How to present a view full-screen in SwiftUI?

Question

I worked to a login view, now I want to present the view after login, but I do not want the user to have the possibility to return to the login

Answer 1

Encapsulate the body in a Group to eliminate compiler errors:

struct StartView: View {

@EnvironmentObject var userAuth: UserAuth

var body: some View {
    Group {
        if userAuth.isLoggedin {
            AppView()
        } else {
            LoginView()
        }

    }
}
