Stuck at this challenge cant figure out how to get the setter method to work

Help is appreciated

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 Robin

In your set block you need to use newValue instead of fahrenheit. There should also be a set of parentheses around newValue - 32

Your code should end up looking 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
    }
  }
}
