I have a file with few records on separate lines. I have created a tableview that populates with the records from the file. Now I have update and delete buttons. If I update or delete the selected record I am able to update or delete ONLY in the table itself but NOT the file that is used for the records. SO every time I update or delete and then close app and then open again the records come back as the same SINCE the file ITSELF was not updated.
