I have a tabView with several views, and I would like to know how to undefine a default view when loading it. By default, Xcode assigns the first view but I want the second view to be loaded when the application is launched.
var body: some Scene {
WindowGroup {
TabView {
alertView()
todayView()
forecastView()
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
.onAppear
{
UIPageControl.appearance().currentPageIndicatorTintColor = .black
UIPageControl.appearance().pageIndicatorTintColor = UIColor.black.withAlphaComponent(0.2)
}
}
}
Let's move everything in explicit scene root view
var body: some Scene {
WindowGroup {
ContentView()
}
}
And now we can use selection
for this, like
struct ContentView: View {
@State private var selection = 2 // << here !!
var body: some View {
TabView(selection: $selection) { // << here !!
alertView().tag(1)
todayView().tag(2) // << here !!
forecastView().tag(3)
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
.onAppear
{
UIPageControl.appearance().currentPageIndicatorTintColor = .black
UIPageControl.appearance().pageIndicatorTintColor = UIColor.black.withAlphaComponent(0.2)
}
}
}
