Help

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

Maybe the exercise expects that you define two variables and return them as a tuple.

Hi, you are returning only one value not 2 as a tuple, you need to specify the tuple at your return statement:

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

    return (language, greeting)
}

var result = greeting("Tom")
