Help! Getter and Setter methods not working.

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

Aside from what Dan Johnson has pointed out about the getter method; there's also an issue in your setter method, you're supposed to use the predefined keyword newValue instead of fahrenheit.

celsius = (newValue - 32.0) / 1.8

cheers.

Remember that computed properties aren't actually stored, so you'll need to work with the celsius property to compute the values in the getter:

return (celsius * 1.8) + 32.0
