Dates and Time By Example

Have you ever had a bug that dealt with dates and times? Dealing with time zones, Daylight Saving Time, and the like can make the hair on the back of even the most experienced developer's neck stand up. We all know how to tell time and how calendars work, and yet these bugs are terrifying. Why? Using Swift as a lens to walk through common problems, we’ll explore writing date and time code that’s correct and easy to understand. You’ll leave with an approach to solving calendrical calculations without fear, new tools for handling these problems in your code, and a huge appreciation for the people behind the libraries that make this possible.
