I don't know what I'm doing wrong, nor how to move on... this is what I have:
func greeting(person: String) -> (greeting: String, language: String) { let language = "English" let greeting = "Hello (person)"
return greeting
}
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return greeting
}

You've got the method signature amended correctly - you now need to amend the method body to return the two variables:
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language) // <- change to this!
}
Hope that helps !
Steve.

7,308 PointsAwesome, it worked! Seemed that I was close. Unfortunately teamtreehouse doesn't hint you on what's missing or might be wrong like Khanacademy does.. Thank you for your answer Steve!

57,712 PointsHi,
If you clicked the preview button when you get an error, it shows you the compiler messages. In this case the error would have shown:
swift_lint.swift:11:12: error: 'String' is not convertible to '(greeting: String, language: String)'
return greeting
^
That can help pin down the precise issue with the code.
Steve.

7,308 PointsI did, but such error messages are Chinese for me at this moment :-)

57,712 PointsAh, yes. At first, they make little sense! :-)
