After following instructions from https://blckbirds.com/post/how-to-navigate-between-views-in-swiftui-by-using-an-environmentobject/#

My files have crashed. It won't let me preview it. When I run the simulator, it's giving me an error saying no observableobject of type Profile found. That should be in my class in the ContentView.

I have two environmentobjects and two observableobjects. One in the class in my contentview and one in the ViewRouter swift file. Could this be why it's crashing?

I already have the ContentView as my "page1"

I created two other view files. One is the SallyView file, which is going to be the parent view that will show "page1" first. And the other one is called SecondView.

I already have an environmentobject in my class in the ContentView that I use to access a variable from a textfield. But I had to create another observableobject in ViewRouter swift file which has the following code below. I wonder if this is the reason for the crash.

import Foundation
import Combine
import SwiftUI

class ViewRouter: ObservableObject {

    let objectWillChange = PassthroughSubject<ViewRouter,Never>()

    var currentPage: String = "page1" {
        didSet {
            withAnimation() {
                objectWillChange.send(self)
            }
        }
    }
}

The scene delegate looks like this one below.

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

    if let windowScene = scene as? UIWindowScene {
        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = UIHostingController(rootView: SallyView().environmentObject(ViewRouter()))
        self.window = window
        window.makeKeyAndVisible()
    }
}

My ContentView is below.

class Profile: ObservableObject { @Published var name = ""

convenience init (name: String) {
    self.init()
    self.name = name
}

} struct ContentView: View { @EnvironmentObject var viewRouter: ViewRouter @EnvironmentObject var profile: Profile

var body: some View {
//my other codes are here as well
VStack {
    Button(action: {self.viewRouter.currentPage = "page2"}) {
        NextButtonContent()
    }
}

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

} struct NextButtonContent : View { var body: some View { return Text("Next") .foregroundColor(.white) .frame(width: 200, height: 50) .background(Color.blue) .cornerRadius(15) .padding(.top, 50) } } My parentview is SallyView like below

import SwiftUI

struct SallyView: View {

@EnvironmentObject var viewRouter: ViewRouter

var body: some View {
    VStack {
                if viewRouter.currentPage == "page1" {
                    ContentView()
                } else if viewRouter.currentPage == "page2" {
                    SecondView()
                        .transition(.scale)
                }
            }
        }
    }

struct SallyView_Previews: PreviewProvider { static var previews: some View { SallyView().environmentObject(ViewRouter()) } }

Thank you for your response. It actually worked!
