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

It looks like you are missing a closing brace on your definition of fahrenheit!

Okay thanks. Now it says:

Bummer! The setter method for fahrenheit did not assign the right value to the celsius property. (Note: Celsius = (Fahrenheit-32)/1.8)

Ah yes! I missed that. A setter needs to be declared with a parameter. You then use that parameter in calculating the new value of celsius.

Hello Konstantin Mishukov, try this :)

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