+1 for using "case _" instead of "default". It communicates programmer's intent clear and loud. Also it didn't occur to me to use it. :)

>>> 1) We have had default and “case _” ever since Swift has been public. If you look at bodies of existing swift code, they almost unanimously use “default” instead of “case _”. This argues that default is more familiar and more widely used. It isn’t some legacy barnacle on the side that people generally ignore.

If the documentation was written using "case _" I think we would see that be the familiar and widely used variation.
