Let's add some code to the body of the function. Get rid of the existing return statement that's in there and in this task we're going to write out code to take a Celcius temperature value passed in and convert it to Fahrenheit.
To convert from Celcius to Fahrenheit - multiply the value by 9, divide the resulting value by 5 and then add 32.
Once you have the Fahrenheit value, return it from the function.
// Enter your code below
func temperatureInFahrenheit( temperature: Double ) -> Double {
temperature = (((temperature*9)/5)+32)
return temperature
}

35,864 PointsAlmost! You don't need to re-assign temperature. Simply return the result directly:
// Enter your code below
func temperatureInFahrenheit(temperature: Double) -> Double {
return (temperature * 9 / 5) + 32
}
Technically, your solution would work just as well, although a bit longer than it has to be. But I've noticed Treehouse's solution algorithm isn't actually based on the Swfit compiler or unit tests, such that it rejects solutions which would actually work. Rather, it seems like it's just pattern matching for the expected answer.
