: .global)
          }
        }
    )
}
