Parameters and Tuples

I don't understand exactly what should do. I suppose, I did everything but it doesn't work. Please tell me where are my mistakes?

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

    return greeting

}

Hi Artem,

You have the general gist of what's been asked but have your code in the wrong spot and are missing the correct return type, so as you can see below the following has changed.

  • The tuple is where the return type String was
  • The return value within the greeting function now returns a tuple containing the greeting and language constants.
func greeting(person: String) -> (greeting: String, language: String) {
  let language = "English"
  let greeting = "Hello \(person)"

  return (greeting, language)
}

Happy coding!

Thank you. I was stuck here too. Practice practice practice...
