So you want to use NavigationView and NavigationLink instead of a button.

struct ContentView: View {
  @State var name: String = "Tim"

  var body: some View {
    NavigationView {
      VStack {
        TextField("Enter your name", text: $name)
        Text("Hello, \(name)!")
        NavigationLink(destination: SecondView(name: self.$name)){
        Text("LogIn")
       }
    }
  }
}

//Second ContenView

struct SecondView: View {
 @Binding var name: String
  var  body: some View {
   Text("Hello \(text)")
  }
 }

Passing Data Between Views in SwiftUI | by Filemon Salas, In the following example, we are going to pass a String from ContentView . to SecondView . SwiftUI has a preference system that enables us to pass key-value pairs up the view hierarchy. The process is next: Implement custom PreferenceKey, which is a named value produced by a view. In a child view, attach a key-value pair. In a parent view, attach a callback that keeps track of changes to this preference.


You can display print name either on the console or can display name in an alert. In the below snippet, to fetch name entered in text field on button click requires state variable instead of normal variable. It is created with @State keyword. State parameter manages the state in the View. So whenever there is change in state all the components that are associated with the state will be rendered again.

import SwiftUI

struct LoginUI: View {
    @State var textName: String = ""
    @State var showAlert = false

    var body: some View {

        VStack(alignment: .center, spacing: 2.0) {
            TextField("Enter your name", text: $textName).padding(10)

              Button(action: {
                print("Entered name is \(self.textName)")
                self.showAlert = true

              }, label: {Text("Login")}).padding().background(Color.gray)
        }
        .padding(5.0)
        .alert(isPresented: $showAlert) {
            Alert(title: Text("Entered name is"), message: Text("\(self.textName)"))
    }
    }
}

struct LoginUI_Previews: PreviewProvider {
    static var previews: some View {
        LoginUI()
    }
}
