I’m gearing up for more iOS app development in the near future, and in the pursuit of clean code I decided to start sketchnoting a recent video series from Lynda.com – iOS SDK Essential Training (2012).  The sketchnotes above are from the Objective-C Refresher section of the course, which provided a helpful recap of the big ideas of the Objective-C programming language as well as recent updates (such as ARC – automatic reference counting) which were not around the last time I was programming on a regular basis.

The notes were created using the iPad app Adobe Ideas, which I am a big fan of.  I’m also a big fan of Lynda.com, which is a continually-updated and ever-expanding series of online video courses geared toward developing technical skills, with topics as basic as how to use a word processor all the way up to complex computer programming.  They’ve also got a great set of documentaries that highlight the life and work of a variety of artists – I have turned often to those documentaries when in need of inspiration, and I rarely walk away disappointed.  Over the past two years I’ve used the membership (which is reasonably priced at $25 per month) to learn about topics related to computer programming, online teaching, and website development.  I recommend checking it out to see if they offer courses that fit your needs.
