HI Alistair!

Challenge Task 2 of 3 asks you to "Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)"

(1) You wrote var result before (greeting: String, language: String)by mistake

(2) You forgot to assign the result of greeting("Tom") to the variable result

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

var result = greeting("Tom")
