NavigationLink (switch between views) in SwiftUI

There are many ways to interact with different screens (views), here I'll cover them all with examples and pictures. Simple and concise.

_{Updated for SwiftUI 2.0}

NavigationLink

Demo

We can do the above with the following code:

If you want to have the "Go Back" button removed, add  .navigationBarBackButtonHidden(true)

ContentView

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: SecondView()) {
                    Text("Second View")
                }
             }
            .hideNavigationBar()
        }
    }
}

SecondView

import SwiftUI

struct SecondView: View {
    var body: some View {
        VStack {
            Text("You are in View 2 ✅")
        }
        .navigationBarBackButtonHidden(true)
    }
}

Extension

import SwiftUI

struct HiddenNavigationBar: ViewModifier {
    init() {
        UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)
        UINavigationBar.appearance().shadowImage = UIImage()
    }
    
    func body(content: Content) -> some View {
        content
            .navigationBarTitle("Back", displayMode: .inline)
            .navigationBarHidden(true)
    }
}

extension View {
    func hideNavigationBar() -> some View {
        modifier( HiddenNavigationBar() )
    }
}
