Thanks! I taught myself to code in high school, mostly by messing around with little Flash game experiments with Actionscript. In my senior year of high school I taught myself Objective-C and built an iPad app for a summer internship (https://itunes.apple.com/us/app/north-star-smart-stars-surve...). I didn't learn iOS game programming specifically until college, where I participated in a one-month class/competition that taught the Cocos2d game engine.
