The code looks good and no errors but it won't accept it. First one i can't get past

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

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

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

Same Error, tried multiple things.

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

Hi Brian,

in your setter, you need to use 'newValue':

  set {
    celsius = (newValue-32.0)/1.8
  }
