Transition to Swift Complete

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.
