Xcode 8 beta 4 URL with empty string

URL(string:"") now returns nil.

" /// Returns `nil` if a `URL` cannot be formed with the string (for example, if the string contains characters that are illegal in a URL, or is an empty string)."


This worked in all previous betas and versions of Xcode as far as I know and was supported:

"An empty string is a valid URL string. It has no scheme, no authority (user/password/host/port), an empty path, no query and no fragment."


So how do we create a URL with an empty string now?
