You would use a TabView {...}<\/code> to accomplish this. Effectively you instantiate your views inside of the TabView<\/code> then add an item modifier to each view.<\/p>\n

var body: some View {\n    TabView {\n        Text(\"A\")\n            .tabItem { Text(\"A\") }\n        Text(\"B\")\n            .tabItem { Text(\"B\") }\n        Text(\"C\")\n            .tabItem { Text(\"C\") }\n    }\n\n\n    init() {\n        UITabBar.appearance().backgroundColor = UIColor.red\n    }\n}\n<\/code><\/pre>\n
What this code does: https:\/\/i.stack.imgur.com\/CKBHm.gif<\/a><\/p>\n
For added clarity, you can add any item you want to a TabView. It basically acts as a container for the views that you add.<\/p>\n
struct ContentView: View {\n    var body: some View {\n        TabView {\n            FirstView()\n                .tabItem { Text(\"A\") }\n            SecondView()\n                .tabItem { Text(\"B\") }\n            ThirdView()\n                .tabItem { Text(\"C\") }\n        }\n    }\n}\n\nstruct FirstView: View {\n    var body: some View {\n        Text(\"A\")\n    }\n}\n\nstruct SecondView: View {\n    var body: some View {\n        Text(\"B\")\n    }\n}\n\nstruct ThirdView: View {\n    var body: some View {\n        Text(\"C\")\n    }\n}\n<\/code><\/pre>\n
Custom Tab Bar<\/h2>\n
This is a very simple case where we simply swap out the parent VStack{}<\/code> based on the enum that we created. When it’s first initialized this would set the .first<\/code> page and that would be the one displayed. Anytime we change it with a button action located in the HStack{}<\/code> the view is updated. This is especially useful if you want to add something more to the tab bar beyond text or an image. You could also add the selectedPage<\/code> to an @EnvironmentObject<\/code> to have control of those pages from anywhere in the app. It’s especially useful when creating logins or landing pages, where you need to swap the navigation stack.<\/p>\n
struct ContentView: View {\n    @State var selectedPage: SelectedPage = .first\n    \n    var body: some View {\n        VStack {\n            VStack {\n                switch selectedPage {\n                case .first:\n                    FirstView()\n                case .second:\n                    SecondView()\n                case .third:\n                    ThirdView()\n                }\n            }\n            \n            Spacer()\n            \n            HStack {\n                Button(action: { selectedPage = .first }, label: {\n                    Text(\"A\")\n                })\n                \n                Spacer()\n                \n                Button(action: { selectedPage = .second }, label: {\n                    Text(\"B\")\n                })\n                \n                Spacer()\n                \n                Button(action: { selectedPage = .third }, label: {\n                    Text(\"C\")\n                })\n            }.padding(.horizontal, 30)\n        }\n    }\n}\n\nenum SelectedPage {\n    case first, second, third\n}\n<\/code><\/pre>\n<\/p><\/div>\n
