Courses Plus Student 7,494 PointsHi Peter,
If you take a look at the Apple Documentation for URL object: https://developer.apple.com/documentation/foundation/url
The reason it returns an optional is because the initialiser for the URL object, that takes a String is a fail-able initialiser. This is because in reality any String can be based to the initialiser, and it may or may not be a valid URL. In the case that it is not valid, it will return nil. E.g. let url = URL(string: "hello world") would return nil, as "hello world" is not a valid URL, though it is a valid String.
Hope that makes sense.
Ian
