How to remove cells from a UITableView
Swift version: 5.0
It's easy to delete rows from a table view, but there is one catch: you need to remove it from the data source first. If you don't do this, iOS will realize there's a mis-match between what the data source thinks should be showing and what the table view is actually showing, and you'll get a crash.
So, to remove a cell from a table view you first remove it from your data source, then you call deleteRows(at:) on your table view, providing it with an array of index paths that should be zapped. You can create index paths yourself, you just need a section and row number.
Here's some example code to get you started:
objects.remove(at: 0)
let indexPath = IndexPath(item: 0, section: 0)
tableView.deleteRows(at: [indexPath], with: .fade)HACKING WITH SWIFT LIVE This July is a new two-day event where you'll be inspired by great speakers on day one then learn all the amazing new features from WWDC on day two – click here for more information and tickets.
