Help with tuple IOS activity.

I have just completed the Tuple IOS activity and am curious to why my code works on the treehouse environment but not the Xcode IDE.

My code is: func greeting(person: String) -> (greeting: String, language: String) { let language = "English" let greeting = "Hello (person)"

return (greeting, language)

}

var result = greeting("Tom") println(result.language)

On xcode I get the following error: Invalid redecoration of 'greeting'

What does this mean and is it a simple fix?

I tried it here on my Xcode and actually, it worked!

Here's the code: 

func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)
}

let result = greeting("Tom")

print(result.language)

I don't know which version of Xcode you're using, mine is the 7.0 Beta 3

If you're using an precious (And not beta) version - maybe is because you are using greeting for the name of the function and for the name of the tuple and constant

Try the name of the function (or tuple, or constant) for greetings but not all in the same time.

Hope it helped. ;)
