How to call swiftui struct from function

Question

The HomeView()struct is not able to call in function or in button action. How should i call the HomeView() struct from another struct. While calling HomeView() either in button action or function of LoginView() , am getting "Result of 'HomeView' initializer is unused"

struct LoginView: View
{
    var body: some View
    {
    }
    func login()
    {
        HomeView() //Result of 'HomeView' initializer is unused "WARNING"
    }
}



struct LoginView: View
{
    var body: some View {
        NavigationView {
            VStack
                {
                    Button(action: {
                        HomeView() //Result of 'HomeView' initializer is unused  "WARNING"
                    })
                    {
                        HStack(alignment: .center) {
                            Spacer()
                            Text("Submit")
                        }
                    }
            }
        }
    }
}



struct HomeView: View
{
    var body: some View
    {
    }
    func submit()
    {
    }
}

HomeView() is not a function, it is constructor of value, like let view = HomeView() — Asperi

What do you mean by « call a struct » ? You don’t call structs. You create them, mutate them and copy them but I don’t know what you mean by calling a struct. — Damiaan Dufaux

To present another view via button, please check below:

struct LoginView: View {
    @State var showingHome = false
    var loginButton: some View {
        Button(action: {
            self.showingHome.toggle()
        }) {
            Text("Login")
            .foregroundColor(Color.init(.white))
            .font(.system(size: 14))
            .frame(minWidth: 0, maxWidth: .infinity)
            .padding()
            .background(Color.init(.systemOrange))
            .cornerRadius(4)
        }
    }

    var body: some View {
        NavigationView {
            VStack{
                loginButton.sheet(isPresented: $showingHome) {
                    HomeView()
                }
            }
        }
    }
}

The user can dismiss if we present using sheet. i wanted to navigate between swiftui views

AnyView({ () -> AnyView in if user logged in { return AnyView(HomeView()) } else { return AnyView(LoginView()) } }

After a user logs in or already logged in, it will present the HomeView() otherwise it presents LoginView(). If this is what you wanted
