Temperature.swift

How do I get this to work??

Temperature.swift 
class Temperature {
    var celsius: Float = 0.0
    var fahrenheit: Float {
        get {
        return celsius * 1.8 + 32.0
        }
        set {
        fahrenheit = newValue
        celsius = newValue - 32 / 1.8
        }
    }    
}

Bob, it seems that your code is correct but you added one thing that didn't need added. In the setter space of the fahrenheit variable, you don't need to set the fahrenheit to the new value. Your correct code should look like this: 

class Temperature {
  var celsius: Float = 0.0
  var fahrenheit: Float {
    get {
      return (celsius * 1.8) + 32.0
    }
    set {
      celsius = (newValue - 32) / 1.8
    }
  }
}
