How to change detailTextLabel height programmatically

I programmed an array into a tableView. When the cell utilizes more than one line for the detailTextLabel, the space in between the lines is small. I would like to know if there is any way to increase this height programmatically? Here is sample code I am using for the array.

cell.textLabel?.text = self.filtered[indexPath.row].coptic
cell.detailTextLabel?.text = self.filtered[indexPath.row].english
cell.textLabel?.font = UIFont(name:"CS Avva Shenouda", size:30)
cell.detailTextLabel?.font = UIFont(name: "Constantia", size:25)
cell.textLabel?.numberOfLines = 0
cell.detailTextLabel?.numberOfLines = 0
cell.detailTextLabel?.textColor = UIColor.darkGray

return cell

The table view needs to have an estimatedRowHeight and the tableView height as UITableViewAutomaticDimension.

I'm just putting my logic, not whole code. You can get height of string by below code

func height(withConstrainedWidth width: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
        let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

        return ceil(boundingBox.height)
    }

Change cellForRowAtIndexPath Method 

cell.detailTextLabel?.numberOfLines = 0 
let height = height(withConstrainedWidth:200, font:YourFont) // change width and font as per your requirement 
cell.detailTextLabel?.frame = CGRect(x: cell.detailTextLabel?.frame.origin.x, y: cell.detailTextLabel?.frame.origin.y, width: cell.detailTextLabel?.frame.size.width, height: height)

You can manage cell height according to detailTextLabel height 

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
{
   return 50 // You should put your code or logic that dynamic height based on heigh of label.
}
