What am I doing wrong?

What am I doing wrong other than naming a variable x? I get no output and have no idea what is wrong.

Temperature.swift 
class Temperature {
    var celsius: Float 
    var x: Float {
      return (celsius * 1.8) + 32
    }
    init(celsius: Float) {
    self.celsius = celsius
    }
}

let fahrenheit = Temperature(celsius: 0.0)
fahrenheit.x

Hi Jason,

I just copied your code into a playground and am showing 32 as the return from the Temperature class. There should not be any output in your console output in your assistant editor, as you are calling the println() or other similar function.

'''html<p> Hey jason, in the challenge they want you to name the computed property as "fahrenheit" and not "x". Despite the fact that your code is correct, the computer will let you go on if you only follow the instructions. This is how your code should look:class Temperature { var celsius: Float var x: Float { return (celsius * 1.8) + 32 } }</p>'''
