Answer 1

You can no longer use NavigationButton. Instead you should use NavigationLink.

struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationLink(destination: DetailView()) {
                Text("Push new screen")
            }
        }
    }
}

I think this is the easiest and clear way. Use fullScreenCover after UI tool.

Button(action: {
         //code
         }){
           Text("Send")
         }.fullScreenCover(isPresented: self.$model.goToOtherView, content: {
                    OtherView()
                })

Answer 3

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"))
}}

Now we can use NavigationLink

---

File A:

struct ContentView: View {
var body: some View {
    NavigationView {
        VStack {
            Text("Hello World")
            NavigationLink(destination: secondView()) {
                Text("Hit Me!")
                    .fontWeight(.semibold)
                    .font(.title)
                    .padding()
                    .foregroundColor(.white)
                    .background(LinearGradient(gradient: Gradient(colors: [Color(.white),Color(.blue)]), startPoint: .leading, endPoint: .trailing))
                    .cornerRadius(40)
        }
      }
    }
  }
}

File B:

struct secondView: View {
var body: some View {
    VStack {
    VStack(alignment: .leading) {
        Text("Turtle Rock")
            .font(.title)
        HStack(alignment: .top) {
            Text("Joshua Tree National Park")
                .font(.subheadline)
            Spacer()
            Text("California")
                .font(.subheadline)
        }
    }
    .padding()
        Spacer()

    }
  }
}                                                                                                  

Answer 5

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.

Have to create a DetailView like LandmarkDetail() and call a NavigationButton with destination as LandmarkDetail(). Now detail view was open.

For passing values to detail screen means. by sending like below code.

struct LandmarkList: View {
    var body: some View {
        NavigationView {
            List(landmarkData) { landmark in
                NavigationButton(destination: LandmarkDetail()) {
                    LandmarkRow(landmark: landmark)
                }
            }
            .navigationBarTitle(Text("Landmarks"))
        }
    }
}
