Is it possible to declare generics inside Decodable model

Question

Here is my model class

struct ErrorData: Decodable {
    let code : Int
    let message : String
    let data : [ErrorDataFields]
}

i want to have ErrorDataFields to be array and object like

struct ErrorData: Decodable {
        let code : Int
        let message : String
        let data : [ErrorDataFields]
    }

AND

struct ErrorData: Decodable {
        let code : Int
        let message : String
        let data : ErrorDataFields
    }

I'd suggest to give it a try before posting a question, in case you face an issue you can ask about it. — Ahmad F, Jul 29 '19 at 08:41

We can use a generic type with Decodable. Only thing is the generic type should also conform to Decodable.

struct ErrorData <T : Decodable> : Decodable {
    let code : Int
    let message : String
    let data : T
}
