title: Showing Multiple Lines in a TextView
body: <p>I am doing a project in Swift and I am reading data from a file and trying to display it in a text view. I am reading it line by line. For example, if I have 10 lines in the file the text view only shows the last one. And I'd like to see them all.</p>
  
  <p>How can I do that?</p>
  
  <p>I am doing it like this:</p>
  
  <pre><code>if let aStreamReader = StreamReader(path:    "historic.txt") {
      defer {
          aStreamReader.close()
      }
  
  while let line = aStreamReader.nextLine() {
      MyTextView.text = "\(line)"
  }
  </code></pre>
  
  <p>The code is working in the console, because if I make a print every show up ok.
  But in the text view only last line is visible.</p>
