Tuples Troubles in Swift

Hi, I am confused with the use of Tuples. I am having trouble with this code challenge.

Directions For Code Challenge: 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.

My Code

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

    return gl
}

Hi Robert,

Your code is almost correct, you're just missing the names from your return types which is the same <name:T> expression we give to parameters.

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

    return (greeting, language)
}
