codable

the data I'm getting from an API returns a single object but when there's multiple objects, it returns an array in the same key. With the current model (struct) I'm working with, the decoding fails when an array shows up. These results are randomly ordered, meaning I can't know when I will be served an object or array. Is there a way to create a model that takes this fact into account and can assign the correct type to cast for the value ('String' or '[String]') so that the decoding continues without problem? This is an example of when an object is returned: { "firstFloor": { "room": "Single

Using Swift4, iOS11.1, Xcode9.1, Using the new Swift4 typealiase "Codable" works well for JSON-decoding (as explained here or here or in many other contributions). However, as it comes to XML-parsing, I couldn't find any information on whether this "Codable" protocol could also be used for XML-decoding. I tried to use the XMLParser (as can be seen in code-excerts below). But I failed to used the "Codable" protocol as to simplify the XML-parsing process. How would I have to use the Codable-protocol exactly to simplify XML-parsing ?? // the Fetching of the XML-data (excert shown here with a

I've got some JSON messages coming in over a websocket connection. // sample message { type: "person", data: { name: "john" } } // some other message { type: "location", data: { x: 101, y: 56 } } How can I convert those messages into proper structs using Swift 4 and the Codable protocol? In Go I can do something like: "Hey at the moment I only care about the type field and I'm not interested in the rest (the data part)." It would look like this type Message struct { Type string `json:"type"` Data json.RawMessage `json:"data"` } As you can see Data is of type json.RawMessage which can be parsed

I am working on mix and match iOS source code. I have implemented codable for swift data model class which reduces the burden of writing parser logic. I tried to conform my objective c class to codable protcol which in turn thrown an error "Cannot find protocol declaration for 'Codable'". Is there any way to use this swift protocol into objective c class? Or Is there any other objective c api that provides the same capability as Codable? The idea is to make the parsing logic same across swift and objective c classes. Yes, you can use Codable together with Obj-C. The tricky part is that because

Swift 4 has Codable and it's awesome. But UIImage does not conform to it by default. How can we do that? I tried with singleValueContainer and unkeyedContainer extension UIImage: Codable { // 'required' initializer must be declared directly in class 'UIImage' (not in an extension) public required init(from decoder: Decoder) throws { let container = try decoder.singleValueContainer() let data = try container.decode(Data.self) guard let image = UIImage(data: data) else { throw MyError.decodingFailed } // A non-failable initializer cannot delegate to failable initializer 'init(data:)' written
