[swift-users] Why can't we get `URL` equal on the same path?

In our case, if we accidentally send a URL from the server with a trailing
slash, we want that to be equivalent to one without. But yea, if you're
manipulating it you might have more problems! Although in our case we add the
slash for the case without it.
