Tuples issue!

Hey all,

I'm stuck on the Tuples challenge in the Swift iOS Dev course. I've been trying to figure it out for hours, please someone help! Thanks.

This is my first time posting and I think i've attached the code, please let me know if there are any issues.

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

    return greeting
}

Just invade anybody has issues with this:

You need to return (language, greeting)

And after the -> you must (language: String, greeting: String)

Easy as pie when you know how but I recommend watching the video again :)

Just reposting the solution above as an answer so the question shows up as answered:

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

    return (language, greeting)
}
