How do I prevent adding duplicates to a list in RealmSwift ? I have my User as a realm object, but the real data source is a server (simply caching the user locally with Realm). When I get the current user data from my server, i want to make sure that my user stored in realm has all the playlists coming from the server (and that their in sync wrt list of tracks and etc.). I'm worried that if i loop over those lists from the server, appending to myUser.playlists , that I may end up adding the same playlist to the user's list of playlists multiple times. class User: Object { dynamic var name = "

I have a video player in my app. There is a list of videos in a collection view. If you tap on one of the cells, a new view controller appears to play the selected video. Also, you can cycle through all of the videos from the collection view in this new view controller because the entire list is passed. The problem is: When the user is in the PlayerVC , they can unfavorite a Video . If they do this, I delete the Video object from Realm.

I have done R&D for limit in query with no success. There is one way with which to paginate data in Realm with sub list but no success with that. It shows duplicate value in it. Here is what I attempted for pagination.
