Over the past 2 months, we have been working on using Apple SourceKit for retrieving exact method and property declarations.
This means that method and property declarations (as well as their usages) use exactly the same syntax as you can find in Apple documentation and headers for all iOS and Mac OS X, tvOS and watchOS libraries!
As an added bonus, using SourceKit allowed us to retrieve precise type information for all built-in API's.
For the nearest time, we'll focus on using this type of information for type conversions, as well as considerably improve support for optionals.
Although we have extensively tested the new version,
if you find any obstacles - feel free to report at firstname.lastname@example.org.
