Issue Description

When do you anticipate a release to support Swift 4.2? Currently I have had to direct my pod file to compile Snapkit using Swift 4 to get my project to run.

@jkiley129 can you explain further? the project compiles fine using Swift 4.2 or Swift 4.0 (it has #if flags) and should be fine?

Any plans for supporting Xcode 10 and Swift 4.2?

Released with SnapKit 4.2.0

I updated pod to pod 'SnapKit', '~> 4.2.0' but still cannot build the project.
