Good call. I am attaching an implementation of _swift. Though I'd very much like
to parse --help output programmatically, some intricacies (like which options
can be repeated) are simply not visible from --help, so I'm hard coding options.
Hopefully Swift is stable enough that options won't fluctuate much across
versions.

Subject: [PATCH] Completion/Unix/Command/_swift: new swift/swiftc completions
swift(1) and swiftc(1) are part of the Swift programming language.
https://swift.org/
_swift was written against Apple Swift version 3.0.2.
Note that swift(1) conflicts with the command of the same name from OpenStack.
Completion is delegated to _openstack when swift(1) is detected to be from
OpenStack.
