override func viewDidLoad() {
    super.viewDidLoad()

    textview.delegate = self
    
}

@IBAction func sampleButton(_ sender: Any) {
 
    
}

func textViewDidChange(_ textView: UITextView) {
    let size = CGSize(width: textView.frame.width, height: 200)
    let estimateSize = textView.sizeThatFits(size)
    
    guard textView.contentSize.height < 100.0 else { textview.isScrollEnabled = true; return}
    
    textview.isScrollEnabled = false
    textview.constraints.forEach { (constriant) in
        if constriant.firstAttribute == .height {
            constriant.constant = estimateSize.height
        }
    }
}

can you provide some code of what you have already. just to give us a bit of context — colin, Apr 07 '21 at 12:07

I'm struggling to understand what the problem is. I'm not sure I understand the question, and the code supplied doesn't seem to be related to whatever the question is. — flanker, Apr 07 '21 at 12:41

As seen on other posts it has to do with how spaces are handled (). You can add the following delegate code to replace spaces with non breaking spaces :

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText string: String) -> Bool {
    if (textView == self.textView) {
        let oldString = textView.text!
        let newStart = oldString.index(oldString.startIndex, offsetBy: range.location)
        let newEnd = oldString.index(oldString.startIndex, offsetBy: range.location + range.length)
        let newString = oldString.replacingCharacters(in: newStart..<newEnd, with: string)
        textView.text = newString.replacingOccurrences(of: " ", with: "\u{00a0}")
        return false;
    } else {
        return true;
    }
}
