Alli Semans
723 PointsDo not understand why work is not right
I typed my answer into XCode and it said it was correct by saying, "Hi there, Alli." I copied and pasted it into Team treehouse and it said it was incorrect. I am unsure how to fix this to resolve the problem.
let name = "Alli"
let greeting = "Hi there,"
let interpolatedGreeting = "\(greeting),\(name)"

Treehouse TeacherHi there! There's a few problems here. Yes, your code works, but it doesn't exactly match the requirements of the challenge. First, you seem to have changed your greeting constant from what passed in the first step. Secondly, the last constant is supposed to be named finalGreeting not interpolatedGreeting. Third, the challenge explicitly asks you to use concatenation on the final step. But you've used string interpolation.
Remember, concatenation is combining two or more strings with a plus sign. Interpolation is the use of backslashes and parentheses to insert the value of the variable into that spot.
Take a look:
let name = "Alli"
let greeting = "Hi there, \(name)."
let finalGreeting = greeting + " How are you?"
Hope this helps!

173 PointsSame problem as Alli. There is an issue with this second challenge. Nowhere is mentioned that it needs to be a concatenation, on the contrary it only says that it has to be an interpolation.
Should be fixed by the Team Treehouse Team!

173 PointsThe issue is at the second step.

Treehouse TeacherHi Xavier Fricker!
This is a direct quote from the first step.
Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant.
Note that they explicitly say that the value in the greeting variable needs to contain an interpolated string.
This is a direct quote from the second step.
Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?".
Here, they explictly say to "contatenate the value" and store it in finalGreeting.
And here is a direct quote from you:
Nowhere is mentioned that it needs to be a concatenation, on the contrary it only says that it has to be an interpolation.
This is simply not accurate.
Happy coding!

Yes, and that is the part that was not working. I did exactly that' just like you showed explained and it didn't work.

Treehouse TeacherI really don't know what to tell you. If I copy/paste the code I wrote above in the challenge, it passes both steps. Try restarting the challenge and copy/paste my code in there.
