The system told me that i have the wrong value in my variable

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

    var welcomeMessage = ("Your language is \(language)", "\(greeting)")

    return welcomeMessage
}

This is what you are looking for :

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

    return (greeting,language)  // this is the return tuple 
}

var result = greeting("Tom")

println(result.language)
