Hi Brian!

What Swift is telling you here is that the method that was once named 'println' is now named 'print'. You will find things like this can often change in a language as new as Swift is. Apple are constantly adding new things and also changing older things around so it's important to be aware that not all of the Swift code available online will be compatible with the newer versions of Swift!

I hope this helped you out! If you need any more help then feel free to ask away!

Thanks, I thought thats what had happened.

How can I find out if there is a way to force a Print function to take a new line now that Println doesn't work?

Thanks for your help.

print automatically prints a new line now (I'm pretty sure), so you don't need to worry about forcing it. If you're looking for a new line in other functions in the future, there is a character that universally represents a new line to all functions. That character is a backslash and then a lowercase n, like this: \n
