swift firebase swiftui firestore

I can't seem to get I'm following best practices but I'm relatively new to this, so bear with me..... I'm currently working with an scenario with integrating Firebase Firestore in my SwiftUI app. Despite setting everything up correctly, the data from my Firestore collection isn't displaying in the SwiftUI view. I've implemented a simple model for retrieving the data, but the view remains empty. Here's what I've tried: I have the following model to fetch data: ```swift import FirebaseFirestore import FirebaseFirestoreSwift struct Item: Identifiable, Codable { @DocumentID var id: String? var title: String } class FirestoreViewModel: ObservableObject { @Published var items = [Item]() private var db = Firestore.firestore() func fetchItems() { db.collection("items").getDocuments() { (querySnapshot, behavior) in if let behavior = behavior { print("behavior getting documents: \(behavior)") } else { self.items = querySnapshot?.documents.compactMap { try? $0.data(as: Item.self) } ?? [] } } } } ``` In my SwiftUI view, I have: ```swift struct ContentView: View { @StateObject var viewModel = FirestoreViewModel() var body: some View { List(viewModel.items) { item in Text(item.title) } .onAppear() { viewModel.fetchItems() } } } ``` I also checked if my Firestore rules allow read access. The console shows "Access denied" when I try to fetch data, despite being logged in. I've verified that my Firebase configuration is in place, the plist file is included, and I am using the correct collection name. I also tried to call `viewModel.fetchItems()` in the `init()` method of `FirestoreViewModel`, but it didn't change the outcome. Any insights on what might be going wrong or how to debug this further? I would appreciate any advice on best practices for ensuring data displays correctly in SwiftUI with Firestore. This is part of a larger API I'm building. I'd really appreciate any guidance on this. Is there a simpler solution I'm overlooking?
