Hi there Benjamin! Well you've got the first part set up correctly. But you never tell it what type to return. And then we also have these instructions:

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.

So your code at the end of the first step should look like this:

// Enter your code below
func temperatureInFahrenheit(temperature: Double) -> Double {
  return temperature

We define the function that takes a type Double which will be named temperature inside the function. That part you did just fine. Then we return a double. And in this case, we're going to return temperature. Hope this helps! :sparkles:
