Answer 1

I have the issue with resizing label so I nee just to do
chatTextLabel.text = chatMessage.message chatTextLabel?.updateConstraints() after setting up the text

// full code

func setContent() {
    chatTextLabel.text = chatMessage.message
    chatTextLabel?.updateConstraints()

    let labelTextWidth = (chatTextLabel?.intrinsicContentSize().width) ?? 0
    let labelTextHeight = chatTextLabel?.intrinsicContentSize().height

    guard labelTextWidth < originWidth && labelTextHeight <= singleLineRowheight else {
      trailingConstraint?.constant = trailingConstant
      return
    }
    trailingConstraint?.constant = trailingConstant + (originWidth - labelTextWidth)

  }
