Missing .swift_version parameter in podspec

[kaygro]

Expected behavior

When integrating this Pod into a Xcode project in swift 4.2, it should compile.

Actual behavior

It does not compile.

Steps to reproduce the behavior

Integrate this Pod into an Xcode project where the main target's swift_version is set to 4.2.

Podspec should just include the .swift_version parameter in podspec.

I just noticed, this pod doesn't take into account the UIKit renamings that occurred in swift 4.2.

I still recommend, putting the swift_version parameter into the podspec.
I noticed, you already migrated the offending classes to swift 4.2. Would you make a new release then?
