iOS Object-Oriented Swift Properties Getter and Setter Methods

What am I doing wrong?

I'm sure I understand the getter and setter methods, but my code isn't working for this. Can anyone please help me?

Temperature.swift 
class Temperature {
    var fahrenheit: Float
    var celsius: Float {
        get {
            return (fahrenheit - 32) / 1.8
        }
        set {
            self.celsius = newValue
            fahrenheit = newValue
        }
    }
}

Almost. Try this:

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

The formula calls for (fahrenheit - 32) /1.8, but you can't use the property name, you need to use newValue.
