[WIP] Swift reboot

Updating presentation for Swift, and trying to address the feedback in #21. Anything in all caps is a note for myself about something that still needs to be done.

The presentation itself is in [Deckset](decksetapp.com) format now, intended for use with the “Next” theme.

- [Rendered PDF](https://github.com/jspahrsummers/enemy-of-the-state/raw/reboot/Enemy%20of%20the%20State.pdf) (does not include presenters' notes, and may be a couple revisions behind)

Comments welcome! :heart::bow:

**To do:**

 - [ ] Add code samples where missing
 - [ ] Add presenters' notes where missing
 - [ ] Audit apostrophes and quotation marks
 - [ ] Think hard about ordering
You might consider giving a few examples of abstractions that people are familiar with to help them feel comfortable. "I want to tell you about this thing that has some of the same benefits as these other things that you know, like, and are not afraid of."
