如何观察SwiftUI中的文本或以其他方式将字符串传递给ViewModel？

@State private var text: String = ""

var body: some View {
    TextField("Enter text", text: $text)
        .onReceive(Just(text)) { newValue in
            // 在这里处理字符串变化
        }
}

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

struct ContentView: View {
    @ObservedObject var viewModel = ViewModel()

    var body: some View {
        TextField("Enter text", text: $viewModel.text)
            .onReceive(Just(viewModel.text)) { newValue in
                // 在这里处理字符串变化
            }
    }
}

struct ContentView: View {
    @State private var text: String = ""

    var body: some View {
        ChildView(text: $text)
    }
}

struct ChildView: View {
    @Binding var text: String

    var body: some View {
        TextField("Enter text", text: $text)
            .onReceive(Just(text)) { newValue in
                // 在这里处理字符串变化
            }
    }
}
