Data implementation guide in iOS 17 App with Combine and SwiftUI After Fetching from API
I'm learning this framework and I've encountered a strange issue with I'm working through a tutorial and Does anyone know how to I'm working on an iOS 17 app using SwiftUI and Combine, and I'm working with an scenario where the UI is not updating after fetching data from an API..... I implemented a simple ViewModel that uses a `@Published` property to hold the data, but after making the network request, the view does not refresh as expected. Here’s the relevant code snippet: ```swift import Combine import SwiftUI class MyViewModel: ObservableObject { @Published var items: [Item] = [] private var cancellables = Set<AnyCancellable>() func fetchItems() { let url = URL(string: "https://api.example.com/items")! URLSession.shared.dataTaskPublisher(for: url) .map { $0.data } .decode(type: [Item].self, decoder: JSONDecoder()) .replaceError(with: []) .receive(on: DispatchQueue.main) .assign(to: \.$items, on: self) .store(in: &cancellables) } } ``` In my SwiftUI view, I have: ```swift struct ContentView: View { @StateObject private var viewModel = MyViewModel() var body: some View { List(viewModel.items) { item in Text(item.name) } .onAppear { viewModel.fetchItems() } } } ``` I've verified that the network call returns data successfully, but I'm not seeing any updates in the list. I also tried adding print statements in the `fetchItems()` method to confirm that the data is correctly being assigned to `items`, and it is. I’ve checked whether my `Item` model conforms to `Decodable`, which it does. Additionally, I have ensured that the Combine framework is correctly imported, and I’m on the latest version of Xcode (15.0). Is there something I'm potentially missing in terms of SwiftUI's state management or Combine's data flow that could be preventing the UI from updating properly? Any feedback is welcome! I'm using Swift latest in this project. Thanks for any help you can provide! For reference, this is a production desktop app. For reference, this is a production microservice.
