I did UItableViewAutomationDimenension , but it didn't exactly work for me.

Answer 1

func heightForText(string: String, width: CGFloat, font: UIFont) -> CGFloat {
    let attrString = NSAttributedString(
        string: string,
        attributes: [NSFontAttributeName: font])
    let size = attrString.boundingRect(
    with: CGSize(width: width, height: CGFloat.greatestFiniteMagnitude), 
    options: NSStringDrawingOptions.usesLineFragmentOrigin, context: nil)
    return size.height
}

Answer 2

After doing some work on this, I found the solution.

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

        if msg1[indexPath.row].messageType == "image"{
            return 185.0
        }
        else{
            let attrString = NSAttributedString(
                string: msg1[indexPath.row].message!,
                attributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 16)])
            let size = attrString.boundingRect(
                with: CGSize(width: 200, height: CGFloat.greatestFiniteMagnitude),
                options: NSStringDrawingOptions.usesLineFragmentOrigin, context: nil)

            return size.height + 35
        }

So it gives a result output like this:

Anyway Thanks to all for your Answers...!!!
