The intersection of technology and leadership

Starting iPhone development

Late last week, Andy Yates got me onto the whole Hello World application for the iPhone. Since then, I’ve been dabbling around a bit more trying to get my head around it. After having studied how people learn things using models such as Shu Ha Ri, the Dreyfus Model of Skills Acquisition, and Kolb’s learning cycle, it’s fascinating to try to understand how best to pick it up.

Here are some observations that I’ve made so far:

  • There are many different dimensions to learning how to write an iPhone application. First, there is the fact that it’s written in Objective C, so you’re learning about the syntax and intricacies of a new language. Secondly, you are learning new development tools including XCode and Interface Builder. Thirdly you are learning about the libraries, documentation, and understanding how things fit together.
  • I intentionally recognise myself as being at Shu level (in Shu Ha Ri) or a Novice (on the Dreyfus Model). This means that I want to have some quick wins, get stuff working and worry about how it all fits together in the next stage. I’ve found that repeating the same exercise (almost like a kata) has helped me understand how things relate to each other just that little bit more.
  • Writing a journal helps. I intend on blogging about some things that I’m discovering. It might help one person out but it will sure help me articulate clearly my understanding (or lack of understanding) about the topics that I’m finding. When I don’t blog, I’ve got a little text file with snippets on what things I’ve discovered and what things still puzzle me. It’s helping me organise the random things that I’ve got.
  • Interestingly, I’m less interested in following some of the practices I would if writing a production application. This means I’m not worrying too much about refactoring or testing until I get the basics down. I don’t want to confuse the concerns of exploration and learning with verifying the system works (which I can barely get going right now). When I am more confident in my knowledge, I’ll definitely spend more time thinking about these things.

    Good intro post for iphone developer noobs. We run an interactive online iphone training course at EDUmobile.ORG that is aimed mostly for newbies. We have noticed that most of the info for iphone development is very scattered around the web. Do have a look at our course, which comes with a 30 days no questions asked money back guarantee.

    In my experience, doing teat-driven development when exploring a new technology lets you document your learning and even refactor that learning as you move to higher levels of grokking the subject matter.

    Then, you can share your tests with others who follow. Like me! 🙂
