Tutorial. Swift 4. iOS 11.2: AlertController (Tutsplus)

This tutorial first appeared in it’s Swift 3, iOS 10 format here. I’ve since converted it to Swift 4, iOS 11.2.

Shamelessly copied and placed here because here I can keep it handy.  So to the code.

 This tutorial does one thing. It shows you how to use alerts to control actions and to alert the user when something is happening.

The repository for the converted code can be found HERE at this link on my Dropbox Repo.

All other license details etc pertaining to the original are still in place in the zip archive.
