Apple ResearchKit: how to extract information from ORKResult? First time programmer

I'm working on a simple ResearchKit app that has 20 survey questions, or ORKSteps. How do I get the answers from a participant who submits the survey into a database?

My research has found ORKESerializer and SQLite as potential parts of the solution. I'm missing a big picture view of how these things can be integrated into a working solution.

Starting without knowledge of databases or data transfer from Swift, so any basic information would be very helpful.

1. How do I extract data from ORKResult using Swift?
2. Where do I extract the data to? Or, what's the standard type of database for a small survey?
