Categories of apps for the system to cover with a shielding view.
Declaration
var applicationCategories: ShieldSettings.ActivityCategoryPolicy<Application>? { get set }Discussion
When the user launches an application in one of these categories, the system calls your extension that customizes the shield’s appearance. When the user taps on a button the shield displays, the system calls your extension that handles user actions. Your app is exempt from .all. If your app doesn’t provide a list of categories to shield, this value is nil. Your app can shield up to 50 category tokens and specify up to 50 application tokens exceptions at once.
