SwiftUI's LazyVStack causing layout issues when using GeometryReader on iOS 17

swiftui geometryreader lazyvstack swift

I'm working on a personal project and I tried several approaches but none seem to work. I'm wondering if anyone has experience with I'm updating my dependencies and I'm confused about Could someone explain I'm working with a layout question when using `LazyVStack` in combination with `GeometryReader` in my SwiftUI app on iOS 17..... The scenario arises when I try to position elements based on the available height from `GeometryReader`. The app behaves unpredictably: sometimes the items overlap, and other times they don't appear at all. Here’s a simplified version of my code: ```swift struct ContentView: View { var body: some View { GeometryReader { geometry in ScrollView { LazyVStack { ForEach(0..<50) { index in Text("Item \(index)") .frame(width: geometry.size.width, height: 50) .background(index % 2 == 0 ? Color.blue : Color.green) .overlay(Text("Geometry Height: \(geometry.size.height)").foregroundColor(.white)) } } } } } } ``` When I run this code, I get overlapping items in some scenarios, and I see no visible content in others, especially when the scroll view’s content size exceeds the screen height. I've tried wrapping the `LazyVStack` in another `VStack` and modifying the frame for the `ScrollView`, but nothing seems to solve the scenario. Can anyone guide to understand what's going wrong and how to properly implement this combination without layout issues? Is there a better practice for using `GeometryReader` in this context? I've also checked for updates and made sure my Xcode is on version 14.1. Any insights would be greatly appreciated! I'm developing on Ubuntu 22.04 with Swift. Am I approaching this the right way? What am I doing wrong? Thanks for taking the time to read this! My team is using Swift for this service. Could this be a known issue? I've been using Swift for about a year now. This is part of a larger mobile app I'm building. Any pointers in the right direction? I'm working on a mobile app that needs to handle this. Hoping someone can shed some light on this.
