Why are we using NSURL for a string to a URL? Can't we just make it a plain string? Also, what's "NS" mean? I know we've been using it frequently.

Tony, NS is an acronym for NextStep.

NSURL is a class from which you can create NSURL objects. Here's the Apple documentation: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSURL_Class/

Yes, the URLs we are accustomed to are String objects. But NSURLs are not. Why? Mainly because NSURL objects have properties and methods Strings don't.
