What is the proper syntax for assigning a variable to a tuple returned from a function?

See code

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

    return (language, greeting) 
}

var result = greeting(person: "Tom")

'''html<p>your code is actually correct but since there was no "#" before the parameter "person" in the function, the computer does not recognize the parameter "person" you added in "var result = greeting(person: "Tom". Just write your code like that by removing the the parameter "person" in the variable result and it shall work.

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

return (language, greeting)

} var result = greeting("Tom") </p>'''

Thanks for the input, that makes complete sense, the problem is asking me to assign the tuple returned from the greeting function to the variable result. However even after removing the parameter "person" I had now success. Any other thoughts as to what is wrong with this? Even in X Code it shows that the tuple is correctly assigned to the result variable.
