You need to give more context to expect any body to come back to you with some help.

This happen if you play with the scroll of your UITableView while the data source is mutating datas (deleting some, let's say that for example you're doing a search that will return 0 result, when you're actually displaying a search that gave already 10 results) if you are using Realm with List or Results.
