struct ContentView: View {
    var body: some View {
        TabView {
            Text("Page 1")
                .tabItem {
                    Image(systemName: "1.circle")
                    Text("Page 1")
                }
            
            Text("Page 2")
                .tabItem {
                    Image(systemName: "2.circle")
                    Text("Page 2")
                }
            
            Text("Page 3")
                .tabItem {
                    Image(systemName: "3.circle")
                    Text("Page 3")
                }
        }
        .tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
    }
}
