JSON 4 Swift bug

container.swift

// For this JSON: 
{
    "success": true,
    "payload": {
        "asks": [{
            "book": "btc_mxn",
            "price": "5632.24",
            "amount": "1.34491802"
        },{
            "book": "btc_mxn",
            "price": "5633.44",
            "amount": "0.4259"
        },{
            "book": "btc_mxn",
            "price": "5642.14",
            "amount": "1.21642"
        }],
        "bids": [{
            "book": "btc_mxn",
            "price": "6123.55",
            "amount": "1.12560000"
        },{
            "book": "btc_mxn",
            "price": "6121.55",
            "amount": "2.23976"
        }],
        "updated_at": "2016-04-08T17:52:31.000+00:00",
        "sequence": "27214"
    }
}

// The generated model on the base should be:

struct Json4Swift_Base : Codable {
	let success : Bool?
	let payload : Payload?

	enum CodingKeys: String, CodingKey {
		case success = "success"
		case payload = "payload"
	}

	init(from decoder: Decoder) throws {
		let values = try decoder.container(keyedBy: CodingKeys.self)
		success = try values.decodeIfPresent(Bool.self, forKey: .success)
    payload = try values.decodeIfPresent(Payload.self, forKey: .payload)// Payload(from: decoder)
	}
}

And not:

struct Json4Swift_Base : Codable {
	let success : Bool?
	let payload : Payload?

	enum CodingKeys: String, CodingKey {
		case success = "success"
		case payload
	}

	init(from decoder: Decoder) throws {
		let values = try decoder.container(keyedBy: CodingKeys.self)
		success = try values.decodeIfPresent(Bool.self, forKey: .success)
        payload = try Payload(from: decoder)
	}

}

Fixed
