How do i return a tuple of two strings.

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

greeting = ("\(greeting), \(language)")
return greeting

}

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

    greeting = "\(greeting), \(language)"
    return greeting
}

You've correctly modified your method signature, which is the first step:

func greeting(person: String) -> (greeting: String,language: String) {

But in the body of your method, you are still only returning greeting, which contains a single value. You need to return a tuple, so pass in both of your variables into your return statement as a tuple.

return (greeting, language)
