Updating Selection from Another View

[aralez-g0lem]

How I can updated selected State if I'm navigating to view (presented TabBar), but not from TabBar, like from button inside of another view, or using NavigationLink in another view.

Thank you

View with TabBar

struct GeneralView View {

    enum Item: Int, Tabbable {
        case home = 0
        case letters
        case heritage
        case bookmarks
        case third

        var icon: String {
            switch self {
                case .letters: return "textformat"
                case .heritage: return "command"
                case .home: return "house.fill"
                case .third: return "quote.bubble"
                case .bookmarks: return "bookmark.fill"

            }
        }

        var title: String {
            switch self {
                case .letters: return "Letters"
                case .heritage: return "Heritage"
                case .home: return "Arageel"
                case .third: return "Third"
                case .bookmarks: return "Bookmarks"

            }
        }
    }

    @State private var selection: Item = .home
    @State private var visibility: TabBarVisibility = .visible

    var body: some View {

        TabBar(selection: $selection, visibility: $visibility) {
            LettersGridView()
                .tabItem(for: Item.letters)

            HeritageZineHomeView()
                .environmentObject(RSSReader())
                .tabItem(for: Item.heritage)
            HomeView()
                .tabItem(for: Item.home)
            PBHomeView()
                .tabItem(for: Item.third)

            PBHomeView()
                .tabItem(for: Item.bookmarks)
        }
        .tabBar(style: CustomTabBarStyle())
        .tabItem(style: CustomTabItemStyle())
        .ignoresSafeArea(.all)
    }
}

Another View

    var stickyHeaderView: some View {
        HStack {
            Text("Heritage").modifier(MainStoryTitle(color: "BlackDark"))
            Spacer()
            NavigationLink (
                destination:
                    HeritageHomeView()
            ) {
                Image(systemName: "arrow.up.forward")
                    .foregroundColor(Color("Orange"))
            }
        }
        .padding(.horizontal, 30)

    }

Use a @Binding var selection: Item in Another View and pass it $selection. This will allow you to update the state.

Receiving error

Type 'Binding<Item>' has no member 'home'

that is just telling that you probably removed home from your enum or that it is taking some other Item type instead of your enum (the naming is very generic).

It would be something like this:

  struct GeneralView View {
    @State private var selection: Item = .home

    var body: some View {        
      ZStack {
          TabBar(selection: $selection, visibility: $visibility) {
          // ... some more code....
          }

         StickyHeaderView(selection: $selection)
      }
    }
    // ... some more code....

struct StickyHeaderView: View {
  @Binding var selection: Item

  var body: some View {
    Button("Selection to letters") {
                selection = .letters
            }
  }
