* Many functions will now throw instead of returning an NSError * I have run these in a separate demo project, but not as part of the main project (Cocoapods/testing woes continue). If you want to run these tests standalone, I've put them in a Gist here https://gist.github.com/matthewpalmer/17f54354a710828ec193 * Most of these tests use try!, though they could probably be improved to use do/try/catch
