I've watched the videos 10 times each and still can't figure out the answered to this tuples question. I need help.

Where can I get the answer to this question before I throw my laptop out the window. It is getting very frustrating.

It is the last challenge in the first Swift - functions lessons

I'm not sure which last challenge you are talking about. The first and third part of Swift Functions and Optionals have questions that have nothing to do with Tuples. But the second part does. So here are the answers to the last questions of each part's challenge:

The answer to the last challenge in Swift Functions and Optionals -> Functions is:

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

The answer to the last question of the challenge Swift Functions and Optionals -> Optionals 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)

and the last challenge in Swift Functions and Optionals -> Optionals is:

func isNotDivisible(#dividend: Int, #divisor: Int) -> Bool {
  if dividend % divisor != 0 {
    return true
  } else {
    return false
  }
}

Hi, here is my solution:

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

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

return (greeting, language)

}

hope it helps.
