Declaration

var identifier: String? { get }

Discussion

You assign identifiers to your segues in Interface Builder. An identifier is a string that your application uses to distinguish one segue from another. For example, if you have a source view controller that can segue to two or more different destination view controllers, you’d assign different identifiers to each segue so that the source view controller’s prepare(for:sender:) method could tell them apart and prepare each segue appropriately.
