SwiftUI ObservableObject List iOS 17 Swift

This might be a silly question, but I'm building a feature where I'm sure I'm missing something obvious here, but I'm working with an scenario where my SwiftUI List doesn't seem to reflect changes made to the `@ObservedObject` that it relies on..... I'm working on a simple task manager app where I have a `TaskStore` class, which conforms to `ObservableObject`. The `tasks` property is an array of `Task` objects, and I'm trying to update this list when a new task is added. However, even after adding a new task, the List doesn't refresh. Here's the relevant part of my code: ```swift import SwiftUI import Combine class Task: Identifiable, ObservableObject { let id = UUID() @Published var title: String init(title: String) { self.title = title } } class TaskStore: ObservableObject { @Published var tasks: [Task] = [] func addTask(title: String) { let newTask = Task(title: title) tasks.append(newTask) // This should trigger a UI update, right? } } struct TaskListView: View { @ObservedObject var taskStore: TaskStore var body: some View { List(taskStore.tasks) { task in Text(task.title) } .navigationBarItems(trailing: Button(action: { taskStore.addTask(title: "New Task") }) { Text("Add Task") }) } } ``` I've ensured that `TaskStore` is properly initialized and passed into `TaskListView`, but when I tap the "Add Task" button, the new task is not displayed in the List. Additionally, I'm not seeing any errors in the console, which makes debugging a bit tricky. I've tried using `@StateObject` in the `TaskListView` instead of `@ObservedObject`, but that resulted in more issues with the task store not being retained. Any insights on what might be going wrong here? Is there a common pitfall with `@ObservedObject` in SwiftUI that I'm missing? Any help would be greatly appreciated! Has anyone else encountered this? I'm open to any suggestions.
