        return (celsius * 1.8) + 32.0

Hey Adam Siwiec,

Inside of your setter, you want to use the local constant newValue instead of fahrenheit. This constant is provided by Swift and stores the new value you are setting. 

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

Good Luck
