At SonoPlot, we just undertook a full rewrite of our robotic control software from Objective-C to Swift. While at first it might appear crazy to rework a large, stable project in a brand-new language, we did so after carefully examining sources of bugs in our Objective-C application and determining that Swift would prevent a large percentage of them. While we've only just started, we've learned enough so far that I thought there would be value in sharing this.
Read on for more about what led us to rewrite this application, and what we observed when doing so.
