Confused

Hey guys I am confused and don't know what I am doing wrong. Any ideas? Thanks!

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 there,

You need to make use of newValue in there:

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

I hope that helps.

Steve.
