Help Please?

Why is my code wrong?

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 
              fahrenheit = (celsius * 1.8) + 32.0
        }
    }    
}

Check out this forum link if you have any questions,

https://teamtreehouse.com/forum/cannot-complete-objectoriented-swift-code-challenge

"This task has caught a few people off guard mainly because of the random fahrenheit occurrence which doesn't actually belong there, if you remember back in the previous video Amit shows us a variable that's scoped to the set method on the computed variable called newValue.

Instead of fahrenheit we want to use newValue instead."

Find the answer below;

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

Anthony, I tried the code and it didn't pass until I put a space between the 'get' and curly brace, so I changed it.
