WWDC 2013

I attended my first WWDC this year and it was an excellent week.

The highlights:

  • OS X Mavericks
  • the new Mac Pro
  • iOS 7


Compilier Alignment issue

I received some help for an odd bug I had been hunting for awhile. Turns out it was an alignment issue.

Xcode App Versioning

Received some feedback on my process for auto versioning within my apps.

Simply Cocoa

I will be heading to Cocoa Conf in Chicago next weekend. I am looking forward attending another iOS Developer conference and meeting fellow iOS developers.

The Cocoa Conf schedule is packed with many sessions that I find very exciting. I am going to try and concentrate on a few of the animation and graphics session since I have been digging more and more into openGL in one of my Master’s Degree courses this semester.

Sessions I attended:

  • UI Automation – Testing from the top down. Jonathan Penn

  • Objective-C Runtime: Fun Under the Covers

  • Getting started debugging with Xcode

  • GLKit: Why you should care

  • Visualize You Data With Core Animation

  • Understanding OpenGL ES 2.0 shaders

  • Keynote: Your Code – the Director’s Cut

  • Enter the Matrix

  • Blocks^

  • Reverse Q & A Panel

  • Styling and Composing your UIViews with CALayers on iOS

The biography about Steve Jobs came out today and I have started reading the first couple of chapters. So far it is a great book and hard to put down. I highly recommend anyone who has interest in entrepreneurship, technology, or leadership that they read this book.


Just finished up with four days of information packed sessions about all things iOS Design, Development and Business at 360iDev.

The event ended up having about 355 attendees, so it was a much smaller conference than either of the previous GoogleIO conferences I attended.

The conference actually began with a day long Pre-Conference training session. Some of the topics included Advanced Debugging, OpenGL ES for Image Processing, iOS 101, OCMock, and Prototyping Native Mobile Apps.

Here is the link to a list of speakers that were there.


I decided to go a little out of my comfort zone and choose a more design oriented track so I took the ‘Photoshop for Devs’ with Mike Berg. It was a great day packed with tons of great tips.

I attended MagicRuby February 4-5, 2011. It was a conference that centered around the Ruby Programming Language. I stumbled across this opportunity somewhere on twitter I believe and thought it would be a catalyst for my goal to become more efficient in Ruby. I knew that Dave Thomas and Chad Fowler were giving keynotes, but I didn’t think their keynotes would be more about software development than Ruby. I thought both keynotes were inspiring and am going to watch for other conferences they are going to be at.

An overview of the sessions

Cultivating Cucumber

Les Hill, Hashrocket

Slides I have become more interested in Test Driven Development since I attended CodeFreeze at the UofM, so I will defintiely look more into Cucumber which describes itself as Behavior Driven Development.

Geospace Your Ruby

Peter Jackson, Interidea

Slides This talk was all about Geospacing your applications. I was surprised how much data there is available out there and I know this could be leveraged in almost any application I write.

Loving your customers, loving your peers

Alan Johnson, Carsonified

Documentation is freaking awesome

Kyle Neath
