I don't understand how to place a return value, into a variable? In iOS

How to I add the return value to a variable

func greeting(person: String) -> (greeting: String, language: String) {

    return (greeting,language)
    var result = (greeting,language)

Hi Collin

So, to declare a variable you use the keyword var followed by blank space and the name of the variable, right?

var someVariable

To give this variable a value you simply add an equals sign and whatever value you like, yes?

var someVariable = "Some Value"

In your case you want to think of greeting("Tom") as if it is already a value that you can assign to the variable.

var result = greeting("Tom")

Now result holds the value returned from the greeting function - understand?

Best of luck with swift/iOS

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

    return (greeting, language)
    var result = greeting("Tom")
