Is there really no way to specify default values for #swift #Codable #Decodable keys? Like, if a JSON key is missing, provide a default value for a struct’s property, without having to write a custom `init(from:)` initializer?

That makes it hard to dot-version rev a schema by adding keys, but continue to maintain backward-compatibility with older saved data…

This is so unexpected, but amazing

Is this weird? Or normal?

I needed a type which is codable so I can archive/transmit it in various ways, which boxes a result with noncodable types.

More work on my app.

Been trying to set it up so #CoreData objects can be created and updated from the objects sent from the API using the #Codable protocol.

It has had its headaches but I got it mostly set up, even to the point of updating existing objects in the data store.

My issue comes when I hit a collection of objects. I’m not sure how to handle inside of the init(from: Decoder) when some or all of those objects are already in my store
