iOS Object-Oriented Swift Properties Getter and Setter Methods

Getter and Setter task problem : /. I seem to have the wrong calculation in the following code:

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

the task is:

We need to add getter and setter methods to the fahrenheit property of the Temperature class. Add a getter method to the access the value of the fahrenheit property. 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))

Would really appreciate the help!

Thanks : )

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

Try this for the setter: set { celsius = (newValue-32)/1.8 }

This setter worked for me: set { celsius = (newValue-32)/1.8 }

Hey

It worked!

Thanks!
