You have created the function to take in two arguments, it should only take in one. Then return the value passed in:

func temperatureInFahrenheit(temperature: Double, return: Double) {
// =================================================^ Remove this.
    return // Add a call to the `temperature` variable here.
}

It should look like this:

func temperatureInFahrenheit(temperature: Double) -> Double {
    return temperature
}

Or

func temperatureInFahrenheit(temperature: Double) -> Double {
    return temperature
}

Anytime, I was not 100% certain but I thought we needed to declare the return type -> Double so I posted. If it helps I'm happy :)
