iOS Swift Basics Swift Types String Manipulation

I'm typing the same code into my xCode and it comes out as "Hi there, Denonte". Why doesn't it work in the template?

// String Concatenation let greeting = "Hi there" let name = "Denonte"

// String Interpolation let interpolatedGreeting = "(greeting), (name)"

strings.swift 
// String Concatenation
let greeting = "Hi there"
let name = "Linda."

// String Interpolation
let interpolatedGreeting = "\(greeting), \(name)"

There are many ways you can arrive to a solution, but often times Treehouse is looking for something very specific. For example, the task wants you to use string interpolation in the greeting constant. Instead, you created a new constant that Treehouse wasn't expecting:

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

As a note, your comment says "string concatenation", but you never actually did any string concatenation. String concatenation is when you add two strings together. For example:

let name: String = "Linda"
let greeting: String = "Hi, "

let fullGreeting: String = greeting + name + "."
// Hi, Linda.

Also, for task two keep an eye out for string concatenation as well as string interpolation. It wants you to use string concatenation and string interpolation together. Many people don't see these instructions the first time through and forget to use string concatenation.

I tried the code a bunch of times and different times but it still didn't work. Theres a special requirement from the "finalGreeting" that i'm not meeting and I don't know whats the issue. :(

Hmm maybe there's an issue? Whats your new code? The following works for me

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