如何将我的SwiftUI视图的@状态交换为我的视图模型@发布的变量？

import SwiftUI
import Combine

class ViewModel: ObservableObject {
    @Published var myVariable: String = ""
}

struct ContentView: View {
    @State private var myVariable: String = ""
    @ObservedObject var viewModel = ViewModel()

    var body: some View {
        VStack {
            TextField("Enter text", text: $myVariable)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()

            Button(action: {
                viewModel.myVariable = myVariable
            }) {
                Text("Update ViewModel")
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView().environmentObject(ViewModel())
    }
}
