Just because it is not visible on your screen doesn't mean it is not visible. What is visible and not visible is decided by your tableView frame. Check your table view frame. Also, elaborate your question with screenshots and code.

Use prefetch data source property for pagination.

The system calls this method to prepare cells ahead of time, so scrolling is smoother and more responsive. If you want to fetch more data as the user scrolls down/up you should rather implement UITableViewDelegate method tableView(_:willDisplay:forRowAt:) - this method is called just before the cell is displayed to the user.
