You probably want to check out this repo: https://github.com/Zewo/Reflection <https://github.com/Zewo/Reflection>

It's clever stuff. Really, really reliant on implementation details of the runtime to function, so I'd be loathe to use it in any sort of production application, but as a proof of concept it shines.

Hope that helps,

It is key to enabling the Xcode 8 memory visualization / debugger feature, and is a fundamental building block for a data reflection API.  In fact, if I recall correctly, a 3rd party framework already build a custom data reflection API around this metadata already (Zewo?).
