192 PointsString Interpolation
I don't understand why it is not able to compile my string in the code challenge, according to the instructions I am to declare only 2 constants. The first constant being named "name" with a value of my name (Angel). The second constant being an interpolated string named "greeting" with a value of "Hi There, Angel". The way I have written the code seems to be the logical way to me to create the constant "greeting" have the value assigned to it of "Hi There, Angel" without first assigning the value of "Hi There, " to the name "greeting". If I do it that way then it won't let me change the value of "greeting" to an interpolated string.
Help please.
// Enter your code below
let name = "Angel"
let greeting = "\("Hi There, ") \(name)"

You have a few issues with your code, only one of which is causing your code to technically fail the challenge.
The first issue is that you are not being asked to evaluate "Hi There ," as an expression, but that is what you are doing by putting the string literal inside the \(). The syntax \() is used exclusively to evaluate some code inside a string, if you just want to have text inside a string, you just put it inside quotes.
The second issue is that your string literal is wrong. The challenge tells you to use the text "Hi there, " but you have the text "Hi There, ". On this occasion, the challenge checker is passing you despite having a different string. You should not expect to be so lucky in future challenges.
The next issue (and the one that is actually causing you to fail the challenge) is that you have two consecutive spaces in your string and the challenge only wants one. Your first space is in the string you are evaluating ("Hi There, ") and then right after you close the \() you add another space. When the compiler reads the following:
"\("Hi There, ") \(name)"
It converts \("Hi There, ") to Hi There, and \(name) to Angel inside your string, so greeting ends up being:
"Hi There, Angel"
Hope that clears everything up for you,
Cheers
Alex
