948 Pointsconcatenation mistake or bug?
I am doing Swift 2.0 Basics and I am learning about concatenation. I have tried everything I have learned so far for this method and still I can't get it right. The error message I get ays to make sure I am using concatenation, which I am.
Could someone please help me in finding out how I could concatenate better? My code is below
// Enter your code below
let name = "Valeria"
let hi = "Hi"
let there = "there"
let greeting = "\(hi) \(there), \(name)."
let stringLiteral = "How are you?"
let finalGreeting = "\(greeting) \(stringLiteral)"

Concatention is adding the strings together using the plus sign. What you've done there is interpolation.
So, finalGreeting should be made up of greeting + " How are you".
Something like this should get you through the challenge:
// Enter your code below
let name = "Steve"
let greeting = "Hi there, \(name)"
let finalGreeting = greeting + " How are you?"
You start with name holding your name, then interpolate that into the greeting constant. Next, you concatenate greeting with the additional string " How are you?" by adding them together using the + operator.
I hope that helps,
Steve.

\()when using string interpolation. All static parts are just like regular strings. See Apple docs.Steve Hunter
