Issue Description:

Swift seems to be forcing me to replace some `nil`s with `.none`s today, whereas Swift 4.2 is fine with `nil`.

Thanks for filing!

This is very interesting, for some reason conversion from `((Verify) -> Void)?` to `Process<Verify>?` fails.

Just checked the sample on Xcode 11.4, seems to be fixed already so I think this could be resolved cc @xedin

Thank you, @LucianoPAlmeida! Looks like this indeed has been fixed in Xcode 11.4. Jessy (JIRA User) Could you please verify?
