Can someone show me what I'm doing wrong here? Thanks

.

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

    return (greeting, language)
}

var result = greeting("Tom") { 
println language
}

It is quite straight forward. Your function's name (Greeting) is the same as the variable in your function.

Actually, I think you're forgetting to put the () on the println function and to call the value of the tuple I used the name of the Var that are receiving the function . the name of the tuple

Obs: there's no need to use "{}" after you create the var.

Something like: 

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

    return (greeting, language)
}

var result = greeting("Tom") 
println (result.language)
