While far from the rich array of run-time hackery familiar to seasoned 
Objective-C developers, Swift's tools enable the immediate feedback and 
sense of exploration offered by Xcode Playgrounds. This week, we'll reflect

Twitter falls back to og:description if there is one (which is preferable 
as an open standard used by several companies), and Open Graph is RDFa so 
in theory this has the same meaning:

<span property="og:description">Reflection in Swift is a limited affair, 
providing read-only access to a subset of type metadata. While far from the 
rich array of run-time hackery familiar to seasoned Objective-C developers,

Swift, its mirror types, and `MirrorType`, the protocol that binds them 
together.<span>

without requiring you to duplicate the text of the lead paragraph. No idea 
whether all Open Graph consumers really understand it, though.
