Well it’s a common IntOrString problem. You could just make your property type an enum that can handle either String or Int. enum IntOrString: Codable { case int(Int) case string(String) init(from decoder: Decoder) throws { let container = try decoder.singleValueContainer() do { self = try .int(container.decode(Int.self)) } catch DecodingError.typeMismatch { do { self = try … Read more
There’s a subtle, but important difference between these two lines of code: // Exhibit 1 foo = try container.decode(Int?.self, forKey: .foo) // Exhibit 2 foo = try container.decodeIfPresent(Int.self, forKey: .foo) Exhibit 1 will parse: { “foo”: null, “bar”: “something” } but not: { “bar”: “something” } while exhibit 2 will happily parse both. So in … Read more
As you said, your json array is multi-type but you are trying to decode all into String. Default conformance of String to Decodable does not allow that. The only solution comes into my mind is to introduce new type. struct IntegerOrString: Decodable { var value: Any init(from decoder: Decoder) throws { if let int = … Read more
You can try struct Root: Codable { let description,id: String let group,groupDescription: String? let name: String let value: MyValue enum CodingKeys: String, CodingKey { case description = “Description” case group = “Group” case groupDescription = “GroupDescription” case id = “Id” case name = “Name” case value = “Value” } } enum MyValue: Codable { case … Read more
Quantum Value First of all you can define a type that can be decoded both from a String and Int value. Here it is. enum QuantumValue: Decodable { case int(Int), string(String) init(from decoder: Decoder) throws { if let int = try? decoder.singleValueContainer().decode(Int.self) { self = .int(int) return } if let string = try? decoder.singleValueContainer().decode(String.self) { … Read more
The key is in how you define the CodingKeys property. While it’s most commonly an enum it can be anything that conforms to the CodingKey protocol. And to make dynamic keys, you can call a static function: struct Category: Decodable { struct Detail: Decodable { var category: String var trailerPrice: String var isFavorite: Bool? var … Read more
