使用带有TextField的.alert(isPresented)作为输入的SwiftUI？

import SwiftUI

struct ContentView: View {
    @State private var isShowingAlert = false
    @State private var inputText = ""

    var body: some View {
        VStack {
            Button("Show Alert") {
                isShowingAlert = true
            }
        }
        .alert(isPresented: $isShowingAlert) {
            Alert(
                title: Text("Input Text"),
                message: TextField("Enter text", text: $inputText),
                primaryButton: .default(Text("OK")),
                secondaryButton: .cancel()
            )
        }
    }
}

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