RFC: The Future of ZippyJSON
From my benchmarking, JSONDecoder performs similarly (and often a bit faster) than ZippyJSON for iOS version 17+. For my users, I'm curious if there are still use cases where using ZippyJSON over JSONDecoder is desirable once they've set their minimum version to 17+ (cases where it's still faster, etc.). Otherwise, I will probably put up a notice informing people about Apple's new JSONDecoder performance, and in a few years when every app is on 17+, archive the repo. To all who see this issue, feel free to comment with your thoughts!
As a side note, I would love to take this as a challenge to optimize my project more and still provide a large speed boost over Apple's latest and greatest, but a lot of the overhead now seems to be concentrated in Swift runtime overhead, with stuff like protocol conformance lookups. This is, I think, why Apple's version and mine are now similar, and I imagine neither will change much now unless the runtime performance changes.
I haven't measured it, and don't plan to. But if someone does, feel free to post the results
I'm curious what does iOS 17+ version mean: Is this minimum deployment target or OS version at runtime?
Phones on iOS 17+ will see a faster JSONDecoder regardless of the app’s min version. Companies that support older versions, though, may want to keep ZippyJSON until their min version is 17+.

I still use the library on projects which deploy < iOS 17 for the fixed handling of Decimal decoding, which round trips through Double on older Apple OSes.
