I have UITableViewController and after user pres desired button, I have "full edit" mode. To enable this, I call this:

@objc func btnEditPressed(sender: UIButton) {
   sender.isSelected = !self.isEditing
   self.setEditing(!self.isEditing, animated: true)

   self.tableView.beginUpdates()
   self.tableView.endUpdates()
}

for each UITableViewCell, I have override func setEditing(_ editing: Bool, animated: Bool) method. In this, I hide some parts of cell in "full edit" mode.

Now, when the user swipe single table row, I show the delete button. However, in this "delete row mode" I dont want to hide any information from the cell. The problem is, that the same override func setEditing(_ editing: Bool, animated: Bool) for the cell is called as in the first case, leading to hiding cell content.

Is there an easy way, how to solve this, or I have to keep weak reference to UITableViewController and check the mode from the cell myself?

You have two options to handle this.

1. Check showingDeleteConfirmation in the cell's setEditing method.
2. Override willTransition(to:) and didTransition(to:) in your cell class.

If your table view is not in editing mode and the user performs a swipe-to-delete gesture, then your cell will experience the following sequence:

• willTransition(to:) will be called with the mask including the value UITableViewCell.StateMask.showingDeleteConfirmation
• setEditing will be called with editing set to true. The cell's showingDeleteConfirmation will be equal to true
• didTransition(to:) will be called with the mask including the value UITableViewCell.StateMask.showingDeleteConfirmation

So the simplest solution is to update your cell's setEditing:

override func setEditing(_ editing: Bool, animated: Bool) {
    super.setEditing(editing, animated: animated)

    if showingDeleteConfirmation {
        // User did a swipe-to-delete
    } else {
        // The table view is in full edit mode
    }
}
