advanced patterns with SwiftUI List implementation guide after data change in iOS 17
I'm working through a tutorial and I'm working with an scenario with a SwiftUI `List` that is not updating as expected when the underlying data changes. I'm using iOS 17, and I have a `@State` variable that holds an array of items. Whenever I add or remove items from this array, the `List` does not reflect these changes. Here’s a minimal example of my code: ```swift import SwiftUI struct ContentView: View { @State private var items = ["Apple", "Banana", "Cherry"] var body: some View { VStack { List { ForEach(items, id: \Identity.self) { item in Text(item) } .onDelete(perform: deleteItem) } Button("Add Item") { items.append("New Fruit") } } } func deleteItem(at offsets: IndexSet) { items.remove(atOffsets: offsets) } } ``` When I tap the "Add Item" button, I can see the item is added to the `items` array, but the `List` doesn’t display the new item. I’ve tried adding `@Published` to the property and used `ObservableObject`, but that didn’t help. Also, I’ve ensured there are no issues with the identity of the items; I’ve even tried using `UUID` for unique identification. I've also checked the console for any errors, but there are none. The only behavior I notice is that the `List` seems to refresh correctly when I scroll or perform some other actions in the view, but it doesn't update when the data changes directly. Is there a specific way to force the `List` to refresh, or is there a different approach I should be taking? Any insights would be greatly appreciated! I'm working with Swift in a Docker container on CentOS. I'd love to hear your thoughts on this.
