如何在SwiftUI之间转换屏幕

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            // 主视图内容
        }
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                Text("主视图")
                    .font(.largeTitle)
                    .padding()
                
                NavigationLink(destination: SecondView()) {
                    Text("转到第二个视图")
                        .font(.title)
                        .padding()
                }
            }
            .navigationBarTitle("SwiftUI转换屏幕")
        }
    }
}

struct SecondView: View {
    var body: some View {
        VStack {
            Text("第二个视图")
                .font(.largeTitle)
                .padding()
            
            NavigationLink(destination: ThirdView()) {
                Text("转到第三个视图")
                    .font(.title)
                    .padding()
            }
        }
    }
}
