If I’m remembering correctly, the original reason for this was because this was meant to be a part of Foundation. Now that this is in the Standard Library, however, it seems strange that we’re still using NSError.

> To answer your second question, the reason is that using the protocol implies that all encoders and decoders must support anything that conforms to that protocol. We’re not sure this is a reasonable requirement. Many formats do not have any kind of support for arbitrary size integers, for example. Therefore, we felt it was best to limit it to a set of concrete types.

>>> The review of SE-0166 “Swift Archival & Serialization” ran from April 6...12, 2017. The proposal is accepted with some minor modifications. Specifically, the core protocols and types will be sunk down into the Swift standard library for more tight integration with the Swift language and compiler, and the operations specifically involving Foundation’s “Data” type will be removed. The proposal document has been updated with more detail. Thank you everyone for participating in this review!
