@DocumentID when receiving data from source that isn't Firestore

[Alex-Coetzee]

Lets say we have a Struct

struct Person : Identifiable, Codable {

     @DocumentID var id : String?

     var first_name : String?

}

In most cases I am querying Firestore directly making the @documentid property wrapper very useful.

However, when utilising the newer Functions API I sometimes receive data from the server, which of course does not include a Document ID

I have simplified the code example to make it easier to follow so let's assume I am sending the COdable as a Person and receiving a Person type back from the function, the issue is that encoding fails due to the @documentid wrapper.

let response = try await Functions.functions().httpsCallable("savePerson", requestAs: Person.self, responseAs: Person.self)

Is there a way to specificy to ignore the DocumentID wrapper in this scenario when receiving the data back from the server?

Is there a way to customise it using the coding keys or a custom decoder?

Please could you point me in the right direction as it would be much appreciated.

You will probably need to split the struct up into two separate types:

struct CorePerson: Codable {
  let firstName = "Peter"
}

struct Person: CorePerson, Identifiable, Codable {
  @DocumentID var id : String
}

You can't inherit structs. 😊
