I made a (very simple) custom tab bar in SwiftUI. It's simply an HStack containing two buttons. These buttons control the selection of a paged TabView. This works well, but in VoiceOver they don't behave like the bottom tab bar or e.g. a segmented picker. Specifically, VoiceOver does not say something like "tab one of two" when the first button is focused.
According to my research, in UIKit this can be accomplished by giving the container view the accessibility trait tabBar, hiding it as an accessibility element and give it the accessibility container type semanticGroup.
In SwiftUI, there is also the trait isTabBar, but that does not seem to have any impact for VoiceOver. I don't see an equivalent of semanticGroup in SwiftUI. I tried accessibilityElement(children: .contain) but that also does not seem to have any impact.
So, is there any way in SwiftUI to make a button behave like a tab-button in VoiceOver? And how is SwiftUI's isTabBar accessibility trait supposed to be used?
