swift swiftui scrollview Swift

I need help solving I've been banging my head against this for hours. I'm encountering a frustrating issue with a `ScrollView` in a SwiftUI app where the scroll position resets whenever I update the state. I'm using Xcode 15 and Swift 5.9, and I'm trying to display a list of items with a header that can be toggled to show or hide additional information. However, whenever I update the state, such as changing the visibility of the header, the scroll position jumps back to the top instead of maintaining its position. Here is a simplified version of my code: ```swift struct ContentView: View { @State private var showDetails = false @State private var items = Array(0...50).map { "Item \($0)" } var body: some View { VStack { Button(action: { withAnimation { showDetails.toggle() } }) { Text(showDetails ? "Hide Details" : "Show Details") } .padding() ScrollView { VStack(alignment: .leading) { ForEach(items, id: \..self) { item in Text(item) .padding() } if showDetails { Text("Additional Details") .padding() } } } .id(showDetails ? "Expanded" : "Collapsed") // Trying to force refresh } .padding() } } ``` Despite using the `.id()` modifier to force the view to refresh without losing the scroll position, it still jumps back to the top. I've also tried wrapping the `ScrollView` in a `GeometryReader` to manage the scroll offset manually, but that didn't yield the expected results either. The documentation suggests that SwiftUI should handle this seamlessly, so I’m puzzled. Has anyone experienced a similar issue or found a workaround to maintain the scroll position when updating the view? Any insights would be greatly appreciated! I'm working on a API that needs to handle this. For context: I'm using Swift on Debian. Any feedback is welcome!
