UITextView in Cell Swift

I have been messing with these constraints for hours and cannot figure this out. I need to have Dynamic cell height with my text view.

enter image description here enter image description here

As you can see its overlapping my time stamp. As of right now I have zero(no) constraints on the time stamp. I have tried every combination possible to make this work and I cant get it.

Also am using

   override func viewDidLoad() {
        super.viewDidLoad()



        //TableView Cell word wrap (Dynamic Text)
        self.tableView.dataSource = self
        self.tableView.delegate = self
        self.tableView.estimatedRowHeight = 78
        self.tableView.rowHeight = UITableViewAutomaticDimension

For Swift 3.1, 4.0

It will be achieved by setting constraints and UITableViewAutomaticDimensions.

Step 1:

Step 2:

Step 3:

Step 4:

Remove Scrolling for UITextView

enter image description here

Step 5:

Add Below code,

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

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

    return UITableViewAutomaticDimension
}

Note:

If you have UILabel then, Replace UITextView to UILabel from above solution and label.numberOfLines = 0.

If your cell height is dependent on text size then follow this: Add the method in your ViewController.swift

    func calculateHeight(inString:String) -> CGFloat {
         let messageString = inString
         let attributes : [String : Any] = [NSFontAttributeName : UIFont.systemFont(ofSize: 15.0)]

     let attributedString : NSAttributedString = NSAttributedString(string: messageString, attributes: attributes)

     let rect : CGRect = attributedString.boundingRect(with: CGSize(width: 222.0, height: CGFloat.greatestFiniteMagnitude), options: .usesLineFragmentOrigin, context: nil)

      let requredSize:CGRect = rect
      return requredSize.height
}

Set the width of your text label Then call this function:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
            heightOfRow = self.calculateHeight(inString: conversations[indexPath.row].description)

            return (heightOfRow + 60.0)
    }

For Basic cell:

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

This function will not work for custom cells.

If your cell height is dependent on image height, then return image height + someFloatValueAccordingToYourChoice.

Hope it will work.

User vertical spacing between the timeStamp and the message, and set the constant to >=2
