can anyone find the easter egg?

hi guys! this code is working on Xcode and I really can't find what could be the reason for it not to run.

it says check the preview section for compiler errors, but it is not showing any compiler errors either.

functions.swift 
// Enter your code below
func temperatureInFahrenheit(temperature:Double) -> Double{
let fahrenheitTemp = (temperature * 9) / 5 + 32 
return fahrenheitTemp
}
temperatureInFahrenheit(24)

You are doing it right, but they want you to declare a global constant using that function. So the let will be outside.

Your code would look like this.

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

let fahrenheitTemp = temperatureInFahrenheit(24)
