So I have simple structs like this:
struct Library: Codable {
let domain: String
let unit: String
}
and it’s super-simple to serialize. Yay.
But:
struct LibraryGroup : Codable { // I wish...
let libraries: [Library]
let someDict: [String : Any]
}
So what I’m looking for is something where if the values in someDict are
themselves Codable, I can serialize things, and if they’re not, I can’t. In my
previous scheme, I was using NSKeyedArchiver to serialize everything, manualy,
including someDict; in trying to switch to Codable I ran smack into the fact
that Codable wants to know what all the types are, in advance.
Am I just stuck? How do I get the best of both worlds, where the compiler can
make use of the fact that it can see the data types of my structures, while
still being able to serialize heterogenous data like is found in LibraryGroup?
Is my only alternative to write a custom coder for LibraryGroup? Is there any
hope I could teach Codable what to do with
[String: Any]
?
