Unexpected Layout Behavior with SwiftUI and State Management in iOS 17
I need some guidance on I've been struggling with this for a few days now and could really use some help. I'm experiencing a frustrating scenario with my SwiftUI application running on iOS 17. I have a view that should update its layout when the user toggles a switch, but instead, it seems to retain the previous layout state. The toggle is linked to a `@State` variable that controls whether a list of items is displayed or not. Here's a simplified version of my code: ```swift struct ContentView: View { @State private var showList: Bool = false var body: some View { VStack { Toggle("Show List", isOn: $showList) .padding() if showList { List { ForEach(0..<10) { item in Text("Item \(item)") } } .animation(.default, value: showList) } } } } ``` The question arises when I toggle the switch. Initially, the list is hidden, and when I toggle it on, I expect the list to appear smoothly. However, the layout update doesn't seem to trigger as expected; the list appears without animation, and the view layout looks janky. I have tried wrapping the `List` in an `if` statement and even added an animation, but nothing seems to help. Additionally, I checked for any conflicting modifiers that might affect the layout, and I ensured that I am on the latest version of Xcode (15.0) with all iOS 17 SDK updates. In the debug console, I see the following warning that seems related: `Warning: Attempting to use a view that has no layout applied`. This makes me suspect that the layout pass is not being executed correctly when the state changes. I've also looked into using `@Binding` and `@ObservedObject` instead, but since the state is isolated to this view, I believe `@State` is appropriate. Is there something I'm missing in the way SwiftUI handles state changes and layout updates? Any help would be greatly appreciated! How would you solve this?
