How to use swift enums?

Example:

  enum Direction {
      case north, south, east, west
  }
  var dir = Direction.north
  

Enums are used to define a type with a limited set of possible values. Above, we defined a 'Direction' enum.

Solution:

  switch dir {
  case .north:
      print("Going up!")
  case .south:
      print("Going down!")
  default:
      print("Moving around")
  }
  

This demonstrates how to use a switch case with the enum to handle different directions.
