Back in November I talked a bit about my passion project. I’ve rewritten the Pharmacokinetics Math library for RxCalc in C++ and I’m rewriting the UI completely in Swift. It’s been a real blast. My November update talked about bringing C++ and Swift together with a tiny layer of Objective-C++.

Over my holiday break I didn’t code as much as I wanted to, but I did manage to get some done. Since returning to my day job I’ve felt a bit more excited about working on the RxCalc update at night. I don’t know why, I just have.

I now have the new mixed Swift, Objective-C++, C++ based app in a working state, but I have a lot of polishing to do as well as adding some new features. Of the remaining 1.x features I have to implement is Options. Once that is complete I’ll move on to adding IAP, Theme, and 3D Touch support.

I really love working in Swift. The code base feels so tiny compared to its Objective-C counterpart. Not that Objective-C is bad, just different.

Next up? The Android version. For that I need to spend some quality time with JNI.

I’m not in any shape to ship this release, but it’s getting close by the day.
