How to get the name of enumeration value in Swift?

Question

If I have an enumeration with raw Integer values:

  case Melbourne = 1, Chelyabinsk, Bursa
}

let city = City.Melbourne
         


        

Answer 1

For Swift:

extension UIDeviceBatteryState: CustomStringConvertible {

    public var description: String {
        switch self {
        case .unknown:
            return "unknown"
        case .unplugged:
            return "unplugged"
        case .charging:
            return "charging"
        case .full:
            return "full"
        }
    }

}

if your variable "batteryState" then call:

self.batteryState.description
