FMDB was just updated to version 2.7. From What's New in FMDB 2.7:

"FMDB 2.7 attempts to support a more natural interface. This represents a fairly significant change for Swift developers (audited for nullability; shifted to properties in external interfaces where possible rather than methods; etc.). For Objective-C developers, this should be a fairly seamless transition (unless you were using the ivars that were previously exposed in the public interface, which you shouldn't have been doing, anyway!)."

Rob Ryan did pretty much all the work on this release, so if you use FMDB in Swift, he's the guy to thank.
