What is wrong with my Code?

I have tried using return(greeting,language) and I have tried using the strings instead of the constants because I told the function to return two strings. I even created a variable that consisted of the conactation of greeting and language and then tried to return that. I dont understand what I am doing wrong.

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

    return (greeting,Language)
}

I think you made a typo? You capitalized language or vise versa? 

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

The typo wasn't the major issue. The major issue was that you're declaring the return value to be (String,String) when it should have the constant name before each one.

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

    return (language, greeting)
}

var output = greeting("Dave")
println(output) // just to see output for testing purposes
