What is wrong with this code in the Getter and Setter?

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

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); newValue
        }
    }    
}

Your code 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
          }
    }    
}
