如何在SwiftUI中始终显示键盘

import Combine
import UIKit

struct ContentView: View {
    @State private var isKeyboardVisible = false
    
    var body: some View {
        VStack {
            // Your content here
            
            Spacer()
            
            Text("Keyboard is \(isKeyboardVisible ? "Visible" : "Hidden")")
        }
        .onReceive(NotificationCenter.default.publisher(for: UIResponder.keyboardWillShowNotification)) { _ in
            self.isKeyboardVisible = true
        }
        .onReceive(NotificationCenter.default.publisher(for: UIResponder.keyboardWillHideNotification)) { _ in
            self.isKeyboardVisible = false
        }
    }
}
