Raw value for enum case must be a literal

Question

I have this enum:

enum GestureDirection:UInt {
    case Up =       1 << 0
    case Down =     1 << 1
    case Left =     1 << 2
    case Right          


        

Answer 1

Swift 2.2 Version : In my case I needed to Convert the String Enum Values to be used in Localisable Strings. So added this method inside my enum.

    enum DisplayCellTitle: String {
    case Clear 

    func labelTitle() -> String {
        switch self {
        case .Clear:
            return "LBL_CLEAR".localizedWithComment("Clear")
        }
    }
}

And then Use it like so :

        // Get the localised value of the Cell Label Title
    let lblTitle = DisplayCellTitle.labelTitle(cellTitle)()

where cellTitle passed in is just one of these CellTitle Enum Values
