如何在SwiftUI中关闭viewModel中的视图？

class ViewModel: ObservableObject {
    @Published var isViewShown = false
}

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

    var body: some View {
        VStack {
            if viewModel.isViewShown {
                Text("Hello, World!")
            }
            Button("Show View") {
                viewModel.isViewShown = true
            }
        }
    }
}

class ViewModel: ObservableObject {
    @Published var isViewShown = false
}

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

    var body: some View {
        VStack {
            if viewModel.isViewShown {
                Text("Hello, World!")
            }
            Button("Show View") {
                viewModel.isViewShown.toggle()
            }
            AnotherView(isViewShown: $viewModel.isViewShown)
        }
    }
}

struct AnotherView: View {
    @Binding var isViewShown: Bool

    var body: some View {
        // 可以在此处使用isViewShown变量进行其他操作
        EmptyView()
    }
}
