swift swiftui observableobject

I'm stuck trying to I'm sure I'm missing something obvious here, but I'm dealing with I've been struggling with this for a few days now and could really use some help. I have a SwiftUI List that is supposed to display items from an `ObservableObject`, but it is not updating when the underlying data changes. I'm using the following setup: ```swift class Item: Identifiable { var id = UUID() var name: String init(name: String) { self.name = name } } class ItemList: ObservableObject { @Published var items: [Item] = [] func addItem(name: String) { let newItem = Item(name: name) items.append(newItem) } } struct ContentView: View { @ObservedObject var itemList = ItemList() var body: some View { VStack { List(itemList.items) { item in Text(item.name) } Button(action: { itemList.addItem(name: "New Item") }) { Text("Add Item") } } } } ``` However, when I tap the "Add Item" button, the `List` does not reflect the newly added item. I confirmed that the `addItem` method is being called because I can see debug output in the console. I also tried using `@StateObject` for `itemList`, but the behavior remains the same. I am running this on iOS 17. Any insights on why my list is not updating as expected? I’ve also tried wrapping the `addItem` call in `DispatchQueue.main.async` just in case there was a threading scenario, but that didn’t help either. Any suggestions would be greatly appreciated! My development environment is macOS. My development environment is macOS. Am I missing something obvious? This issue appeared after updating to Swift latest. Any suggestions would be helpful. I'm developing on Debian with Swift. Am I approaching this the right way? I'm using Swift stable in this project. Hoping someone can shed some light on this. I'd really appreciate any guidance on this.
