iOS Object-Oriented Swift Properties Getter and Setter Methods

It's insane that I've been bogged down on this challenge for nearly an hour, correct?

Simply cannot get beyond this compiler error:

The setter method for fahrenheit did not assign the right value to the celsius property. (Note: Celsius = (Fahrenheit-32)/1.8)

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

Hi Owen, You need to use the 'newValue' variable:

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