8,568 Points\n in Swift2,
\n no longer makes a new line in strings...is there a way around this?
James Gray
8,568 PointsSo what i'm gathering is that this is not longer an operation that can be carried out with the update to swift. Xcode is now running swift2 and that comes with several changes. not only is the \n in strings no longer being taken, println and print were merged into one more convenient statement of just print. I'm sure there are many more changes that we will run into seeing as how the language is still new.
Just carry on learning swift2 using the lessons they provide on Treehouse and when it comes to quizzes and whatnot on treehouse just make a mental note that the syntax they want you to carry out is what you saw in their video's even though it's slightly different when you're actually in Xcode.

8,568 PointsFrom what i've gathered in swift2.0 the normal print function adds in the \n character unless you add in terminator: "" after what you're printing such as print("Hello", terminator:"")
i'm not entirely sure though hopefully this helps some.

8,568 Pointswouldn't that be redundant as it would say that you have two \n's? on the debugger pain it's not going to show either, however in the bar on the right it will say \n\n

5,597 PointsTechnically you can use \n still in strings. I would not say adding \n to strings is redundant. While the new print function does automatically add an \n there are times when someone will want a second blank line after using the print function. From the question above it seems like Faisal still wanted to add a \n to his string. Hopefully the confusion has been cleared up now. :-)
