Getter and Setter - Celsius <-> Fahrenheit

Hello !

why is this wrong ?

Thank you for your help !

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

In the setter method, you're setting a New Value to it.

So replace your fahrenheit with newValue and that's the only issue you have to fix in your code.
