SwiftUI中相互链接的多个滑块

import SwiftUI

struct ContentView: View {
    @State private var redValue: Double = 0.5
    @State private var greenValue: Double = 0.5
    
    var body: some View {
        VStack {
            Slider(value: $redValue, in: 0...1, step: 0.01)
                .padding()
            
            Slider(value: $greenValue, in: 0...1, step: 0.01)
                .padding()
            
            Rectangle()
                .foregroundColor(Color(red: redValue, green: greenValue, blue: 0))
                .frame(width: 200, height: 200)
        }
    }
}

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