有没有办法避免SwiftUI GeometryReader阻止嵌套视图在列表中增长？

struct ContentView: View {
    @State private var itemHeights: [CGFloat] = []
    
    var body: some View {
        List {
            ForEach(0..<10) { index in
                GeometryReader { geometry in
                    Text("Item \(index)")
                        .frame(height: self.itemHeights[index])
                        .background(GeometryReader {
                            Color.clear
                                .preference(key: ItemHeightKey.self, value: geometry.size.height)
                        })
                }
                .onPreferenceChange(ItemHeightKey.self) { height in
                    self.itemHeights[index] = height
                }
            }
        }
    }
}

struct ItemHeightKey: PreferenceKey {
    static var defaultValue: [CGFloat] = []
    
    static func reduce(value: inout [CGFloat], nextValue: () -> [CGFloat]) {
        value.append(contentsOf: nextValue())
    }
}
