I’m trying to decode two slightly different JSON API responses to the same Codable type, Account. Mapping userResponse.json’s uid to id is trivial, but extracting the nested user is stumping me.

Any suggestions would be greatly appreciated!

example.swift

struct Account: Codable {
  typealias ID = String
  var id: ID
  var uid: String?
  var avatar: String?
  var name: String
  
  init(from decoder: Decoder) throws {
    let values = try decoder.container(keyedBy: CodingKeys.self)
    if let id = try values.decodeIfPresent(String.self, forKey: .uid) {
      self.id = id
    } else {
      self.id = try values.decode(String.self, forKey: .id)
    }
    
    self.avatar = try values.decode(String.self, forKey: .avatar)
    self.name = try values.decode(String.self, forKey: .name)
  }
}

teamResponse.json

{
  "id": "team_ba3d8621-3c66-421a-8c46-f1ea6dfa27a1",
  "name": "Acme, Inc.",
  "avatar": "02d2608a-7526-4821-ad27-3d329b674dc8",
}

userResponse.json

{
  "user": {
    "uid": "f5f5e86e-b75e-4cc7-a3be-ddeecbd9c7a6",
    "name": "John Appleseed",
    "avatar": "9283df3f-54d3-4329-8d6b-dbc90f8a9a38"
  }
}
