What is the correct answer?

I don't understand how to do this question.

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

Hi Shayan,

This one causes quite a bit of confusion, yes!

You need to use the newValue concept in here:

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

Hope that helps!

Steve.
