从列表中选择多个项目并在SwiftUI中更改其颜色

import SwiftUI

struct ContentView: View {
    @State private var color: Color = .blue

    let projects = ["Project 1", "Project 2", "Project 3"]

    var body: some View {
        VStack {
            ForEach(projects, id: \.self) { project in
                Text(project)
                    .padding()
                    .background(color)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
            
            Button(action: {
                color = .red
            }) {
                Text("Change Color")
                    .padding()
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
        }
        .padding()
    }
}

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