object-Oriented swift

according to this code, it says that the answer of the code it es not correct. I have tried several ways and i can't find how to solve it.

What am i missing?

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

I think it may be easier for us to help you if you also let us know what the question was asking you to do!

The task is: We need to add getter and setter methods to the fahrenheit property of the Temperature class. Add a getter method to the access the value of the fahrenheit property. Then add a setter method. When the user assigns a value to the fahrenheit property, the setter method will calculate and assign a value to the celsius property. (Note: Celsius = (Fahrenheit-32)/1.8))

I think you need to use "newValue" instead of fahrenheit.

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

Mmmm sorry but that does not seems to be the problem. And you are using float, the problem sets yo up with Double. But still with Floats it does not work.

Any other ideas?

this is what i did:

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