2,919 Pointswhat is wrong with my code?
it keeps saying "Make sure the value you are assigning to greeting is an interpolated string" my output is correct and reads "Hi there, Jay. How are you?" but it's not letting me pass the task. Have I incorrectly set out my code?
// Enter your code below
let name = "Jay."
let hello = "Hi there, "
let string = " How are you?"
let greeting = "\(hello) \(name)" + "\(string)"

let name: String = "Jeff"
let greeting = "Hi there, \(name)"
let finalGreeting = "\(greeting)" + "How are you?"

The greeting the task asks for only includes "Hi there, NAME" and nothing beyond that. By adding more to the greeting your code will be marked as wrong.
Also you don't need to split the greeting into so many variables. An interpolated string can contain both regular text and placeholders. So you can achieve the task with only two lines of code like this:
let name = "Jay"
let greeting = "Hi there, \(name)"
It's also worth noting that using the + operator is an example of string concatenation rather than string interpolation. So you use both string interpolation and string concatenation in your code. Which is not really a problem normally (though a bit redundant) but for this challenge they specifically want you to use string interpolation only.
Edit: Added note about string concatenation.

2,919 Pointslet name = "Jay"
let finalGreeting = "How are you?"
let greeting = "Hi there, \(name). \(finalGreeting)"
So i've changed my code to this but it needs to be concatenated. The error shows as: make sure you're using concatenation to create the final string value required!.
how do I change it to the correct format?

2,919 PointsWrite it out as follows and it should work, let me know how it goes.
let name: String = "Birdy"
let greeting = "Hi there, \(name)"
let finalGreeting = "\(greeting)" + "How are you?"

2,919 Pointsit said on the task to use the constant finalGreeting so had to name it that.
And you don't need to write out string with the semi colon because Swift automatically recognises the type you are using, I just did it for practise.

Courses Plus Student 641 PointsThanks your code helped a lot but I don't understand why we used final instead of interpolated and why you said name: and then type string?
