Hi Tony, maybe the second part of the challenge is a bit confusing to understand. In the challenge the second part was described as follows:

Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant. As an example, the final value of greeting could be "Hi there, Linda.".

An interpolated string is a string in which you combine usual string characters and a stored value, such as the constant name for example. The stored value (name) is written inside of a pair of parentheses behind a backslash like in my example here below.

// Enter your code below

let name = "Jens"
let greeting = "Hi there, \(name)."

I hope this explanation helped! / Jens

Challenge Task 2 of 2

Now that we have an appropriate greeting for our user, let's make a bit more polite by concatenating the greeting string with a second string literal.

Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?".

Example: "Hi there, Ary. How are you?"

let name = "Ary de Oliveira"
let greeting = "Hi there, \(name)."
let finalGreeting = "\(greeting)" + "How are you?"

Challenge Task 1 of 2

In this task we're going to declare two strings. First, declare a constant named name and assign to it a String containing your name.

Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant.

As an example, the final value of greeting could be "Hi there, Ary".

let name = "Ary de Oliveira"
let greeting = "Hi there, \(name)."

Hi, here is my solution:

let name = "Linda" let greeting = "Hi there, (name) ."

I hope it helps.
