**[SOLVED]** why does this code work in xcode but not within the code challenge?

func temperatureInFahrenheit(temperature: Double) -> Double { return ((temperature * 9) / 5) + 32 return fahrenheit } let fahrenheitTemp = temperatureInFahrenheit(24.0)

functions.swift 
// Enter your code below
func temperatureInFahrenheit(temperature: Double) -> Double {
   return ((temperature * 9) / 5) + 32
    return fahrenheit
}
let fahrenheitTemp = temperatureInFahrenheit(24.0)

I figured it out! In case anyone comes on to this discussion: delete the return statement and it works a treat.

You're right. You can't have multiple return statements. You only need to be returning the evaluated temperature for Fahrenheit.
