Firstly, from storyboard or in your tableView Cell class set the textviews NumberOfLines = 0 .

In the height for row delegate have

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

In your viewdidLoad add these lines:

tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 140

In the tableViewController

 func updateCellHeight(indexPath: IndexPath, comment: String) {

    let currentCellLyricVal = self.traduzioneArray[indexPath.row]["rics"]
    tempIndexArray.removeAll()

    for (index,element) in traduzioneArray.enumerated() {

        let lyricVal = element["rics"]
        if currentCellLyricVal == lyricVal {
            tempIndexArray.append(index)
        }
    }
    for index in tempIndexArray {
        self.traduzioneArray[index]["ione"] = comment
    }
      tableView.reloadRows(at: [IndexPath(row: 11, section: 1),IndexPath(row: 13, section: 1)], with: UITableViewRowAnimation.none)
}

By having the lines set to 0 and auto dimension height the cells automatically resize. Please also verify that you set your custom cells delegate to self in yourcellForRowmethod.
