CodableDictionary

Struct to make simple [String: Any] dictionaries conform to Codable.

Usage

Decoding

let data1: Data = try! Data(contentsOf: Bundle.main.url(forResource: "test", withExtension: "json")!)
let dict = try? JSONDecoder().decode(CodableDictionary.self, from: data)
let name = dict?["name"]

Encoding

CodableDictionary can be initialised with [String: Any].

let dict = CodableDictionary(value: ["foor": 233, "nested": ["n1": "hallo", "n2": "welt", "nested": ["n1": "hallo", "n2": "welt"]]])
let encodedData: Data = try! JSONEncoder().encode(dict)
let jsonString = String(data: encodedData, encoding: .utf8)

Encoding of custom models is also supported. So you can simply wrap models into a dictionary.

struct User: Codable {
	let name: String
}
        
let user = User(name: "Stefan")
        
var userDict = CodableDictionary(value: ["user": user])
userDict.additionalEncoding = { (container, codingKey, value) in
	if let user = value as? User {
		try container.encode(user, forKey: codingKey)
	}
}
        
let encodedData: Data = try! JSONEncoder().encode(userDict)
let jsonString = String(data: encodedData, encoding: .utf8)

Limitations

Since CodableDictionary has to know the type of model which has to be decoded/encoded, Any has to be one of the following types:

supported types of Any
String, [String]
Bool, [Bool]
Int, [Int]
Double, [Double]
