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, Linda".

strings.swift 
// Enter your code below

let name = "john"
let greeting = "hi there"
let interoplatedgreeting = " \ (greeting), \ (name)"

Can't seam to get it right :(

Hi Alfredo!

You are simply not doing what the question is asking you to do.

Firstly, it asks you to declare a constant named name and assign it your name which you have done so correctly:

let name = "John"

Then, it asks you to create a constant named greeting with an interpolated string:

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

You have added the greeting string but not interpolated the constant name.

In the second tasks it asks you to use string concatenation:

let finalGreeting = greeting + "How are you?"

Overall the solution to both tasks should like like this:

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

Essentially you are using different constants to create sentences both with string concatenation and interpolation.

I think it would be best to rewatch the video to increase your understanding, perhaps writing things down, and then just try again!

All the best, and have fun coding!
