Hey folks. Sometimes your online editor is having troubles with some code like this here. i have it running in xcode.

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

this is considered as not working by your editor.

Even if that code is runing, this is the correct way of doing it since later on you can access the greeting values

Simply use the function and you will see, I was thinking the same as you at first...

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

    return (greeting, language)
}

let salute = greeting("Tom")

salute.language
salute.gretting
