body: <p>i have a UITableView which has multiple Prototype cells (with different identifiers ) and i have a separate class for my Cells ! this is how i've created my TableViewController :-</p>
  
  <pre><code>import UIKit
  class PostTableViewController: UITableViewController, UITextFieldDelegate {   
  var postArray = [["Sean Paul","Got To Love You"],["California","21 January 2018"],["Martin Garrix"]]
  
  override func viewDidLoad() {
      super.viewDidLoad()        
      tableView.rowHeight = UITableViewAutomaticDimension;
      tableView.estimatedRowHeight = 44
  }
  
  override func viewDidAppear(animated: Bool) {
  
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  
  
  override func numberOfSectionsInTableView(tableView: UITableView) -&gt; Int {
      // #warning Incomplete implementation, return the number of sections
      return 3
  }
  
  override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
      // #warning Incomplete implementation, return the number of rows
  
      print(postArray[section].count)
      return  postArray[section].count
  
  }
  
  override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
  
      var cell = UITableViewCell()
      if indexPath.section == 0 &amp;&amp; indexPath.row == 0{
  
          cell = tableView.dequeueReusableCellWithIdentifier("titleCell", forIndexPath: indexPath) as!
          MultiLineTextInputTableViewCell            
      }        
      if indexPath.section == 0 &amp;&amp;  indexPath.row == 1 {
           cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as!
          MultiLineTextInputTableViewCell            
          }
      if indexPath.section == 1 &amp;&amp;  indexPath.row == 0 {
          cell = tableView.dequeueReusableCellWithIdentifier("locationCell", forIndexPath: indexPath) as!
          MultiLineTextInputTableViewCell
      }
      if indexPath.section == 1 &amp;&amp; indexPath.row == 1 {
          cell = tableView.dequeueReusableCellWithIdentifier("timeCell", forIndexPath: indexPath) as!
          MultiLineTextInputTableViewCell

          MultiLineTextInputTableViewCell

      return cell
    }
  @IBAction func btnActionPost(sender: AnyObject) {        
      let indexPath = NSIndexPath(forRow: 1, inSection: 0)
     print( tableView.cellForRowAtIndexPath(indexPath)?.textLabel?.text) // here i tried to get the text of first cell but text is not in the cell's label it is inside the TextView which is inside UItableViewCell
      tableView.cellForRowAtIndexPath(indexPath)
    }
    }

  <p>and this is how i've created my TableViewCellController:-</p>
  
  <pre><code>  import UIKit

      let size = textView.bounds.size

      // Resize the cell only when cell's size is changed
      if size.height != newSize.height {
          UIView.setAnimationsEnabled(false)
          tableView?.beginUpdates()

    }
