The optional, user-visible subtitle for the Home screen dynamic quick action.
- iOS 9.0+
- Mac Catalyst 13.0+
If you specify a subtitle for a 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 dynamic quick action, employ the
NSLocalized Foundation function, described in Foundation Functions, along with a
Localized file in your Xcode project.
