如何在SwiftUI中使一组按钮等宽

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Button Example")
                .font(.title)
            
            HStack {
                Button(action: {
                    // 按钮1的操作
                }) {
                    Text("Button 1")
                        .frame(maxWidth: .infinity)
                        .padding()
                        .background(Color.blue)
                        .foregroundColor(.white)
                        .cornerRadius(10)
                }
                
                Button(action: {
                    // 按钮2的操作
                }) {
                    Text("Button 2")
                        .frame(maxWidth: .infinity)
                        .padding()
                        .background(Color.green)
                        .foregroundColor(.white)
                        .cornerRadius(10)
                }
                
                Button(action: {
                    // 按钮3的操作
                }) {
                    Text("Button 3")
                        .frame(maxWidth: .infinity)
                        .padding()
                        .background(Color.orange)
                        .foregroundColor(.white)
                        .cornerRadius(10)
                }
            }
            .padding()
            
            Spacer()
        }
    }
}

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