How to get the name of enumeration value in Swift?

Question

If I have an enumeration with raw Integer values:

enum City: Int {
  case Melbourne = 1, Chelyabinsk, Bursa
}

let city = City.Melbourne
         


        

Answer 1

There is no introspection on enum cases at the moment. You will have to declare them each manually:

enum City: String, CustomStringConvertible {
    case Melbourne = "Melbourne"
    case Chelyabinsk = "Chelyabinsk"
    case Bursa = "Bursa"

    var description: String {
        get {
            return self.rawValue
        }
    }
}

If you need the raw type to be an Int, you will have to do a switch yourself:

enum City: Int, CustomStringConvertible {
  case Melbourne = 1, Chelyabinsk, Bursa

  var description: String {
    get {
      switch self {
        case .Melbourne:
          return "Melbourne"
        case .Chelyabinsk:
          return "Chelyabinsk"
        case .Bursa:
          return "Bursa"
      }
    }
  }
}
