New Winter Book Club Info

Our Book this term is Swift Coding Challenges by Paul Hudson. Chock full of fun, enlightening, and stimulating puzzles and problems, you won’t be able to stop yourself from reaching for the next one.

Whether your goal is to level up in Swift or get ready for your next job interview, I can think of no better preparation. I started each day with a new Swift Code Challenge as a way to get myself in the right head space for coding.

Book Club sessions will be interactive and fun as you present your solutions and review each others code - looking at simplicity, performance, and ‘Swift’iness. There is no barrier to jumping in at any time as the challenges are completely independent.

The ebook can be purchased for $20 at:

Book Club will be every Tuesday at 8PM. First meeting, Tues, Jan 10th.

CocoaHead Meeting Changes

New Start Time

We are changing the meeting times for our main, second Thursday of the month, meeting.

Doors will now open at 6pm (was 6:30pm) for pizza and socializing. The meeting itself will start at 6:30pm and we’ll shoot to end the meeting at 8:30pm (was 9:00pm). The goal of this change is to be a better guest of Apple and provide their cleaning crew enough time to restore the Briefing Room before the store officially closes.

Please continue to RSVP via

Presentation Etiquette

To help make sure we keep our agenda times, we will now ask that people hold their questions until the end of the presentations, and then give them only when time is available. This should help people stay closer to their planned script as well as make sure everyone on the agenda, including the final speaker, has the expected time to do their presentation. The leadership will make some changes to how we display our timer so everyone is aware where they stand.

If you’d like to present in 2017 contact

Your Feedback Welcome

If you have any feedback on these or other changes / additions you’d like to see come in 2017 from CocoaHeads, let the leadership know. We may have some extra funding for something new and we welcome your feedback on what that should be.

Thanks for your continued participation in our local Apple developer community.

CocoaLove Conference 2016

Its back for another year!

For anyone who has never heard, CocoaLove is a conference that brings the Apple community together and focuses on talks that aren’t deprecated at the next WWDC. It’s structured to build meaningful connections throughout the weekend that are more than just a stack of business cards. Join and enjoy a unique Philly experience.

After the huge success with the new scholarship program last year, they’re bringing it back! Are you a woman, minority, single parent, LGBTQIA, or disabled individual? Read more and learn to help make CocoaLove more accessible to you. If you’re considering attending CocoaLove this year please consider donating towards the scholarship fund.

Speaking of “if you’re planning on attending” early bird tickets are now on sale! Like, right now. It can be hard to sell employers on business trips later in the year, especially in the later summer after the massive WWDC’s expense has hit, so they wanted to make sure you have the best odds of attending by opening up sales much earlier than normal.

Details can be found here:

Overview of how the SnipSnap team was able to build a complete chat based product in two months.

Promises for the Future, Andrew Theken

Asynchronous programming is a cornerstone of creating responsive applications. There are many patterns that have been tried over the years to help programmers write async code without losing their minds. One particularly elegant pattern for dealing with the async operations is called “Promises” (or ‘Deferred,’ or ‘Futures’). PromiseKit is a framework that makes it easier to write async code, allowing you to to keep a more linear flow in your async code. I’ll cover some of the basic use cases for PromiseKit and how they can make your OS X or iOS applications easier to build and maintain.

Load Testing, Richard Friedman

Record mobile api calls on iOS using Apache JMeter and then play them back scale it out to simulate hundreds or thousands of users.
