SwiftUI @State not triggering re-render on nested ObservableObject changes
I recently switched to I'm sure I'm missing something obvious here, but I'm experiencing an issue where changes to an `ObservableObject` that is nested within a view don't trigger a re-render of the parent view in SwiftUI..... I've defined a `@State` property in my parent view and am observing changes in a child view that updates an `@Published` property on an `ObservableObject`. However, the parent view doesn't refresh when the child updates its state. Here's a simplified version of what I have: ```swift import SwiftUI import Combine class ChildModel: ObservableObject { @Published var value: String = "" } struct ChildView: View { @ObservedObject var model: ChildModel var body: some View { TextField("Enter value", text: $model.value) .padding() } } struct ParentView: View { @State private var title: String = "Initial Title" @StateObject private var childModel = ChildModel() var body: some View { VStack { Text(title) .font(.largeTitle) ChildView(model: childModel) Button("Change Child Value") { childModel.value = "New Value" title = "Title Updated" } } .padding() } } struct ContentView: View { var body: some View { ParentView() } } ``` When I run this code and change the value in the `TextField`, the title does not update even though I also change the title in the same button action. The `ParentView` isn't responding to changes in `ChildModel`. I tried using `@StateObject` instead of `@ObservedObject` and vice versa, but it doesn't seem to make any difference. I’ve also ensured that the `@Published` property in the `ChildModel` is properly set up. Is there something I am missing regarding how `ObservableObject` and `@State` work together? Am I using the right properties in the right places? This is on Xcode 14 with iOS 16. Any insights would be greatly appreciated! This is part of a larger application I'm building. What's the best practice here? What's the best practice here? I'm using Swift 3.9 in this project. Has anyone dealt with something similar?
