simple inheritance

[robaho]

Is there any way to do this?

@Codable
class A {
   var name : String
}
@Codable
class B : A {
   var location : String
}

@Codable
class Container {
    var elements[A] = [ B() ]
}

How do I annotate this so that when Container is decoded the correct instances of A/B are instantiated?

I got dynamic coding with a protocol working but I'd rather not use that. It seems it only works with protocols and enums?

I could code it by hand to work, but it seems the purpose of MetaCodable is to make something like this easy.

@robaho I am assuming you are talking about MetaProtocolCodable, you can use enums without having to use the MetaProtocolCodable. MetaCodable by itself provides untagged, external, internal and adjacent tagging enum decoding functionality. For your use case, it could look something like:

@Codable
struct Container
  let elements: [AOrB]

  @Codable
  @UnTagged
  enum AOrB {
    case b(name: String, location : String)
    case a(name: String)
  }
}

Please use discussion to ask these kind of queries. And use the proper templates when creating issues.

Sorry. I will use discussions in the future. I was able to resolve this using regular enums. I will post back when I get a moment.
