Go to a new view using SwiftUI

This was not intended to be the top answer here - but rather an alternative method if you didn't want the navigation bar. See Jake's answer below for the normal way to do this with NavigationView & NavigationLink. Hopefully this is still useful or points you in the right direction too.

If you are just trying to get a NavigationLink working with a Binding, you can use the same NavigationLink init I did with the isActive binding parameter.

^{Anyway, back to the answer…}

I made a view modifier for this. It also means that there is no navigation bar. You can call it like so:

.navigate(to: MainPageView(), when: $willMoveToNextScreen)

This can be attached to anything, so I typically attach it to the end of the body, for example:

@State private var willMoveToNextScreen = false

var body: some View {
    VStack {
        /* ... */
    }
    .navigate(to: MainPageView(), when: $willMoveToNextScreen)
}

Code (remember to import SwiftUI):

extension View {
    /// Navigate to a new view.
    /// - Parameters:
    ///   - view: View to navigate to.
    ///   - binding: Only navigates when this condition is `true`.
    func navigate<NewView: View>(to view: NewView, when binding: Binding<Bool>) -> some View {
        NavigationView {
            ZStack {
                self
                    .navigationBarTitle("")
                    .navigationBarHidden(true)

                NavigationLink(
                    destination: view
                        .navigationBarTitle("")
                        .navigationBarHidden(true),
                    isActive: binding
                ) {
                    EmptyView()
                }
            }
        }
        .navigationViewStyle(.stack)
    }
}

The key is to use a NavigationView and a NavigationLink:

import SwiftUI

struct ContentView : View {
    var body: some View {
        NavigationView {
            VStack {
                Text("Hello World")
                NavigationLink(destination: DetailView()) {
                    Text("Do Something")
                }
            }
        }
    }
}

Here's another way to present a view WITHOUT using NavigationView. This is like UIKit's UIModalPresentationStyle.currentContext.

struct PresenterButtonView: View {
var body: some View {
    PresentationButton(Text("Tap to present"),
                       destination: Text("Hello world"))
}}

if don't want to show the navigationView you can hide it in destination.

struct ContentViewA : View {
    var body: some View {
        NavigationView {
            VStack {
                Text("Hello World")
                NavigationLink(destination: ContentViewB()) {
                    Text("Go To Next Step")
                }
            }
        }
    }
}



struct ContentViewB : View {
        var body: some View {
            NavigationView {
                VStack {
                    Text("Hello World B")

                }.navigationBarTitle("")
                .navigationBarHidden(true)
            }
        }
    }

or if you want to hide it based on conditions you can use @State for changing the visibility.
