Getter/Setter Methods

Struggling to get this working. I understand the premise of Getter and Setter methods, but I can't seem to get the syntax down properly. Can anyone help or advise? Thank you in advance!

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

Hello Tyler:

You are doing well, your code looks good so far, but in your setter, you don’t have to declare the keyword*newValue*. Instead you can just use it directly. 

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

Hope this helps. If you need a more detail explanation please let me know.

Good luck.
