Tuples, tuples, tuples...Can someone lead me in the right direction on how to, "Create a variable named result and assign it the tuple returned from function greeting. (Note: Pass the string "Tom" to the greeting function.)? More specifically, I keep receiving a "Bummer" with assigning the return value of the greeting function to result.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
var result(greeting: "Tom")
}

Please note that in general when you write return ..... the function is basically done: if you write code (inside the function, but after the return statement, it won't be executed).
In your case, you want to declare a variable outside, the function, so code needs to go beneath it.
Your piece of code "var result" looks correct, but then we need to assign it (using the "=" sign) to the function call, passing the "Tom" string as the parameter inside the parenthesis.
Let me know if this makes it clear.

3,457 Pointsyou are on the right track.. you just need to call that result variable outside of the function
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language) }
var result(greeting: "Tom")
hope that helps

1,853 PointsThanks again Meek D and Vittorio Somaschini. I was missing the # symbol before "person" in the function parameter. I also found out that I needed to write my answer as " var result = greeting(person: "Tom") "

1,853 PointsThanks for your quick response and great explanation Vittorio Somaschini ! I really appreciate you reaching out trying to help me on such a short notice. I'm still missing something but will have to figure it out tomorrow. I'm not a programmer by nature and this one thing seems to be very challenging.
