SwiftUIでの画面遷移4

SwiftUIでの画面遷移4

NavigationLinkで遷移先を複数にするとどうなるかです。

親Viewでのコード

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            NavigationView {
                NavigationLink(destination: SecondView()) {
                    Text("二つ目画面")
                        .frame(height: 50)
                }
            }
            NavigationView {
                NavigationLink(destination: ThirdView()) {
                    Text("三つ目画面")
                        .frame(height: 50)
                }
            }

        }
    }
}

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

子View1

import SwiftUI

struct SecondView: View {
    var body: some View {
        GeometryReader { geometory in
           VStack {
                Text("二画面目")
            }
           .frame(width: geometory.size.width,
                height: geometory.size.height)
            .background(Color.cyan)
        }
    }    
}

struct SecondView_Previews: PreviewProvider {
    static var previews: some View {
        SecondView()
    }
}

子View2

import SwiftUI

struct ThirdView: View {
    var body: some View {
        GeometryReader { geometory in
           VStack {
                Text("三画面目")
            }
           .frame(width: geometory.size.width,
                height: geometory.size.height)
            .background(Color.blue)
            .foregroundColor(Color.white)
        }
    }
}

struct ThirdView_Previews: PreviewProvider {
    static var previews: some View {
        ThirdView()
    }
}
