声明多个状态变量内联SwiftUI

import SwiftUI

struct ContentView: View {
    @State private var name: String = ""
    @State private var age: Int = 0
    @State private var isSubscribed: Bool = false

    var body: some View {
        VStack {
            TextField("Name", text: $name)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()

            Stepper(value: $age, in: 0...100) {
                Text("Age: \(age)")
            }
            .padding()

            Toggle("Subscribe", isOn: $isSubscribed)
                .padding()

            Text("Name: \(name)")
            Text("Age: \(age)")
            Text("Subscribed: \(isSubscribed ? "Yes" : "No")")
        }
    }
}

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