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

fahrenheit = (newValue) won't work because you're kinda recursively using the setter of the fahrenheit property.
...but you where near the solution:
class Temperature {
var celsius: Float = 0.0
var fahrenheit: Float {
get{
return (celsius * 1.8) + 32.0
}
set {
celsius = (newValue - 32) / 1.8
}
}
}
