You simply have your tuple backwards, greeting should come first then language.
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}

everything looks fine but just try changing the order of "language" and "greeting" in your tuple like this and it'll work:
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
var result = greeting("Tom")

Courses Plus Student 7,225 PointsIs there any reason why that matters? I thought the pointed of named variables is that they're accessible by name instead of location.
will still yield
'''swift result.greeting // "Hello Tom" result.language // "English" '''

50,595 PointsYou could access "language" and "greeting" via the index notation as follows:
...in this case the order of the variables in the return statement would matter but IMHO you're right that the challenge should accept your answer anyway :)

For this challenge the order does matter as it's explicitly stated in the task question, however for real life purposes if you have named tuples you don't need to worry about the order since you can access the values simply using their name. See the below link as a I wrote in a bit of detail the different ways you can use tuples.
