I am being told that my function is not correct, but it works in xcode?

func temperatureInFahrenheit(temperature: Double)->(Double){ return temperature }

functions.swift 
// Enter your code below

func temperatureInFahrenheit(temperature: Double)->(Double){
     return temperature
}

The testing scripts that workspaces run are confused by your brackets around your return value.

Try to avoid using unnecessary markup in your code. While often syntatically valid to the compiler (mostly for Objective-C support) it does confuse the workspaces testing scripts. :)

Your code would look like this.

func temperatureInFahrenheit(temperature: Double) -> Double {
     return temperature
}

Keep up the great work! :)

I couldn't see why it wasn't working, especially as I work as a swift dev this is something I do quite a lot so I was sure I was right
