I've got a UIKit app with a collapsible trailing-edge child view controller, implemented sort of like UISplitViewController but it's got a bunch of custom behavior - moving to the bottom edge in portrait orientation, etc. It exposes a couple of different app functions via a UITabBar on the bottom edge on iOS.
When I run the app on visionOS, that tab bar transforms to a leading-edge ornament. This would be great, but that means it tries to overlap the trailing-edge content of its parent view controller, which isn't ideal.
Is there a way to get the tab bar to lay out on the trailling edge of the child view controller? Or can I create a custom ornament that has the same auto-expand behavior as the tab bar, where it shows a vertical column of icons that expands to show titles when you're gazing at it?
It is not possible to change the edge on which the tab bar appears using a UITabBarController but you could create your own ornament using the UIHostingOrnament and hoverEffect APIs (see https://developer.apple.com/videos/play/wwdc2024/10152).
