How to do it...

Now, let's imagine that we are working on a game, and you have different types of monsters, and based on the type of monster, you will define power or the difficulty of the game. In that case, you have to use enum to create a monster type with different cases, as follows:

1. Type the following code to create enum with name Monster:

      enum Monster{ 
        case Lion 
        case Tiger 
        case Bear 
        case Crocs 
      } 
 
      enum Monster2{ 
        case Lion, Tiger, Bear, Crocs 
      } 

1. Use the '.' operator to create enums variables from the previously created enum:

      var monster1 = Monster.Lion 
      let monster2 = Monster.Tiger 
      monster1 = .Bear 

1. Use the switch statement to check the value of enum to perform a specific action:

      func monsterPowerFromType(monster:Monster) ->Int { 
    
        var power = 0 
    
        switch monster1 { 
          case .Lion: 
            power = 100 
          case .Tiger: 
            power = 80 
          case .Bear: 
            power  = 90 
          case .Crocs: 
            power = 70 
        } 
        return power 
      } 
 
      let power = monsterPowerFromType(monster1) // 90 
 
      func canMonsterSwim(monster:Monster) ->Bool{ 
    
        switch monster { 
          case .Crocs: 
            return true 
          default: 
            return false 
        } 
      } 
 
      let canSwim = canMonsterSwim(monster1) // false
