Subject: [PATCH] Performed conversion to Swift 4, with recommended Minimize
 @objc Inference option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Xcode 9.4's conversion to Swift 4 made minimal changes for this lib, really just changing the `SWIFT_VERSION` build setting to `4.0` (it made that change on the target; I moved it to project-level).  No additional `@objc`s or whatnot were required.
