A few years ago I left my comfortable career of managing the live production environment for churches to study in the new-at-the-time iOS development program at Lambda School (now called Bloom Institute of Technology). I spent basically all day every day for nine months reading and writing Swift and learning how to build iOS apps. Since I finished that program I have worked on a few apps, learned as much as I can, and most recently landed at a company called Hallow. I continue to learn as I go, and I try to document the progress when I can. If you're interested in following along with that, checkout dilloncodes.com.
