I'm trying to understand how could I parse this multiple container JSON to an object. I've tried this approach (Mark answer), but he explain how to solve it using one-level container. For some reason I can't mimic the behaviour for multiple containers.
{
"graphql": {
"shortcode_media": {
"id": "1657677004214306744",
"shortcode": "BcBQHPchwe4"
}
}
}
class Post: Decodable {
enum CodingKeys: String, CodingKey {
case graphql // The top level "user" key
case shortcode_media
}
enum PostKeys: String, CodingKey {
case id
}
required init(from decoder: Decoder) throws {
let values = try decoder.container(keyedBy: CodingKeys.self)
let post = try values.nestedContainer(keyedBy: PostKeys.self, forKey: .shortcode_media)
self.id = try post.decode(String.self, forKey: .id)
}
var id: String
}
I'm getting:
Swift.DecodingError.Context(codingPath: [], debugDescription: "Cannot get KeyedDecodingContainer<PostKeys> -- no value found for key \"shortcode_media\"", underlyingError: nil))
Any help will be much appreciated, thank you!
