Default value for Enum in Swift

Question

I have an enum :

public enum PersonType:String {

 case Cool                       = \"cool\"
 case Nice                       = \"rude\"
 case

To answer your question:

public enum PersonType:String {

    case Cool                       = "cool"
    case Nice                       = "rude"
    case SoLazy                     = "so-lazy"
    static var `default`: PersonType { return .SoLazy }

    public init(rawValue: RawValue) {
        switch rawValue {
        case PersonType.Cool.rawValue: self = .Cool
        case PersonType.Nice.rawValue: self = .Nice
        case PersonType.SoLazy.rawValue: self = .SoLazy
        default: self = .default
        }
    }

    public var description: String {
        switch self {
        case .Cool:
            return "Cool person"
        case .Nice:
            return "Nice person"
        case .SoLazy:
            return "its so lazy person"
        }
    }

    public var typeImage: String {
        switch self {
        case .Cool:
            return "cool.png"
        case .Nice:
            return "img_nice.png"
        case .SoLazy:
            return "lazy.png"
        }
    }

}

Now since having no failable initializer with default value replace your:

if let personType = PersonType(rawValue:personTypeKey ?? "") {
   self.personType = personType
}

With:

personType = PersonType(rawValue: personTypeKey)
