Hello there,

Does the UNNavigationController have to be the rootViewController to get the automatic conversion to an NSToolBar? For example, I have a UITabBarController which contain several views, each with their own UINavigationController but they are not converting to NSToolBars. Is this a beta 2 limitation?

Also, the sample code linked for session wwdc2022-10076 won’t compile for macOS vis Catalyst. https://developer.apple.com/documentation/uikit/app_and_environment/supporting_desktop-class_features_in_your_ipad_app

Thanks,

Matt

For anyone else stuck with this issue, it can be solved with UINavigationBarDelegate like so:

@available(macCatalyst 16.0, *)
    func navigationBarNSToolbarSection(_ navigationBar: UINavigationBar) -> UINavigationBar.NSToolbarSection {
        return .content
    }
