I'm really stuck in Task 2 here, the fact that both the function and a constant are named "greeting" really confuse me.

What should I do here? It feels like this task asks for something not covered during the previous video.

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

    return (language, greeting) 
}

var result = greeting(greeting: "Kim")

The instructions say pass "Tom" to the greeting function in task 2, not "Kim." Also, "Tom" is passed in for the parameter, "person" (which isn't a named parameter so lose the "#" in front of it).

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

    return (greeting, language)
}

var result = greeting("Tom")
