[RESOLVED] It says I did not assign the right value to the celsius property??

Pleas help me guys, I tried everything, but can't find out why!

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 Gopal,

This one's a little tricky. The related course video mentions a special variable named newValue, which is within the scope of Swift set methods. We're going to need to use this variable to represent and convert fahrenheit.

            celsius = (newValue - 32)/1.8

Hope this helps!

Thank you too CJ, i was kind of stuck too. Related to how newValue works is very simple, it refer to the new value that is asigned or input by the user
