iOS Swift Functions and Optionals Parameters and Tuples Tuples

Trouble returning a tuple

I can't figure out whats wrong. The compiler says it can't convert type string to type (string, string). Please let me know what I'm doing wrong.

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

Hi Conor Quinn !

Challenge Task 1 of 3 asks you: "Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task."

You forgot to name each item in the tuple like this: -> (greeting: String, language: String)

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

    return (greeting, language)
}

your function works on my playground... At the top did you import UIKit?

My answer matches Holger's, at first glance.

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

    return (greeting, language)
}
