Using non final class Decodable #118
Description
I have an issue since i last updated my pods and Himotoki got upgraded to 2.0.0.
I no longer can use DecodedType and I have the following scenario I'd appreciate if you can help me fix.
I am subclassing a class which I need to be decodable like such:
class A: Decodable {
var type : Int = 0
var title: String = ""
init (e: Extractor) {
type = try! e <| "type"
title = try! e <| "title"
}
static func decode(e: Extractor) throws -> A {
let type : Int = try e <| "type"
switch type {
case 0:
return B(e: e)
case 1:
return C(e: e)
case 2:
return A(e: e)
}
}
}
class B: A {
var total : Double = 0.0
override init(e: Extractor) {
total = try! e <| "total"
super.init(e: e)
}
}
class C: A {
var link : String = ""
override init(e: Extractor) {
link = try! e <| "link"
super.init(e: e)
}
}
I now have a compiler error on this line static func decode(e: Extractor) throws -> A which says Method 'decode' in non-final class 'A' must return 'Self' to conform to protocol 'Decodable'
Thank you for your help in advance! Great library 👍 !
