Realm Object JSONDictionary method not working in Swift

[marksbren]

I have been trying to implement this on my current Swift project, but cannot get it working. Here is my model:

//
//  RealmComment.swift

import Foundation
import RealmSwift

class RealmComment: Object {
    dynamic var text: String?
    dynamic var id: String?
    dynamic var createdAt: Double = 0.00
    dynamic var updatedAt: Double = 0.00
    dynamic var user: RealmUser?
    dynamic var post: RealmPost?

    override static func primaryKey() -> String? {
        return "id"
    }

    func JSONOutboundMappingDictionary() -> NSDictionary {
        return [
            "id": "objectId",
            "createdAt": "createdAt",
            "updatedAt": "updatedAt",
            "user":"user",
            "post":"post",
            "text":"text"
        ]
    }

    func JSONInboundMappingDictionary() -> NSDictionary {
        return [
            "id": "objectId",
            "createdAt": "createdAt",
            "updatedAt": "updatedAt",
            "user":"user",
            "post":"post",
            "text":"text"
        ]
    }    
}

I am then trying to convert an object to JSON Dictionary using this (to convert a comment from one RealmComment (Realm+JSON) to an MBComment (ObjectMapper)

    class func realmCommentToMbComment(realmComment: RealmComment) -> MBComment {
        var newMbComment = MBComment()
        let realm = try! Realm()
        try! realm.write {

            let JSONString = realmComment.JSONDictionary
            newMbComment = Mapper<MBComment>().map(JSONString)! //this is using ObjectMapper

        }
        return newMbComment

    }

However, this will not compile and gives me an error "Value of type RealmComment has no member JSONDictionary".

I guess the problem is in class RealmComment: Object. You should be subclassing RLMObject
