Custom View Not Updating After State Change in iOS 17 with SwiftUI
I've spent hours debugging this and I'm a bit lost with I'm upgrading from an older version and I'm confused about I'm working on a SwiftUI app where I have a custom view that displays a list of items... The view is supposed to update when the data changes, but I find that it does not reflect the new state after an update. My view model conforms to `ObservableObject`, and I’m using `@Published` to mark the property that should trigger the view refresh. Here's a simplified version of my code: ```swift import SwiftUI import Combine class ItemViewModel: ObservableObject { @Published var items: [String] = [] func addItem(_ item: String) { items.append(item) } } struct ItemListView: View { @ObservedObject var viewModel: ItemViewModel var body: some View { VStack { List(viewModel.items, id: \.self) { item in Text(item) } Button("Add Item") { viewModel.addItem("New Item") } } } } struct ContentView: View { @StateObject var viewModel = ItemViewModel() var body: some View { ItemListView(viewModel: viewModel) } } ``` When I tap the 'Add Item' button, I expect to see the new item appear in the list, but it only updates after I navigate away and then return to the view. I’ve checked that the `viewModel` is correctly instantiated as a `@StateObject`, and I'm using `@ObservedObject` in the `ItemListView`. I've also confirmed that the `addItem` function is being called by adding a print statement. The print confirms that the item is added, but the UI remains the same. I've tried forcing a refresh by calling `objectWillChange.send()` before updating the items array, but that didn't resolve the issue either. Any insights into why my custom view isn't updating in real time? Is there something I'm missing with the state management in SwiftUI 17? For reference, this is a production application. Could someone point me to the right documentation? I'm working with Swift in a Docker container on Windows 10. Thanks for your help in advance! This is happening in both development and production on Ubuntu 22.04. I appreciate any insights!
