UITableView disable swipe to delete, but still have delete in Edit mode?

You need to implement the CanEditRowAt function.

You can return .delete in the EditingStyleForRowAt function so you can still delete in editing mode.

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    if tableView.isEditing {
        return true
    }
    return false
}

func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCell.EditingStyle {
    return .delete
}

Ok, it turns out to be quite easy. This is what I did to solve this:

Objective-C

- (UITableViewCellEditingStyle)tableView:(UITableView *)aTableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Detemine if it's in editing mode
    if (self.tableView.editing)
    {
        return UITableViewCellEditingStyleDelete;
    }

    return UITableViewCellEditingStyleNone;
}

Swift 2

override func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle {
    if tableView.editing {
         return .Delete
    }

    return .None
}

Swift 3

override func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCellEditingStyle {
    if tableView.isEditing {
        return .delete
    }

    return .none
}

You still need to implement tableView:commitEditingStyle:forRowAtIndexPath: to commit the deletion.

Just to make things clear, swipe-to-delete will not be enabled unless tableView:commitEditingStyle:forRowAtIndexPath: is implemented.

While I was in development, I didn't implement it, and therefore swipe-to-delete wasn't enabled. Of course, in a finished app, it would always be implemented, because otherwise there would be no editing.
