# OOP Swift getter/setter

hi!

having trouble here with the get and set methods

question:

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))

error: Bummer! The setter method for `fahrenheit` did not assign the right value to the `celsius` property. (Note: Celsius = (Fahrenheit-32)/1.8)

Am I missing something?

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 Jordi,

As Amit explained in the previous video, setters have a special variable scoped within them called `newValue`, For this challenge we need to use this in the place of `fahrenheit` so we can convert the given value.

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

Happy coding!
