在SwiftUI中，如何删除停留在键盘顶部的视图

import SwiftUI

struct ContentView: View {
    @State private var isKeyboardVisible = false
    
    var body: some View {
        GeometryReader { geometry in
            VStack {
                // Your other content here
                
                if isKeyboardVisible {
                    // View to be hidden when keyboard is visible
                    Text("Hidden View")
                        .opacity(0)
                }
            }
            .onAppear {
                NotificationCenter.default.addObserver(forName: UIResponder.keyboardWillShowNotification, object: nil, queue: .main) { notification in
                    isKeyboardVisible = true
                }
            }
            .onDisappear {
                NotificationCenter.default.addObserver(forName: UIResponder.keyboardWillHideNotification, object: nil, queue: .main) { notification in
                    isKeyboardVisible = false
                }
            }
        }
    }
}
