    var body: some View {
        VStack{
            VStack{
                ZStack{
                    Color.gg.ignoresSafeArea().frame(width: 400,height: 250)
                    
                    Spacer()
                    
                    Spacer()
                    Image("logo")
                        .resizable()
                        .aspectRatio(contentMode: .fill)
                        .frame(width: 180, height: 100)
                        .padding()

                        .font(.system(size: 30))
                        .foregroundColor(.blue)

                    Spacer()
                    
                        // Text(profile.username)
                        .font(.title)
                        .bold()
                    Spacer()
                }
            }

                        .font(.body)
                        .padding()
                    Text("Username:")
                 //   Text(profile.username)
                            .font(.body)
                            .padding()
                    Button(action: {
//                        logout()
