Looping Over Ranges: for number in 1...10 trouble.

I have just upgraded Xcode to 7.3.1 to Swift 2.2. I am not sure if this has anything to do with my problem, just thought it might be helpful.

I have been following along with the video and have came across a few errors in the first Range Operator. Here it is:

for number in 1...10 { print("(number) times 5 is equal to \ (number * 5)") }

Here are the errors I have been getting:

-Expected ',' separator -Invalid escape sequence in literal -Unterminated string literal

Can anyone help me out? I feel ridiculous.

It looks like you have a syntax error : 

for number in 1...10 {
      print("\(number)  times 5 is equal to \(number * 5)") // **\()** <- missing a blackslash 
}

I also had this same issue, and found that in the video the code has a line break after the \ before (number). Putting everything on one line fixed my errors.

So the way Gary posted was the correct syntax over the lesson.
