iOS Functions in Swift Functions in Swift Recap: Functions

I need help on the return part of this question

I am not sure of what the question is asking me to do on the return part. But anyways here is the task I am stuck on. Declare a function named temperatureInFahrenheit. The function should take a single input named temperature of type Double and has a return type of Double.

For now, to make the function pass, simply return the value of the temperature parameter from the function. In the next task, we'll add more code to the body.

functions.swift
func temperatureInFahrenheit(temperature: Double) {
    return temperature: Double
}

You need to learn how to return values.

This should work:

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