Courses Plus Student 13,389 PointsIt seems that the Xcode Documentation API reference does not always show code that is deprecated (No longer used). I have found that using the online resource
https://developer.apple.com/library/ios/navigation/
is more current and up to date.

Try checking if you have the stringWithContentsOfURL in square brackets. For instance, in Objective-C, [NSString stringWithContentsOfURL:]. Since it is a class method, method has to be in brackets.
In Swift, you probably would do something like, theString(stringWithContentsOfURL..........)
But it's kind of hard to tell without seeing the code.
There's also a possibility that it might be an Xcode bug. I have faced instances where, my code doesn't autocomplete for anything.
