The transition to swift is now complete. All the functionality from Objective C is now in Swift. It took me a bit longer than expected, but it was fun learning a new language. I started with Swift 2.0 and iOS 9.3. Part of the longer time was because while updating Swift 3.0 and iOS 10 were released. I didn’t find a way to implement the statistics tab that worked for both iOS 9 and iOS10. And I didn’t want to leave my iOS 9.3 iPad users without an update.
