title: How to type into a UITextView inside a XCTestCase
body: <p>How do you type into a <code>UITextView</code> inside a <code>XCTestCase</code>? The <code>UITextView</code> is the first responder so it already had focus and the keyboard is up.</p>
  
  <p>I've tried:</p>
  
  <pre><code>app.typeText("footer")
  app.textViews.element(boundBy: 0).typeText("foobar")
  app.links.element(boundBy: 0).typeText("foobar")
  </code></pre>
  
  <p>for some reason <code>app.textViews.count</code> always returns <code>0</code>? </p>
