So let's use our newly discovered knowledge that. The compiler generates a. CodingKeys type nested inside. You learned what the. Now that you've seen how to decode data, let's take a look at doing the opposite; encoding structs into JSON data. I would have thought that the following would work: enum Direction: Codable {. Using the example above, we can use the same structure and conform to the. Swift: Does not conform to protocol NSCoding. Decoder as both the structures are already. But there is power in this little container! Does not conform to protocol hashable. That's a good way to find out what's missing, even if you're eventually going to delete the stubs and use synthesized conformance. Element' does not conform to protocol 'Decodable'. Extension Role: Encodable {... // case _1}}. In this case, that means we would define a struct that has three properties with types. In this case, I only want to decode so I'm declaring my struct as.

TopResults: enum SuggestionKind: Codable { case terms(TermSuggestion) case topResults(TopResultsSuggestion) enum CodingKeys: String, CodingKey { case kind} enum SuggestionsKind: String, Codable { case terms case topResults} public init(from decoder: Decoder) throws { let values = try ntainer(keyedBy:) let kind = try (, forKey:) switch kind { case let termSuggestion = try TermSuggestion(from: decoder) self = (termSuggestion) case.
