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

Question

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?

Answer 1

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)
          }
        }
    )
}
