lhTextView.activeLineViewColor = .blue
lhTextView.errorColor = .red
lhTextView.title = "Demo"
lhTextView.placeholder = "Placeholder"
lhTextView.defaultHeight = 30
lhTextView.lineViewHeight = 1
lhTextView.isLTRLanguage = true
lhTextView.errorFont = UIFont.boldSystemFont(ofSize: 13)
lhTextView.titleFont = UIFont.italicSystemFont(ofSize: 13)
lhTextView.placeHolderFont = UIFont.systemFont(ofSize: 13)

Show Error:

func textViewDidChange(_ textView: UITextView) {
   if let int = Int(textView.text) {
      lhTextView.errorMsg = ""
   }else {
      lhTextView.errorMsg = "Error"
   }
}
