Hi csaba nemeth,

You're very close, you simply have your return type backwards as greeting needs to comes first.

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

var result = greeting("Tom")

What about the 3rd part. It is very confusing, by the way..

Task 3 is the simplest part of the challenge and was explained in the previous video, any time you have a named tuple you can access it's value just like you would access a property in a struct.

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

Actually the 3rd part is clear, but I don't really understand why confusing the students with this order thing :), everybody knows my code is works perfectly. Add names to return values makes the order pointless, actually thats why it exists.

I very grateful the help tough, cause I sucked about it for 2 hours.
