I am developing a tvOS application and I wanted to use a view like split-screen of course I need focus management in it. I've seen a video from WWDC and my research that this can be done with the prefersDefaultFocus(_:in:)modifier. I even made a little demo. While it works fine if TabView is not used on the screen, prefersDefaultFocus(_:in:) does not work when TabView is added.
Have any of you encountered this situation? How can it be overcome?
Here is my code sample, you can test both cases;
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
//ContentView()
ContentWithTabView()
}
}
}
struct ContentView: View {
@Environment(\.resetFocus) var resetFocus
@Namespace private var namespace
var body: some View {
HStack(spacing: 100) {
Group {
VStack {
Button ("1") {}
.prefersDefaultFocus(in: namespace)
Button ("2") {}
Button ("3") {}
}}
Group{
VStack {
Button ("1") {}
Button ("2") {}
Button ("3") {}
Button ("Reset to default focus") {
resetFocus(in: namespace)
}
}
}
}
.focusScope(namespace)
}
}
struct ContentWithTabView: View {
var body: some View {
NavigationView {
TabView {
ContentView()
.tabItem {
Image(systemName: "house.fill")
Text("Home")
}
ContentView()
.tabItem {
Image(systemName: "house.fill")
Text("Home")
}
}
}
}
}

Hi there,
If I open the preview with an iOS device while developing a screen, I can control it with the mouse and I can do actions such as scrolling and clicking. But if I preview a tvOS device, I can't control it with keyboard, or mouse. Can't we test the tvos devices in preview and try the focus actions?
Thanks,
