Hi Ihosvany,

The challenge is simply asking for you to remove the println function and replace with with a return statement then assign the return type as a String, all of this was covered off in the previous video so I recommend you watch over it again just in case you missed anything the first time round.

func greeting(person: String) -> String {
    return "Hello \(person)"
}

Remember, to make a function return a specific value you use the arrow following argument assignments. Next, get rid of println(). The challenge wants what println() was returning to be returned by the function as a obtainabe value.

func greeting(person: String) -> String {
    return "Hello \(person)";
}

So now if I wanted, I can create a variable to hold the value returned by my greeting function:

var myFriendliness = greeting("Ihosvany Diaz");
myFriendliness //will return "Hello Ihosvany Diaz"
