Podspec / Release out of date

[traylewin]

Hi there. Love this project and the quality of the code! Can you do us a favor and release a new version with the latest changes? The current podspec and release tags cause an older version of the code to be installed (pre Swift 3) Thanks!

Bumping this request. I can make the new podspec if you'd like @klaaspieter?

#33 should do it. I'll push it when I get pod trunk access.
