Becoming an iOS Developer

I found a nice, straightforward post by Josh Smith about becoming an iOS developer with a background in other technology stacks. He did a great job laying out the basics; I’m not going to really re-hash it, but add my feelings on the matter.

As someone with a background in .NET and Java (among others) I can definitely feel where he’s coming from when he says:

I warn that it will take a considerable amount of time, effort, and patience to get over the learning curve. If you think that going from WinForms to WPF requires a major mental adjustment, you ain’t seen nothin’ yet.

He’s not lying! Through my years of application development experience I’ve become completely comfortable with the whole MVC pattern and many abstract concepts of ‘good’ application design. I’ve found that all (or at least a lot) still apply to the iOS development world, but the execution is so far different than what you’ve done on (probably) any platform that it’d almost be better starting from scratch. Almost… maybe.

I bounce between Visual Studio, Komodo IDE, and Eclipse every day for various languages and products. I use vim, Notepad++, and TextWrangler just about every day (I dual boot Win7 and OS X and bounce between both, all my servers are Linux). Getting used to yet another IDE seemed like a pain, but Xcode 3 was pretty okay. Nothing though, threw me for a loop like the upgrade from Xcode 3 to Xcode 4; with the introduction of segues, moving Interface Builder into the IDE, ARC, and a number of other things. I’m still finding new things every day. It’s a much better IDE than Xcode 3, yet still hasn’t got much in the way of going toe to toe with Visual Studio.

Apple expects developers to be smarter than Microsoft does. Microsoft works hard to ensure that programming technologies are usable by as broad a range of people as possible. Their tooling and documentation assume you aren’t quite sure what you’re doing. Apple, on the other hand, is not nearly as helpful and pandering.

Whether it is that Apple wants to weed out some of those VB6 types, or just assumes that you’ll figure it out- they certainly do a lot less pandering to the least common denominator.

Final Thought

I love developing for iOS. It is a pretty homogeneous environment, Objective C lets me flex some of those C muscles I haven’t flexed in years, I can pretty rapidly get test ideas and wireframes alive enough to experiment with, and it’s another feather in my cap.

If you’re just starting out, turn off ARC, get used to managing memory on your own, and prepare for a lot of initial frustration if you’re used to picking up languages as easy as I have.
