The last cell in a tableview cell should not be deleted when trying to remove from array in swift

Question

Entering data into textfield, when clicked on add button then that textfield text gets appended into an array and is displayed in table cell. Now max 5 data i can append and show it in a cell which is working but in a cell there is a delete button which deletes the data appended. Now i want that when deleting the entry from cell one by one, the last remaining data in a cell should not be deleted and a toast message should be displayed saying that mandatory data cannot be deleted. Right now i am removing the data at a given index but all data is being deleted right now beacuse i dont know which condition to put for last cell not being deleted. Please help me

My code :

var rowIndex = Int()

@objc func deletecontact(sender: uibutton)
{
   rowIndex = sender.tag
   Self.openDeleteDialogPopup()
}

IBAction weak var func yesBtnClicked(sender:uibutton)
{
   MyArr.remove(at: rowIndex)
   Mytableview.reloaddata()
}

In the function where you are deleting the item from the array you need to check on if it has a count greater than 1 or not, if it is not, then you show the toast. If it is then you delete the row

@IBAction weak var func yesBtnClicked(sender:UIButton) {
   guard MyArr.count > 1 else { //If we have more than one item, then don't enter the else block
   //showToastHere
    return
   }
   MyArr.remove(at: rowIndex)
   MyTableview.reloadData()
}
