This is perfect, thank you! And it is comforting to see that so much thought 
went into these decisions ...

To expand on this, most (if not all) the proposals in the list of proposals
on GitHub (https://github.com/apple/swift-evolution/tree/master/proposals)
have a "Rationale" link to a mailing list archive post by one of the Swift
core team members explaining why a certain decision was reached. Those are
probably worth looking through. Some of the simpler and less controversial
proposals have almost no explanation, but the larger and controversial
proposals have extensively written-up rationale posts.

Best,
Austin

Re: [swift-users] Justification for Swift Design Decisions?

[David Sweeris via swift-users]

Specifically WRT to double quotes for characters, the Commonly Rejected Changes 
doc (https://github.com/apple/swift-evolution/blob/master/commonly_proposed.md) 
says, "Swift takes the approach of highly valuing Unicode. However, there are 
multiple concepts of a character that could make sense in Unicode, and none is 
so much more commonly used than the others that it makes sense to privilege 
them. We'd rather save single quoted literals for a greater purpose (e.g. 
non-escaped string literals)."

Otherwise, off the top of my head I'm not sure. If it's a particularly 
controversial decision, there's a fair chance it's come up on the 
swift-evolution list, though, so maybe search its archives?

Hope that helps,
