问题 Here's my code: class LoginUserResponse : Codable { var result: String = "" var data: LoginUserResponseData? var mess: [String] = [] } public class LoginUserResponseData : Codable { var userId = "0" var name = "" } Now, calling the server API I'm parsing response like this (using Stuff library to simplify parsing): do { let loginUserResponse = try LoginUserResponse(json: string) } catch let error { print(error) } When I enter the correct password I'm getting an answer like this: {"result":

问题 I have a JSON with an array of values: [ { "tag": "Foo", … }, { "tag": "Bar", … }, { "tag": "Baz", … }, ] I want to decode this array into an array of struct s where the particular type depends on the tag: protocol SomeCommonType {} struct Foo: Decodable, SomeCommonType { … } struct Bar: Decodable, SomeCommonType { … } struct Baz: Decodable, SomeCommonType { … } let values = try JSONDecoder().decode([SomeCommonType].self, from: …) How do I do that? At the moment I have this slightly ugly

问题 In SwiftUI beta 5, Apple introduced the @Published annotation. This annotation is currently blocking this class from conforming to the Codable protocols. How can I conform to these protocols so I can encode and decode this class to JSON? You can ignore the image property for now. class Meal: ObservableObject, Identifiable, Codable { enum CodingKeys: String, CodingKey { case id case name case ingredients case numberOfPeople } var id = Globals.generateRandomId() @Published var name: String = ""

"direction": { "prediction": [ { "affectedByLayover": "true", "block": "241", "dirTag": "loop", "epochTime": "1571785998536", "isDeparture": "false", "minutes": "20", "seconds": "1208", "tripTag": "121", "vehicle": "1698" }, {
