Your problem there is nothing to do with tuples, but with how to do string interpolation (where you're trying to insert the 'person' variable into your string).

You may want to either look up Swift string interpolation or go back and rewatch the relevant Swift Basics video lessons here - I'm sure you'll see your mistake soon then.

I've tried This :

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

I know about String Interpolation and i can't get it with this scenario i'm also looking at this site for help :

Hi - like I said, you are making a mistake with your string interpolation. Read the code in that article you posted carefully, and you will see quite early on there is an example of string interpolation you can copy.

Also I know it's quite confusing but remember to respond to answers here by pressing the 'Add Comment' button below an answer (like I am now) rather than adding a new answer everytime to discuss things, like you (and lots of other people all the time) just did :)
