Build a SQLite Framework in Swift

Last time we saw how to wrap a Swift framework around a C library and talked about how that could be used in an Objective C app (a design pattern I'm calling "the turducken"). This time we'll see how to do that with a SQLite-based cache to build a simple geo-tourism app that lets you save and display locations along with titles and notes. This will set us up nicely to do sharing and iMessage extensions to make it easy to share these with your friends, which we'll do in October.
