Realm Unique ID with Swift 2

In Realm is there a way to set a unique id for every object stored in the database? I don't necessarily need it to be auto incremented just unique every time. I was just wondering is there a way to do it in Swift 2 on iOS 8 or above? I know you can do it in objC.

To generate UUID for all objects in your Realm, you could create a superclass that generates the UUID:

class IdentifiableObject : Object {
    private(set) dynamic var uuid = NSUUID().UUIDString
}

Swift5

class IdentifiableObject : Object {
    private(set) dynamic var uuid = NSUUID().uuidString
}

While this works, it does come with a major catch, at least until realm supports read-only attributes. When updating objects, you will have to first obtain the stored object before saving.
