How to return a single value to a get statement

Compiler is giving me no detail on what's wrong with this code... just saying "BUMMER, Try Again"

It seems to not like the return clause of the get statement... and I assume it's the way I'm trying to get the existing value for fahrenheit.

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

Here, it should look like this: 

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