swiftui state binding swift

I can't seem to get I'm refactoring my project and I'm trying to update a `@State` variable from a custom view in SwiftUI, but I'm running into problems getting the value to reflect in the parent view. I have a parent view that contains a `@State` variable, and I want to modify that state from a button inside a custom child view. Here's a simplified version of my setup: ```swift struct ParentView: View { @State private var count: Int = 0 var body: some View { VStack { Text("Count: \(count)") .font(.largeTitle) CustomButtonView(count: $count) } } } struct CustomButtonView: View { @Binding var count: Int var body: some View { Button(action: { count += 1 }) { Text("Increment") } } } ``` When I press the button in `CustomButtonView`, the `count` variable in `ParentView` doesn't update as expected. I expected to see the text display the updated count, but it remains at its initial value. I added print statements to check if the button's action is being called, and it is, yet the `count` variable does not change in the parent view. I've ensured that I am passing the `count` variable as a `Binding`, but I still see no updates in the UI. I also checked if there are any issues with state management, and everything seems fine. Is there something I'm missing here? This scenario continues even after cleaning the build folder and restarting Xcode, which is running on version 15.0. Any insights would be appreciated! Is there a simpler solution I'm overlooking?
