Can't parse JSON array with JSONDecoder in Swift 4

Question

I have a JSON array I need to parse and I choose to use JSONDecoder to parse it.

JSON array looks like this:

[{\"Id\":0,\"Key\":\"key0\",\"Name\":\"n         


        

Answer 1

Remove the initial values for the constant properties

class Result: Codable{
    let title: String
    let id: Int
    let key: String
    let name: String

    // ...
}

(or make the properties variable). Initialized constant properties can not be set by the JSON decoder.
