swift swiftui observableobject

I've been banging my head against this for hours... I've looked through the documentation and I'm still confused about After trying multiple solutions online, I still can't figure this out..... I'm facing an issue where my SwiftUI view isn't updating as expected after modifying a property marked with @Published in my ViewModel. I'm using Swift 5.7 and Xcode 15, and I have a simple app structure where my ViewModel conforms to ObservableObject. Here's a snippet of my ViewModel: ```swift import SwiftUI import Combine class MyViewModel: ObservableObject { @Published var count: Int = 0 func incrementCount() { count += 1 } } ``` In my View, I have something like this: ```swift struct ContentView: View { @StateObject private var viewModel = MyViewModel() var body: some View { VStack { Text("Count: \(viewModel.count)") .font(.largeTitle) Button("Increment") { viewModel.incrementCount() } } } } ``` However, when I tap the "Increment" button, the count displayed on the screen does not update. I've confirmed that the `incrementCount()` function is being called because I added a print statement, and it outputs the expected values. The view renders correctly on the first load, but it seems to ignore updates after the state change. I've tried using `@ObservedObject` instead of `@StateObject`, but that led to an even more inconsistent state. I also ensured that my `ContentView` is not being recreated on each button tap. This behavior is particularly puzzling since I'm following what I thought were the best practices for SwiftUI and Combine. Is there something I might be missing here? Any insights or potential fixes would be greatly appreciated! My development environment is Ubuntu. How would you solve this? This is part of a larger web app I'm building. Any ideas what could be causing this? The project is a desktop app built with Swift. Is there a simpler solution I'm overlooking?
