         The persistent container for the application. This implementation
         creates and returns a container, having loaded the store for the

You can make a deep copy of your object via the following extension functions:

import UIKit
import Realm
import RealmSwift

protocol RealmListDetachable {

    func detached() -> Self
}

A great Swift implementation (updated for Xcode 7) using extensions, pulled together from a variety of different answers and places. You will also need the string extensions at the end.

Use:

let hexColor = UIColor(hex: "#00FF00")

NOTE: I added an option for 2 additional digits to the end of the standard 6 digit hex value for an alpha channel (pass in value of 00-99). If this offends you, just remove it. You could implement it to pass in an optional alpha parameter.
