如何在Swiftui中将键盘颜色更改为深色

import SwiftUI

struct KeyboardColorModifier: UIViewRepresentable {
    var color: UIColor
    
    func makeUIView(context: Context) -> UIView {
        let view = UIView()
        return view
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        let keyboard = UIInputView(frame: CGRect(x: 0, y: 0, width: 0, height: 0), inputViewStyle: .keyboard)
        keyboard.backgroundColor = color
        uiView.addSubview(keyboard)
    }
}

import SwiftUI

struct ContentView: View {
    @State private var text: String = ""
    
    var body: some View {
        VStack {
            TextField("Enter text", text: $text)
                .padding()
                .background(Color.gray)
                .cornerRadius(10)
                .padding()
                .keyboardType(.default)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .modifier(KeyboardColorModifier(color: .darkGray))
        }
    }
}
