swiftui - 为什么在我什至在 SwiftUI 上单击它之前调用 NavigationLink

Question

为什么“init”打印了四次？

import SwiftUI 

struct HomeView: View {

    let items: [String] = [“aaa”, “bbb”]
    
    var body: some View {

        NavigationView {

            ScrollView {

                ForEach(colors, id: \.self) { color in

                            VStack {

                                NavigationLink(destination: StudentView()) {
                                        Image(systemName: "trash.fill")
                                            .resizable()
                                            .frame(width: 100, height: 100)

                                }

                            }

                }

             }


        }
    }
}

=================================================

import SwiftUI

struct StudentView: View {
        
    init() {
        print("init")
    }
    

    var body: some View {
            
            ScrollView {

                
            }      
    }
}
