Why is fahrenheitTemp not returning my results?

func temperatureInFahrenheit(temperature: Double) -> Double {

    let fahrenheitTemp = (temperature * 9)/5 + 32
    return fahrenheitTemp

}

   let temperature = 24.0

Hi Tanner,

It looks like you are trying to assign a value to the parameter instead of calling the function with a parameter passed in, as the instructions are stating. Remember when calling a function it is the function name with the parameter(s) passed into the parenthesis => functionName(parameter)

Have a look over the part of the code where you should be calling the function. The rest looks good! :thumbsup:

Keep Coding! :) :dizzy:

Your last line: let temperature = 24.0 is trying to assign a hard-coded value to the variable, but the instructions specifically state to store the "return of the function call to the variable".
So, you need to call the function with the value of 24.0 passed in, and then store that into the variable named fahrenheitTemp not temperature:

let fahrenheitTemp = temperatureInFahrenheit(temperature: 24.0)
