Not sure why this second part did not work ?

I am not sure why the code did not work when i tried it as it appeared to work in Xcode?

strings.swift 
// Enter your code below
let name = "Pasan"
let greeting = "\("Hi there,") \(name) \(".")"
let finalGreeting = "\(greeting) \(" How are you?")"

You don't need () for text inside of strings (although it is possible to use it and you still would be able to pass the challenge, the code would be hard to understand and fix). You only need it for variables/constants :)

Try this:

// Enter your code below
let name = "Pasan"
let greeting = "Hi there, \(name)."
let finalGreeting = "\(greeting) How are you?"

Also, you have an extra space before the period (code challenges are super picky, keep that in mind :smile:)

Good luck! ~Alex

Thanks Alexander - that has made it clearer for me in terms of not having to use additional quotations and () for text. However, using it in the code challenge the second part still shows an error! I am convinced i have typed this word for word and i know that it works in Xcode as per what you types. Thanks for your help though.

The error is "Make sure you're using concatenation to create the final string value required!"

Try changing the period to a comma :)

it turns out i messed up as i should have used string concatenation in the last part rather than just having a single string. Passed the test now. Thanks for your help
