iOS Object-Oriented Swift Properties Getter and Setter Methods

Posted by Hammad Nasir

I'm stuck here, please tell how to figure this one out!

I'm unable to get what the line : "Then add a setter method. When the user assigns a value to the fahrenheit property, the setter method will calculate and assign a value to the celsius property. (Note: Celsius = (Fahrenheit-32)/1.8))" is saying!

I've attached my code below, kindly tell me where I'm wrong and/or lacking something.

Thanks in advance,

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

I Think you will need something like that :

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

Hope that helps.

Yeah, this helped. Although there is an error in your syntax too. You should have written: celsius = (newValue - 32) / 1.8

Thanks!
