Question

I\'m struggling to get my CoreData objects into JSON so that I can use it to send to a web server.

This is how I currently fetch my objects from CoreData:

You can convert your NSManageObject subclass object into dictionary by using following code

let record = recArray[index]
        let keys = Array(record.entity.attributesByName.keys)
        let dict = record.dictionaryWithValues(forKeys: keys)

After that you can use jsonserialization to convert that dictionary into json object

do{
        let jsonData = try JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted)
        let reqJSONStr = String(data: jsonData, encoding: .utf8)
        print(reqJSONStr!)
    }catch{

    }

Hope this will help.
