If you set the frame width on the tabview, the page will not change on rotation. I use the maximum of the screen width and height as the tabview frame width, and that seems to work well. struct ContentView: View {     @State var currentPage: Int = 1     var body: some View {             ZStack {                 TabView(selection: $currentPage) {                     Text("1").tag(0)                     Text("2").tag(1)                     Text("3").tag(2)                 } .frame(width: max(UIScreen.main.bounds.width, UIScreen.main.bounds.height))      .indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .never)) .tabViewStyle(PageTabViewStyle())         }     } }
