Please help

I am at the second step of the last tuple exercise and i am asked to: "Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)

In Xcode, my "result" value is Hello Tom but in the exercise they give me the “You need assign the return value of the 'greeting' function to 'result’.”

Can someone please help me and tell me what I’m doing wrong?

Raymond:

Looking at your code there are a few things that you have to fix.

First part of the challenge says to return a tuple. 

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

    return (greeting, language) // We are returning the tuple
}

Second part, it says to create a variable. 

var result = greeting("Tom")

Third part

println(result.language)

Hopefully this helps.

Good luck

So this is the code that works for e in Xcode:

func greeting (person: String) -> (greeting: String,language: String){

    let greeting = "Hello \(person)"
    let language = "English"

    var found = (greeting, language)

    return found

}
var (result,_) = greeting("Tom")

result

I also got caught by this one, make sure that the order of the returned tuple is the same order as named parameters of the function.
