Is there a reason why he did use struct instead of enum?

    struct Key {
        static let firstName = "firstName"
        static let lastName = "lastName"
        static let phone = "phoneNumber"
        static let email = "email"
        static let street = "streetAddress"
        static let city = "city"
        static let state = "state"
        static let zip = "zip"
        static let image = "avatarName"
    }

Couldn't we just use enum?
