How_To_SwiftyJSON

    // This very useful code parses a `.json` file using the library SwiftyJSON.

    // Add this in a class, maybe in your Data Manager:
    class func addDefaultEntities() {
        if let file = NSBundle(forClass:AppDelegate.self).pathForResource(JSON.Constants.FileName, ofType: JSON.Constants.Type) {
            if let data = NSData(contentsOfFile: file) {
                for (index: String, bookJSON: JSON) in JSON(data:data) {
                    let dict = bookJSON.dictionaryObject
                    // do something with the dictionary
                }
            }
        }
    }
    
    // And this in your extensions file:
    extension JSON {
        struct Constants {
            static let FileName                 = 		"your_data_local_filename"
            static let Type                     = 		"json"
        }
    }
