SwiftUI TabbedView only shows first tab's cont

Question

I'm trying to build a TabbedView with the following simple code:

TabbedView {
    Text("Hello world")
        .tabItemLabel(Text("Hello"))
    Text("Foo bar")
        .tabItemLabel(Text("Foo"))
}

When running, both tabs are visible and enabled but the second tab's ("Foo") content is blank.

Answer 1

I was able to fix this by adding a selection state variable and passing that in for the selection:

struct ContentView : View {
    @State private var selection = 1

    var body: some View {
        TabbedView(selection: $selection) {
            Text("Tab 1!").tabItemLabel(
                Text("Tab 1")).tag(1)
            Text("Tab 2!").tabItemLabel(Text("Tab 2")).tag(2)
        }
    }
}

Now, tapping "Tab 2" will show "Tab 2!" on the screen, as opposed to a blank screen.

This was using Xcode 11.0 beta 2 (11M337n), macOS Catalina 10.15 Beta (19A487l).

In the newest version you should use TabView:

   TabView {
        AnyView()
            .tabItem {
                Text("Label 1")
            }
        AnyView()
            .tabItem {
                Text("Label 2")
            }
    }

//Try this way, but you can't use an icon from SF Symbols, use the icons from //icons8.com struct ContentView: View {

var body: some View{

TabbedView { Living_R()

                        .tabItemLabel(VStack {
                            Image("home")
                            Text("Home")
                          }).tag(0)

                    ContentView()
                        .tabItemLabel(VStack {
                            Image("search")
                            Text("Search")
                        }).tag(1)

                        Text("Info")
                        .tabItemLabel(VStack {
                            Image("page")
                            Text("Doc")
                        }).tag(2)

        }
      }    
    }

Answer 5

Try adding tags:

    TabbedView {
        Text("Hello world")
            .tabItem { Text("Hello") }
            .tag(0)
        Text("Foo bar")
            .tabItem { Text("Foo") }
            .tag(1)
    }

Answer 6

In Xcode GM, TabbedView was renamed to TabView. So here's the right way to create a tab bar in SwiftUI now:

  TabView {
        Text("Hello world")
            .tabItem { Text("Hello") }
            .tag(0)
        Text("Foo bar")
            .tabItem { Text("Foo") }
            .tag(1)
    }
