temperatureInFahrenheit function problem my solution not working in your code editor

Here is my solution that compiles perfectly in xCode;

func temperatureInFahrenheit(temperature: Double) -> Double {

let fahrenheitTemp = temperature * 9 / 5 + 32

return fahrenheitTemp

}

temperatureInFahrenheit(24.0)

functions.swift
// Enter your code below

func temperatureInFahrenheit(temperature: Double) -> Double {

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

  }

  temperatureInFahrenheit(24.0)

Hey Tom,

For what the challenge is asking for, you got your code just a bit jumbled up. The constant declaration needs to be outside of the function, and it's to hold the actual function call. Inside the function, you are just to return the value of the math conversion. So, all the code is actually there, it just a little mixed up.

Here is the completed code for the challenge. Have a look, and I hope it makes sense. :)

func temperatureInFahrenheit(temperature: Double) -> Double {
  return temperature * 9 / 5 + 32
}

let fahrenheitTemp = temperatureInFahrenheit(24.0)
