SwiftUI @FocusState when view appears

How can I focus on a specific text field when the view appears? I have a basic form where I want the title field is be focused when the modal displays. I have the following code which achieves this but there has to be a cleaner/better way. Can I set the initial value of a @FocusState var to a field or a boolean that then selects the text field when the view appears?

var body: some View {
        NavigationView {
            VStack {
                Form {
                    TextField("Title", text: $viewModel.title)
                        .focused($titleIsFocused)
                }
            }
            .navigationBarTitle("New List")
            .onAppear {
                DispatchQueue.main.asyncAfter(deadline: .now() + 0.6) {
                    titleIsFocused = true
                }
            }
        }
    }
}
