UIKit Identifiers

Enums can be used to map reuse identifiers or storyboard identifiers from stringly typed information to something the type checker can understand. Imagine a UITableView with different prototype cells:

enum CellType: String {

     case buttonValueCell = \"ButtonValueCell\"

     case unitEditCell = \"UnitEditCell\"

     case labelCell = \"LabelCell\"

     case resultLabelCell = \"ResultLabelCell\"

}
