enum Character {
  enum Weapon {
    case Bow
    case Sword
    case Lance
    case Dagger
  }
  enum Helmet {
    case Wooden
    case Iron
    case Diamond
  }
  case Thief
  case Warrior
  case Knight
}
//Access like this:
let character = Character.Thief
let weapon = Character.Weapon.Bow
let helmet = Character.Helmet.Iron

When accessing nested enumeration members, it is not necessary to enter such a long level every time to access them. You can use convenient methods to access them directly.
