To calculate the height of your textview, i think you need to know the height of the text. So on your heightForRowAtIndexPath delegate method, calculate the text height and return it using this:

func heightWithConstrainedWidth(width: CGFloat, font: UIFont) -> CGFloat {
    let constraintRect = CGSize(width: width, height: CGFloat.max)

    let boundingBox = self.boundingRectWithSize(constraintRect, options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

    return boundingBox.height
}

You need to set the textview constrains, bottom, top, leading and trailing to 0, so they adjust to the size of the cell. The code was taken from here.

Set your UITextView number of line to 0. In the viewDidLoad of your Controller that contains the tableView use : 

 tableView.estimatedRowHeight = 55.0
 tableView.rowHeight = UITableViewAutomaticDimension
