How My Code Has Improved in Three Years

Some Learnings from RaceRunner

RaceRunner is a run-tracking app I wrote in Swift three years ago. This app got my foot back in the door as a professional software developer, and I continue to use it. Since RaceRunner’s release, I have periodically updated the code to support new versions of iOS.

I’ve heard some software developers say that they can’t bear to look at code they wrote a long time ago. There are aspects of RaceRunner that would not pass my own code review today. But rather than being embarrassed by or ashamed of how I wrote RaceRunner, I find that a review my old code illustrates my improvement as a software developer. This improvement elicits both pride in how far I have come in three years and excitement at how far I might go in the next.

The purpose of this blog post is to examine this improvement through the lens of one part of one source file in RaceRunner.
