The user in my app can create multiple “Song” entities and add to a playlist in the range of 10k to 100k.

I don’t think I can use NSBatchInsertRequest to save them until they press “Done” since that will save them permanently to disk straight away.

I want the user to have the option to rollback to their previous state of their playlist by pressing on “Cancel” button.

How do I handle this situation?

func savePlaylist() {
let newPlaylist = Playlist(context: moc)
                        newPlaylist.name = "Test 1"
                        newPlaylist.id = UUID()
                        
                        var array: [Any] = []
                        for i in 0...100000 {
                            let song = Song(context: moc)
                            song.name = "Song" + "(i)"
                            song.fileExtension = "mp3"
                            song.artist = "Some artist"
                            array.append(song1)
                        }
                        
                        newPlaylist.songs = NSOrderedSet(array: array)
                        
                        try? moc.save()
}
