Dates and Times in Cocoa

New Location! Arbormoon Software has moved, and so has the meeting. 123 N Ashley, Suite 9, on the lower level is the new location.

Starting at 6:30pm, we'll have free food sponsored by Arbormoon Software, Inc. Please RSVP to help us estimate how much food we need. While you are enjoying the food, talk with other developers and network in the local Cocoa community.

Our main meeting will start at 7pm and will feature a talk on Dates and Times in Cocoa by Jeff Kelley.

Date and time APIs are notoriously difficult, even though we all have an intimate understanding of the problem domain. Why is it so hard to get right in an app, yet so easy to reason about? How could Apple screw up alarms around Daylight Savings Time more than once? In this talk, we’ll take a tour of the time and date APIs in Cocoa and Cocoa Touch, solve some common problems, and figure out why things aren’t always as easy as they seem to be.

Jeff Kelley is an iOS developer at Detroit Labs and author of Learn Cocoa Touch for iOS, published by Apress. He’s been working with iOS since its infancy in 2008, and managed the OS X environment at the University of Michigan before that. Apps he’s worked on that you’ve likely seen are the Domino’s Pizza iOS ordering app, the award-winning Chevy Game Time second-screen Super Bowl experience, and the DTE Energy outage center app. When not working on iOS apps, Jeff listens to an inordinate amount of podcasts and seeks out new and interesting races to run, recently completing his first half marathon.
