How do I use function to convert from Celsius to Fahrenheit?

How do I use function to convert Celsius to Fahrenheit? The temperature must be of type Double and the formula to convert Celsius to Fahrenheit is by multiplying the value of Celsius by 9, then dividing the result by 5 and then add 32.

functions.swift 
// Enter your code below
func temperatureInFahrenheit(temperature: Double) -> Double {
      let Celsius = 10.0
      let fahrenheit = (10.0 * 9.0) / 5.0 + 32.0
      return fahrenheit
}

The challenge didn't ask you to make a variable called Celcuis.

You should be multiplying the temperature argument by 9 and dividing 5 etc.

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

If you fix that issue you should be fine :)
