Tupes challenge 1 (Turning the greeting func into tuples)

Hi,

Im just curious if anyone can see whats causing error's in this code. Its pretty simple stuff just putting language and greeting into a tuple and then returning it inside the func....

Im getting error's on here but bizarrely enough Im not getting errors on the same code in the playground it seems to work fine

tuples.swift 
func greeting(person: String) -> (String, String) {


    let language = "English"
    let greeting = "Hello \(person)"

    var test = ("\(language)" , "\(greeting)")

    return test
}

Hi Matt,

The expected answer for this exercise is to name the return values in the method signature :

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

    return (greeting, language)
}
