I do not see what is wrong in my second answer. It just say " Bummer! Your `result` variable has the wrong value in it.

I do not see what is wrong in my second answer. It just say " Bummer! Your result variable has the wrong value in it. Check the task instructions again."

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

var result = greeting("Tom")

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

var result = greeting("Tom")

Why did you change the return value to include the values that were previously held in variables? Those need to remain in their variables and you need to return the values using the variables.

Thanks Patrick for your quick answer.

But, the issue is with the order of variables. I made a minor change and it works.. which is misleading as no where instruction is given that I need to follow order for tuple.

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

I realized it when I wrote below and still it bumped.

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

let result = greeting("Tom")
