coredata object mutablecopy in swift

 Problem:

I want to copy my coredata object as another object and then change the current object with new updates.After that i want to save or discra the changes.If i save the change then want to know the old object before changed.

How can i get that?

Solution:

You have to add the extension function as below to your coredata entity.

func copyObject() -> Obj {

        var newObj = Obj(context: getContext())

        var newTitle = ObjTitle(context: getContext())

        newObj.title = newTitle

        newObj.title?.name = self.title?.name

        newObj.desc = self. desc

        return newObj

    }
