    var body: some View {
        HStack(spacing: -5) {
            ForEach(TabBarItems.allCases, id: \.self) { item in   //  instead of a item TabBarItems.allCases
                Button(action: action) {
                    VStack {
                        item.icon

                    }

                .foregroundColor(Color.white)
            }
        }
        .padding(.bottom, 20)
        .padding(.top, 10)
        .padding(.horizontal, 5)
        .background(Color.customGrey)
    }
}
struct MainView: View {

    @ObservedObject var MainVM: MainViewModel = MainViewModel()

    var body: some View {
        ZStack {
            Color.clear.background(Color.white)
                .edgesIgnoringSafeArea(.all)
            VStack {
                Header(title: "Будь в теме")
                Spacer()
                CustomTabBar(action: { ??? })   // toggle menu
            }
            .edgesIgnoringSafeArea(.bottom)
