In challenge task 1 of 3 in Stage 2 of Parameters and Tuples (Swift Functions and Optional Course) it states to "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."
I tried this, which seemed to work in playgrounds as I thought, but kept getting the Bummer! error. Any ideas?:
func greeting(person: String) -> (String, String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}

If you remember back to when Amit was explaining about tuples and naming the values he showed a couple of examples of named return values which are tuples, so what the challenge is asking for is what Amit taught in the previous video.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
One thing Amit doesn't actually teach us it that because these return values are named we can assign them out of order.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (language: language, greeting: greeting)
}
Not the best names but it's a nice way to see the power of tuples.
