How to create scrolling pages of content using tabViewStyle()

SwiftUI’s TabView doubles up as the equivalent to a UIPageViewController, letting us swipe through multiple screens of content, with paging dots at the bottom to show users where they are.

To activate the page view style, attach the .tabViewStyle() modifier to your TabView, passing in PageTabViewStyle().

For example, you could add this to your @main Swift file:

struct SwiftUITestApp: App {
    var body: some Scene {
        WindowGroup {
            TabView {

Warning: The paging dots are white and translucent white, so if your view background is also white you won’t see them.

To solve this, either ask SwiftUI to place a background behind by placing extra modifier after tabViewStyle():

.indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always))

Or just give your views a background color, like this:

struct ContentView: View {
    var body: some View {
        Text("Hello, World")
            .frame(maxWidth: .infinity, maxHeight: .infinity)

You can control the way paging dots are shown by adding an extra parameter to the PageTabViewStyle initializer. For example, if you never wanted the paging dots to be shown, you would use this:

.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
