title: Assign text in "Text View" to a variable makes app crash
body: <p>basically when the code below runs, the app crashes and I can't figure out why. I think I may be assigning the text inside of "test1" to the variable "new1var" in the wrong way, but I'm not sure.</p>
  
  <pre><code>@IBOutlet weak var test: UITextField! //text field
  @IBOutlet weak var test1: UITextView! //text view
  
  
  @IBAction func submit(_ sender: Any) { //when a button is pressed
  
      let newvar = test.text
      let new1wvar = test1.text     //this line is where it crashes
  }
  </code></pre>
  
  <p>Thank you so much for your help (I'm new to swift)!</p>
