1,117 PointsIn this challenge, I am confused on what exactly the "multiplier" name is and does.
I understand what "for loops" do, but in this case I am very confused on what the question is asking. And what is the name in the loop?
// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
multiplier * 6
}
results.append(multiplier)

For example, multiplier could be named 'bananas', and the result would be the same!
It's just a NAME given to the value that you are iterating through.
So basically, what happens is the loop starts at 1, and assigns 1 to 'multiplier'. It then goes into the loop and does your code, which is multiplier(which is 1) * 6.
Then the for loop has finished, so multiplier IS DELETED.
The loop then starts again! Multiplier becomes 2, then multiplier(which is 2) * 6.
It then keeps repeating this until it gets to the last value you've specified, which is 10.
Hopefully this makes sense. If it doesn't, please let me know.

1,117 PointsYes ! Thank you that makes perfect sense. But then my code is not working. It is saying I have “multiplier” as an unresolved identifier, and same as the multiplication sign.

8,429 PointsSorry for the late response!
Your ‘results.append(multiplier)’ is being called outside of the for loop. Remember - multiplier ONLY exists in the for loop!
What you could write, is this - results.append(multiplier * 6)
Making sure that it’s INSIDE the for loop
