localizedAdditionalDescription
A more specific localized description of tracked progress for the receiver.
Declaration
var localizedAdditionalDescription: String! { get set }Discussion
If you don’t specify your own custom value for this property, Progress uses the value of the kind property to determine how to use the values of other properties, as well as values in the user info dictionary, to return an automatically computed string. If it fails to do that, it returns an empty string.
The localizedAdditionalDescription is more specific than localizedDescription about the work the receiver is tracking at any particular moment. Depending on the kind of progress, the completed and total unit counts, and other parameters, localized additional descriptions resemble the following:
