Ich habe eine Wrapper-Ansicht erstellt, um die richtige Bindungsunterstützung für Vorschauen zu ermöglichen. Der Grund, warum die Verwendung eines @State innerhalb der Vorschau nicht funktioniert, ist, dass die Eigenschaft “previews” von der Laufzeit nicht als “Body”-Methode betrachtet wird und @State sich beschwert, wenn Sie versuchen, Bindungen außerhalb eines Body-Methodenaufrufs zu erhalten (es ruft fatalError() auf).
