[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
 - [ ] Link to all referenced talks/posts in README
I've added a todo item to aggregate all of those in the README of this repo when I'm done.
