问不直接从其他视图控制器推断枚举类型

EN

class MyRootViewController: UIViewController {
    enum Animation {
        case left
        case right
        case top
        case bottom
        case none
    }
  //some code
}

class OtherViewController: UIViewController {
  enum Configurations {
        case config
        case version
        case type
    }
  //some code
}



 class Utility {
   func addConfiguration(_ config: Configurations) {
    //some code
    }

   func showAnimation(_ animation: MyRootViewController.Animation) {
   //Some code
   }
  }
