I cannot see where the calculation is going wrong, I get the error saying that celsius is not calculated correctly

Is the calculation wrong or have I written the statement wrong? thanks

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
        }
    }    
}

You need to use newValue instead of fahrenheit as you have just changed this with the get

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

Thank you, I had tried newValue in place of celsius instead.
