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)). Who can help me?

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
}
}
```

A get method gets the value of the variable (fahrenheit). A setter will set that value you passed it. It's asking for you to make a setter and a getter. But in the setter to set both the fahrenhrit and celsius variable.

Here is a rough draft of what they want.

``` var fahrenheit: Float {
get {
return fahrenheit
}
set {
fahrenheit = newValue
celsius = (fahrenheit - 32) / 1.8
}
```

Can you make it in Swift?

Sorry I went to Java in my head it's my main language. I have updated the answer with a rough layout.

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

}
}
```

Still wont work???

it still didn't work

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