Navigation Link - Swift UI iOS 16

#swift #ios #xcode #swiftui

Ever been using NavigationLink inside a NavigationView and got this deprecation warning in Xcode?

Here's how to fix it!

Before

Let's start with an iOS15 example of a NavigationView with a .stack NavigationViewStyle, and a NavigationLink which links to SecondView when the button is pressed.

import SwiftUI

struct ContentView: View {
    @State var showSecondView: Bool = false
    var body: some View {
        NavigationView {
            VStack {
                Button {
                    showSecondView.toggle()
                } label: {
                    Text("Show Second View")
                }
                NavigationLink(
                    destination: SecondView(),
                    isActive: $showSecondView
                ) {
                    EmptyView()
                }
            }
        }
        .navigationViewStyle(.stack)
    }
}

struct SecondView: View {
    var body: some View {
        VStack {
            Text("Hello! I'm the second View")
        }
    }
}

After

To update for iOS 16 and remove the deprecation warning we can:

Change NavigationView to NavigationStack
Change NavigationLink to navigationDestination
Remove .navigationViewStyle(.stack)

struct ContentView: View {
    @State var showSecondView: Bool = false
    var body: some View {
        NavigationStack {
            VStack {
                Button {
                    showSecondView.toggle()
                } label: {
                    Text("Show Second View")
                }
                .navigationDestination(
                 isPresented: $showSecondView) {
                     SecondView()
                 }
            }
        }
    }
}
