I have a textfield that I want to use to track tasks with in a MacOS App. As the placeholder, I would like to see the currently active task. This means, I have to update the placeholder when the Task changes. When there is text in the Textfield when that happens, it works fine but when the Textfield is empty and I change the placeholder, I get the warning Modifying state during view update, this will cause undefined behavior. Now my main question is, is what I am doing not intended / bad practice or is that an oversight in SwiftUI? Here is a code example for reproduction, I used the structure with two files because that's what caused the behaviour in my App. The view making the changes one level above: struct ContentView: View {     @State var placeholder: String = "Test"     var body: some View {         VStack {             SubView(placeholder: placeholder)             Button("UpdatePlaceholder") {                 placeholder = placeholder == "Test" ? "Blub" : "Test"             }         }     } } The subview that has the textfield with placeholder: struct SubView: View {     @State var currentText: String = ""     let placeholder: String     var body: some View {         TextField(placeholder, text: $currentText)     } } I'm on Xcode 13.3.1 and MacOS 12.3.1
