Silver Swift: Rules/Guides one to follow coming from Apple Swift

I wish I have a list, about Apple Swift & Frameworks coverage wrt Silver Swift.

So I have started one, Feel free to Add new rules or update if you find any mistakes from my part.
The rule have to include the solution too.

  1. Silver framework extracts headers from Obj-c not Swift, so use Obj-c API (the swift way) reference from apple doc’s.
