SwiftUI: how to to Bind to StateObject in Nested View on iOS 16
I just started working with I'm stuck on something that should probably be simple... I'm working on a project and hit a roadblock. I'm working with an scenario with data binding in a SwiftUI application where I have a nested view structure that uses a `@StateObject`. The parent view is supposed to pass a state object down to a child view, but it seems that changes made in the child view are not reflecting back in the parent. I have the following setup: ```swift class MyModel: ObservableObject { @Published var value: String = "" } struct ParentView: View { @StateObject private var model = MyModel() var body: some View { VStack { Text("Value: \(model.value)") ChildView(model: model) } } } struct ChildView: View { @ObservedObject var model: MyModel var body: some View { Button("Update Value") { model.value = "Updated!" } } } ``` When I tap the button in the `ChildView`, I expect the text in the `ParentView` to update accordingly. However, it does not change, and I get the following behavior in the console: ``` Invalidating view while updating! Ensure that you're not mutating state during the view update cycle. ``` I've tried using `@ObservedObject` in the `ChildView`, but it still does not reflect the changes in the `ParentView`. I also checked that my model class conforms to `ObservableObject` and that the properties are marked as `@Published`. This scenario only occurs on iOS 16 and not on earlier versions. Any suggestions on how to troubleshoot this binding scenario? My development environment is macOS. I'm working on a API that needs to handle this. Am I missing something obvious? What are your experiences with this? Any suggestions would be helpful.
