900 PointsFunctions in Swift: why does my code compile in a playground but not in Treehouse?
My code works perfectly in a playground but says "Bummer! Your could.... check compiler"... however there is nothing in the compiler check. Is there something wrong with my thinking here?
// Enter your code below
func temperatureInFahrenheit(temperature: Double) -> Double {
let fahrenheitTemp = temperature * 9 / 5 + 32
return fahrenheitTemp
}
temperatureInFahrenheit(24.0)

25,909 PointsHi Barbare, I copy & pasted your code into the challenge and it worked for me. Maybe you just have to reload the site?
