I do what is supposed (I am pretty sure, 90%) but still it won't accept it...

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 Anton,

You're right - you're 90% there!!

In the set part, you need to use newValue, not fahrenheit.

Something like this should be fine:

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

I hope that helps,

Steve.
