What's the deal with optionals? I am not sure what the use case are.

Seems much better then ObjectiveC

The docs seem to cover it pretty well: https://developer.apple.com/library/prerelease/ios/documenta...

But the basic idea around optionals is a much better and cleaner way of dealing with possible null (nil) values. Lots of other languages have and are getting optionals.

What was confusing me that they would specify it during initialization.
