I don't understand what's wrong with my code

I don't know why the variable result cannot accept the tuple.

my code:

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

var result(greeting,language) = greeting(person:"Tom")

The problem is with the variable.

Yeah you have some little errors. You have to do interpolation to add the variable person to your string, like this...

greeting = "Hello \(person)"

also it asks for ...

a variable named result .... assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)

so basically...

var result = greeting("Tom")

It doesn't ask for something complex.
