[Answered] Why are these _JSONKey initializers failable?

[NSExceptional (Tanner Bennett)]

Code in question. Seems like these shouldn't be failable

These initializers are inherited from the CodingKey protocol, which defines them this way. The conformance could drop the optionality and still conform, but given that this is a fileprivate struct, I don't think it matters much either way.

Ah, I see. Just wondering, thanks!
