localizedSubtitle
The optional, user-visible subtitle for the Home Screen dynamic mutable quick action.
Declaration
var localizedSubtitle: String? { get set }Discussion
If you specify a subtitle for a mutable quick action, the system then displays the title on a single line (potentially with an ellipsis character), no matter how long the title is.
To internationalize the subtitle for a Home Screen mutable, dynamic quick action, employ the NSLocalizedString Foundation function, described in Foundation Functions, along with a Localized.strings file in your Xcode project.
