Celcius to Fahrenheit conversion function

I'm having trouble logically thinking through a script for the function. Take Celsius, multiply it by 9, divide by 5, add 32 to get Fahrenheit and once a value for Fahrenheit is found, return it.

// Enter your code below
func temperatureInFahrenheit(temperature: Double, celcius: Double) -> Double {
let celcius = 50.5
let temperature = (( celcius * 9) / 5) + 32
return temperature

To begin with, the challenge specifically states that you are only taking one Double and returning one double. This is how I solved it.

func temperatureInFahrenheit(temperature: Double) -> Double {
  return temperature * 9 / 5  + 32

I took one temperature, and returned the result after the conversion.
