Here is my code in the challenge of getter and setter session, I could not find my mistake, please give me some help.

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

Hi Ye,

The challenge wants you to add a getter and setter method to the fahrenheit property. For classes with unassigned values you need an initializer, but what you have here is a computed property which does not require you to have one. 

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